本発明に係る液圧制御装置は、制御対象物に送られる作動液の流量を調整し、この作動液の液圧を変化させることで、制御対象物の動作を制御するものである。この液圧制御装置は、ポンプ等で圧送されてきた作動液を内部で流動させる液圧回路体と、その作動液の流量を調整する少なくとも１つの電磁弁と、を備える。その液圧回路体には、作動液の流動経路である液圧回路が内部に形成されている。電磁弁は、その液圧回路における作動液の流量を調整する。   The hydraulic pressure control device according to the present invention controls the operation of the controlled object by adjusting the flow rate of the working fluid sent to the controlled object and changing the hydraulic pressure of the working fluid. This hydraulic pressure control device includes a hydraulic circuit body that causes hydraulic fluid pumped by a pump or the like to flow therein, and at least one electromagnetic valve that adjusts the flow rate of the hydraulic fluid. In the hydraulic circuit body, a hydraulic circuit that is a flow path of the working fluid is formed inside. The electromagnetic valve adjusts the flow rate of the hydraulic fluid in the hydraulic circuit.

ここで、制御対象物は、作動液の液圧を利用して動作するものであれば、如何様なものであってもよい。そして、作動液は、その制御対象物を動作させるためのものであれば、如何様なものであってもよい。本実施形態では、自動車等の車両に搭載されている自動変速機を制御対象物として例示する。このため、作動液としては、自動変速機の動作と潤滑を担う作動油（ＡＴＦ：Automatic Transmission Fluid）が用いられる。そこで、以下においては、制御対象物を自動変速機と読み替えて説明を続けることにする。また、以下においては、作動液を作動油と読み替え、かつ、液圧を油圧と読み替えて説明する。   Here, the control object may be any object as long as it operates using the hydraulic pressure of the hydraulic fluid. The hydraulic fluid may be any fluid as long as it is for operating the control object. In the present embodiment, an automatic transmission mounted on a vehicle such as an automobile is exemplified as a control object. For this reason, as the hydraulic fluid, hydraulic fluid (ATF: Automatic Transmission Fluid) responsible for the operation and lubrication of the automatic transmission is used. Therefore, in the following description, the control object is read as an automatic transmission and the description is continued. In the following description, the hydraulic fluid is read as hydraulic oil, and the hydraulic pressure is read as hydraulic pressure.

図１及び図２の符号１は、本実施形態の油圧制御装置を示す。この油圧制御装置１は、油圧回路体１０と電磁弁２０と制御ユニット３０とを備える。本図の油圧制御装置１は、油圧回路体１０の一部を抜粋したものである。   Reference numeral 1 in FIGS. 1 and 2 denotes a hydraulic control apparatus according to the present embodiment. The hydraulic control device 1 includes a hydraulic circuit body 10, an electromagnetic valve 20, and a control unit 30. The hydraulic control device 1 in this figure is an excerpt of a part of the hydraulic circuit body 10.

油圧回路体１０とは、所謂バルブボディと称されるもののことである。この油圧回路体１０は、本体１１の内部に自動変速機（図示略）の作動油を流動させる油圧回路１２が形成されたものである（図３から図５）。油圧回路１２は、自動変速機のポンプ側と制御機構（例えばブレーキやクラッチ）側との間における作動油の流動経路を成す主流路と（図示略）、主流路の経路上で主流路に連通させた流量調整路１２ａと、を備える。   The hydraulic circuit body 10 is a so-called valve body. The hydraulic circuit body 10 is formed by forming a hydraulic circuit 12 for flowing hydraulic oil of an automatic transmission (not shown) inside a main body 11 (FIGS. 3 to 5). The hydraulic circuit 12 communicates with the main flow path on the main flow path (not shown) that forms a flow path of hydraulic oil between the pump side of the automatic transmission and the control mechanism (for example, brake or clutch) side. A flow rate adjusting path 12a.

主流路は、ポンプ側から圧送されてきた作動油の流入口と、制御機構側に作動油を吐出させる吐出口と、を繋いでいる。この主流路には、自動変速機の変速段に応じた様々な流動経路が設けられている。流量調整路１２ａは、後述する電磁弁２０の弁体２２が往復動する円柱状の通路であり、弁体２２毎に設けられている。その弁体２２は、流量調整路１２ａでの位置に応じて主流路における作動油の流量を調整する。   The main flow path connects the inlet of the hydraulic oil pumped from the pump side and the discharge port for discharging the hydraulic oil to the control mechanism side. The main flow path is provided with various flow paths corresponding to the shift stage of the automatic transmission. The flow rate adjusting path 12 a is a cylindrical passage in which a valve body 22 of an electromagnetic valve 20 described later reciprocates, and is provided for each valve body 22. The valve body 22 adjusts the flow rate of the hydraulic oil in the main flow path according to the position in the flow rate adjustment path 12a.

この油圧回路体１０には、油圧回路１２と外部とを連通させる円柱状の収容空間１３が設けられている。その収容空間１３は、流量調整路１２ａと同心上に配置され、この流量調整路１２ａに連通させている。この収容空間１３は、後述する電磁弁２０の収容体２３が収容される空間であり、流量調整路１２ａよりも大きな外径から成る。このため、この油圧回路体１０には、収容空間１３の底部１３ａが環状に形成される（図４及び図５）。その底部１３ａには、収容体２３が収容された際に収容体２３の環状の先端面２３ａ（図６及び図７）が当接する。   The hydraulic circuit body 10 is provided with a cylindrical accommodation space 13 that allows the hydraulic circuit 12 to communicate with the outside. The accommodation space 13 is disposed concentrically with the flow rate adjustment path 12a and communicates with the flow rate adjustment path 12a. The housing space 13 is a space in which a housing body 23 of an electromagnetic valve 20 described later is housed, and has an outer diameter larger than that of the flow rate adjustment path 12a. Therefore, the bottom portion 13a of the accommodation space 13 is formed in an annular shape in the hydraulic circuit body 10 (FIGS. 4 and 5). When the housing body 23 is housed, the annular front end surface 23a (FIGS. 6 and 7) of the housing body 23 comes into contact with the bottom portion 13a.

電磁弁２０は、コイルやリターンスプリング等の駆動機構が内部に収容されている本体２１と、その駆動機構によって軸線方向に往復動する弁体２２と、を備える（図３、図６及び図７）。図中の弁体２２は、便宜上、円柱状にしているが、その形状は問わない。例えば、弁体２２は、油圧回路１２の形態に応じて用意されるものであり、外径の異なる円柱が同心上で組み合わされたスプール状のもの（所謂スプール弁）であってもよい。弁体２２は、流量調整路１２ａに対して同心上に配置され、その中心軸に沿って流量調整路１２ａの中で往復動を行う。   The electromagnetic valve 20 includes a main body 21 in which a drive mechanism such as a coil and a return spring is housed, and a valve body 22 that reciprocates in the axial direction by the drive mechanism (FIGS. 3, 6, and 7). ). Although the valve body 22 in the figure has a cylindrical shape for convenience, the shape is not limited. For example, the valve body 22 is prepared according to the form of the hydraulic circuit 12, and may be a spool-like member (so-called spool valve) in which cylinders having different outer diameters are concentrically combined. The valve body 22 is disposed concentrically with the flow rate adjusting path 12a, and reciprocates in the flow rate adjusting path 12a along the central axis thereof.

この電磁弁２０には、その弁体２２と同心上に配置された円筒状又は円環状の収容体２３が設けられている。その収容体２３は、油圧回路体１０の収容空間１３に対して、中心軸の軸線方向に沿って挿入され且つ収容される。電磁弁２０は、その収容された状態で油圧回路体１０に接続される。この電磁弁２０においては、収容体２３が本体２１に連接されており、この収容体２３から往復動自在に弁体２２を突出させている。この例示の収容体２３としては、互いに外径の異なる同心の第１及び第２の収容体２３Ａ，２３Ｂが設けられている（図６及び図７）。尚、第１収容体２３Ａは、図中において２つの外径の異なる円筒状体又は円環状体を備えているが、説明の便宜上、１つの円筒状体又は円環状体であるものとする。第２収容体２３Ｂは、第１収容体２３Ａに対して、外径が大きく、かつ、本体２１側に配置されている。   The electromagnetic valve 20 is provided with a cylindrical or annular container 23 concentrically arranged with the valve body 22. The accommodating body 23 is inserted and accommodated in the accommodating space 13 of the hydraulic circuit body 10 along the axial direction of the central axis. The electromagnetic valve 20 is connected to the hydraulic circuit body 10 in the accommodated state. In this electromagnetic valve 20, a housing body 23 is connected to a main body 21, and a valve body 22 is protruded from the housing body 23 so as to be able to reciprocate. As the illustrated container 23, concentric first and second containers 23A and 23B having different outer diameters are provided (FIGS. 6 and 7). The first container 23A includes two cylindrical bodies or annular bodies having different outer diameters in the figure, but is assumed to be one cylindrical body or annular body for convenience of explanation. The second container 23B has a larger outer diameter than the first container 23A and is disposed on the main body 21 side.

更に、この電磁弁２０には、その駆動機構に対して電気的に接続された端子２４が設けられている。その端子２４は、弾発力を持たせるべく、金属等の導電性材料から成る板状の母材を折り曲げ加工したものであり、後述する弁側接点２４ａに荷重が加えられた際に撓みを発生させる。   Further, the electromagnetic valve 20 is provided with a terminal 24 electrically connected to the drive mechanism. The terminal 24 is formed by bending a plate-shaped base material made of a conductive material such as metal so as to have elasticity, and is bent when a load is applied to a valve side contact 24a described later. generate.

制御ユニット３０は、この油圧制御装置１の制御動作を担っている制御部（所謂ＥＣＵ：Electronic Control Unit）であり、電磁弁２０を駆動制御することによって、油圧回路１２における作動油の流量を制御する。この制御ユニット３０は、自動変速機の目標変速段に応じて制御対象の電磁弁２０に指令を送り、その電磁弁２０を開弁側又は閉弁側に駆動制御する。   The control unit 30 is a control unit (so-called ECU: Electronic Control Unit) responsible for the control operation of the hydraulic control device 1, and controls the flow rate of the hydraulic oil in the hydraulic circuit 12 by driving and controlling the electromagnetic valve 20. To do. The control unit 30 sends a command to the electromagnetic valve 20 to be controlled in accordance with the target gear position of the automatic transmission, and drives and controls the electromagnetic valve 20 to the valve opening side or the valve closing side.

油圧制御装置１には、その電磁弁２０と制御ユニット３０とを互いに電気的に接続させる導電部材４０が設けられている（図２及び図８）。その導電部材４０は、電磁弁２０に対して電気的に接続させる端子（以下、「弁用端子」という。）としての機能と、制御ユニット３０に対して電気的に接続させる端子（以下、「ＥＣＵ用端子」という。）としての機能と、を有するものである。この導電部材４０においては、電磁弁２０毎に弁用端子とＥＣＵ用端子の組み合わせが設けられている。弁用端子とＥＣＵ用端子は、その組み合わせ毎に電気的に接続されている。例えば、この導電部材４０は、絶縁性フィルムに対して薄膜の導電性材料が設けられたフレキシブルプリント回路基板（ＦＰＣ：Flexible printed circuits）や、金属等の導電性材料から成る板状のバスバなどとして形成される。ここでは、フレキシブルプリント回路基板として形成した導電部材４０を例に挙げている。この導電部材４０には、電磁弁２０に対して電気的に接続させる弁用端子の接点（以下、「弁用接点」という。）４１（図８及び図９）と、図示しないが、制御ユニット３０に対して電気的に接続させるＥＣＵ用端子の接点（ＥＣＵ用接点）と、が設けられている。また、電磁弁２０には、その弁用接点４１に当接させることで、この弁用接点４１に対して電磁弁２０の駆動機構を電気的に接続させる接点（以下、「弁側接点」という。）２４ａが設けられている（図６及び図７）。その弁側接点２４ａは、電磁弁２０の端子２４に突出させて設けたものである。   The hydraulic control device 1 is provided with a conductive member 40 that electrically connects the electromagnetic valve 20 and the control unit 30 to each other (FIGS. 2 and 8). The conductive member 40 functions as a terminal (hereinafter referred to as “valve terminal”) that is electrically connected to the electromagnetic valve 20 and a terminal (hereinafter referred to as “terminal”) that is electrically connected to the control unit 30. And a function as an “ECU terminal”). In this conductive member 40, a combination of a valve terminal and an ECU terminal is provided for each electromagnetic valve 20. The valve terminal and the ECU terminal are electrically connected for each combination. For example, the conductive member 40 may be a flexible printed circuit board (FPC) in which a thin conductive material is provided on an insulating film, or a plate-like bus bar made of a conductive material such as metal. It is formed. Here, a conductive member 40 formed as a flexible printed circuit board is taken as an example. The conductive member 40 has a valve terminal contact (hereinafter referred to as “valve contact”) 41 (FIGS. 8 and 9) to be electrically connected to the electromagnetic valve 20, and a control unit (not shown). And a contact of an ECU terminal (ECU contact) to be electrically connected to 30. The electromagnetic valve 20 is brought into contact with the valve contact 41 to electrically connect the drive mechanism of the electromagnetic valve 20 to the valve contact 41 (hereinafter referred to as “valve contact”). .) 24a is provided (FIGS. 6 and 7). The valve-side contact 24 a is provided so as to protrude from the terminal 24 of the electromagnetic valve 20.

この油圧制御装置１には、電磁弁２０を油圧回路体１０に対して設計通りの所期の状態で接続させ続けるための接続構造を設けている。この油圧制御装置１では、その接続構造の一部を担うものであり、電磁弁２０の収容体２３が接続される接続体５０を備えている（図１から図３）。その接続体５０は、油圧回路体１０に対する相対移動が禁止されるように配置する。例えば、この接続体５０は、ボルト等の固定具（図示略）を介して油圧回路体１０に固定する。この接続体５０は、電磁弁２０と油圧回路体１０との間に介在させたものであり、電磁弁２０の収容体２３が油圧回路体１０の収容空間１３に収容されているときに、この収容体２３を接続する。尚、接続体５０は、そのような固定具を用いずとも、電磁弁２０の油圧回路体１０への接続の完了に伴い油圧回路体１０と電磁弁２０とで挟持させることによって、油圧回路体１０に対する相対移動が禁止されるように構成してもよい。   The hydraulic control device 1 is provided with a connection structure for keeping the electromagnetic valve 20 connected to the hydraulic circuit body 10 in an intended state as designed. The hydraulic control apparatus 1 bears a part of the connection structure, and includes a connection body 50 to which the housing body 23 of the electromagnetic valve 20 is connected (FIGS. 1 to 3). The connection body 50 is arranged so that relative movement with respect to the hydraulic circuit body 10 is prohibited. For example, the connection body 50 is fixed to the hydraulic circuit body 10 via a fixture (not shown) such as a bolt. The connecting body 50 is interposed between the solenoid valve 20 and the hydraulic circuit body 10, and when the housing body 23 of the solenoid valve 20 is housed in the housing space 13 of the hydraulic circuit body 10, The container 23 is connected. In addition, the connection body 50 is clamped by the hydraulic circuit body 10 and the electromagnetic valve 20 when the connection of the electromagnetic valve 20 to the hydraulic circuit body 10 is completed without using such a fixture, so that the hydraulic circuit body The relative movement with respect to 10 may be prohibited.

この接続体５０は、油圧回路体１０の外壁側に取り付けられるものであり、収容空間１３に重ね合わされ、かつ、収容体２３が挿通される貫通孔５１を有する（図３）。電磁弁２０の収容体２３は、その貫通孔５１を介して収容空間１３に挿入される。後で説明するように、この例示の収容体２３には、第１被接続具６１と第３被接続具８１とが径方向の外側へと突出させて設けられている。このため、その貫通孔５１は、収容体２３を挿通させる際に第１被接続具６１と第３被接続具８１とが引っ掛からないように、その第１被接続具６１と第３被接続具８１とを避けた形状に形成する。例えば、その形状を本例示で決める際には、最も突出している第３被接続具８１の形状に合わせて、この第３被接続具８１の挿通が可能な挿通部５１ａを貫通孔５１に設ける（図２）。その挿通部５１ａは、例えば、挿通方向に見た第３被接続具８１の形状と同等の形状であるが、その挿通方向に見た第３被接続具８１の投影面積よりも大きく形成することで、収容体２３の挿通を案内するための誘い部を兼ねさせてもよい。   This connection body 50 is attached to the outer wall side of the hydraulic circuit body 10, and has a through hole 51 that is superimposed on the accommodation space 13 and through which the accommodation body 23 is inserted (FIG. 3). The accommodating body 23 of the electromagnetic valve 20 is inserted into the accommodating space 13 through the through hole 51. As will be described later, a first connected tool 61 and a third connected tool 81 are provided in the illustrated container 23 so as to protrude outward in the radial direction. For this reason, the through-hole 51 is arranged so that the first connected tool 61 and the third connected tool 81 are not caught by the first connected tool 61 and the third connected tool 81 when the container 23 is inserted. 81. For example, when the shape is determined in this example, the through hole 51 is provided with an insertion portion 51a through which the third connected tool 81 can be inserted in accordance with the shape of the third protruding tool 81 that protrudes most. (FIG. 2). The insertion portion 51a has, for example, a shape equivalent to the shape of the third connected tool 81 viewed in the inserting direction, but is formed to be larger than the projected area of the third connected tool 81 viewed in the inserted direction. Thus, it may also serve as an invitation part for guiding the insertion of the container 23.

ところで、この接続体５０は、電磁弁２０と油圧回路体１０とを物理的に接続させる機能のみの部品として設けてもよく、更に他の機能を持たせたものとして設けてもよい。前者の場合の接続体５０は、電磁弁２０毎に個別に配設してもよく、複数の電磁弁２０に対応させた複数の貫通孔５１を有するものとして設けてもよい。そして、この場合の接続体５０は、油圧回路体１０に一体成形されたものとして設けてもよい。一方、後者の場合の接続体５０は、例えば、複数の電磁弁２０に対応させた複数の貫通孔５１を有する主体部分を成形し、この主体部分に導電部材４０を保持させることで、電磁弁２０と油圧回路体１０との間の物理的な接続機能の他に、電磁弁２０と制御ユニット３０との間の電気的な接続機能を持たせてもよい。本実施形態の接続体５０は、この後者を例示している。   By the way, this connection body 50 may be provided as a component having only a function of physically connecting the solenoid valve 20 and the hydraulic circuit body 10, or may be provided as having another function. The connection body 50 in the former case may be provided individually for each electromagnetic valve 20 or may be provided as having a plurality of through holes 51 corresponding to the plurality of electromagnetic valves 20. In this case, the connection body 50 may be provided as an integral part of the hydraulic circuit body 10. On the other hand, the connection body 50 in the latter case is formed by forming a main part having a plurality of through holes 51 corresponding to the plurality of electromagnetic valves 20 and holding the conductive member 40 in the main part, for example, In addition to the physical connection function between the hydraulic valve body 10 and the hydraulic circuit body 10, an electrical connection function between the electromagnetic valve 20 and the control unit 30 may be provided. The connection body 50 of this embodiment illustrates this latter.

本実施形態の接続体５０は、第１接続体５０Ａと第２接続体５０Ｂとを備えており（図１から図３）、主体部分となる第１接続体５０Ａに電磁弁２０と油圧回路体１０の接続機能を持たせる。更に、この接続体５０においては、第１接続体５０Ａと第２接続体５０Ｂとで導電部材４０を保持させる。このため、第１接続体５０Ａと第２接続体５０Ｂは、合成樹脂材料等の絶縁性材料で成形する。第１接続体５０Ａには、導電部材４０における弁用接点４１側を保持する保持部（以下、「第１保持部」という。）が設けられている。第２接続体５０Ｂには、導電部材４０におけるＥＣＵ用接点側を保持する保持部（以下、「第２保持部」という。）が設けられている。第１接続体５０Ａは、板状の基部５０Ａ１と板状の主部５０Ａ２とを重ね合わせて一体化したものであり、その基部５０Ａ１と主部５０Ａ２との間に導電部材４０の弁用接点４１側を挟み込んで保持する。この第１接続体５０Ａにおいては、その基部５０Ａ１と主部５０Ａ２のそれぞれの貫通孔によって前述した貫通孔５１が形成されており、その貫通孔５１に弁用接点４１を露出させている（図８及び図９）。第２接続体５０Ｂは、板状の基部５０Ｂ１と板状の主部５０Ｂ２とを重ね合わせて一体化したものであり、その基部５０Ｂ１と主部５０Ｂ２との間に導電部材４０のＥＣＵ用接点側を挟み込んで保持する。 The connection body 50 of the present embodiment includes a first connection body 50A and a second connection body 50B (FIGS. 1 to 3), and the electromagnetic valve 20 and the hydraulic circuit body are added to the first connection body 50A which is a main part. 10 connection functions are provided. Furthermore, in this connection body 50, the conductive member 40 is held by the first connection body 50A and the second connection body 50B. For this reason, the first connecting body 50A and the second connecting body 50B are formed of an insulating material such as a synthetic resin material. 50 A of 1st connection bodies are provided with the holding | maintenance part (henceforth a "1st holding | maintenance part") holding the contact point 41 for valves in the electrically-conductive member 40. As shown in FIG. The second connecting body 50B is provided with a holding portion (hereinafter referred to as “second holding portion”) that holds the ECU contact side of the conductive member 40. The first connection member 50A is obtained by integrating by superposing a main portion 50A 2 of the plate-like base portion 50A 1 and the plate, the conductive member 40 between its base 50A 1 and the main portion 50A 2 The valve contact 41 side is sandwiched and held. In the first connection member 50A, and its base 50A 1 and a through hole 51 as described above by each of the through holes of the main portion 50A 2 is formed, to expose the valve contacts 41 into the through-hole 51 ( 8 and 9). The second connecting member 50B is obtained by integrating by superposing a main portion 50B 2 of the plate-shaped base portion 50B 1 and the plate, the conductive member 40 between its base 50B 1 and the main portion 50B 2 The ECU contact side is sandwiched and held.

ここで、この油圧制御装置１においては、油圧回路体１０と電磁弁２０の接続完了後に、油圧回路体１０と電磁弁２０の弁側接点２４ａとで導電部材４０の弁用接点４１を挟持させる（図１０）。そして、その弁側接点２４ａと弁用接点４１とは、電磁弁２０の回動動作の停止時に当接するように（つまり油圧回路体１０に対する電磁弁２０の接続が完了したときに電気的に接続されるように）配置する。これにより、この油圧制御装置１においては、電磁弁２０と導電部材４０との間の電気的な接続作業を別途行う必要が無い。また、この油圧制御装置１においては、その回動動作と共に弁側接点２４ａが弁用接点４１に沿って摺動し、弁側接点２４ａと弁用接点４１との間の接触部分にワイピング作用を生じさせることができるので、その接触部分に形成されている酸化皮膜の除去が可能になる。そして、この油圧制御装置１では、その接触部分が流量調整路１２ａとは逆側に配置されているので、除去された酸化皮膜の流量調整路１２ａへの侵入を抑えることができ、作動油内でのコンタミネーションの発生を抑えることができる。尚、本図では、図示の便宜上、油圧回路体１０と電磁弁２０の内部形状を省いている。   Here, in the hydraulic control device 1, after the connection between the hydraulic circuit body 10 and the electromagnetic valve 20 is completed, the valve contact 41 of the conductive member 40 is held between the hydraulic circuit body 10 and the valve-side contact 24 a of the electromagnetic valve 20. (FIG. 10). The valve-side contact 24a and the valve contact 41 are brought into contact with each other when the rotation of the electromagnetic valve 20 is stopped (that is, electrically connected when the connection of the electromagnetic valve 20 to the hydraulic circuit body 10 is completed). Place). Thereby, in this hydraulic control apparatus 1, it is not necessary to perform the electrical connection work between the solenoid valve 20 and the conductive member 40 separately. Further, in the hydraulic control device 1, the valve side contact 24a slides along the valve contact 41 along with the turning operation, and a wiping action is applied to the contact portion between the valve side contact 24a and the valve contact 41. Therefore, the oxide film formed on the contact portion can be removed. In the hydraulic control device 1, the contact portion is disposed on the side opposite to the flow rate adjustment path 12a, so that it is possible to prevent the removed oxide film from entering the flow rate adjustment path 12a. It is possible to suppress the occurrence of contamination in In the drawing, the internal shapes of the hydraulic circuit body 10 and the electromagnetic valve 20 are omitted for convenience of illustration.

このように、この油圧制御装置１において、導電部材４０と接続体５０の一体物は、電磁弁２０と制御ユニット３０とを互いに電気的に接続させるコネクタモジュールとして機能する。ここで、この例示の第２接続体５０Ｂにおいては、主部５０Ｂ２に、制御ユニット３０を保持するＥＣＵ保持部５２が設けられている（図１及び図２）。このため、この油圧制御装置１においては、制御ユニット３０と導電部材４０を接続体５０に接続して一体化させ、これにより成る一体物をモジュール化してもよい。 Thus, in this hydraulic control apparatus 1, the integrated body of the conductive member 40 and the connection body 50 functions as a connector module that electrically connects the electromagnetic valve 20 and the control unit 30 to each other. Here, in the second connecting member 50B of this example, the main portion 50B 2, ECU holding unit 52 for holding the control unit 30 is provided (FIGS. 1 and 2). For this reason, in the hydraulic control apparatus 1, the control unit 30 and the conductive member 40 may be connected to the connection body 50 and integrated, and the integrated unit formed thereby may be modularized.

電磁弁２０の接続構造は、第１接続構造体６０と、第２接続構造体７０と、その接続体５０を利用した第３接続構造体８０と、を備える（図３）。これら第１から第３の接続構造体６０，７０，８０は、それぞれ１つずつ設けられていればよい。本実施形態では、後述するように、第１接続構造体６０と第３接続構造体８０を２箇所ずつに設けると共に、第２接続構造体７０を１箇所に設ける。   The connection structure of the solenoid valve 20 includes a first connection structure 60, a second connection structure 70, and a third connection structure 80 using the connection body 50 (FIG. 3). Each of the first to third connection structures 60, 70, 80 only needs to be provided one by one. In the present embodiment, as will be described later, the first connection structure 60 and the third connection structure 80 are provided in two places, and the second connection structure 70 is provided in one place.

第１接続構造体６０は、電磁弁２０の収容体２３が油圧回路体１０の収容空間１３に収容されているときに、これらの軸線方向における油圧回路体１０と電磁弁２０との間の相対移動を禁止させるものである。   The first connection structure 60 has a relative relationship between the hydraulic circuit body 10 and the solenoid valve 20 in the axial direction when the housing body 23 of the solenoid valve 20 is housed in the housing space 13 of the hydraulic circuit body 10. The movement is prohibited.

この第１接続構造体６０は、収容空間１３を成す壁部（内周壁部１３ｂ）及び収容体２３の内の一方に設けた第１被接続具６１（図６及び図７）と、その内の他方に設け、収容体２３が収容空間１３に収容されているときに第１被接続具６１を軸線方向（収容空間１３や収容体２３の軸線方向）で係止する第１接続具６２（図４及び図５）と、を備える。   The first connection structure 60 includes a first connected device 61 (FIGS. 6 and 7) provided on one of the wall portion (inner peripheral wall portion 13b) forming the housing space 13 and the housing body 23, The first connector 62 (which is provided on the other side of the first connector 62 and locks the first connected device 61 in the axial direction (the axial direction of the storage space 13 and the storage body 23) when the storage body 23 is stored in the storage space 13. 4 and 5).

具体的に、第１被接続具６１は、収容空間１３を成す壁部及び収容体２３の内の一方から突出させた突出部である。第１被接続具６１は、収容空間１３に設ける場合、例えば、収容空間１３の壁部（内周壁部１３ｂ）から径方向の内側に向けて部分的に突出させる。これに対して、収容体２３に設ける場合、第１被接続具６１は、例えば、収容体２３の外周壁部から径方向の外側に向けて部分的に突出させる。   Specifically, the first connected tool 61 is a protruding portion that protrudes from one of the wall portion that forms the accommodating space 13 and the accommodating body 23. When the first connected device 61 is provided in the accommodation space 13, for example, the first connection tool 61 partially protrudes radially inward from the wall portion (inner peripheral wall portion 13 b) of the accommodation space 13. On the other hand, when providing in the accommodating body 23, the 1st to-be-connected tool 61 is made to protrude partially toward the outer side of radial direction from the outer peripheral wall part of the accommodating body 23, for example.

ここで、電磁弁２０は、油圧回路体１０に取り付ける際に、中心軸（収容体２３の中心軸）の軸線方向に沿って収容体２３を収容空間１３に挿入し、収容体２３の先端面２３ａが収容空間１３の底部１３ａに当接した後、その中心軸の軸周りに全体を回転させる。このため、第１接続具６２は、収容体２３の収容空間１３への収容動作に応じて第１被接続具６１を案内し、収容体２３の収容動作における中心軸（収容体２３の中心軸）の軸周りの回動動作の後に第１被接続具６１を軸線方向（収容空間１３や収容体２３の軸線方向）で係止する溝部として形成する。第１接続具６２は、収容空間１３に設ける場合、例えば、収容空間１３の壁部（内周壁部１３ｂ）の一部を径方向の外側に凹ませた溝形状に形成する。これに対して、収容体２３に設ける場合、第１接続具６２は、例えば、収容体２３の外周壁部の一部を径方向の内側に凹ませた溝形状に形成する。   Here, when the electromagnetic valve 20 is attached to the hydraulic circuit body 10, the housing body 23 is inserted into the housing space 13 along the axial direction of the central axis (the central axis of the housing body 23), and the distal end surface of the housing body 23 is inserted. After 23 a abuts against the bottom 13 a of the accommodation space 13, the whole is rotated around the central axis. For this reason, the 1st connection tool 62 guides the 1st to-be-connected tool 61 according to the accommodation operation to the accommodation space 13 of the container 23, and the center axis | shaft in the accommodation operation | movement of the container 23 (center axis of the container 23) The first connecting tool 61 is formed as a groove portion that is locked in the axial direction (the axial direction of the housing space 13 or the housing body 23) after the pivoting movement around the axis. When the first connector 62 is provided in the accommodation space 13, for example, it is formed in a groove shape in which a part of the wall portion (inner peripheral wall portion 13 b) of the accommodation space 13 is recessed outward in the radial direction. On the other hand, when providing in the container 23, the 1st connection tool 62 is formed in the groove | channel shape which dented a part of outer peripheral wall part of the container 23 in the radial inside, for example.

この第１接続具６２は、具体的に、軸線方向溝部６２Ａを有する。その軸線方向溝部６２Ａは、収容体２３を収容空間１３へと軸線方向に沿って挿入する際に、第１被接続具６１を案内する溝である。この軸線方向溝部６２Ａは、油圧回路体１０の外壁面から収容空間１３の底部１３ａの位置まで軸線方向に沿って延在させている。その軸線方向溝部６２Ａは、例えば、挿入方向に見た第１被接続具６１の形状と同等の形状であるが、その挿入方向に見た第１被接続具６１の投影面積よりも周方向に大きく形成することで、収容体２３の収容空間１３への挿入を案内するための誘い部も兼ねている。また、この第１接続具６２は、周方向溝部６２Ｂを有する。その周方向溝部６２Ｂは、収容体２３を収容空間１３の中で中心軸の軸周りに回転させる際に、第１被接続具６１を案内する溝である。この周方向溝部６２Ｂは、軸線方向溝部６２Ａの底部１３ａ側から周方向に延在させている。この周方向溝部６２Ｂは、その底部１３ａと同一平面上の第１側壁６２Ｂ１と、この第１側壁６２Ｂ１に対して軸線方向で対向している第２側壁６２Ｂ２と、を有している（図１１）。尚、本図では、図示の便宜上、油圧回路体１０と電磁弁２０の内部形状を省いている。 Specifically, the first connector 62 has an axial groove 62A. The axial direction groove portion 62 </ b> A is a groove that guides the first connected tool 61 when the accommodating body 23 is inserted into the accommodating space 13 along the axial direction. The axial groove 62A extends along the axial direction from the outer wall surface of the hydraulic circuit body 10 to the position of the bottom 13a of the accommodation space 13. The axial groove 62A has, for example, a shape equivalent to the shape of the first connected tool 61 viewed in the insertion direction, but in the circumferential direction with respect to the projected area of the first connected tool 61 viewed in the insertion direction. By forming it large, it also serves as an invitation part for guiding insertion of the container 23 into the storage space 13. Further, the first connector 62 has a circumferential groove 62B. The circumferential groove 62 </ b> B is a groove that guides the first connected tool 61 when the container 23 is rotated around the central axis in the housing space 13. The circumferential groove 62B extends in the circumferential direction from the bottom 13a side of the axial groove 62A. The circumferential groove portion 62B includes a first side wall 62B 1 on the bottom portion 13a flush, a second side wall 62B 2 which are opposed to each other in the axial direction with respect to the first side wall 62B 1, the (FIG. 11). In the drawing, the internal shapes of the hydraulic circuit body 10 and the electromagnetic valve 20 are omitted for convenience of illustration.

その第１側壁６２Ｂ１と第２側壁６２Ｂ２との間隔は、電磁弁２０の回動動作を阻害しない範囲内で、第１被接続具６１の軸線方向における長さと略同等の大きさに形成することが望ましい。これにより、第１被接続具６１は、この第１側壁６２Ｂ１と第２側壁６２Ｂ２とによって軸線方向の動きが規制される。この油圧制御装置１においては、第１接続構造体６０を少なくとも１箇所に設けることによって、軸線方向における油圧回路体１０と電磁弁２０との間の相対移動を禁止することができる。また、この第１接続構造体６０は、少なくとも２箇所に設けることで、その相対移動の禁止の効果を高めることができる。例えば、この例示では、その軸線の周り（中心軸の軸周り）で略等間隔に第１接続構造体６０を２箇所設けている。よって、この油圧制御装置１においては、油圧回路体１０と電磁弁２０との間の軸線方向の動きが均等に規制されるので、より適切に軸線方向における油圧回路体１０と電磁弁２０との間の相対移動を禁止することができる。 A first side wall 62B 1 and the distance between the second side wall 62B 2, within a range that does not inhibit the rotation of the solenoid valve 20, formed to a length and substantially equal magnitude in the axial direction of the first object connector 61 It is desirable to do. Thus, first the connector 61, the movement in the axial direction is restricted by the first side wall 62B 1 and the second side wall 62B 2. In the hydraulic control apparatus 1, the relative movement between the hydraulic circuit body 10 and the electromagnetic valve 20 in the axial direction can be prohibited by providing the first connection structure 60 at at least one location. Moreover, the effect of prohibiting the relative movement can be enhanced by providing the first connection structure 60 in at least two places. For example, in this example, two first connection structures 60 are provided at approximately equal intervals around the axis (around the center axis). Therefore, in this hydraulic control device 1, since the movement in the axial direction between the hydraulic circuit body 10 and the electromagnetic valve 20 is evenly regulated, the hydraulic circuit body 10 and the electromagnetic valve 20 in the axial direction more appropriately. Relative movement between them can be prohibited.

次に、第２接続構造体７０は、電磁弁２０の収容体２３が油圧回路体１０の収容空間１３に収容されているときに、これらの軸線方向に対する直交平面に沿った油圧回路体１０と電磁弁２０との間の相対移動を禁止させるものである。その禁止対象となる相対移動とは、その軸線方向に対する直交方向への相対移動のことである。   Next, when the container 23 of the electromagnetic valve 20 is housed in the housing space 13 of the hydraulic circuit body 10, the second connection structure 70 includes the hydraulic circuit body 10 along the plane orthogonal to the axial direction. Relative movement with the solenoid valve 20 is prohibited. The relative movement to be prohibited is relative movement in the direction orthogonal to the axial direction.

この第２接続構造体７０は、収容空間１３を成す壁部（内周壁部１３ｂ）及び収容体２３の内の一方に設けた第２被接続具７１（図３、図６及び図７）と、その内の他方に設け、収容体２３が収容空間１３に収容されているときに第２被接続具７１の軸線方向（収容空間１３や収容体２３の軸線方向）に対する直交平面に沿った相対移動を禁止する第２接続具７２（図３から図５）と、を備える。   The second connection structure 70 includes a wall portion (inner peripheral wall portion 13 b) forming the accommodation space 13 and a second connected tool 71 (FIG. 3, FIG. 6 and FIG. 7) provided on one of the accommodation bodies 23. , Provided on the other of them, when the container 23 is housed in the housing space 13, relative to the direction perpendicular to the axial direction of the second connected tool 71 (the axial direction of the housing space 13 or the housing body 23). And a second connector 72 (FIGS. 3 to 5) that prohibits movement.

例えば、この例示では、第１収容体２３Ａの外周壁部２３ｂを第２被接続具７１として利用し、かつ、収容空間１３の内周壁部１３ｂを第２接続具７２として利用する。この場合の第２接続構造体７０においては、その外周壁部２３ｂ（第２被接続具７１）と内周壁部１３ｂ（第２接続具７２）とを同等の外径に形成し、これらをガタが抑えられた状態で嵌合させることによって、収容体２３と収容空間１３との間における軸線方向に対しての直交方向への相対移動を禁止させる。これにより、この第２接続構造体７０は、油圧回路体１０と電磁弁２０との間における軸線方向に対しての直交方向への相対移動を禁止することができる。   For example, in this illustration, the outer peripheral wall portion 23 b of the first container 23 </ b> A is used as the second connected tool 71, and the inner peripheral wall portion 13 b of the storage space 13 is used as the second connecting tool 72. In the second connection structure 70 in this case, the outer peripheral wall portion 23b (second connected tool 71) and the inner peripheral wall portion 13b (second connecting tool 72) are formed to have the same outer diameter, and these are loosely formed. By fitting in a state where the pressure is suppressed, relative movement in the direction orthogonal to the axial direction between the housing 23 and the housing space 13 is prohibited. Thereby, this 2nd connection structure 70 can prohibit the relative movement to the orthogonal | vertical direction with respect to the axial direction between the hydraulic circuit body 10 and the solenoid valve 20. FIG.

ここで、この油圧制御装置１においては、第１接続構造体６０が軸線の周り（中心軸の軸周り）で略等間隔に複数配置されているので、第１被接続具６１に第２被接続具７１の機能を持たせ、かつ、第１接続具６２に第２接続具７２の機能を持たせるように構成してもよい。この場合には、少なくとも２組の第１被接続具６１と第１接続具６２の組み合わせを径方向（収容空間１３や収容体２３の径方向）に対向させて配置し、かつ、第１被接続具６１と第１接続具６２とをガタが抑えられた状態で嵌合されるように形成することによって、収容体２３と収容空間１３との間における軸線方向に対しての直交方向への相対移動を禁止させる。   Here, in the hydraulic control apparatus 1, a plurality of the first connection structures 60 are arranged at substantially equal intervals around the axis (around the central axis), so that the second connection target 60 is connected to the first connection target 61. The function of the connection tool 71 may be provided, and the first connection tool 62 may be configured to have the function of the second connection tool 72. In this case, the combination of at least two sets of the first connected device 61 and the first connected device 62 is arranged to face each other in the radial direction (the radial direction of the storage space 13 and the storage body 23), and the first connected device By forming the connecting tool 61 and the first connecting tool 62 so as to be fitted in a state in which the backlash is suppressed, the connecting tool 23 and the receiving space 13 are orthogonal to the axial direction between the receiving body 23 and the receiving space 13. Prohibit relative movement.

このような構成を成すべく、第１被接続具６１と第１接続具６２は、例えば、軸線方向でのガタを抑えた嵌合が行えるように形成する。例えば、先に示したように、第１側壁６２Ｂ１と第２側壁６２Ｂ２との間隔は、電磁弁２０の回動動作を阻害しない範囲内で、第１被接続具６１の軸線方向における長さと略同等の大きさに形成する。そして、径方向で対向している２組においては、双方の組み合わせの第１被接続具６１及び第１接続具６２によって、収容体２３と収容空間１３との間における径方向のガタを抑えた嵌合が行えるように形成する。例えば、その２組の第１被接続具６１と第１接続具６２は、第１被接続具６１の径方向外側の壁部６１ａと周方向溝部６２Ｂの径方向外側の壁部（底壁）６２Ｂ３とを、少なくとも接続完了後の位置において、収容体２３の挿入動作と回動動作を阻害しない範囲内で当接させるように形成する（図１１）。つまり、この場合には、その２組の第１被接続具６１の壁部６１ａと周方向溝部６２Ｂの底壁６２Ｂ３とによって、収容空間１３と収容体２３とを互いに径方向で嵌合させることができる。これにより、油圧回路体１０と電磁弁２０との間においては、軸線方向に対しての直交方向への相対移動を禁止することができる。 In order to achieve such a configuration, the first connected tool 61 and the first connecting tool 62 are formed, for example, so as to be able to be fitted with little play in the axial direction. For example, as indicated above, the first side wall 62B 1 and the distance between the second side wall 62B 2, within a range that does not inhibit the rotation of the solenoid valve 20, the length in the axial direction of the first object connector 61 And approximately the same size. In the two sets facing each other in the radial direction, the backlash in the radial direction between the housing body 23 and the housing space 13 is suppressed by the first connected tool 61 and the first connecting tool 62 of both combinations. It is formed so that it can be fitted. For example, the two sets of the first connected device 61 and the first connected device 62 include a radially outer wall portion 61a of the first connected device 61 and a radially outer wall portion (bottom wall) of the circumferential groove portion 62B. and 62B 3, in position after at least connection completion, within a range that does not inhibit the insertion operation and the rotating operation of the container 23 is formed so as to abut (Figure 11). That is, in this case, the wall portion 61a and the circumferential groove portion 62B bottom wall 62B 3 of the first object connector 61 of the two pairs, is fitted and a housing space 13 and housing 23 in radial directions be able to. As a result, relative movement in the direction orthogonal to the axial direction can be prohibited between the hydraulic circuit body 10 and the electromagnetic valve 20.

次に、第３接続構造体８０は、電磁弁２０の収容体２３が油圧回路体１０の収容空間１３に収容されているときに、中心軸（収容空間１３や収容体２３の中心軸）の軸周りに沿った油圧回路体１０と電磁弁２０との間の相対回転を禁止させるものである。   Next, the third connection structure 80 has a central axis (the central axis of the accommodation space 13 and the accommodation body 23) when the accommodation body 23 of the electromagnetic valve 20 is accommodated in the accommodation space 13 of the hydraulic circuit body 10. Relative rotation between the hydraulic circuit body 10 and the solenoid valve 20 along the axis is prohibited.

この第３接続構造体８０は、接続体５０及び収容体２３の内の一方に設けた第３被接続具８１（図６及び図７）と、その内の他方に設け、収容体２３が収容空間１３に収容されているときに第３被接続具８１を係止して、油圧回路体１０に対する電磁弁２０の中心軸の軸周りの相対回転を禁止させる第３接続具８２（図８及び図９）と、を備える。   The third connection structure 80 is provided on one of the connection body 50 and the accommodation body 23, and on the other of them, the third connection tool 81 (FIGS. 6 and 7). The third connector 82 (FIG. 8 and FIG. 8) that locks the third connector 81 when housed in the space 13 and prohibits relative rotation around the central axis of the solenoid valve 20 with respect to the hydraulic circuit body 10. FIG. 9).

具体的に、第３被接続具８１は、接続体５０及び収容体２３の内の一方から突出させた突出部である。第３被接続具８１は、接続体５０に設ける場合、例えば、接続体５０の貫通孔５１を成す壁部（内壁部）から径方向の内側に向けて突出させる。これに対して、収容体２３に設ける場合、第３被接続具８１は、例えば、収容体２３の外周壁部から径方向の外側に向けて突出させる。   Specifically, the third connected tool 81 is a protruding portion that protrudes from one of the connecting body 50 and the housing body 23. When the third connected tool 81 is provided in the connecting body 50, for example, the third connecting tool 81 protrudes radially inward from a wall portion (inner wall portion) forming the through hole 51 of the connecting body 50. On the other hand, when providing in the container 23, the 3rd to-be-connected tool 81 is made to protrude toward the outer side of radial direction from the outer peripheral wall part of the container 23, for example.

一方、第３接続具８２は、先に示した収容体２３の回動動作と共に第３被接続具８１で押動されながら第３被接続具８１を係止して、その回動動作を停止させる係止部である。第３接続具８２は、接続体５０に設ける場合、例えば、貫通孔５１の壁部（内壁部）から径方向の内側に向けて突出させる。これに対して、収容体２３に設ける場合、第３接続具８２は、例えば、収容体２３の外周壁部から径方向の外側に向けて突出させる。この第３接続具８２は、具体的に、収容体２３の回動動作と共に第３被接続具８１が押動しながら乗り越える爪部８２ａと、この爪部８２ａを接続体５０及び収容体２３の内の前記他方に連結させる連結部８２ｂと、を有する。その連結部８２ｂは、第３被接続具８１が爪部８２ａを押動しながら乗り越えた際に第３被接続具８１に対して押圧力を加えるように、柔軟性を持たせて形成することが望ましい。   On the other hand, the third connection tool 82 engages with the third connected tool 81 while being pushed by the third connected tool 81 together with the turning operation of the container 23 described above, and stops the turning operation. It is a latching part to be made. When the third connection tool 82 is provided in the connection body 50, for example, the third connection tool 82 is protruded from the wall portion (inner wall portion) of the through hole 51 toward the inside in the radial direction. On the other hand, when providing in the container 23, the 3rd connection tool 82 is made to protrude toward the outer side of radial direction from the outer peripheral wall part of the container 23, for example. Specifically, the third connection tool 82 includes a claw portion 82a that the third connection tool 81 rides over while the third connection tool 81 is pushed together with the rotation of the container 23, and the connection body 50 and the container 23. And a connecting portion 82b to be connected to the other. The connecting portion 82b is formed with flexibility so that a pressing force is applied to the third connected device 81 when the third connected device 81 moves over the claw portion 82a. Is desirable.

この油圧制御装置１においては、そのような第３接続構造体８０を少なくとも１箇所に設けることによって、収容体２３の接続体５０に対する回動動作（電磁弁２０の油圧回路体１０への組付け作業時における回動動作）とは逆向きの回動動作が規制される。そして、この油圧制御装置１では、先に示したように、接続体５０が油圧回路体１０に固定されている。従って、この油圧制御装置１においては、油圧回路体１０と電磁弁２０との間における軸周りの相対回転を禁止させることができる。ここで、この第３接続構造体８０は、少なくとも２箇所に設けることで、その相対回転の禁止の効果を高めることができる。例えば、この例示では、その軸周りで略等間隔に第３接続構造体８０を２箇所設けている。よって、この油圧制御装置１においては、より適切に油圧回路体１０と電磁弁２０との間における軸周りの相対回転を禁止することができる。   In the hydraulic control apparatus 1, such a third connection structure 80 is provided in at least one place, thereby rotating the container 23 with respect to the connection body 50 (assembly of the electromagnetic valve 20 to the hydraulic circuit body 10). The rotation operation in the opposite direction to the rotation operation during work is restricted. In the hydraulic control apparatus 1, the connection body 50 is fixed to the hydraulic circuit body 10 as described above. Therefore, in the hydraulic control device 1, relative rotation around the axis between the hydraulic circuit body 10 and the electromagnetic valve 20 can be prohibited. Here, the third connection structure 80 can be provided in at least two places, thereby enhancing the effect of prohibiting relative rotation. For example, in this example, two third connection structures 80 are provided at approximately equal intervals around the axis. Therefore, in the hydraulic control device 1, relative rotation around the axis between the hydraulic circuit body 10 and the electromagnetic valve 20 can be prohibited more appropriately.

ここで、それぞれの第３接続構造体８０においては、第３被接続具８１と第３接続具８２との間で径方向に沿った押圧力が加わるように、第３被接続具８１と第３接続具８２とを形成してもよい。これにより、この第３接続構造体８０は、収容体２３と接続体５０との間で中心軸（収容空間１３や収容体２３の中心軸）の軸線方向に対する直交平面に沿った相対的な動きを規制することができる。つまり、このように第３接続構造体８０を構成することによって、この第３接続構造体８０に第２接続構造体７０の機能も持たせることができるので、この油圧制御装置１においては、軸線方向に対する直交平面に沿った油圧回路体１０と電磁弁２０との間の相対移動を禁止することもできる。この第３接続構造体８０における第２接続構造体７０の機能は、先に示した第２接続構造体７０の構成と併用させるが如く設けてもよく、この第２接続構造体７０の構成に替えて設けてもよい。   Here, in each of the third connection structures 80, the third connected device 81 and the third connected device 81 and the third connected device 80 are connected so that a pressing force is applied along the radial direction between the third connected device 81 and the third connected device 82. A three-connector 82 may be formed. Thereby, this 3rd connection structure 80 moves relatively along the orthogonal plane with respect to the axial direction of the central axis (the central axis of the accommodation space 13 or the accommodation body 23) between the accommodation body 23 and the connection body 50. Can be regulated. That is, by configuring the third connection structure 80 in this way, the third connection structure 80 can also have the function of the second connection structure 70. Relative movement between the hydraulic circuit body 10 and the electromagnetic valve 20 along a plane orthogonal to the direction can also be prohibited. The function of the second connection structure 70 in the third connection structure 80 may be provided as used together with the configuration of the second connection structure 70 described above. It may be provided instead.

この例示では、第１収容体２３Ａに第１被接続具６１を設けると共に、収容空間１３の内周壁部１３ｂに第１接続具６２を設けている。そして、この例示では、第２収容体２３Ｂに第３被接続具８１を設けると共に、接続体５０に第３接続具８２を設けている。   In this illustration, the first connector 61 is provided in the first housing 23 </ b> A, and the first connector 62 is provided in the inner peripheral wall portion 13 b of the storage space 13. In this example, the third connector 81 is provided in the second container 23 </ b> B, and the third connector 82 is provided in the connector 50.

この油圧制御装置１において油圧回路体１０と電磁弁２０とを接続する際には、電磁弁２０の収容体２３の油圧回路体１０の収容空間１３への挿入動作に伴って、第１収容体２３Ａから突出されている第１被接続具６１が油圧回路体１０の軸線方向溝部６２Ａに沿って軸線方向へと案内されると共に（図１２）、第２収容体２３Ｂから突出されている第３被接続具８１が接続体５０の貫通孔５１に挿入される（図１３）。この際には、第２接続構造体７０によって、外周壁部２３ｂ（第２被接続具７１）と内周壁部１３ｂ（第２接続具７２）とが嵌合しているので、軸線方向に対する直交平面に沿った油圧回路体１０と電磁弁２０との間の相対移動が禁止されている。一方、この際には、第１接続構造体６０において、第１被接続具６１と第１接続具６２との間の軸線方向に対する相対移動が規制されておらず、かつ、第３接続構造体８０において、第３被接続具８１と第３接続具８２とが係合していない。尚、これらの各図では、図示の便宜上、電磁弁２０の内部形状を省いている。   When the hydraulic circuit body 10 and the solenoid valve 20 are connected in the hydraulic control device 1, the first housing body is moved along with the insertion operation of the housing body 23 of the solenoid valve 20 into the housing space 13 of the hydraulic circuit body 10. The first connected tool 61 protruding from 23A is guided in the axial direction along the axial groove 62A of the hydraulic circuit body 10 (FIG. 12), and the third protruding from the second housing 23B. The tool 81 is inserted into the through hole 51 of the connection body 50 (FIG. 13). At this time, since the outer peripheral wall portion 23b (second connected tool 71) and the inner peripheral wall portion 13b (second connecting tool 72) are fitted by the second connection structure 70, they are orthogonal to the axial direction. Relative movement between the hydraulic circuit body 10 and the electromagnetic valve 20 along the plane is prohibited. On the other hand, in this case, in the first connection structure 60, the relative movement in the axial direction between the first connected device 61 and the first connection device 62 is not restricted, and the third connection structure body. In 80, the third connector 81 and the third connector 82 are not engaged. In these drawings, the internal shape of the solenoid valve 20 is omitted for convenience of illustration.

次に、この油圧制御装置１においては、電磁弁２０を軸周りに回転させる。この油圧制御装置１では、その電磁弁２０の回動動作に伴って、第１被接続具６１が油圧回路体１０の周方向溝部６２Ｂに沿って案内されると共に（図１４）、第３被接続具８１が接続体５０の第３接続具８２の爪部８２ａを乗り越えて、この爪部８２ａで係止される（図１５）。この油圧制御装置１においては、第３被接続具８１の爪部８２ａの乗り越えと共に電磁弁２０の軸周りの回転が止められて、油圧回路体１０と電磁弁２０との間の接続が完了する。第２接続構造体７０においては、電磁弁２０を回転させる前から外周壁部２３ｂ（第２被接続具７１）と内周壁部１３ｂ（第２接続具７２）とが嵌合している。このため、この油圧制御装置１においては、電磁弁２０の接続完了後に、油圧回路体１０と電磁弁２０との間における軸線方向に対する直交平面に沿った相対移動が禁止されている。また、この油圧制御装置１においては、電磁弁２０の接続完了後に、第１被接続具６１と第１接続具６２との間の軸線方向に対する相対移動が規制されるので、油圧回路体１０と電磁弁２０との間における軸線方向に対する相対移動が禁止される。また、この油圧制御装置１においては、電磁弁２０の接続完了後に、第３被接続具８１と第３接続具８２とが係合して、電磁弁２０の接続作業時とは逆向きの回転が規制されるので、油圧回路体１０と電磁弁２０との間における軸周りの相対回転が禁止される。尚、これらの各図では、図示の便宜上、電磁弁２０の内部形状を省いている。   Next, in the hydraulic control apparatus 1, the electromagnetic valve 20 is rotated around the axis. In the hydraulic control device 1, the first connector 61 is guided along the circumferential groove 62 </ b> B of the hydraulic circuit body 10 (FIG. 14) as the electromagnetic valve 20 rotates. The connection tool 81 gets over the claw part 82a of the third connection tool 82 of the connection body 50 and is locked by the claw part 82a (FIG. 15). In the hydraulic control device 1, the rotation around the axis of the electromagnetic valve 20 is stopped while the claw portion 82 a of the third connected device 81 is overcome, and the connection between the hydraulic circuit body 10 and the electromagnetic valve 20 is completed. . In the second connection structure 70, the outer peripheral wall 23b (second connected tool 71) and the inner peripheral wall 13b (second connecting tool 72) are fitted before the electromagnetic valve 20 is rotated. For this reason, in the hydraulic control device 1, after the connection of the electromagnetic valve 20 is completed, relative movement along the plane orthogonal to the axial direction between the hydraulic circuit body 10 and the electromagnetic valve 20 is prohibited. Further, in the hydraulic control device 1, since the relative movement in the axial direction between the first connected tool 61 and the first connecting tool 62 is restricted after the connection of the electromagnetic valve 20 is completed, the hydraulic circuit body 10 Relative movement in the axial direction with respect to the solenoid valve 20 is prohibited. Further, in the hydraulic control device 1, after the connection of the electromagnetic valve 20 is completed, the third connected tool 81 and the third connecting tool 82 are engaged to rotate in the direction opposite to that during the connection work of the electromagnetic valve 20. Therefore, relative rotation around the axis between the hydraulic circuit body 10 and the electromagnetic valve 20 is prohibited. In these drawings, the internal shape of the solenoid valve 20 is omitted for convenience of illustration.

以上示したように、本実施形態における電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）は、液圧回路体（油圧回路体１０）と電磁弁２０との間における軸周りの相対回転以外の相対移動に関して、液圧回路体（油圧回路体１０）と電磁弁２０との間に設けた第１接続構造体６０と第２接続構造体７０とに担わせる一方、軸周りの相対回転に関して、電磁弁２０と接続体５０との間に設けた第３接続構造体８０に担わせている。従って、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）は、液圧回路体（油圧回路体１０）と電磁弁２０との間において、ボルト等の固定具を用いずとも、あらゆる方向での接続完了後の相対移動（相対回転を含む）を禁止させることができる。そして、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）は、走行中に外部から入力荷重が加わったとしても、そのような固定具を必要としない簡便な構成によって、液圧回路体（油圧回路体１０）と電磁弁２０との間の接続強度を所期の状態で維持することができる。このため、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）は、液圧回路体（油圧回路体１０）に対する電磁弁２０の所期の接続状態を簡便な構成で保つことができる。   As described above, the connection structure of the electromagnetic valve 20 and the hydraulic control device (hydraulic control device 1) in the present embodiment are arranged around the axis between the hydraulic circuit body (hydraulic circuit body 10) and the electromagnetic valve 20. With respect to relative movement other than relative rotation, the first connection structure 60 and the second connection structure 70 provided between the hydraulic circuit body (hydraulic circuit body 10) and the electromagnetic valve 20 are caused to bear on the axis. Regarding the relative rotation, the third connection structure 80 provided between the electromagnetic valve 20 and the connection body 50 is used. Therefore, the connection structure of the electromagnetic valve 20 and the hydraulic control device (hydraulic control device 1) do not use a fixing tool such as a bolt between the hydraulic circuit body (hydraulic circuit body 10) and the electromagnetic valve 20. , Relative movement (including relative rotation) after completion of connection in any direction can be prohibited. The connection structure of the electromagnetic valve 20 and the hydraulic pressure control device (hydraulic control device 1) have a simple configuration that does not require such a fixture even when an input load is applied from the outside during traveling. The connection strength between the pressure circuit body (hydraulic circuit body 10) and the solenoid valve 20 can be maintained in an intended state. Therefore, the connection structure of the electromagnetic valve 20 and the hydraulic pressure control device (hydraulic control device 1) keep the desired connection state of the electromagnetic valve 20 with respect to the hydraulic pressure circuit body (hydraulic circuit body 10) with a simple configuration. Can do.

また、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）は、固定具を必要としていた従来と比べて、液圧回路体（油圧回路体１０）と電磁弁２０との間の接続に関わる構成が少ないので、接続完了後における液圧回路体（油圧回路体１０）と電磁弁２０との間の位置精度を高めることができる。このため、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）は、液圧回路体（油圧回路体１０）と電磁弁２０との間の位置ずれに起因する液圧のずれを抑えることができるので、制御対象物の制御精度を向上させることができる。   Further, the connection structure of the electromagnetic valve 20 and the hydraulic pressure control device (hydraulic control device 1) are provided between the hydraulic pressure circuit body (hydraulic circuit body 10) and the electromagnetic valve 20 as compared with the conventional case that requires a fixture. Therefore, the positional accuracy between the hydraulic circuit body (hydraulic circuit body 10) and the solenoid valve 20 after the connection is completed can be increased. For this reason, the connection structure of the electromagnetic valve 20 and the hydraulic pressure control device (hydraulic control device 1) are different in hydraulic pressure due to the positional deviation between the hydraulic pressure circuit body (hydraulic circuit body 10) and the electromagnetic valve 20. Therefore, the control accuracy of the controlled object can be improved.

また、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）は、固定具を必要としていた従来と比べて、液圧回路体（油圧回路体１０）と電磁弁２０との間の接続に関わる構成が少なく、電磁弁２０の挿入動作と回動動作だけで接続が完了するので、液圧制御装置（油圧制御装置１）の組付け作業性を向上させることができる。そして、この例示では、その回動動作に伴って、電磁弁２０の弁側接点２４ａと導電部材４０の弁用接点４１との間の電気的な接続も完了させることができる。このため、この例示の電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）は、従来と比べて、電磁弁２０と導電部材４０の電気的な接続作業を廃止することができるので、液圧制御装置（油圧制御装置１）の組付け作業性の更なる向上が可能になる。このように、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）は、組付け作業性を向上させることができるので、液圧制御装置（油圧制御装置１）の原価低減を図ることができる。   Further, the connection structure of the electromagnetic valve 20 and the hydraulic pressure control device (hydraulic control device 1) are provided between the hydraulic pressure circuit body (hydraulic circuit body 10) and the electromagnetic valve 20 as compared with the conventional case that requires a fixture. Since the connection is completed only by the insertion operation and the rotation operation of the electromagnetic valve 20, the assembly workability of the hydraulic control device (hydraulic control device 1) can be improved. In this example, the electrical connection between the valve-side contact 24a of the electromagnetic valve 20 and the valve contact 41 of the conductive member 40 can be completed along with the turning operation. For this reason, the connection structure and the hydraulic pressure control device (hydraulic control device 1) of the illustrated electromagnetic valve 20 can eliminate the electrical connection work between the electromagnetic valve 20 and the conductive member 40 as compared with the related art. Further, the assembly workability of the hydraulic control device (hydraulic control device 1) can be further improved. Thus, the connection structure of the electromagnetic valve 20 and the hydraulic control device (hydraulic control device 1) can improve the assembly workability, so that the cost of the hydraulic control device (hydraulic control device 1) can be reduced. Can be planned.

また、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）は、固定具を必要としていた従来と比べて、液圧回路体（油圧回路体１０）と電磁弁２０との間の接続に関わる構成を例えばデッドスペースに設けることができるので、液圧回路体（油圧回路体１０）や電磁弁２０の体格の大型化（言うなれば液圧制御装置の体格の大型化）を抑えることができる。寧ろ、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）は、固定具を必要としないので、その固定具に関わる構成専用のスペースが不要になり、液圧制御装置（油圧制御装置１）の体格の小型化が可能になる。このように、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）は、液圧制御装置（油圧制御装置１）の体格の大型化を抑えたり小型化を図ったりすることができるので、例えば使用する材料が少なくなって、原価低減を図ることができる。   Further, the connection structure of the electromagnetic valve 20 and the hydraulic pressure control device (hydraulic control device 1) are provided between the hydraulic pressure circuit body (hydraulic circuit body 10) and the electromagnetic valve 20 as compared with the conventional case that requires a fixture. For example, the configuration relating to the connection can be provided in a dead space, so that the size of the hydraulic circuit body (hydraulic circuit body 10) and the solenoid valve 20 can be increased (in other words, the size of the hydraulic control device can be increased). Can be suppressed. On the contrary, the connection structure of the electromagnetic valve 20 and the hydraulic pressure control device (hydraulic control device 1) do not require a fixture, so that a space dedicated to the configuration related to the fixture is not required, and the hydraulic pressure control device (hydraulic pressure device 1 The size of the control device 1) can be reduced. As described above, the connection structure of the solenoid valve 20 and the hydraulic control device (hydraulic control device 1) may suppress the size of the hydraulic control device (hydraulic control device 1) from increasing in size or downsizing. Therefore, for example, the amount of materials used is reduced, and the cost can be reduced.

ところで、この液圧制御装置（油圧制御装置１）においては、電磁弁２０に外部から入力荷重が加わったとしても、その入力荷重の方向が電磁弁２０を液圧回路体（油圧回路体１０）に対して軸周りに相対回転させる方向となる可能性は低い。このため、この液圧制御装置（油圧制御装置１）においては、液圧回路体（油圧回路体１０）と接続体５０（特に第１接続体５０Ａ）との間に強度の差を設けてもよい。例えば、液圧回路体（油圧回路体１０）は、接続体５０（特に第１接続体５０Ａ）よりも強度の高い高強度材料で成形する。この場合には、例えば、接続体５０を合成樹脂材料の絶縁性材料で成形し、液圧回路体（油圧回路体１０）を金属材料で成形する。つまり、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）においては、液圧回路体（油圧回路体１０）と電磁弁２０との間における軸周りの相対回転以外の相対移動に関して、接続体５０よりも高強度の液圧回路体（油圧回路体１０）を利用した第１接続構造体６０と第２接続構造体７０とに担わせる一方、そのような相対移動よりも発生頻度の低い軸周りの相対回転に関して、電磁弁２０と液圧回路体（油圧回路体１０）よりも低強度の接続体５０との間に設けた第３接続構造体８０に担わせている。これにより、電磁弁２０は、固定具を用いずとも、高強度の液圧回路体（油圧回路体１０）によって、この液圧回路体（油圧回路体１０）に対して強固に接続することができる。そして、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）においては、電磁弁２０が接続体５０よりも液圧回路体（油圧回路体１０）に対して強固に接続されることになるので、電磁弁２０に対して外部から入力荷重が加わった際の電磁弁２０から接続体５０に作用する負荷を軽減させることができる。このため、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）は、接続体５０、並びに、これに保持されている制御ユニット３０及び導電部材４０の耐久性を向上させることができる。また、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）では、接続完了後における液圧回路体（油圧回路体１０）と電磁弁２０との間の相対回転以外の相対移動を禁止させるために合成樹脂材料から成るロック機構を設けずとも、その相対移動を高強度な液圧回路体（油圧回路体１０）で禁止することができるので、この点からも耐久性の向上が可能になる。   By the way, in this hydraulic pressure control device (hydraulic control device 1), even if an input load is applied to the solenoid valve 20 from the outside, the direction of the input load is the same as that of the hydraulic valve circuit body (hydraulic circuit body 10). It is unlikely that the rotation direction is relative to the axis. For this reason, in this hydraulic control device (hydraulic control device 1), even if a difference in strength is provided between the hydraulic circuit body (hydraulic circuit body 10) and the connection body 50 (particularly the first connection body 50A). Good. For example, the hydraulic circuit body (hydraulic circuit body 10) is formed of a high-strength material having higher strength than the connection body 50 (particularly the first connection body 50A). In this case, for example, the connection body 50 is formed of an insulating material of a synthetic resin material, and the hydraulic circuit body (hydraulic circuit body 10) is formed of a metal material. That is, in the connection structure of the electromagnetic valve 20 and the hydraulic control device (hydraulic control device 1), relative movement other than relative rotation around the axis between the hydraulic circuit body (hydraulic circuit body 10) and the electromagnetic valve 20 is performed. The first connection structure 60 and the second connection structure 70 using a hydraulic circuit body (hydraulic circuit body 10) having a higher strength than that of the connection body 50 are used, and are generated more than such relative movement. Regarding the relative rotation around the axis with low frequency, the third connection structure 80 provided between the electromagnetic valve 20 and the connection body 50 having a lower strength than the hydraulic circuit body (hydraulic circuit body 10) is used. Thus, the solenoid valve 20 can be firmly connected to the hydraulic circuit body (hydraulic circuit body 10) by the high-strength hydraulic circuit body (hydraulic circuit body 10) without using a fixture. it can. In the connection structure of the electromagnetic valve 20 and the hydraulic control device (hydraulic control device 1), the electromagnetic valve 20 is more firmly connected to the hydraulic circuit body (hydraulic circuit body 10) than the connection body 50. As a result, the load acting on the connection body 50 from the electromagnetic valve 20 when an external input load is applied to the electromagnetic valve 20 can be reduced. Therefore, the connection structure of the electromagnetic valve 20 and the hydraulic control device (hydraulic control device 1) can improve the durability of the connection body 50, the control unit 30 and the conductive member 40 held by the connection body 50. it can. Further, in the connection structure of the electromagnetic valve 20 and the hydraulic pressure control device (hydraulic control device 1), the relative movement other than the relative rotation between the hydraulic pressure circuit body (hydraulic circuit body 10) and the electromagnetic valve 20 after the connection is completed. Relative movement can be prohibited by a high-strength hydraulic circuit body (hydraulic circuit body 10) without providing a lock mechanism made of a synthetic resin material in order to prohibit this. Is possible.

また、液圧回路体（油圧回路体１０）は、金属材料で成形することによって、合成樹脂材料等で成形されるよりも寸法公差を小さくすることができる。従って、この電磁弁２０の接続構造及び液圧制御装置（油圧制御装置１）では、接続完了後における液圧回路体（油圧回路体１０）と電磁弁２０との間の位置精度を更に高めることができる。   Moreover, the hydraulic circuit body (hydraulic circuit body 10) can be made smaller in dimensional tolerance by molding with a metal material than when molding with a synthetic resin material or the like. Therefore, in the connection structure of the electromagnetic valve 20 and the hydraulic control device (hydraulic control device 1), the positional accuracy between the hydraulic circuit body (hydraulic circuit body 10) and the electromagnetic valve 20 after the connection is further increased. Can do.

［変形例１］
本変形例は、前述した実施形態で１つの電磁弁２０に対して２つ設けていた第３接続構造体８０を１つのみに置き換えたものである。図１６の符号２は、本変形例の液圧制御装置の一例として挙げた油圧制御装置を示す。尚、実施形態と同等のものについては、説明の便宜上、その実施形態と同じ符号を付して説明を省略する。 [Modification 1]
In the present modification, two third connection structures 80 provided for one electromagnetic valve 20 in the above-described embodiment are replaced with only one. Reference numeral 2 in FIG. 16 indicates a hydraulic control apparatus cited as an example of a hydraulic pressure control apparatus according to this modification. In addition, about the thing equivalent to embodiment, the same code | symbol as the embodiment is attached | subjected for convenience of explanation, and description is abbreviate | omitted.

本変形例の油圧制御装置２は、前述した実施形態の油圧制御装置１において、１つの電磁弁２０に対応させて設けた２つの第３接続構造体８０を１つのみに減らしたものに相当する。この油圧制御装置２においては、実施形態と同じ電磁弁２０を用いるものとする。このため、その電磁弁２０には、第３被接続具８１が２箇所に設けられている。一方、この油圧制御装置２では、実施形態の油圧制御装置１において、接続体５０を下記の接続体１５０に置き換えることで、第３接続構造体８０が１つのみ配置されるように構成する。   The hydraulic control device 2 of this modification corresponds to the hydraulic control device 1 of the above-described embodiment in which the two third connection structures 80 provided corresponding to one electromagnetic valve 20 are reduced to only one. To do. In this hydraulic control device 2, the same solenoid valve 20 as in the embodiment is used. For this reason, the solenoid valve 20 is provided with the third connected tool 81 at two locations. On the other hand, the hydraulic control device 2 is configured such that only one third connection structure 80 is arranged in the hydraulic control device 1 of the embodiment by replacing the connection body 50 with the following connection body 150.

本変形例の接続体１５０は、実施形態の接続体５０において、第１接続体５０Ａを第１接続体１５０Ａに置き換えたものに相当する。そして、その第１接続体１５０Ａは、実施形態の第１接続体５０Ａにおいて、それぞれの貫通孔５１に対して設けられている２つの第３接続具８２を１つ減らしたものに相当する（図１６及び図１７）。これにより、電磁弁２０においては、一方の第３被接続具８１しか第３接続具８２に係合しない。従って、本変形例の油圧制御装置２においては、１つの電磁弁２０に対応させた第３接続構造体８０が１つのみ設けられることになる。この油圧制御装置２においては、電磁弁２０を実施形態と同じように組み付けることによって、一方の第３被接続具８１と第３接続具８２とが係合し、油圧回路体１０と電磁弁２０との間における軸周りの相対回転を禁止させることができる。   The connection body 150 of the present modification corresponds to the connection body 50 of the embodiment in which the first connection body 50A is replaced with the first connection body 150A. The first connection body 150A corresponds to the first connection body 50A according to the embodiment in which the two third connection tools 82 provided for the respective through holes 51 are reduced by one (see FIG. 16 and FIG. 17). Thereby, in the solenoid valve 20, only one third connected tool 81 is engaged with the third connecting tool 82. Therefore, in the hydraulic control device 2 of the present modification, only one third connection structure 80 corresponding to one electromagnetic valve 20 is provided. In the hydraulic control apparatus 2, by assembling the electromagnetic valve 20 in the same manner as in the embodiment, one third connected tool 81 and the third connecting tool 82 are engaged, and the hydraulic circuit body 10 and the electromagnetic valve 20 are engaged. Relative rotation around the axis can be prohibited.

このように、本変形例の液圧制御装置（油圧制御装置２）は、第３接続構造体８０が１つだけではあるが、この第３接続構造体８０を成す第３被接続具８１と第３接続具８２とを係合させることができるので、前述した実施形態の液圧制御装置（油圧制御装置１）と同じように、電磁弁２０の軸周りの相対回転を禁止することができる。   As described above, the hydraulic pressure control device (hydraulic control device 2) of the present modification has only one third connection structure 80, but the third connected device 81 constituting the third connection structure 80 and Since the third connection tool 82 can be engaged, relative rotation around the axis of the solenoid valve 20 can be prohibited as in the case of the hydraulic control device (hydraulic control device 1) of the above-described embodiment. .

更に、実施形態の液圧制御装置（油圧制御装置１）においては、第３接続構造体８０を複数備えているので、全ての第３接続構造体８０で第３被接続具８１と第３接続具８２の形状や配置等に関わる設計公差を小さくしなければ、例えば、１つの第３接続構造体８０で第３被接続具８１と第３接続具８２とを係合させることができたとしても、残りの第３接続構造体８０で第３被接続具８１と第３接続具８２とを係合させることができなくなる可能性がある。しかしながら、本変形例の液圧制御装置（油圧制御装置２）は、第３接続構造体８０が１つだけなので、実施形態の液圧制御装置（油圧制御装置１）のように設計公差を厳しく管理しなくても、その第３被接続具８１と第３接続具８２とを係合させることができる。このため、本変形例の液圧制御装置（油圧制御装置２）は、実施形態の液圧制御装置（油圧制御装置１）と比較して、原価の上昇を抑えた第３接続構造体８０を設けることができる。   Furthermore, since the hydraulic control device (hydraulic control device 1) of the embodiment includes a plurality of third connection structures 80, the third connection structure 81 and the third connection are connected to all the third connection structures 80. Unless design tolerances related to the shape, arrangement, etc. of the tool 82 are reduced, for example, it is assumed that the third connected device 81 and the third connected device 82 can be engaged with one third connection structure 80. However, there is a possibility that the third connected device 81 and the third connected device 82 cannot be engaged by the remaining third connection structure 80. However, since the hydraulic pressure control device (hydraulic pressure control device 2) of this modification has only one third connection structure 80, the design tolerance is strict as in the hydraulic pressure control device (hydraulic pressure control device 1) of the embodiment. Even if it does not manage, the 3rd to-be-connected device 81 and the 3rd connecting device 82 can be engaged. For this reason, the hydraulic control device (hydraulic control device 2) of the present modification includes the third connection structure 80 that suppresses an increase in cost compared to the hydraulic control device (hydraulic control device 1) of the embodiment. Can be provided.

また更に、本変形例の第１接続体１５０Ａは、実施形態の第１接続体５０Ａから第３接続具８２を１つ減らしたものとなっているので、実施形態の液圧制御装置（油圧制御装置１）と同じように、電磁弁２０の双方の第３被接続具８１を貫通孔５１に各々の挿通部５１ａから収容することができる。そして、本変形例の導電部材４０においては、実施形態の液圧制御装置（油圧制御装置１）と同じように、電磁弁２０の双方の第３被接続具８１の位置に合わせて弁用接点４１が１つずつ配置されており、それぞれの第３被接続具８１の内の一方のみに端子２４が内包されていたとしても、この端子２４の弁側接点２４ａを弁用接点４１に対して電気的に接続させることができる。このため、本変形例の液圧制御装置（油圧制御装置２）は、第３接続構造体８０が１つだけではあるが、電磁弁２０を軸周りに１８０度ずらして組み付けることもできる。   Furthermore, since the first connection body 150A of the present modification is obtained by reducing the third connection tool 82 by one from the first connection body 50A of the embodiment, the hydraulic pressure control device (hydraulic control of the embodiment) Similarly to the apparatus 1), the third connected devices 81 of both the electromagnetic valves 20 can be accommodated in the through holes 51 from the respective insertion portions 51a. Then, in the conductive member 40 of the present modification, the valve contact point is adjusted in accordance with the positions of the third connected devices 81 of the electromagnetic valve 20 in the same manner as the hydraulic control device (hydraulic control device 1) of the embodiment. 41 is arranged one by one, and even if the terminal 24 is included in only one of the third connected devices 81, the valve-side contact 24a of the terminal 24 is connected to the valve contact 41. It can be electrically connected. For this reason, the hydraulic control device (hydraulic control device 2) of the present modification has only one third connection structure 80, but can also be assembled with the electromagnetic valve 20 shifted by 180 degrees around the axis.

［変形例２］
本変形例は、前述した変形例１の液圧制御装置（油圧制御装置２）と同様に、１つの電磁弁２０に対する第３接続構造体８０を１つのみとしたものである。但し、本変形例では、その電磁弁２０を図１８及び図１９に示す電磁弁１２０に置き換える。本変形例で用いる電磁弁１２０は、実施形態や変形例１の電磁弁２０において、２つの第３被接続具８１の内の一方を削除したものに相当する（図１９）。この電磁弁１２０は、自らが具備している１つの第３被接続具８１の内方に端子２４を配置している。図１８の符号３は、本変形例の液圧制御装置の一例として挙げた油圧制御装置を示す。尚、実施形態や変形例１と同等のものについては、説明の便宜上、その実施形態や変形例１と同じ符号を付して説明を省略する。 [Modification 2]
In the present modification, only one third connection structure 80 for one electromagnetic valve 20 is provided, similar to the hydraulic pressure control apparatus (hydraulic control apparatus 2) in the first modification described above. However, in this modification, the solenoid valve 20 is replaced with the solenoid valve 120 shown in FIGS. The solenoid valve 120 used in this modification corresponds to the solenoid valve 20 of the embodiment or the modification 1 in which one of the two third connected devices 81 is deleted (FIG. 19). This electromagnetic valve 120 has a terminal 24 disposed inside one third connected tool 81 provided by itself. Reference numeral 3 in FIG. 18 indicates a hydraulic control apparatus cited as an example of a hydraulic control apparatus according to this modification. In addition, about the thing equivalent to embodiment and the modification 1, the same code | symbol as the embodiment and the modification 1 is attached | subjected for convenience of explanation, and description is abbreviate | omitted.

本変形例の油圧制御装置３は、変形例１の油圧制御装置２において、接続体１５０を接続体２５０に置き換え、かつ、導電部材４０を導電部材１４０に置き換えたものである（図１８及び図２０）。   The hydraulic control device 3 of the present modification is obtained by replacing the connection body 150 with the connection body 250 and replacing the conductive member 40 with the conductive member 140 in the hydraulic control device 2 of the first modification (see FIGS. 18 and 18). 20).

本変形例の接続体２５０は、変形例１の接続体１５０において、第１接続体１５０Ａを第１接続体２５０Ａに置き換えたものに相当する。そして、その第１接続体２５０Ａは、変形例１の第１接続体１５０Ａにおいて、それぞれの貫通孔５１を貫通孔２５１に置き換えたものに相当する。   The connection body 250 according to the present modification corresponds to the connection body 150 according to the first modification, in which the first connection body 150A is replaced with the first connection body 250A. The first connection body 250 </ b> A corresponds to the first connection body 150 </ b> A according to the first modification in which each through hole 51 is replaced with the through hole 251.

その貫通孔２５１は、変形例１の貫通孔５１と同じように、電磁弁１２０の収容体２３が挿通されるものであり、その電磁弁１２０が有する２つの第１被接続具６１と１つの第３被接続具８１とを避けた形状に形成する。このため、この貫通孔２５１は、変形例１の貫通孔５１と同じように、第３被接続具８１の挿通が可能な挿通部２５１ａを有する。但し、本変形例の貫通孔２５１は、電磁弁１２０が有する第３被接続具８１の数量に合わせて１箇所にのみ挿通部２５１ａを有しており、その挿通部２５１ａの位置に第３被接続具８１の位置を合わせなければ、収容体２３が挿通されないように形成している。第３接続具８２は、その挿通部２５１ａの内方に配置する。従って、本変形例の油圧制御装置３においては、１つの電磁弁１２０に対応させた第３接続構造体８０が１つのみ設けられることになる。この油圧制御装置３においては、挿通部２５１ａの位置に第３被接続具８１の位置を合わせて電磁弁１２０を貫通孔２５１に挿入し、この電磁弁１２０を軸周りに回転させることによって、第３被接続具８１と第３接続具８２とが係合し、油圧回路体１０と電磁弁１２０との間における軸周りの相対回転を禁止させることができる。   The through-hole 251 is the same as the through-hole 51 of the first modified example, into which the accommodating body 23 of the electromagnetic valve 120 is inserted, and the two first connected devices 61 included in the electromagnetic valve 120 and one It is formed in a shape that avoids the third connected tool 81. For this reason, the through-hole 251 has an insertion portion 251a through which the third connected tool 81 can be inserted, similarly to the through-hole 51 of the first modification. However, the through-hole 251 of this modification has an insertion portion 251a only at one location in accordance with the quantity of the third connection tool 81 included in the electromagnetic valve 120, and the third insertion target 251a is located at the position of the insertion portion 251a. If the position of the connection tool 81 is not adjusted, the container 23 is formed so as not to be inserted. The 3rd connection tool 82 is arrange | positioned inside the insertion part 251a. Therefore, in the hydraulic control device 3 according to this modification, only one third connection structure 80 corresponding to one electromagnetic valve 120 is provided. In the hydraulic control device 3, the position of the third connected tool 81 is aligned with the position of the insertion portion 251a, the electromagnetic valve 120 is inserted into the through hole 251, and the electromagnetic valve 120 is rotated around the axis, thereby The three to-be-connected tools 81 and the third connecting tool 82 are engaged, and relative rotation around the axis between the hydraulic circuit body 10 and the electromagnetic valve 120 can be prohibited.

本変形例の導電部材１４０は、実施形態や変形例１の導電部材４０において、１つの電磁弁２０に対して設けた２つの弁用接点４１の内、一方を削除したものに相当する。この導電部材１４０は、挿通部２５１ａの内方にのみ弁用接点４１が配置されるように形成している。   The conductive member 140 of this modification corresponds to the conductive member 40 of the embodiment or modification 1 in which one of the two valve contacts 41 provided for one electromagnetic valve 20 is deleted. The conductive member 140 is formed such that the valve contact 41 is disposed only inside the insertion portion 251a.

このように、本変形例の液圧制御装置（油圧制御装置３）は、第３接続構造体８０が１つだけになっているので、変形例１の液圧制御装置（油圧制御装置２）と同じように、電磁弁１２０の軸周りの相対回転を禁止することができる。   Thus, since the hydraulic pressure control apparatus (hydraulic pressure control apparatus 3) of this modification has only one third connection structure 80, the hydraulic pressure control apparatus (hydraulic control apparatus 2) of modification example 1 Similarly, relative rotation around the axis of the solenoid valve 120 can be prohibited.

更に、本変形例の液圧制御装置（油圧制御装置３）は、第３接続構造体８０が１つだけなので、変形例１の液圧制御装置（油圧制御装置２）と同じように、その第３接続構造体８０に要する原価の上昇を抑えることができる。そして、この液圧制御装置（油圧制御装置３）では、変形例１の液圧制御装置（油圧制御装置２）と比較して、弁用接点４１を１つ省くことができるので、この点から原価の低減も可能になる。   Furthermore, since the hydraulic pressure control device (hydraulic pressure control device 3) of the present modification has only one third connection structure 80, as in the hydraulic pressure control device (hydraulic control device 2) of the first modification, An increase in cost required for the third connection structure 80 can be suppressed. In this hydraulic pressure control device (hydraulic control device 3), one valve contact 41 can be omitted as compared with the hydraulic pressure control device (hydraulic control device 2) of the first modification. Costs can be reduced.

また更に、本変形例の液圧制御装置（油圧制御装置３）は、貫通孔２５１の形状によって、或る特定の１つの方向にしか電磁弁１２０を組み付けることができないので、電磁弁１２０の誤組付けを防ぐことができる。   Furthermore, since the hydraulic pressure control device (hydraulic control device 3) of the present modification can assemble the electromagnetic valve 120 only in one specific direction depending on the shape of the through hole 251, the error of the electromagnetic valve 120 is incorrect. Assembly can be prevented.

［変形例３］
本変形例は、電磁弁２０の誤組付けを防ぐためのものである。前述した実施形態や変形例１で図示した電磁弁２０は、２つ第３被接続具８１の内の一方にのみ端子２４を内包させている。このため、実施形態の液圧制御装置（油圧制御装置１）や変形例１の液圧制御装置（油圧制御装置２）では、電磁弁２０を軸周りに１８０度ずらして組み付けたとしても、その端子２４の弁側接点２４ａと導電部材４０の弁用接点４１とを電気的に接続させるように、２つの挿通部５１ａの内方に弁用接点４１を１つずつ配置している。つまり、実施形態の液圧制御装置（油圧制御装置１）や変形例１の液圧制御装置（油圧制御装置２）においては、使用されない弁用接点４１を電磁弁２０毎に１箇所ずつ設けることによって、電磁弁２０の誤組付けを防いでいる。しかしながら、そのような不使用の弁用接点４１は、原価の上昇の要因となる可能性がある。そこで、本変形例では、原価の上昇を抑えつつ電磁弁２０の誤組付けを防ぐことができるように構成する。図２１の符号４は、本変形例の液圧制御装置の一例として挙げた油圧制御装置を示す。尚、実施形態や各変形例１，２と同等のものについては、説明の便宜上、その実施形態や各変形例１，２と同じ符号を付して説明を省略する。 [Modification 3]
This modification is for preventing erroneous assembly of the solenoid valve 20. In the electromagnetic valve 20 illustrated in the above-described embodiment and modification 1, the terminal 24 is included only in one of the two third connected devices 81. For this reason, in the hydraulic pressure control device (hydraulic pressure control device 1) of the embodiment and the hydraulic pressure control device (hydraulic pressure control device 2) of the modified example 1, even if the electromagnetic valve 20 is assembled with being shifted by 180 degrees around the axis, One valve contact 41 is disposed inside each of the two insertion portions 51a so that the valve contact 24a of the terminal 24 and the valve contact 41 of the conductive member 40 are electrically connected. That is, in the hydraulic pressure control device (hydraulic pressure control device 1) of the embodiment and the hydraulic pressure control device (hydraulic pressure control device 2) of the first modified example, the valve contact 41 that is not used is provided for each electromagnetic valve 20. Thus, the incorrect assembly of the solenoid valve 20 is prevented. However, such unused valve contacts 41 may cause an increase in cost. In view of this, the present modification is configured such that erroneous assembly of the solenoid valve 20 can be prevented while suppressing an increase in cost. Reference numeral 4 in FIG. 21 indicates a hydraulic control apparatus cited as an example of the hydraulic control apparatus according to this modification. In addition, about the thing equivalent to embodiment and each modification 1, 2, the same code | symbol as the embodiment and each modification 1, 2 is attached | subjected for convenience of explanation, and description is abbreviate | omitted.

本変形例の油圧制御装置４は、前述した実施形態の油圧制御装置１又は変形例１の油圧制御装置２において、導電部材４０を変形例２の導電部材１４０に置き換えると共に（図２１及び図２２）、電磁弁２０と油圧回路体１０又は接続体５０（１５０）との間に、電磁弁２０の誤組付け防止機構を設けたものに相当する。このため、この油圧制御装置４においては、貫通孔５１の２つの挿通部５１ａの内の一方にのみ弁用接点４１が配置される（図２２）。   The hydraulic control device 4 of the present modified example replaces the conductive member 40 with the conductive member 140 of the modified example 2 in the hydraulic control device 1 of the above-described embodiment or the hydraulic control device 2 of the modified example 1 (FIGS. 21 and 22). ), Which corresponds to an electromagnetic valve 20 misassembly prevention mechanism provided between the electromagnetic valve 20 and the hydraulic circuit body 10 or the connecting body 50 (150). For this reason, in this hydraulic control device 4, the valve contact 41 is disposed only on one of the two insertion portions 51a of the through hole 51 (FIG. 22).

ここでは、実施形態の油圧制御装置１をベースにして誤組付け防止機構の説明を行うが、変形例１の油圧制御装置２がベースとなる場合でも、その説明と同じように誤組付け防止機構を構成することで同様の効果を得ることができる。   Here, the misassembly prevention mechanism will be described based on the hydraulic control device 1 of the embodiment. However, even when the hydraulic control device 2 of the first modification is used as a base, erroneous assembly prevention is performed in the same manner as described above. The same effect can be obtained by configuring the mechanism.

誤組付け防止機構は、電磁弁が設計通りの正規の組付け位置に組み付けられるときにのみ互いに係合し合うように形成及び配置された第１係合部と第２係合部とを備える。このため、この誤組付け防止機構は、電磁弁の誤組付けを防ぐことができるので、この電磁弁を設計通りの正規の組付け位置にのみ組み付けさせることができる。本変形例の油圧制御装置４においては、この誤組付け防止機構の第１係合部と第２係合部の構成に応じて、実施形態の油圧制御装置１における電磁弁２０と油圧回路体１０と接続体５０を適宜別の形態のものに置き換える。   The erroneous assembly prevention mechanism includes a first engagement portion and a second engagement portion that are formed and arranged so as to engage with each other only when the solenoid valve is assembled at a normal assembly position as designed. . For this reason, this erroneous assembly prevention mechanism can prevent the electromagnetic valve from being erroneously assembled, so that the electromagnetic valve can be assembled only at the regular assembly position as designed. In the hydraulic control device 4 of the present modification, the electromagnetic valve 20 and the hydraulic circuit body in the hydraulic control device 1 of the embodiment are configured according to the configuration of the first engagement portion and the second engagement portion of the erroneous assembly prevention mechanism. 10 and the connection body 50 are appropriately replaced with different forms.

例えば、第１係合部は、電磁弁と油圧回路体又は接続体との内の一方に対して、突出させた状態の突出部として設ける。そして、第２係合部は、その内の他方に対して、電磁弁が設計通りの正規の組付け位置に組み付けられるときにのみ第１係合部の挿入が可能な溝部又は切欠き部又は貫通孔部として設ける。   For example, the first engaging portion is provided as a protruding portion in a state of protruding from one of the solenoid valve and the hydraulic circuit body or the connecting body. And the second engaging part is a groove part or a notch part in which the first engaging part can be inserted only when the solenoid valve is assembled at the normal assembly position as designed with respect to the other of the second engaging parts. It is provided as a through hole.

この第１係合部と第２係合部は、誤組付け防止機能の専用のものとして設けてもよく、誤組付け防止機能とは別の機能のために設けられるものと併用させてもよい。以下においては、後者を具体例として挙げて説明する。   The first engaging portion and the second engaging portion may be provided exclusively for the misassembly prevention function, or may be used in combination with those provided for a function different from the misassembly prevention function. Good. In the following, the latter will be described as a specific example.

例えば、電磁弁と油圧回路体との間には、第１接続構造体６０が設けられている。そして、その第１接続構造体６０においては、突出部となる第１被接続具６１と溝部となる第１接続具６２とが互いに係合し合うものとして設けられている。このため、本変形例の油圧制御装置４では、この第１接続構造体６０を誤組付け防止機構としても利用する。   For example, a first connection structure 60 is provided between the solenoid valve and the hydraulic circuit body. And in the 1st connection structure 60, the 1st to-be-connected tool 61 used as a protrusion part and the 1st connecting tool 62 used as a groove part are provided as what mutually engages. For this reason, in the hydraulic control device 4 of the present modification, the first connection structure 60 is also used as an erroneous assembly prevention mechanism.

第１接続構造体６０が１つの場合には、正規の組付け位置以外で第１被接続具６１が油圧回路体又は接続体に引っ掛かり、これによって電磁弁が油圧回路体及び接続体に対して組み付けられないように第１被接続具６１と第１接続具６２とを形成及び配置する。これにより、この第１接続構造体６０は、誤組付け防止機構としても利用することができる。   In the case where there is one first connection structure 60, the first connected device 61 is caught on the hydraulic circuit body or the connection body other than the normal assembly position, whereby the electromagnetic valve is connected to the hydraulic circuit body and the connection body. The first connected tool 61 and the first connecting tool 62 are formed and arranged so as not to be assembled. Thereby, this 1st connection structure 60 can be utilized also as an incorrect assembly | attachment prevention mechanism.

一方、第１接続構造体６０が複数の場合には、実施形態の油圧制御装置１のように、それぞれの第１接続構造体６０が軸周りに略等間隔で配置されていると、電磁弁を正規の組付け位置から軸周りに回転させたとしても、正規の組付け位置とは異なる所定の位置で全ての第１被接続具６１を各々の第１接続具６２の軸線方向溝部６２Ａに挿入させることができる。このため、本変形例の油圧制御装置４では、このような複数の第１接続構造体６０を誤組付け防止機構としても利用する場合、それぞれの第１接続構造体６０の内の少なくとも１つについて、隣り合う一方の第１接続構造体６０との軸周りの間隔（言うなれば弧長）を成す角度（所謂中心角）と隣り合う他方の第１接続構造体６０との軸周りの間隔を成す角度とが異なる角度となるように配置する。これにより、この誤組付け防止機構は、電磁弁が軸周りにおける或る１つの特定の位置（正規の組付け位置）のときにだけ、全ての第１被接続具６１を各々の第１接続具６２の軸線方向溝部６２Ａに挿入させることができるので、電磁弁の誤組付けを防ぐことができる。   On the other hand, when there are a plurality of first connection structures 60, when the first connection structures 60 are arranged at substantially equal intervals around the axis as in the hydraulic control device 1 of the embodiment, Even if the shaft is rotated around the axis from the regular assembly position, all the first connected devices 61 are inserted into the axial groove portions 62A of the first connection devices 62 at a predetermined position different from the regular assembly position. Can be inserted. For this reason, in the hydraulic control device 4 of the present modification, when such a plurality of first connection structures 60 are also used as an erroneous assembly prevention mechanism, at least one of the first connection structures 60 is used. , An angle (so-called central angle) forming an interval around the axis with one adjacent first connection structure 60 (in other words, an arc length) and an interval around the axis with the other adjacent first connection structure 60 It arrange | positions so that it may become an angle different from the angle which comprises. As a result, this erroneous assembly prevention mechanism allows all the first connected devices 61 to be connected to the respective first connections only when the solenoid valve is in one particular position (regular assembly position) around the axis. Since it can be inserted into the axial groove portion 62A of the tool 62, erroneous assembly of the electromagnetic valve can be prevented.

具体的に、本変形例の油圧制御装置４では、実施形態の油圧制御装置１において、電磁弁２０を下記の電磁弁２２０に置き換える（図２３）。その電磁弁２２０は、実施形態の電磁弁２０において、誤組付け防止機構の第１係合部としての突出部を設けたものに相当する。この例示の電磁弁２２０では、それぞれの第１被接続具６１の軸周りにおける配置について、それぞれの第１被接続具６１の軸周りの一方の間隔を成す一方の角度（中心角）θ１が他方の間隔を成す他方の角度（中心角）θ２よりも小さくなるようにする。本変形例の油圧制御装置４では、そのそれぞれの第１被接続具６１の位置に合わせて第１接続具６２を配置する。その第１接続具６２は、誤組付け防止機構の第２係合部としての溝部に相当する。   Specifically, in the hydraulic control device 4 of this modification, the electromagnetic valve 20 is replaced with the following electromagnetic valve 220 in the hydraulic control device 1 of the embodiment (FIG. 23). The electromagnetic valve 220 corresponds to the electromagnetic valve 20 of the embodiment provided with a protruding portion as the first engagement portion of the erroneous assembly prevention mechanism. In this exemplary solenoid valve 220, with respect to the arrangement around the axis of each first connected tool 61, one angle (center angle) θ <b> 1 forming one interval around the axis of each first connected tool 61 is the other. It is made to be smaller than the other angle (center angle) θ2 forming the interval of. In the hydraulic control device 4 of the present modification, the first connection tool 62 is arranged in accordance with the position of each first connected tool 61. The first connector 62 corresponds to a groove portion as a second engaging portion of the erroneous assembly preventing mechanism.

本変形例の第１接続具６２は、実施形態の油圧制御装置１と同じように、油圧回路体１１０に設けている（図２４）。その油圧回路体１１０は、実施形態の油圧回路体１０において２つの第１接続具６２の配置を変えたものに相当しており、その間の軸周りにおける間隔を成す一方の角度（中心角）θａをθ１に設定し、かつ、他方の角度（中心角）θｂをθ２に設定する。   The first connector 62 of this modification is provided in the hydraulic circuit body 110 in the same manner as the hydraulic control device 1 of the embodiment (FIG. 24). The hydraulic circuit body 110 corresponds to the hydraulic circuit body 10 according to the embodiment in which the arrangement of the two first connecting members 62 is changed, and one angle (center angle) θa forming an interval around the axis therebetween. Is set to θ1, and the other angle (center angle) θb is set to θ2.

本変形例の油圧制御装置４は、そのような互いの中心角を変えて配置された第１接続構造体６０を備えているので、電磁弁２２０を正規の組付け位置に組み付けようとしているならば、それぞれの第１被接続具６１が各々の第１接続具６２の軸線方向溝部６２Ａに挿入されて（図２５）、電磁弁２２０が油圧回路体１１０及び接続体５０に対して正しく組み付けられる。一方、この油圧制御装置４は、その正規の組付け位置に対して電磁弁２２０を１８０度ずらして組み付けようとしているならば、一方の第１被接続具６１が一方の第１接続具６２の軸線方向溝部６２Ａに挿入されようとしたとしても、他方の第１被接続具６１が他方の第１接続具６２の軸線方向溝部６２Ａに挿入されずに油圧回路体１１０の壁面に引っ掛かるので（図２６）、電磁弁２２０を油圧回路体１１０及び接続体５０に対して組み付けることができない。   Since the hydraulic control device 4 of the present modification includes the first connection structure 60 arranged with the mutual center angles changed, if the electromagnetic valve 220 is to be assembled at the regular assembly position. For example, each first connected tool 61 is inserted into the axial groove 62A of each first connecting tool 62 (FIG. 25), and the electromagnetic valve 220 is correctly assembled to the hydraulic circuit body 110 and the connecting body 50. . On the other hand, in the hydraulic control device 4, if the electromagnetic valve 220 is to be assembled with a shift of 180 degrees with respect to the regular assembly position, one first connected device 61 is connected to one of the first connected devices 62. Even if it is about to be inserted into the axial groove portion 62A, the other first connected tool 61 is not inserted into the axial groove portion 62A of the other first connecting tool 62 and is caught on the wall surface of the hydraulic circuit body 110 (FIG. 26) The electromagnetic valve 220 cannot be assembled to the hydraulic circuit body 110 and the connection body 50.

このように、本変形例の液圧制御装置（油圧制御装置４）は、電磁弁２２０の誤組付けを防ぐことができるので、この電磁弁２２０が正規の組付け位置に組み付けられる。従って、この液圧制御装置（油圧制御装置４）は、電磁弁２２０に端子２４が１つしか設けられていなかったとしても、その端子２４の弁側接点２４ａを導電部材４０の１箇所のみの弁用接点４１に対して電気的に接続させることができる。よって、この液圧制御装置（油圧制御装置４）は、不使用となってしまう弁用接点４１を設ける必要が無くなるので、原価の低減を図ることができる。更に、この液圧制御装置（油圧制御装置４）は、電磁弁２２０に端子２４が２箇所に設けられている場合であっても、その内の一方の弁側接点２４ａを導電部材４０の１箇所のみの弁用接点４１に対して電気的に接続させることができる。   As described above, the hydraulic pressure control device (hydraulic control device 4) according to the present modification can prevent the electromagnetic valve 220 from being erroneously assembled, so that the electromagnetic valve 220 is assembled at the proper assembly position. Therefore, even if this hydraulic pressure control device (hydraulic control device 4) has only one terminal 24 on the electromagnetic valve 220, the valve-side contact 24a of the terminal 24 is connected to only one portion of the conductive member 40. It can be electrically connected to the valve contact 41. Accordingly, the hydraulic pressure control device (hydraulic control device 4) does not need to be provided with the valve contact 41 that is not used, and therefore the cost can be reduced. Further, this hydraulic pressure control device (hydraulic control device 4) has one of the valve-side contacts 24 a of the conductive member 40 even if the electromagnetic valve 220 is provided with two terminals 24. It can be electrically connected to the valve contact 41 only at the location.

ところで、本変形例の油圧制御装置４においては、第３接続構造体８０が設けられている。そして、その第３接続構造体８０においては、突出部となる第３被接続具８１と溝部となる第３接続具８２とが互いに係合し合うものとして設けられている。このため、本変形例の油圧制御装置４では、図示しないが、この第３接続構造体８０を誤組付け防止機構として利用することもできる。この場合には、第３接続構造体８０が１つのみ設けられているのであれば、正規の組付け位置以外で第３被接続具８１が油圧回路体又は接続体に引っ掛かり、これによって電磁弁が油圧回路体及び接続体に対して組み付けられないように第３被接続具８１と第３接続具８２とを形成及び配置する。一方、第３接続構造体８０が複数の場合には、それぞれの第３接続構造体８０の内の少なくとも１つについて、隣り合う一方の第３接続構造体８０との軸周りの間隔（弧長）を成す角度（中心角）と隣り合う他方の第３接続構造体８０との軸周りの間隔を成す角度とが異なる角度となるように配置する。本変形例の油圧制御装置４は、このように構成したとしても、先の例示と同様の効果を得ることができる。   By the way, in the hydraulic control apparatus 4 of this modification, the 3rd connection structure 80 is provided. And in the 3rd connection structure 80, the 3rd to-be-connected tool 81 used as a protrusion part and the 3rd connecting tool 82 used as a groove part are provided as what mutually engages. For this reason, in the hydraulic control device 4 of this modification, although not shown, the third connection structure 80 can be used as an erroneous assembly prevention mechanism. In this case, if only one third connection structure 80 is provided, the third connected device 81 is caught by the hydraulic circuit body or the connection body at a position other than the normal assembly position. The third connected tool 81 and the third connected tool 82 are formed and arranged so as not to be assembled to the hydraulic circuit body and the connected body. On the other hand, when there are a plurality of third connection structures 80, at least one of the respective third connection structures 80 has an interval around the axis (arc length) between the adjacent one of the third connection structures 80. ) And the other third connection structure 80 adjacent to each other are arranged such that the angle forming the interval around the axis is different. Even if the hydraulic control device 4 of the present modification is configured as described above, the same effects as those of the previous examples can be obtained.

また、先の例示では、２つの第１被接続具６１と２つの第１接続具６２とを各々同等の形状に形成しているので、２つの第１被接続具６１の軸周りの間隔と２つの第１接続具６２の軸周りの間隔とを一方が挟角（θ１、θａ）となり、他方が鈍角（θ２、θｂ）となるように設定している。これに対して、本変形例の液圧制御装置（油圧制御装置４）は、図示しないが、２つの第１被接続具６１の内の一方を他方とは異なる形状に形成すると共に、２つの第１接続具６２の内の一方を他方とは異なる形状に形成し、第１被接続具６１と第１接続具６２との組み合わせが逆になったときにのみ第１被接続具６１が第１接続具６２の軸線方向溝部６２Ａに挿入されないように設定してもよい。この場合には、２つの第１被接続具６１を軸周りに１８０度ずらして配置し、かつ、２つの第１接続具６２を軸周りに１８０度ずらして配置してもよい。その形状の異なる２つの第１被接続具６１を備えた電磁弁を正規の組付け位置に組み付けようとしているときには、一方の第１被接続具６１が一方の第１接続具６２の軸線方向溝部６２Ａに挿入されると共に、他方の第１被接続具６１が他方の第１接続具６２の軸線方向溝部６２Ａに挿入されるので、この電磁弁が正しく組み付けられる。これに対して、この電磁弁を１８０度ずらして組み付けようとしているときには、例えば、一方の第１被接続具６１の方が他方の第１被接続具６１よりも体格が大きければ、その一方の第１被接続具６１を他方の第１接続具６２の軸線方向溝部６２Ａに挿入することができないので、この電磁弁の組付けが行えない。このように、本変形例の液圧制御装置（油圧制御装置４）は、互いに異なる形状の複数の第１被接続具６１と互いに異なる形状の複数の第１接続具６２とを設けることによっても、先の例示と同様の効果を得ることができる。この考え方は、第３接続構造体８０（第３被接続具８１と第３接続具８２）で誤組付け防止機構を構成する際にも適用可能である。   In the above illustration, since the two first connected devices 61 and the two first connected devices 62 are formed in the same shape, the distance between the axes of the two first connected devices 61 The interval around the axis of the two first connection tools 62 is set so that one is an included angle (θ1, θa) and the other is an obtuse angle (θ2, θb). On the other hand, the hydraulic pressure control device (hydraulic control device 4) of the present modification is not shown, but one of the two first connected devices 61 is formed in a shape different from the other, and the two One of the first connection tools 62 is formed in a shape different from the other, and the first connection tool 61 is only connected to the first connection tool 61 when the combination of the first connection tool 61 and the first connection tool 62 is reversed. You may set so that it may not insert in the axial direction groove part 62A of the 1 connector 62. FIG. In this case, the two first connected devices 61 may be arranged to be shifted 180 degrees around the axis, and the two first connected devices 62 may be arranged to be shifted 180 degrees around the axis. When the solenoid valve including the two first connected devices 61 having different shapes is to be assembled at the regular assembly position, one of the first connected devices 61 is the axial groove portion of the first connected device 62. Since the other first connected tool 61 is inserted into the axial groove 62A of the other first connecting tool 62, the electromagnetic valve is correctly assembled. On the other hand, when trying to assemble this solenoid valve by shifting 180 degrees, for example, if one first connected device 61 is larger than the other first connected device 61, one of the first connected devices 61 Since the 1st to-be-connected tool 61 cannot be inserted in the axial direction groove part 62A of the other 1st connecting tool 62, this electromagnetic valve cannot be assembled | attached. As described above, the hydraulic pressure control device (hydraulic control device 4) according to the present modification also includes a plurality of first connected devices 61 having different shapes and a plurality of first connecting devices 62 having different shapes. The effect similar to the previous illustration can be obtained. This concept can also be applied when the misassembly prevention mechanism is configured by the third connecting structure 80 (the third connected tool 81 and the third connecting tool 82).

また、誤組付け防止機構は、図示しないが、電磁弁を正規の組付け位置に対して軸周りにずらした際に、この電磁弁を軸線方向に挿入することはできるが、挿入後の電磁弁を軸周りに回転させることができないように第１係合部と第２係合部とを形成してもよい。本変形例の油圧制御装置４は、このように構成したとしても、先の例示と同様の効果を得ることができる。   Although not shown in the figure, the erroneous assembly prevention mechanism can be inserted in the axial direction when the solenoid valve is shifted around the axis with respect to the normal assembly position. The first engagement portion and the second engagement portion may be formed so that the valve cannot be rotated around the axis. Even if the hydraulic control device 4 of the present modification is configured as described above, the same effects as those of the previous examples can be obtained.

また、誤組付け防止機構は、図示しないが、誤組付け防止の専用のものとして設けたものであってもよい。例えば、この誤組付け防止機構は、電磁弁から突出させた突出部としての第１係合部と、電磁弁が正規の組付け位置のときにだけ第１係合部が挿入される溝部としての第２係合部と、を備えており、電磁弁が正規の組付け位置以外のときに第１係合部が油圧回路体又は接続体に引っ掛かるように形成する。   Further, although not shown in the drawing, the misassembly prevention mechanism may be provided as a dedicated mechanism for preventing misassembly. For example, this erroneous assembly prevention mechanism includes a first engaging portion as a protruding portion that protrudes from the electromagnetic valve, and a groove portion into which the first engaging portion is inserted only when the electromagnetic valve is in a proper assembly position. The second engagement portion is formed so that the first engagement portion is caught by the hydraulic circuit body or the connection body when the solenoid valve is not in the normal assembly position.
