各本体部は、例えばアルミニウム等の金属のダイキャストによる部材である。
セパレートプレート４は、下側本体部１１Ｂと上側本体部１２Ｂの間に全体的に配置されたプレート４１（第１セパレートプレートの例）と、プレート４１上に接触して局所的に配置された環状プレート４２（第２セパレートプレートの例）とを含む。 As shown in FIG. 1, the hydraulic device 1 of the present embodiment has a lower main body portion 11B, an upper main body portion 12B, and a separate plate 4 arranged between the lower main body portion 11B and the upper main body portion 12B. Have.
Each main body is a die-cast member of a metal such as aluminum.
The separate plate 4 has a plate 41 (example of a first separate plate) generally arranged between the lower main body portion 11B and the upper main body portion 12B, and an annular shape locally arranged in contact with the plate 41. Includes plate 42 (example of second separate plate).

プレート４１は、例えば鉄などの平板であり、隣接する本体部の間のシーリング機能を提供する。プレート４１は、油圧装置１における油路を構成するための孔４１ｈを有する。下側本体部１１Ｂは内部に油路１１１を有しており、油路１１１の下側油路ポート１１０がプレート４１の孔４１ｈに対向する。上側本体部１２Ｂは内部に油路１２１を有しており、油路１２１の上側油路ポート１２０がプレート４１の孔４１ｈに対向する。 The plate 41 is a flat plate such as iron and provides a sealing function between adjacent main bodies. The plate 41 has a hole 41h for forming an oil passage in the hydraulic device 1. The lower main body portion 11B has an oil passage 111 inside, and the lower oil passage port 110 of the oil passage 111 faces the hole 41h of the plate 41. The upper main body portion 12B has an oil passage 121 inside, and the upper oil passage port 120 of the oil passage 121 faces the hole 41h of the plate 41.

環状プレート４２は、フィルタ部材５の密閉性を向上させるために設けられており、その材料は問わないが、例えばＰＴＦＥ（ポリテトラフルオロエチレン）等の樹脂材料が好ましい。
図２に示すように、環状プレート４２は、内周壁４２３によって画定される内孔４２ｈを備える。環状プレート４２は、内孔４２ｈがプレート４１の孔４１ｈに対向するように、プレート４１の上方に配置される。 The annular plate 42 is provided to improve the airtightness of the filter member 5, and the material thereof is not limited, but a resin material such as PTFE (polytetrafluoroethylene) is preferable.
As shown in FIG. 2, the annular plate 42 includes an inner hole 42h defined by an inner peripheral wall 423. The annular plate 42 is arranged above the plate 41 so that the inner hole 42h faces the hole 41h of the plate 41.

プレート４１の孔４１ｈと環状プレート４２の内孔４２ｈは、上側油路ポート１２０と下側油路ポート１１０を連通させるセパレートプレート４の連通孔を構成する。本実施形態では、プレート４１の孔４１ｈの径と環状プレート４２の内孔４２ｈの径が同一である場合を例示するが、その限りではない。 The hole 41h of the plate 41 and the inner hole 42h of the annular plate 42 form a communication hole of the separate plate 4 for communicating the upper oil passage port 120 and the lower oil passage port 110. In the present embodiment, the case where the diameter of the hole 41h of the plate 41 and the diameter of the inner hole 42h of the annular plate 42 are the same is illustrated, but the case is not limited to this.

図１に示すように、本実施形態の油圧装置１は、フィルタ部材５を備える。
フィルタ部材５は、油路１２１と油路１１１の間に配置され、油路１２１から油路１１１へ流れる作動油に含まれる異物を捕集するために設けられている。図１には、油圧装置１における作動油の例示的な流れＦが示されている。図３に示すように、フィルタ部材５は、軸方向一端側が開口し、軸方向他端側が有底の円筒状の部材である。 As shown in FIG. 1, the hydraulic device 1 of the present embodiment includes a filter member 5.
The filter member 5 is arranged between the oil passage 121 and the oil passage 111, and is provided for collecting foreign matter contained in the hydraulic oil flowing from the oil passage 121 to the oil passage 111. FIG. 1 shows an exemplary flow F of hydraulic oil in the hydraulic device 1. As shown in FIG. 3, the filter member 5 is a cylindrical member having an opening on one end side in the axial direction and a bottom on the other end side in the axial direction.

より具体的には、フィルタ部材５は、軸方向一端側に、開口５２ｈを有する環状部５２と、環状部５２から上方に延びており、径方向外側に張り出した凸部５５（突起部の一例）とを有する。フィルタ部材５は、軸方向他端側に底部５１と、底部５１から軸方向一端側に向かって環状部５２まで延びる柱状部５３（本実施形態の例では、４本）と、側面に取り付けられた網目状部５４とを有する。フィルタ部材５が油圧装置１に組み込まれたときには、フィルタ部材５の軸方向他端側は、軸方向一端側に対して下方向に位置する。
フィルタ部材５の網目状部５４以外の部分は、例えば樹脂材料あるいは金属材料で構成される。網目状部５４は、例えばナイロン網あるいはステンレス網で構成される。 More specifically, the filter member 5 has an annular portion 52 having an opening 52h on one end side in the axial direction, and a convex portion 55 (an example of a protrusion) extending upward from the annular portion 52 and projecting outward in the radial direction. ) And. The filter member 5 is attached to the side surface with a bottom portion 51 on the other end side in the axial direction and a columnar portion 53 (four in the example of the present embodiment) extending from the bottom portion 51 to the annular portion 52 toward one end side in the axial direction. It has a mesh-like portion 54. When the filter member 5 is incorporated in the hydraulic device 1, the other end side in the axial direction of the filter member 5 is located downward with respect to one end side in the axial direction.
The portion of the filter member 5 other than the mesh portion 54 is made of, for example, a resin material or a metal material. The mesh portion 54 is made of, for example, a nylon mesh or a stainless steel mesh.

開口５２ｈは、プレート４１の孔４１ｈおよび環状プレート４２の内孔４２ｈに対して対向し、油路１２１内の作動油がフィルタ部材５の開口５２ｈからフィルタ部材５内に導かれるように構成されている。したがって、本実施形態の油圧装置１では、フィルタ部材５内に導かれた作動油の異物は網目状部５４によって捕集され、異物が除去された作動油が油路１１１を流れる。 The opening 52h faces the hole 41h of the plate 41 and the inner hole 42h of the annular plate 42, and the hydraulic oil in the oil passage 121 is configured to be guided into the filter member 5 from the opening 52h of the filter member 5. There is. Therefore, in the hydraulic device 1 of the present embodiment, the foreign matter of the hydraulic oil guided into the filter member 5 is collected by the mesh-like portion 54, and the hydraulic oil from which the foreign matter has been removed flows through the oil passage 111.

図３および図４に示すように、フィルタ部材５の柱状部５３の外周面は、径方向外側に突出する突出部５３ｐを有する。突出部５３ｐは、軸方向に沿って緩やかに湾曲しており、後述するように、上側油路ポート１２０側から下側油路ポート１１０側に向けて拡径するテーパ面５３ｐ１を有する。突出部５３ｐは、環状部５２の近傍に設けられている。
底部５１の外径、および、４本の柱状部５３のうち対向する一対の柱状部５３の突出部５３ｐ以外の部分の最も外側の外面間の距離は、プレート４１の孔４１ｈの径よりも小さい。他方、対向する一対の柱状部５３の突出部５３ｐ間の距離の最大値は、プレート４１の孔４１ｈの径よりも大きい。本実施形態では、突出部５３ｐは、油圧装置１においてフィルタ部材５がセパレートプレート４の連通孔から離脱しないようにするために設けられている。
凸部５５は、フィルタ部材５をセパレートプレート４に対してスナップフィットにより取り付けるために設けられている。凸部５５の形態については後述する。 As shown in FIGS. 3 and 4, the outer peripheral surface of the columnar portion 53 of the filter member 5 has a protruding portion 53p protruding outward in the radial direction. The protruding portion 53p is gently curved along the axial direction, and has a tapered surface 53p1 whose diameter increases from the upper oil passage port 120 side to the lower oil passage port 110 side, as will be described later. The protruding portion 53p is provided in the vicinity of the annular portion 52.
The distance between the outer diameter of the bottom portion 51 and the outermost outer surface of the four columnar portions 53 other than the protruding portions 53p of the pair of columnar portions 53 facing each other is smaller than the diameter of the hole 41h of the plate 41. .. On the other hand, the maximum value of the distance between the protruding portions 53p of the pair of columnar portions 53 facing each other is larger than the diameter of the hole 41h of the plate 41. In the present embodiment, the protrusion 53p is provided so that the filter member 5 does not separate from the communication hole of the separate plate 4 in the hydraulic device 1.
The convex portion 55 is provided for attaching the filter member 5 to the separate plate 4 by snap-fitting. The form of the convex portion 55 will be described later.

（１－２）フィルタ部材５とセパレートプレート４の位置関係
次に、図５を参照して、フィルタ部材５とセパレートプレート４の位置関係について説明する。図５は、図４のＡ－Ａ断面を、一部を拡大して示す図である。なお、図５では、仮想的に、フィルタ部材５が組み付けられたときのセパレートプレート４を図示してある。 (1-2) Positional Relationship between Filter Member 5 and Separate Plate 4 Next, the positional relationship between the filter member 5 and the separate plate 4 will be described with reference to FIG. FIG. 5 is a partially enlarged view showing a cross section taken along the line AA of FIG. Note that FIG. 5 virtually illustrates the separate plate 4 when the filter member 5 is assembled.

図５に示すように、本実施形態の例では、凸部５５は、傾斜面５５１，５５２によって径方向外側に向かって先細りとなる形態をなしている。傾斜面５５１は、上側油路ポート１２０側から下側油路ポート１１０側に向けて外側に傾斜している。
凸部５５は、環状プレート４２の上側（上側本体部１２Ｂの側）において、環状プレート４２の内孔４２ｈの周縁４２１，４２２の外側（つまり、セパレートプレート４の連通孔の外側）に突出しており、傾斜面５５２が内孔４２ｈの周縁４２２に接触する。すなわち、凸部５５は、セパレートプレート４の上側油路ポート１２０側の表面に接触している。
図３に示したように、凸部５５は環状部５２から上向きに突出しており、プレート４１の孔４１ｈの周縁４１１，４１２の内側および環状プレート４２の内孔４２ｈの周縁４２１，４２２の内側（つまり、セパレートプレート４の連通孔の内側）まで弾性変形可能である。そのため、フィルタ部材５を凸部５５により、セパレートプレート４の連通孔にスナップフィットにより取り付けることができる。 As shown in FIG. 5, in the example of the present embodiment, the convex portion 55 has a form that is tapered toward the outside in the radial direction by the inclined surfaces 551 and 552. The inclined surface 551 is inclined outward from the upper oil passage port 120 side toward the lower oil passage port 110 side.
The convex portion 55 projects on the upper side of the annular plate 42 (on the side of the upper main body portion 12B) to the outside of the peripheral edges 421 and 422 of the inner hole 42h of the annular plate 42 (that is, the outside of the communication hole of the separate plate 4). The inclined surface 552 contacts the peripheral edge 422 of the inner hole 42h. That is, the convex portion 55 is in contact with the surface of the separate plate 4 on the upper oil passage port 120 side.
As shown in FIG. 3, the convex portion 55 projects upward from the annular portion 52, and is inside the peripheral edges 411 and 412 of the hole 41h of the plate 41 and inside the peripheral edges 421 and 422 of the inner hole 42h of the annular plate 42. That is, it can be elastically deformed up to the inside of the communication hole of the separate plate 4. Therefore, the filter member 5 can be attached to the communication hole of the separate plate 4 by snap-fitting by the convex portion 55.

他方、柱状部５３の突出部５３ｐは、プレート４１の下側油路ポート１１０側の周縁４１１に接触している。すなわち、突出部５３ｐは、プレート４１の下側油路ポート１１０側の表面に接触する。
したがって、突出部５３ｐと凸部５５によりセパレートプレート４が挟まってフィルタ部材５が保持されている。すなわち、フィルタ部材５に対して下側油路ポート１１０側の方向（図１の下方向）に力が作用した場合に、フィルタ部材５がセパレートプレート４の環状プレート４２に支持されて移動しない。フィルタ部材５に対して上側油路ポート１２０側の方向（図１の上方向）に力が作用した場合に、フィルタ部材５がセパレートプレート４のプレート４１に支持されて移動しない。 On the other hand, the protruding portion 53p of the columnar portion 53 is in contact with the peripheral edge 411 on the lower oil passage port 110 side of the plate 41. That is, the protrusion 53p comes into contact with the surface of the plate 41 on the lower oil passage port 110 side.
Therefore, the separate plate 4 is sandwiched between the protrusion 53p and the protrusion 55 to hold the filter member 5. That is, when a force acts on the filter member 5 in the direction toward the lower oil passage port 110 (downward in FIG. 1), the filter member 5 is supported by the annular plate 42 of the separate plate 4 and does not move. When a force acts on the filter member 5 in the direction toward the upper oil passage port 120 (upward in FIG. 1), the filter member 5 is supported by the plate 41 of the separate plate 4 and does not move.

（１－３）フィルタ部材５の組み付け方法
次に、図６ａ～図６ｃを参照して、フィルタ部材５を本実施形態の油圧装置１に組み付ける方法について説明する。図６ａ～図６ｃはそれぞれ、本実施形態のフィルタ部材５の組み付け手順Ｓ１～Ｓ６を示す図である。 (1-3) Assembling Method of Filter Member 5 Next, a method of assembling the filter member 5 to the hydraulic device 1 of the present embodiment will be described with reference to FIGS. 6a to 6c. 6a to 6c are diagrams showing the assembly procedures S1 to S6 of the filter member 5 of the present embodiment, respectively.

フィルタ部材５を油圧装置に組み付けるには先ず、図６ａのＳ１，Ｓ２に示すように、フィルタ部材５とプレート４１を図１に示した状態とは反対向きにし、フィルタ部材５を開口側からプレート４１に取り付ける。このとき、フィルタ部材５の凸部５５がスナップフィットによりプレート４１の孔４１ｈの周縁に嵌合する。すなわち、作業者がフィルタ部材５を押し下げることで、４箇所の凸部５５が径方向内側に弾性変形して孔４１ｈを通過し、孔４１ｈを通過した後は凸部５５の弾性変形が解消することで、凸部５５が孔４１ｈの周縁に嵌合する。なお、嵌合した後は、対向する一対の突出部５３ｐ間の距離の最大値がプレート４１の孔４１ｈの径よりも大きいため、作業者がフィルタ部材５から手を離してもフィルタ部材５が自重により孔４１ｈから脱落することはない。
仮に、フィルタ部材５を底部から孔４１ｈに挿入する作業をしたならば、孔４１ｈに突出部５３ｐを通過させるという力作業を行わなくてはならないが、本実施形態では、フィルタ部材５の開口側からスナップフィットによって取り付けることで作業性が高いという利点がある。 To assemble the filter member 5 to the hydraulic device, first, as shown in S1 and S2 of FIG. 6a, the filter member 5 and the plate 41 are oriented in the opposite directions to those shown in FIG. Attach to 41. At this time, the convex portion 55 of the filter member 5 is fitted to the peripheral edge of the hole 41h of the plate 41 by snap fitting. That is, when the operator pushes down the filter member 5, the four convex portions 55 elastically deform inward in the radial direction and pass through the hole 41h, and after passing through the hole 41h, the elastic deformation of the convex portion 55 disappears. As a result, the convex portion 55 fits into the peripheral edge of the hole 41h. After mating, the maximum value of the distance between the pair of protruding portions 53p facing each other is larger than the diameter of the hole 41h of the plate 41, so that even if the operator releases his hand from the filter member 5, the filter member 5 It does not fall out of the hole 41h due to its own weight.
If the work of inserting the filter member 5 into the hole 41h from the bottom is performed, the force work of passing the protrusion 53p through the hole 41h must be performed, but in the present embodiment, the opening side of the filter member 5 must be performed. There is an advantage that workability is high by attaching by snap fit.

次に、図６ｂのＳ３，Ｓ４に示すように、フィルタ部材５とプレート４１を一体化させたワークをひっくり返し、上から環状プレート４２をフィルタ部材５にスナップフィットにより取り付ける。
すなわち、作業者が環状プレート４２をフィルタ部材５の凸部５５に上から押し込むことで４箇所の凸部５５が径方向内側に弾性変形する。このとき、凸部５５の傾斜面５５１が開口から底部に向けて（つまり、図１の上側油路ポート１２０から下側油路ポート１１０に向けて）外側に傾斜している。そのため、環状プレート４２を傾斜面５５１に押し当てたときに、傾斜面５５１に径方向内側に向く分力が生じるため、凸部５５を径方向内側に弾性変形させやすくなっている。 Next, as shown in S3 and S4 of FIG. 6b, the work in which the filter member 5 and the plate 41 are integrated is turned over, and the annular plate 42 is attached to the filter member 5 by snap-fit from above.
That is, when the operator pushes the annular plate 42 into the convex portion 55 of the filter member 5 from above, the four convex portions 55 are elastically deformed inward in the radial direction. At this time, the inclined surface 551 of the convex portion 55 is inclined outward from the opening toward the bottom (that is, from the upper oil passage port 120 to the lower oil passage port 110 in FIG. 1). Therefore, when the annular plate 42 is pressed against the inclined surface 551, a component force is generated in the inclined surface 551 inward in the radial direction, so that the convex portion 55 is easily elastically deformed inward in the radial direction.

さらに環状プレート４２を押し込んでいくと、環状プレート４２が凸部５５の下方に配置されるプレート４１に接触する位置まで進み停止する。環状プレート４２が凸部５５を通過してプレート４１に接触する位置まで達すると、凸部５５の弾性変形が解消され、図５に示したように、凸部５５の傾斜面５５２が環状プレート４２の表面に接触した状態（図６ｂのＳ４の状態）となる。この状態では、フィルタ部材５は、突出部５３ｐと凸部５５によりセパレートプレート４を挟むようになっており、セパレートプレート４から離脱しない。 When the annular plate 42 is further pushed in, the annular plate 42 advances to a position where it contacts the plate 41 arranged below the convex portion 55 and stops. When the annular plate 42 passes through the convex portion 55 and reaches a position where it comes into contact with the plate 41, the elastic deformation of the convex portion 55 is eliminated, and as shown in FIG. 5, the inclined surface 552 of the convex portion 55 becomes the annular plate 42. It is in contact with the surface of (S4 in FIG. 6b). In this state, the filter member 5 sandwiches the separate plate 4 by the protruding portion 53p and the convex portion 55, and does not separate from the separate plate 4.

次いで、図６ｃのＳ５，Ｓ６に示すように、水平面に下側本体部１１Ｂを配置し、フィルタ部材５とセパレートプレート４を一体化させたワークを、下側本体部１１Ｂの上にプレート４１を位置決めしながら配置する。その後、上側本体部１２Ｂをプレート４１上に配置することで、フィルタ部材５の組み付けが完了する。 Next, as shown in S5 and S6 of FIG. 6c, the lower main body portion 11B is arranged on a horizontal plane, the work in which the filter member 5 and the separate plate 4 are integrated, and the plate 41 is placed on the lower main body portion 11B. Place while positioning. After that, by arranging the upper main body portion 12B on the plate 41, the assembly of the filter member 5 is completed.

以上の手順により、上側本体部１２Ｂを配置させる作業、あるいは図６ｂのＳ４に示した状態のワークを工程内で移動させる作業を行うときに、フィルタ部材５がセパレートプレート４から脱落することがないため、組み付け作業性が向上する。 By the above procedure, the filter member 5 does not fall off from the separate plate 4 when the work of arranging the upper main body portion 12B or the work of moving the work in the state shown in S4 of FIG. 6b in the process. Therefore, the assembly workability is improved.

なお、本実施形態では、突出部５３ｐは、上側油路ポート１２０側から下側油路ポート１１０側に向けて拡径するテーパ面５３ｐ１を有するため、突出部５３ｐがプレート４１の孔４１ｈの周縁４１１（図５参照）に周方向の全域で接触する。そのため、フィルタ部材５の軸が鉛直方向に対して傾き難くなり、特に図６ｂのＳ３，Ｓ４において安定した作業が可能となる。 In the present embodiment, since the protruding portion 53p has a tapered surface 53p1 whose diameter increases from the upper oil passage port 120 side to the lower oil passage port 110 side, the protruding portion 53p is the peripheral edge of the hole 41h of the plate 41. It contacts 411 (see FIG. 5) over the entire circumferential direction. Therefore, the axis of the filter member 5 is less likely to be tilted in the vertical direction, and stable work is possible especially in S3 and S4 of FIG. 6b.

（２）第２の実施形態
次に、本発明の第２の実施形態に係るフィルタ部材５Ａについて、図７を参照して説明する。図７は、第２の実施形態のフィルタ部材５Ａの断面を、一部を拡大して示す図である。当該断面は、フィルタ部材５Ａを図４のＡ－Ａと同様の位置で切断したものである。
なお、以下の説明では、第１の実施形態に係るフィルタ部材５との相違点に焦点を当てて説明し、図７では、第１の実施形態で言及した構成部品、部位と同一のものについては同一符号を付し、以下では重複説明を省く。 (2) Second Embodiment Next, the filter member 5A according to the second embodiment of the present invention will be described with reference to FIG. 7. FIG. 7 is a partially enlarged view showing a cross section of the filter member 5A of the second embodiment. The cross section is obtained by cutting the filter member 5A at the same position as AA in FIG.
In the following description, the differences from the filter member 5 according to the first embodiment will be focused on, and in FIG. 7, the same components and parts as those mentioned in the first embodiment will be described. Have the same reference numerals, and duplicate explanations will be omitted below.

第１の実施形態のフィルタ部材５は、スナップフィットによりセパレートプレート４に取り付けられるのに対して、本実施形態のフィルタ部材５Ａは、ねじ締結によりセパレートプレート４に取り付けられる点で第１の実施形態と相違する。
具体的には、図７に示すように、本実施形態のフィルタ部材５Ａの柱状部５３Ａは、凸部５５に代えて、全周にねじ切り部５６を有する。なお、ねじ切り部５６は必ずしも全周に設けなくてもよく、周上の一部であってもよい。
本実施形態の環状プレート４２Ａは、ねじ切り部を備えた内周壁４２３Ａを有する。フィルタ部材５Ａのねじ切り部５６と内周壁４２３Ａのねじ切り部とが締結されている。 The filter member 5 of the first embodiment is attached to the separate plate 4 by snap-fitting, whereas the filter member 5A of the present embodiment is attached to the separate plate 4 by screw fastening. Is different from.
Specifically, as shown in FIG. 7, the columnar portion 53A of the filter member 5A of the present embodiment has a thread cutting portion 56 on the entire circumference instead of the convex portion 55. The threaded portion 56 does not necessarily have to be provided on the entire circumference, and may be a part of the circumference.
The annular plate 42A of the present embodiment has an inner peripheral wall 423A provided with a threaded portion. The threaded portion 56 of the filter member 5A and the threaded portion of the inner peripheral wall 423A are fastened.

本実施形態のフィルタ部材５Ａの組み付け方法は、以下のとおりである。
先ず、図６ａのＳ１，Ｓ２に示したのと同様に、フィルタ部材５Ａを開口側からプレート４１に取り付ける。本実施形態では、フィルタ部材５Ａのねじ切り部５６の外径はプレート４１の孔４１ｈの径よりも小さくなっており、フィルタ部材５Ａのねじ切り部５６は孔４１ｈを難なく通過する。そのため、図６ａのＳ１，Ｓ２とは異なり、図１に示した状態とは反対向きにしなくても作業は容易である。
次に、図６ｂのＳ３，Ｓ４に示したのと同様に、環状プレート４２Ａの内周壁４２３Ａのねじ切り部をフィルタ部材５Ａのねじ切り部５６にねじ込むようにして上から嵌合させる。環状プレート４２Ａの下面がプレート４１の表面に接触することで、セパレートプレート４Ａとフィルタ部材５Ａが一体化したワーク（図６ｂのＳ４と同様の状態のワーク）が得られる。
次いで、図６ｃのＳ５，Ｓ６に示したのと同様に、水平面に下側本体部１１Ｂを配置し、フィルタ部材５Ａとセパレートプレート４Ａを一体化させたワークを、下側本体部１１Ｂの上にプレート４１を位置決めしながら配置する。その後、上側本体部１２Ｂをプレート４１上に配置することで、フィルタ部材５Ａの組み付けが完了する。
本実施形態においても、フィルタ部材５Ａがセパレートプレート４Ａから脱落することがないため、組み付け作業性が向上する。 The method of assembling the filter member 5A of the present embodiment is as follows.
First, the filter member 5A is attached to the plate 41 from the opening side in the same manner as shown in S1 and S2 of FIG. 6a. In the present embodiment, the outer diameter of the threaded portion 56 of the filter member 5A is smaller than the diameter of the hole 41h of the plate 41, and the threaded portion 56 of the filter member 5A passes through the hole 41h without difficulty. Therefore, unlike S1 and S2 of FIG. 6a, the work is easy even if the orientation is not opposite to that shown in FIG.
Next, in the same manner as shown in S3 and S4 of FIG. 6b, the threaded portion of the inner peripheral wall 423A of the annular plate 42A is screwed into the threaded portion 56 of the filter member 5A and fitted from above. When the lower surface of the annular plate 42A comes into contact with the surface of the plate 41, a work in which the separate plate 4A and the filter member 5A are integrated (a work in the same state as S4 in FIG. 6b) can be obtained.
Next, in the same manner as shown in S5 and S6 of FIG. 6c, the lower main body portion 11B is arranged on a horizontal plane, and the work in which the filter member 5A and the separate plate 4A are integrated is placed on the lower main body portion 11B. The plate 41 is arranged while being positioned. After that, by arranging the upper main body portion 12B on the plate 41, the assembly of the filter member 5A is completed.
Also in this embodiment, since the filter member 5A does not fall off from the separate plate 4A, the assembling workability is improved.

以上、本発明の実施形態について詳細に説明したが、本発明の範囲は上記の実施形態に限定されない。また、上記の実施形態は、本発明の主旨を逸脱しない範囲において、種々の改良や変更が可能である。 Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited to the above embodiments. Further, the above-described embodiment can be variously improved or modified without departing from the gist of the present invention.

第１の実施形態では、プレート４１および環状プレート４２によりセパレートプレート４を構成したが、環状プレート４２は必須ではない。
環状プレート４２は、フィルタ部材５の径方向外側の外面とプレート４１の孔４１ｈの隙間の密閉性を高めて、当該隙間を通して異物が油路１２１から油路１１１に向けて移動することを抑制するために設けられている。そのため、プレート４１の孔４１ｈとフィルタ部材５の間で十分に密閉性が確保できれば、環状プレート４２を設けなくてもよい。
図５を参照すると、環状プレート４２を設けない実施形態では、フィルタ部材５は、凸部５５の傾斜面５５２がプレート４１の孔４１ｈの周縁４２１（すなわち、プレート４１の表面）に接触するようにして構成される。 In the first embodiment, the separate plate 4 is composed of the plate 41 and the annular plate 42, but the annular plate 42 is not essential.
The annular plate 42 enhances the airtightness of the gap between the outer outer surface of the filter member 5 in the radial direction and the hole 41h of the plate 41, and suppresses foreign matter from moving from the oil passage 121 to the oil passage 111 through the gap. It is provided for the purpose. Therefore, if sufficient airtightness can be ensured between the hole 41h of the plate 41 and the filter member 5, the annular plate 42 may not be provided.
Referring to FIG. 5, in the embodiment in which the annular plate 42 is not provided, the filter member 5 has the inclined surface 552 of the convex portion 55 in contact with the peripheral edge 421 (that is, the surface of the plate 41) of the hole 41h of the plate 41. It is composed of.

第１の実施形態では、凸部５５の傾斜面５５２が環状プレート４２の周縁４２２に接触することで、凸部５５がセパレートプレート４の上側油路ポート１２０側の表面に接触する例を示したが、その限りではない。凸部５５の形態を例えば楔形に変更することで、環状プレート４２の周縁４２２以外の表面に接触させるようにしてもよい。例えば、斜め下方に向く楔形の凸部５５の最も先細りした部分を、周縁４２２以外の環状プレート４２の表面に接触させるようにしてもよい。
同様にして、環状プレート４２を設けない実施形態では、凸部５５をプレート４１の周縁４１２以外のプレート４１の表面に接触させるようにすることもできる。 In the first embodiment, an example is shown in which the inclined surface 552 of the convex portion 55 contacts the peripheral edge 422 of the annular plate 42, so that the convex portion 55 contacts the surface of the separate plate 4 on the upper oil passage port 120 side. However, this is not the case. By changing the shape of the convex portion 55 to, for example, a wedge shape, the annular plate 42 may be brought into contact with a surface other than the peripheral edge 422. For example, the most tapered portion of the wedge-shaped convex portion 55 facing diagonally downward may be brought into contact with the surface of the annular plate 42 other than the peripheral edge 422.
Similarly, in the embodiment in which the annular plate 42 is not provided, the convex portion 55 may be brought into contact with the surface of the plate 41 other than the peripheral edge 412 of the plate 41.

各実施形態において、フィルタ部材５，５Ａの柱状部５３，５３Ａに突出部５３ｐを設けることは必須ではない。例えば第１の実施形態において、図６ａ，図６ｂのＳ１～Ｓ３では、作業者がフィルタ部材５の側部を保持しながらワークをひっくり返すことで、突出部５３ｐを設けない場合であっても、フィルタ部材５のプレート４１からの離脱を防止することができる。図６ｂのＳ３の状態のワークでは、凸部５５が孔４１ｈの周縁に引っ掛かっているため、下方向に脱落しない。
しかし、ワークのハンドリングの自由度や、フィルタ部材の組み付け時の作業の自由度を高める観点から、突出部５３ｐを設ける利点がある。すなわち、突出部５３ｐを設けることにより、Ｓ２の状態のワークにおいて作業者がフィルタ部材５を保持しなくてもフィルタ部材５のプレート４１からの脱落が防止でき、また、Ｓ４の状態のワークをハンドリング中や工程内に移送中にひっくり返した場合でもフィルタ部材５の脱落を防止できる。
第２の実施形態では、図６ｂのＳ３において作業者が、フィルタ部材５を保持しつつ環状プレート４２Ａのねじ切り部をフィルタ部材５のねじ切り部５６に嵌合させる作業を行うことで、突出部５３ｐがなくてもＳ４に示すワークを作製することが可能である。しかし、突出部５３ｐを設けることで下方向に脱落する可能性がなくなるため、環状プレート４２Ａを取り付ける際にフィルタ部材５を保持しなくても済み、作業が容易になるという利点がある。 In each embodiment, it is not essential to provide the projecting portions 53p on the columnar portions 53, 53A of the filter members 5, 5A. For example, in the first embodiment, in S1 to S3 of FIGS. 6a and 6b, even when the worker turns over the work while holding the side portion of the filter member 5, the protruding portion 53p is not provided. It is possible to prevent the filter member 5 from coming off from the plate 41. In the work in the state of S3 in FIG. 6b, since the convex portion 55 is caught on the peripheral edge of the hole 41h, it does not fall off downward.
However, there is an advantage that the protrusion 53p is provided from the viewpoint of increasing the degree of freedom in handling the work and the degree of freedom in the work when assembling the filter member. That is, by providing the protruding portion 53p, it is possible to prevent the filter member 5 from falling off from the plate 41 even if the operator does not hold the filter member 5 in the work in the state of S2, and the work in the state of S4 is handled. It is possible to prevent the filter member 5 from falling off even if it is turned over during transfer during the process or during the process.
In the second embodiment, in S3 of FIG. 6b, the operator performs the work of fitting the threaded portion of the annular plate 42A to the threaded portion 56 of the filter member 5 while holding the filter member 5, so that the protruding portion 53p is performed. It is possible to produce the work shown in S4 even if there is no such work. However, since there is no possibility that the protruding portion 53p will fall off in the downward direction, there is an advantage that the filter member 5 does not have to be held when the annular plate 42A is attached, which facilitates the work.

上述した各実施形態では、フィルタ部材５，５Ａが円筒状である場合について説明したが、その限りではない。すなわち、フィルタ部材の断面は円形である場合に限られず、楕円形やハニカム状であってもよい。 In each of the above-described embodiments, the case where the filter members 5 and 5A have a cylindrical shape has been described, but the present invention is not limited to this. That is, the cross section of the filter member is not limited to a circular shape, and may be an elliptical shape or a honeycomb shape.
