［実施形態］
本発明に係るダイヤルスイッチ及び車載機器操作システムの実施形態の１つを図１から図１０に基づいて説明する。 [Embodiment]
One embodiment of a dial switch and an in-vehicle device operation system according to the present invention will be described with reference to FIGS.

図１から図６の符号１は、本実施形態のダイヤルスイッチを示す。このダイヤルスイッチ１は、回転軸の軸周りに回転操作される回転操作子１０を備える。   1 indicates a dial switch according to the present embodiment. The dial switch 1 includes a rotary operator 10 that is rotated around an axis of rotation.

回転操作子１０は、両端を開口させた円筒部１１ａ及び当該円筒部１１ａの一端の開口を塞ぐ円板状の閉塞部１１ｂを有する主体１１と、その円筒部１１ａの他端の開口を塞ぐ円板状の閉塞体１２と、を備える（図１から図４）。この回転操作子１０は、閉塞体１２を円筒部１１ａの他端の開口に嵌合固定することによって、ダイヤル操作部材として形成される。この回転操作子１０においては、その内方の空間を後述する操作形態検出具２０の磁石２１の収容室１３として利用する（図３）。この例示の回転操作子１０は、合成樹脂等の絶縁性材料で成形する。   The rotary operation element 10 includes a main body 11 having a cylindrical portion 11a having both ends opened and a disk-shaped closing portion 11b closing one end of the cylindrical portion 11a, and a circle closing the other end of the cylindrical portion 11a. And a plate-shaped closing body 12 (FIGS. 1 to 4). The rotary operation member 10 is formed as a dial operation member by fitting and closing the closing body 12 to the opening at the other end of the cylindrical portion 11a. In the rotary operation element 10, the space inside the rotation operation element 10 is used as a storage chamber 13 for a magnet 21 of an operation mode detection tool 20 described later (FIG. 3). The example rotary operator 10 is formed of an insulating material such as a synthetic resin.

この回転操作子１０においては、操作者が手指で回転操作する際の接触操作部として、円筒部１１ａの外周壁１１ｃを利用する（図１から図６）。その外周壁１１ｃは、回転操作する際の手指の滑りを抑えるべく凹凸が形成されている。この例示の外周壁１１ｃにおいては、周方向で等間隔に複数の凹部と凸部とが交互に並べられている。   In the rotary operation device 10, an outer peripheral wall 11c of a cylindrical portion 11a is used as a contact operation portion when an operator performs a rotation operation with a finger (FIGS. 1 to 6). The outer peripheral wall 11c is formed with irregularities so as to suppress slippage of fingers during a rotation operation. In the illustrated outer peripheral wall 11c, a plurality of concave portions and convex portions are alternately arranged at equal intervals in the circumferential direction.

この回転操作子１０は、回転軸と一体になって回転するものであってもよく、回転軸に対して軸周りに相対回転するものであってもよい。この例示の回転操作子１０は、回転軸１４（図３及び図４）と一体になって回転させる。ここでは、回転操作子１０とは別の部品として円柱状の回転軸１４を成形し、閉塞部１１ｂの軸心の円形の貫通孔１１ｄと閉塞体１２の軸心の円形の貫通孔１２ａ（図３及び図４）とに回転軸１４を挿通させる。回転操作子１０と回転軸１４との間には、これら相互間の軸周りの相対回転を抑えるための回転抑止機構１５を設けている（図３、図４及び図７）。   The rotary operator 10 may rotate integrally with the rotary shaft, or may rotate relative to the rotary shaft around the axis. The example rotary operator 10 is rotated integrally with a rotary shaft 14 (FIGS. 3 and 4). Here, a cylindrical rotary shaft 14 is formed as a separate component from the rotary operator 10, and a circular through hole 11d having an axial center of the closing portion 11b and a circular through hole 12a having an axial center of the closing body 12 (see FIG. 3 and FIG. 4). Between the rotary operator 10 and the rotary shaft 14, there is provided a rotation suppressing mechanism 15 for suppressing relative rotation about the mutual axis (FIGS. 3, 4 and 7).

回転抑止機構１５は、例えば、回転操作子１０と回転軸１４の内の一方に設けたキー溝部１５ａ（図７）と、その内の他方に設けたキー部１５ｂ（図３及び図４）と、を有する。この回転抑止機構１５は、回転操作子１０と回転軸１４との間に少なくとも一組み設ける。この例示では、キー溝部１５ａを回転操作子１０に設け、キー部１５ｂを回転軸１４に設ける。また、この例示では、回転抑止機構１５を２箇所に設ける。   The rotation suppressing mechanism 15 includes, for example, a key groove portion 15a (FIG. 7) provided on one of the rotation operator 10 and the rotation shaft 14, and a key portion 15b (FIGS. 3 and 4) provided on the other of the rotation operator 10 and the rotation shaft 14. And At least one set of the rotation suppressing mechanism 15 is provided between the rotation operator 10 and the rotation shaft 14. In this example, the key groove 15 a is provided on the rotary operator 10, and the key 15 b is provided on the rotary shaft 14. In this example, the rotation suppressing mechanism 15 is provided at two positions.

この例示の回転操作子１０は、閉塞部１１ｂの貫通孔１１ｄの周縁から収容室１３側に垂設させた壁部１１ｆを２つ有している（図３及び図７）。それぞれの壁部１１ｆは、貫通孔１１ｄの周縁において、貫通孔１１ｄの周方向における互いの端部同士の間に隙間が形成されるように、この貫通孔１１ｄの軸線方向に対する直交方向で対向配置する。この回転操作子１０においては、その２つの隙間をキー溝部１５ａとして利用する（図７）。また、回転軸１４は、外周面から径方向の外側に突出させたキー部１５ｂを周方向で２箇所に有する（図３及び図４）。この回転抑止機構１５は、それぞれのキー部１５ｂをそれぞれのキー溝部１５ａに挿入させることによって、回転操作子１０と回転軸１４とを一体になって回転させる。   The illustrated rotary operation element 10 has two wall portions 11f vertically extending from the periphery of the through hole 11d of the closing portion 11b toward the storage chamber 13 (FIGS. 3 and 7). The walls 11f are opposed to each other in a direction perpendicular to the axial direction of the through-hole 11d so that a gap is formed between the ends of the through-hole 11d in the circumferential direction at the periphery of the through-hole 11d. I do. In the rotary operation element 10, the two gaps are used as the key groove 15a (FIG. 7). Further, the rotating shaft 14 has key portions 15b projecting radially outward from the outer peripheral surface at two positions in the circumferential direction (FIGS. 3 and 4). The rotation suppressing mechanism 15 rotates the rotary operator 10 and the rotary shaft 14 integrally by inserting the respective key portions 15b into the respective key groove portions 15a.

このダイヤルスイッチ１には、回転操作子１０の軸周りの回転変位を検出し、その回転変位に応じた信号を出力する操作形態検出具２０が設けられている（図１から図４）。この例示の操作形態検出具２０としては、磁気型のロータリエンコーダを用いる。この操作形態検出具２０は、回転操作子１０と同心の円環状の磁石２１と、ホール素子（図示略）と、を備える（図３及び図４）。ホール素子は、回路基板２２に対して物理的且つ電気的に接続される。磁石２１は、回転操作子１０の収容室１３に収容する。回路基板２２のホール素子は、磁石２１の外周面に対して間隔を空けて対向配置させる。この操作形態検出具２０においては、回転操作子１０の軸周りの回転変位を磁石２１とホール素子とで検出し、その回転変位に応じた信号を回路基板２２から操作対象機器の制御装置に送信する。   The dial switch 1 is provided with an operation form detector 20 that detects a rotational displacement of the rotary operation element 10 around the axis and outputs a signal corresponding to the rotational displacement (FIGS. 1 to 4). A magnetic rotary encoder is used as the operation mode detector 20 in this example. The operation mode detector 20 includes an annular magnet 21 concentric with the rotary operator 10 and a Hall element (not shown) (FIGS. 3 and 4). The Hall element is physically and electrically connected to the circuit board 22. The magnet 21 is housed in the housing chamber 13 of the rotary operator 10. The Hall element of the circuit board 22 is opposed to the outer peripheral surface of the magnet 21 at an interval. In the operation mode detector 20, the rotational displacement of the rotary operation element 10 around the axis is detected by the magnet 21 and the Hall element, and a signal corresponding to the rotational displacement is transmitted from the circuit board 22 to the control device of the operation target device. I do.

更に、このダイヤルスイッチ１は、回転操作子１０を軸周りの相対回転が可能な状態で保持する保持具３０を備える（図１から図４）。   Further, the dial switch 1 includes a holder 30 for holding the rotary operation member 10 in a state where relative rotation around the axis is possible (FIGS. 1 to 4).

保持具３０は、合成樹脂等の絶縁性材料で成形する。この例示の保持具３０には、回転操作子１０を収容する収容具としての機能も持たせる。この例示の保持具３０は、角筒状に成形し、その内方の空間を回転操作子１０の収容室３０ａとして利用する（図３及び図４）。この保持具３０は、その収容室３０ａにおける筒軸方向の一端から外周壁１１ｃの一部を突出させた状態で、この収容室３０ａに回転操作子１０を収容する。   The holder 30 is formed of an insulating material such as a synthetic resin. The holding tool 30 in this example also has a function as a storage tool for storing the rotary operation element 10. The holding tool 30 of this example is formed in a rectangular tube shape, and a space inside the holding tool 30 is used as a storage chamber 30a of the rotary operator 10 (FIGS. 3 and 4). The holder 30 accommodates the rotary operator 10 in the accommodation room 30a in a state where a part of the outer peripheral wall 11c protrudes from one end of the accommodation room 30a in the cylinder axis direction.

この保持具３０は、対向配置された第１及び第２の壁部３１，３２を有する（図１、図３及び図４）。この保持具３０は、第１壁部３１を回転操作子１０の閉塞体１２に回転軸１４の軸線方向で対向配置させ、かつ、第２壁部３２を回転操作子１０の閉塞部１１ｂに回転軸１４の軸線方向で対向配置させることによって、その第１及び第２の壁部３１，３２で回転操作子１０の閉塞体１２と閉塞部１１ｂとを挟み込む。   The holder 30 has first and second wall portions 31 and 32 that are opposed to each other (FIGS. 1, 3, and 4). The holder 30 is configured such that the first wall portion 31 is disposed so as to face the closing body 12 of the rotary operator 10 in the axial direction of the rotary shaft 14, and the second wall portion 32 is rotated by the closing portion 11 b of the rotary operator 10. By opposing the shaft 14 in the axial direction, the first and second walls 31 and 32 sandwich the closing body 12 and the closing portion 11b of the rotary operator 10.

第１及び第２の壁部３１，３２は、各々、回転軸１４を挿通させる円形の貫通孔３１ａ，３２ａを有する（図３及び図４）。このダイヤルスイッチ１においては、収容室３０ａに回転操作子１０を収容した状態で、例えば、第１壁部３１の貫通孔３１ａ、閉塞体１２の貫通孔１２ａ、閉塞部１１ｂの貫通孔１１ｄ、第２壁部３２の貫通孔３２ａの順に、回転軸１４を挿入していく。回転軸１４は、その第１及び第２の壁部３１，３２の貫通孔３１ａ，３２ａに軸支させることによって、第１及び第２の壁部３１，３２に対して軸周りに相対回転させる。これにより、保持具３０は、収容室３０ａの中で、回転操作子１０を軸周りに相対回転させることができる。   The first and second wall portions 31 and 32 have circular through holes 31a and 32a, respectively, through which the rotating shaft 14 is inserted (FIGS. 3 and 4). In the dial switch 1, in a state where the rotary operation element 10 is housed in the housing chamber 30 a, for example, the through hole 31 a of the first wall portion 31, the through hole 12 a of the closing body 12, the through hole 11 d of the closing portion 11 b, The rotating shaft 14 is inserted in the order of the through holes 32a of the two wall portions 32. The rotating shaft 14 is relatively rotated around the axis with respect to the first and second wall portions 31 and 32 by being pivotally supported by the through holes 31a and 32a of the first and second wall portions 31 and 32. . Thereby, the holder 30 can relatively rotate the rotary operator 10 around the axis in the storage chamber 30a.

ここで、回転軸１４においては、一方の端部を第１壁部３１から突出させ、他方の端部を第２壁部３２から突出させる。回転軸１４の一方の端部には、後述する被係止具４１を設けている。このダイヤルスイッチ１においては、この回転軸１４を第１及び第２の壁部３１，３２の貫通孔３１ａ，３２ａから抜け出させないように、この回転軸１４の他方の端部にスナップリング等の軸用留め具１６を取り付ける（図３及び図４）。このダイヤルスイッチ１では、被係止具４１と軸用留め具１６とで第１及び第２の壁部３１，３２を外側から挟み込むことによって、貫通孔３１ａ，３２ａからの回転軸１４の脱離を防ぐ。   Here, in the rotating shaft 14, one end protrudes from the first wall 31 and the other end protrudes from the second wall 32. At one end of the rotating shaft 14, a locked member 41 described later is provided. In the dial switch 1, a shaft such as a snap ring is attached to the other end of the rotary shaft 14 so that the rotary shaft 14 does not come out of the through holes 31 a and 32 a of the first and second wall portions 31 and 32. Attachment 16 is attached (FIGS. 3 and 4). In this dial switch 1, the first and second wall portions 31 and 32 are sandwiched between the locked member 41 and the shaft fastener 16 from outside, so that the rotating shaft 14 is detached from the through holes 31 a and 32 a. prevent.

The rotation locking mechanism 40 locks the rotation of the rotary operator 10 when the rotary torque of the rotary operator 10 is equal to or less than the first reference torque, and the second reference torque whose rotation torque is larger than the first reference torque. In the above case, the rotation operator 10 is configured to be allowed to rotate.

Tool 42 (FIGS. 1 to 3). The rotation locking mechanism 40 is provided outside the rotary operation element 10. The rotation locking mechanism 40 may be disposed in the storage chamber 30a of the holder 30, or may be disposed outside the storage chamber 30a. In this example, the rotation locking mechanism 40 is provided outside the accommodation room 30a.

この例示の被係止具４１と係止具４２は、従来のように金属を用いずに、合成樹脂等の絶縁性材料で成形する。従って、この例示のダイヤルスイッチ１は、先に示したように、操作形態検出具２０として磁気型のロータリエンコーダを用いているが、この操作形態検出具２０の動作に悪影響を与えない。   The locked member 41 and the locking member 42 in this example are formed of an insulating material such as a synthetic resin without using metal as in the related art. Therefore, in the illustrated dial switch 1, as described above, the magnetic rotary encoder is used as the operation mode detector 20, but the operation of the operation mode detector 20 is not adversely affected.

被係止具４１は、回転軸１４の一方の端部に設ける。この例示の被係止具４１は、収容室３０ａの外で回転軸１４の一方の端部に設けている。この被係止具４１は、回転軸１４と共に一体成形されたものであってもよく、回転軸１４とは別の部品として成形した上で、この回転軸１４の一方の端部に固定するものであってもよい。   The locked member 41 is provided at one end of the rotating shaft 14. The illustrated locked member 41 is provided at one end of the rotating shaft 14 outside the storage chamber 30a. The locked member 41 may be formed integrally with the rotating shaft 14, or may be formed as a separate component from the rotating shaft 14 and then fixed to one end of the rotating shaft 14. It may be.

被係止具４１は、平板状に形成し、その平面に対する直交方向が回転軸１４の軸線方向となるように回転軸１４の一方の端部に設ける。この被係止具４１の外周面側には、回転軸１４に対する径方向の外側に突出させた凸部４１ａと、その径方向の内側に凹ませた凹部４１ｂと、を回転軸１４の軸周りに沿って交互に複数設ける（図１、図２及び図８）。   The locked member 41 is formed in a flat plate shape, and is provided at one end of the rotating shaft 14 such that a direction orthogonal to the plane is the axial direction of the rotating shaft 14. On the outer peripheral surface side of the locked member 41, a convex portion 41a protruding outward in the radial direction with respect to the rotary shaft 14 and a concave portion 41b concaved inward in the radial direction are provided around the axis of the rotary shaft 14. Are provided alternately along the line (FIGS. 1, 2 and 8).

その凸部４１ａと凹部４１ｂは、各々、その軸周りの全周に亘って複数設けている。複数の凸部４１ａは、それぞれが全て同じ形状のものであってもよく、異なる形状のものを混在させたものであってもよい。また、複数の凹部４１ｂは、それぞれが全て同じ形状のものであってもよく、異なる形状のものを混在させたものであってもよい。更に、複数の凸部４１ａは、隣り合うもの同士を回転軸１４の軸周りに沿って同一ピッチで配置してもよく、異なるピッチのものを混在させてもよい。また、複数の凹部４１ｂは、隣り合うもの同士を回転軸１４の軸周りに沿って同一ピッチで配置してもよく、異なるピッチのものを混在させてもよい。   A plurality of convex portions 41a and concave portions 41b are provided over the entire circumference around the axis. Each of the plurality of convex portions 41a may have the same shape, or may have a mixture of different shapes. Further, each of the plurality of concave portions 41b may have the same shape, or may have a mixture of different shapes. Further, the plurality of convex portions 41a may be arranged at the same pitch along the circumference of the rotary shaft 14 adjacent to each other, or may be mixed at different pitches. In addition, the plurality of recesses 41b may be arranged at the same pitch along the circumference of the rotating shaft 14 adjacent to each other, or may be mixed at different pitches.

この例示の複数の凸部４１ａは、回転軸１４と同心の第１基準円Ｃ１上に山の頂点部が配置されるように形成し、それぞれを回転軸１４の軸周りに沿って同一ピッチで配置する（図８）。それぞれの凸部４１ａは、係止具４２との間での摩擦抵抗を軽減させるため、山の頂点部の壁面を両脇の凹部４１ｂの壁面に連なる弧状に形成している。また、この例示の複数の凹部４１ｂは、回転軸１４と同心の第２基準円Ｃ２上に谷の底部が配置されるように形成し、それぞれを回転軸１４の軸周りに沿って同一ピッチで配置する（図８）。   The plurality of convex portions 41a in this example are formed such that the vertices of the ridges are arranged on the first reference circle C1 concentric with the rotating shaft 14, and are respectively formed at the same pitch along the circumference of the rotating shaft 14. (FIG. 8). In order to reduce the frictional resistance between the projections 41a and the locking members 42, the wall surfaces at the peaks of the hills are formed in an arc shape that is continuous with the wall surfaces of the concave portions 41b on both sides. In addition, the plurality of concave portions 41b in this example are formed such that the bottoms of the valleys are arranged on the second reference circle C2 concentric with the rotating shaft 14, and are respectively formed at the same pitch around the axis of the rotating shaft 14. (FIG. 8).

係止具４２は、係止体４２ａと被支持体４２ｂとを有する（図１及び図２）。この係止具４２においては、係止体４２ａの対向配置されたそれぞれの端部４２ａ_１，４２ａ_２側に被支持体４２ｂを配置する（図１及び図２）。 The locking member 42 has a locking body 42a and a supported body 42b (FIGS. 1 and 2). In the locking member 42, a supported member 42b is disposed on each of the opposed end portions 42a ₁ and 42a ₂ of the locking member 42a (FIGS. 1 and 2).

係止体４２ａは、回転軸１４に対する径方向で被係止具４１の外周面に対向配置する。更に、この係止体４２ａは、回転軸１４の軸周りで隣り合う２つの凸部４１ａを支持するものとして形成する。また更に、この係止体４２ａは、回転軸１４に対する径方向への可撓性を持つものとして形成する。また更に、この係止体４２ａは、回転軸１４に対する径方向で被係止具４１の外周面に対向配置させ、かつ、それぞれの端部４２ａ_１，４２ａ_２の間に亘って延在させた平面部又は直線部を有する。係止体４２ａにおいては、その平面部又は直線部を、回転軸１４の軸周りで隣り合う２つの凸部４１ａを支持する係止部４２ａ_３として利用する（図１及び図２）。 The locking body 42 a is disposed to face the outer peripheral surface of the locked member 41 in the radial direction with respect to the rotation shaft 14. Further, the locking body 42a is formed to support two convex portions 41a adjacent to each other around the rotation shaft 14. Further, the locking body 42a is formed to have flexibility in the radial direction with respect to the rotating shaft 14. Furthermore, the engaging member 42a is opposed to the outer peripheral surface of the locking tool 41 in a radial direction relative to the rotation axis 14, and was extended over between the respective end portions 42a _1, 42a ₂ It has a flat part or a straight part. In engaging member 42a, utilizing the flat portion or the straight portion, as a locking portion 42a ₃ which supports the two convex portions 41a adjacent the axis around the axis of rotation 14 (FIG. 1 and FIG. 2).

この回転係止機構４０は、その係止部４２ａ_３で２つの凸部４１ａを支持することによって、被係止具４１の回転を係止するので、凹部４１ｂに従来のような突起を進入させて被係止具４１の回転を係止するものと比較して、回転を係止しているときの被係止具４１と係止具４２との間のがたつきを抑えることができる。よって、この回転係止機構４０は、回転操作子１０に対する回転操作の節度感（クリック感）を向上させることができる。 The rotation locking mechanism 40, by supporting the two protrusions 41a at the locking portion 42a _3, so to lock the rotation of Hikakaritomegu 41, is advanced a projection as in the prior art in the recess 41b As a result, it is possible to suppress rattling between the locked member 41 and the locking member 42 when the rotation is locked, as compared with a device that locks the rotation of the locked member 41. Therefore, the rotation locking mechanism 40 can improve a moderation feeling (click feeling) of the rotation operation with respect to the rotary operation element 10.

この例示の係止体４２ａにおいては、回転軸１４の径方向に対する直交方向に係止部４２ａ_３を延在させている。先のそれぞれの端部４２ａ_１，４２ａ_２とは、各々、その延在方向における一方の端部と他方の端部のことをいう。係止体４２ａは、例えば、平板状に形成し、一方の平面部を回転軸１４に対する径方向で被係止具４１の外周面に対向配置させ且つ凸部４１ａの外周面を接触させることによって、その平面部が係止部４２ａ_３となる。また、係止体４２ａは、例えば、係止部４２ａ_３の延在方向を軸線とする円柱状に形成することによって、被係止具４１の外周面に対向配置され且つ凸部４１ａの外周面が接触する直線部が係止部４２ａ_３となる。この例示では、係止体４２ａを平板状に形成し、回転軸１４の径方向と回転軸１４の軸線方向とに対する直交方向に係止部４２ａ_３を延在させている。 In this exemplary locking body 42a, and extend the locking portion 42a ₃ in the orthogonal direction to the radial direction of the rotary shaft 14. The respective ends 42a ₁ and 42a ₂ refer to one end and the other end in the extending direction, respectively. The locking body 42a is formed in, for example, a flat plate shape, and one of the flat portions is disposed so as to face the outer peripheral surface of the locked member 41 in the radial direction with respect to the rotation shaft 14 and the outer peripheral surface of the convex portion 41a is brought into contact with the locking member 42a. the planar portion serves as the engaging portion 42a _3. Further, the engaging member 42a is, for example, the outer peripheral surface of the by forming the extending direction of the engaging portion 42a ₃ in a cylindrical shape to the axis, is disposed opposite to the outer peripheral surface of Hikakaritomegu 41 and protrusion 41a There straight portion in contact becomes an engagement portion 42a _3. In this illustration, it forms a locking body 42a in a plate shape, thereby extending the engagement portion 42a ₃ in a direction perpendicular with respect to the radial direction of the rotating shaft 14 and the axial direction of the rotary shaft 14.

それぞれの被支持体４２ｂは、各々、保持具３０に対する相対変位が不能な支点４２ｂ_１を有する（図１）。 Each of the support 42b each have a fulcrum 42b ₁ of impossible relative displacement with respect to the retainer 30 (FIG. 1).

この係止具４２においては、第２基準トルク以上の回転トルクで回転操作子１０と共に被係止具４１を回転させた際に、支持している一方の凸部４１ａで係止体４２ａが押動されて撓み、他方の凸部４１ａが支持されていた位置に一方の凸部４１ａが到達したときに、係止体４２ａの撓みが解消される。この係止具４２においては、その係止体４２ａの撓みの解消と共に、回転軸１４の軸周りで隣り合う新たな一対の凸部４１ａが係止部４２ａ_３で支持されて、被係止具４１の回転が係止される。この回転係止機構４０は、第２基準トルク以上の回転トルクで回転操作子１０が続けて回転操作されている場合、同じ動作を繰り返し、第２基準トルク以上の回転トルクで回転操作子１０が続けて回転操作されなかった場合、係止具４２が被係止具４１の回転を係止したままにする。 In the locking member 42, when the locked member 41 is rotated together with the rotary operator 10 with a rotation torque equal to or greater than the second reference torque, the locking body 42a is pressed by the one of the supporting protrusions 41a. When the one protrusion 41a reaches the position where the other protrusion 41a is supported by the movement, the bending of the locking body 42a is eliminated. In this fastener 42, along with eliminating the deflection of the locking body 42a, a new pair of convex portions 41a adjacent around the axis of the rotary shaft 14 is supported by the locking portion 42a _3, Hikakaritomegu The rotation of 41 is locked. This rotation locking mechanism 40 repeats the same operation when the rotary operator 10 is continuously rotated at a rotational torque equal to or more than the second reference torque, and the rotary operator 10 is rotated at a rotational torque equal to or more than the second reference torque. If the rotation operation is not continued, the locking tool 42 keeps the rotation of the locked tool 41 locked.

この回転係止機構４０においては、隣り合う凸部４１ａの間における回転軸１４の軸周りのピッチに応じて、回転操作子１０に対する１クリック当りの回転操作量（凸部４１ａを隣の凸部４１ａの位置まで移動させる際の回転操作量）を変えることができ、かつ、回転操作子１０に対する回転操作の節度感を変えることができる。例えば、この回転係止機構４０においては、隣り合う凸部４１ａのピッチが大きいほど、凸部４１ａにより押動された係止体４２ａの撓み量が多くなるので、回転操作子１０に対する１クリックの回転操作を操作者に把握させ易く、回転操作子１０に対する回転操作の節度感を強めることができる。また、この回転係止機構４０においては、隣り合う凸部４１ａのピッチが小さいほど、凸部４１ａにより押動された係止体４２ａの撓み量が少なくなるので、回転操作子１０に対する１クリックの回転操作を操作者に把握させ難く、回転操作子１０に対する回転操作の節度感を弱めることができる。   In the rotation locking mechanism 40, the amount of rotation operation per click on the rotary operation element 10 (the projection 41a is replaced with the adjacent projection 41a) in accordance with the pitch around the rotation shaft 14 between the adjacent projections 41a. The amount of rotation operation when moving to the position 41a) can be changed, and the sense of moderation of the rotation operation on the rotation operator 10 can be changed. For example, in the rotation locking mechanism 40, the larger the pitch between the adjacent protrusions 41a, the greater the amount of bending of the locking body 42a pushed by the protrusions 41a. The rotation operation can be easily grasped by the operator, and the sense of moderation of the rotation operation with respect to the rotary operation element 10 can be enhanced. Further, in the rotation locking mechanism 40, the smaller the pitch between the adjacent protrusions 41a, the smaller the amount of bending of the locking body 42a pushed by the protrusions 41a. It is difficult for the operator to grasp the rotation operation, and the sense of moderation of the rotation operation with respect to the rotation operator 10 can be reduced.

一方、この回転係止機構４０においては、隣り合う凸部４１ａのピッチが大きいほど、凸部４１ａにより押動された係止体４２ａの撓み量が多くなり、係止部４２ａ_３から凸部４１ａへの反力が大きくなるので、回転操作子１０の回転操作に大きな力が必要になる。これに対して、この回転係止機構４０においては、隣り合う凸部４１ａのピッチが小さいほど、凸部４１ａにより押動された係止体４２ａの撓み量が少なくなり、係止部４２ａ_３から凸部４１ａへの反力が小さくなるので、回転操作子１０を小さな力で回転操作することができる。但し、この回転係止機構４０は、係止部４２ａ_３に従来のような突起を設けておらず、その突起を凸部４１ａが乗り越える必要がない。よって、この回転係止機構４０は、その突起が無い分だけ係止体４２ａの撓み量を少なくできるので、隣り合う凸部４１ａのピッチを如何様な大きさに設定しようとも、従来よりも軽い操作力で回転操作子１０を回転させることができる。従って、この回転係止機構４０は、求める節度感と回転操作力とに応じて、隣り合う凸部４１ａのピッチを設定すればよい。また、この回転係止機構４０は、係止具４２を次のような形状に形成することによって、節度感と回転操作力とを調整してもよい。 On the other hand, in the rotation locking mechanism 40, as the pitch of the adjacent convex portion 41a is large, the number of the deflection amount of the engaging body 42a which is pushed by the protrusion 41a, protrusion 41a from the engaging portion 42a ₃ Therefore, a large force is required for the rotation operation of the rotary operation member 10. In contrast, in the rotation locking mechanism 40, as the pitch of the adjacent convex portion 41a is small, the less the amount of deflection of the engaging body 42a which is pushed by the convex portion 41a, the engaging portion 42a ₃ Since the reaction force to the convex portion 41a is small, the rotary operation element 10 can be rotated with a small force. However, the rotation locking mechanism 40 is not provided as in the prior art projection the locking portion 42a _3, there is no need to get over the convex portions 41a thereof protruding. Therefore, since the rotation locking mechanism 40 can reduce the amount of bending of the locking body 42a by the amount of the projection, the pitch of the adjacent protrusions 41a can be set to any size and lighter than before. The rotary operation element 10 can be rotated by the operation force. Therefore, in the rotation locking mechanism 40, the pitch between the adjacent convex portions 41a may be set according to the sense of moderation and the rotation operation force required. Further, the rotation locking mechanism 40 may adjust the sense of moderation and the rotation operation force by forming the locking tool 42 in the following shape.

例えば、この係止具４２においては、係止体４２ａのそれぞれの端部４２ａ_１，４２ａ_２を各々被支持体４２ｂとして利用してもよい。この場合の係止具４２においては、それぞれの端部４２ａ_１，４２ａ_２が支点４２ｂ_１になる。 For example, in the locking device 42, the respective ends 42a ₁ and 42a ₂ of the locking body 42a may be used as the supported members 42b. In the locking device 42 in this case, each end 42a ₁ , 42a ₂ becomes a fulcrum 42b ₁ .

また、例えば、この係止具４２においては、係止部４２ａ_３の延在方向に対する交差方向に向けて係止体４２ａの一方の端部４２ａ_１から一方の被支持体４２ｂを延在させ、かつ、係止部４２ａ_３の延在方向に対する交差方向に向けて係止体４２ａの他方の端部４２ａ_２から他方の被支持体４２ｂを延在させてもよい。この場合、それぞれの被支持体４２ｂは、自らの延在方向における端部側に支点４２ｂ_１を有する。この係止具４２においては、一方の被支持体４２ｂの延在方向と他方の被支持体４２ｂの延在方向とが、互いに同じ向きであってもよく、互いに逆向きであってもよい。また、それぞれの被支持体４２ｂは、係止部４２ａ_３の延在方向に対して、直交させてもよく、鋭角又は鈍角で交差させてもよい。それぞれの端部４２ａ_１，４２ａ_２には、凸部４１ａにより押動された係止体４２ａの撓みに連動して、力が作用する。この場合の係止具４２は、係止体４２ａの形状が同じであるならば、それぞれの端部４２ａ_１，４２ａ_２を被支持体４２ｂの支点４２ｂ_１とする先の例示と比較して、そのそれぞれの端部４２ａ_１，４２ａ_２に作用する力をそれぞれの被支持体４２ｂに逃がすことができる。よって、この場合の回転係止機構４０は、その比較対象よりも、係止体４２ａが撓み易く、被係止具４１が回転し易いので、操作者に軽い操作力で回転操作子１０を回転操作させることができる。 Further, for example, in this fastener 42 is extended to one of the supported body 42b from one end portion 42a ₁ of the engaging body 42a toward the crossing direction with respect to the extending direction of the engaging portion 42a _3, and it may be extended to other of the support 42b from the other end 42a ₂ of the engaging body 42a toward the crossing direction with respect to the extending direction of the engaging portion 42a _3. In this case, each of the supported body 42b has a supporting point 42b ₁ on the end side in its extending direction. In the locking device 42, the extending direction of one of the supported members 42b and the extending direction of the other supported member 42b may be the same as each other, or may be opposite to each other. Further, each of the supported body 42b, to the extending direction of the engaging portion 42a _3, may also be orthogonal, may be crossed at an acute or obtuse angle. A force acts on each of the ends 42a ₁ and 42a ₂ in conjunction with the bending of the locking body 42a pushed by the projection 41a. If the shape of the locking member 42a is the same, the locking member 42 in this case is different from the above-described example in which the ends 42a ₁ and 42a ₂ are set as the fulcrum 42b ₁ of the supported member 42b. The forces acting on the respective ends 42a ₁ and 42a ₂ can be released to the respective supported members 42b. Therefore, in this case, the rotation locking mechanism 40 rotates the rotary operating element 10 with a light operating force to the operator, since the locking body 42a is more easily bent and the locked member 41 is easier to rotate than the comparison object. Can be operated.

また、例えば、この係止具４２は、係止体４２ａの一方の端部４２ａ_１と一方の被支持体４２ｂとの間を連結し、係止体４２ａの撓みに連動して当該係止体４２ａの一方の端部４２ａ_１から受けた力を吸収する第１連結体４２ｃと、係止体４２ａの他方の端部４２ａ_２と他方の被支持体４２ｂとの間を連結し、係止体４２ａの撓みに連動して当該係止体４２ａの他方の端部４２ａ_２から受けた力を吸収する第２連結体４２ｄと、を有する（図１及び図２）。この例示では、凸部４１ａにより押動された係止体４２ａの撓み方向に凸となるＵ字状に第１連結体４２ｃと第２連結体４２ｄとを形成する。この場合でも、それぞれの端部４２ａ_１，４２ａ_２には、凸部４１ａにより押動された係止体４２ａの撓みに連動して、力が作用する。この場合の係止具４２は、係止体４２ａの形状が同じであるならば、それぞれの端部４２ａ_１，４２ａ_２から被支持体４２ｂを延在させた先の例示と比較して、そのそれぞれの端部４２ａ_１，４２ａ_２に作用する力を第１連結体４２ｃと第２連結体４２ｄとに逃がした上で更にそれぞれの被支持体４２ｂに逃がすことができる。よって、この場合の回転係止機構４０は、その比較対象よりも、係止体４２ａが撓み易く、被係止具４１が回転し易いので、操作者に更に軽い操作力で回転操作子１０を回転操作させることができる。 Further, for example, the locking member 42 connects between _one end 42a1 of the locking body 42a and one supported body 42b, and interlocks with the bending of the locking body 42a. a first connecting member 42c to absorb one force received from the end 42a ₁ of the 42a, between the other end portion 42a ₂ and the other supported member 42b of the engaging body 42a connected, the engaging member in conjunction with the 42a deflection of a second connecting member 42d to absorb the force received from the other end 42a ₂ of the lock body 42a, (FIG. 1 and FIG. 2). In this example, the first connector 42c and the second connector 42d are formed in a U-shape that is convex in the bending direction of the locking member 42a pushed by the projection 41a. Even in this case, a force acts on each of the end portions 42a ₁ and 42a ₂ in conjunction with the bending of the locking body 42a pushed by the convex portion 41a. Fastener 42 in this case, if the shape of the engaging body 42a is the same, compared to the respective end portions 42a _1, illustrated from 42a ₂ ahead which extend the supported member 42b, the After the forces acting on the respective end portions 42a ₁ and 42a ₂ are released to the first connecting member 42c and the second connecting member 42d, the force can be further released to the respective supported members 42b. Therefore, in this case, the rotation locking mechanism 40 allows the locking member 42a to bend more easily and the locked member 41 to rotate more easily than the comparison object, so that the operator can rotate the rotary operator 10 with a lighter operation force. Can be rotated.

ここで、係止具４２は、それぞれの支点４２ｂ_１を介して保持具３０に一体化させることで、そのそれぞれの支点４２ｂ_１を保持具３０に対して相対変位させないようにしてもよい。保持具３０に対する相対変位が不能な部位をダイヤルスイッチ１が備えている場合、係止具４２は、その部位にそれぞれの支点４２ｂ_１を一体化させることで、そのそれぞれの支点４２ｂ_１を保持具３０に対して相対変位させないようにしてもよい。この例示では、係止具４２を合成樹脂等の絶縁性材料で成形することによって、前者を適用している。つまり、この例示の係止具４２と保持具３０は、係止具４２のそれぞれの支点４２ｂ_１が保持具３０に繋がれた絶縁性の一体成形品として形成している。よって、このダイヤルスイッチ１は、それぞれの支点４２ｂ_１を保持具３０等に固定するための取付構造を必要としないので、体格の小型化や軽量化、原価の低減を図ることができる。更に、このダイヤルスイッチ１は、被係止具４１を軸支する保持具３０と係止具４２とが一体成形されているので、これらが別体の部品である場合と比較して、被係止具４１と係止具４２との間の相対的な位置関係の精度を向上させることができるので、節度感と回転操作力の要求値に対するズレを抑えることができる。 Here, fastener 42 may be to integrate the holder 30 through the respective pivot 42b _1, may be not relative displacement respective fulcrums 42b ₁ that the holding fixture 30. In the case where the dial switch 1 is provided with a portion that cannot be displaced relative to the holder 30, the locking member 42 integrates the respective fulcrums 42 b ₁ with the corresponding part, and the respective fulcrums 42 b ₁ are held by the holder. It may not be displaced relative to 30. In this example, the former is applied by molding the locking member 42 with an insulating material such as a synthetic resin. That is, the locking part 42 and the holder 30 in this example is formed as a respective fulcrum 42b ₁ is integrally molded article of insulating tethered to the holder 30 of the fastener 42. Therefore, the dial switch 1, a respective fulcrum 42b ₁ does not require a mounting structure for securing the holder 30 or the like, it is possible to reduce the size and weight of the physique, the reduction of cost. Further, in the dial switch 1, since the holding member 30 and the locking member 42 which support the locked member 41 are integrally formed, the engagement between the holding member 30 and the locking member 42 can be reduced as compared with the case where these are separate parts. Since the accuracy of the relative positional relationship between the stopper 41 and the stopper 42 can be improved, it is possible to suppress deviation in the sense of moderation and the required value of the rotational operation force.
