(C) is an enlarged view of region B in (A).

車両用のレバースイッチ１００の操作レバー１１０は、筒状のケース１１１を有しており、このケース１１１の一端側には、当該操作レバー１１０の中心線Ｘ回りに回転する２つの回転ノブ１２０、１３０が設けられている。 The operation lever 110 of the lever switch 100 for a vehicle has a cylindrical case 111, and two rotation knobs 120 that rotate around the center line X of the operation lever 110 are provided on one end side of the case 111. 130 is provided.

これら回転ノブ１２０、１３０は、中心線Ｘ上で同軸に設けられていると共に、中心線Ｘの軸方向に間隔を空けて設けられており、回転ノブ１２０と回転ノブ１３０の間には、ケース１１１と一体に組付けられたリング状の固定ノブ１１２が位置している。 The rotary knobs 120 and 130 are provided coaxially on the center line X, and are provided with an interval in the axial direction of the center line X. Between the rotary knob 120 and the rotary knob 130, there is a case. A ring-shaped fixing knob 112 assembled integrally with 111 is located.

ケース１１１の内側には、回転ノブ１２０の回転を伝達する軸状の回転伝達部材１２１と、回転ノブ１３０の回転を伝達する筒状の回転伝達部材１３１とが、設けられており、筒状の回転伝達部材１３１は、軸状の回転伝達部材１２１に外挿された状態で、ケース１１１の内側で回転可能に支持されている。
そして、この状態において、回転伝達部材１２１と回転伝達部材１３１は、中心線Ｘ回りの周方向に相対回転可能となっている。 Inside the case 111, a shaft-shaped rotation transmission member 121 that transmits the rotation of the rotation knob 120 and a cylindrical rotation transmission member 131 that transmits the rotation of the rotation knob 130 are provided. The rotation transmission member 131 is rotatably supported inside the case 111 in a state of being extrapolated to the shaft-like rotation transmission member 121.
In this state, the rotation transmission member 121 and the rotation transmission member 131 are relatively rotatable in the circumferential direction around the center line X.

これら回転伝達部材１２１、１３１の一端１２１ａ、１３１ａは、それぞれ回転ノブ１２０、１３０に連結されており、回転伝達部材１２１と回転伝達部材１３１は、回転ノブ１２０、１３０の中心線Ｘ回りの回転に連動して、それぞれ中心線Ｘ回りに回転するようになっている。 One ends 121 a and 131 a of the rotation transmission members 121 and 131 are connected to the rotation knobs 120 and 130, respectively. The rotation transmission member 121 and the rotation transmission member 131 rotate around the center line X of the rotation knobs 120 and 130. In conjunction with each other, they rotate around the center line X.

回転伝達部材１２１、１３１の他端１２１ｂ、１３１ｂ側は、ケース１１１の他端１１１ｂから突出して、スイッチケース１４０内に位置しており、回転伝達部材１２１、１３１の他端１２１ｂ、１３１ｂには、中心線Ｘの径方向に延びる操作杆１２２、１３２が取り付けられている。
操作杆１２２、１３２の先端部１２２ａ、１３２ａは、スイッチ（図示せず）の操作子１４１ａ、１４２ａに係合しており、操作杆１２２、１３２が、回転ノブ１２０、１３０の操作に連動して中心線Ｘ回りに回転すると、操作杆１２２、１３２の先端部１２２ａ、１３２ａの位置が中心線Ｘ回りの周方向に変位する。そして、この先端部１２２ａ、１３２ａが係合する操作子１４１ａ、１４２ａが、回転ノブ１２０、１３０の回転方向に応じて決まる一方向に移動して、操作子１４１ａ、１４２ａに取り付けられた可動接点（図示せず）が、基板１４３上の固定接点（図示せず）と接離することにより、スイッチがオンまたはオフされるようになっている。 The other end 121b, 131b side of the rotation transmitting member 121, 131 protrudes from the other end 111b of the case 111 and is located in the switch case 140. The other end 121b, 131b of the rotation transmitting member 121, 131 includes Operating rods 122 and 132 extending in the radial direction of the center line X are attached.
The front end portions 122a and 132a of the operation rods 122 and 132 are engaged with operation elements 141a and 142a of a switch (not shown), and the operation rods 122 and 132 are interlocked with the operation of the rotary knobs 120 and 130. When rotating around the center line X, the positions of the tips 122a and 132a of the operation rods 122 and 132 are displaced in the circumferential direction around the center line X. Then, the operating elements 141a and 142a with which the distal end portions 122a and 132a engage are moved in one direction determined according to the rotating direction of the rotary knobs 120 and 130, and movable contacts attached to the operating elements 141a and 142a ( The switch is turned on or off by contacting and leaving a fixed contact (not shown) on the substrate 143.

ここで、操作レバー１１０の固定ノブ１１２には、回転ノブ１２０の中心線Ｘ回りの回転操作に節度感を持たせるための節度機構１２５が設けられており、この節度機構１２５は、回転ノブ１２０に設けた節度溝１２６と、固定ノブ１１２で支持されたスプリングＳｐと、スプリングＳｐの付勢力で節度溝１２６に圧接したボールＢと、を有している。 Here, the fixed knob 112 of the operation lever 110 is provided with a moderation mechanism 125 for giving a sense of moderation to the rotation operation around the center line X of the rotation knob 120, and this moderation mechanism 125 is provided with the rotation knob 120. A spring Sp supported by the fixing knob 112, and a ball B pressed against the moderation groove 126 by the urging force of the spring Sp.

そのため、回転ノブ１２０は、スプリングＳｐから作用する付勢力で、固定ノブ１１２および回転ノブ１３０から離れる方向に押されており、この回転ノブ１２０に連結された回転伝達部材１２１は、操作杆１２２との連結部である他端１２１ｂを、回転伝達部材１３１の他端１３１ｂに、中心線Ｘの軸方向から圧接させている（図４の（Ｃ）、矢印参照）。 Therefore, the rotation knob 120 is pushed in a direction away from the fixed knob 112 and the rotation knob 130 by the urging force acting from the spring Sp, and the rotation transmission member 121 connected to the rotation knob 120 is connected to the operation rod 122. Is connected to the other end 131b of the rotation transmitting member 131 in the axial direction of the center line X (see the arrow in FIG. 4C).

よって、回転伝達部材１３１は、回転伝達部材１２１から作用する押圧力で、固定ノブ１１２側に押されており、固定ノブ１１２側の一端１３１ａを、固定ノブ１１２の回転ノブ１３０側の面１１２ａに圧接させている（図３の（Ｂ）、矢印参照）。 Therefore, the rotation transmitting member 131 is pressed to the fixed knob 112 side by the pressing force acting from the rotation transmitting member 121, and one end 131 a on the fixed knob 112 side is placed on the surface 112 a on the rotating knob 130 side of the fixed knob 112. It is press-contacted (see (B) in FIG. 3, arrow).

そのため、回転ノブ１３０に連結された回転伝達部材１３１は、長手方向の一端１３１ａと他端１３１ｂが、それぞれ固定ノブ１１２と回転伝達部材１２１の他端１２１ｂに把持された状態となっており、この把持に起因する圧接力が、回転ノブ１３０を中心線Ｘ回りに回転操作する際の抵抗となってしまう。 Therefore, the rotation transmission member 131 connected to the rotation knob 130 is in a state where one end 131a and the other end 131b in the longitudinal direction are held by the fixing knob 112 and the other end 121b of the rotation transmission member 121, respectively. The pressure contact force resulting from the grip becomes a resistance when the rotary knob 130 is rotated around the center line X.

よって、回転ノブに作用する付勢力で、回転ノブの回転が阻害されないようにすることが求められている。 Therefore, it is required that the rotation of the rotary knob is not hindered by the urging force acting on the rotary knob.

本発明は、操作レバーの中心線回りに回転可能な回転ノブに、スイッチ操作部材を有する回転伝達部材が一体回転可能に連結されており、前記回転ノブの回転操作により前記回転伝達部材が回転すると、前記スイッチ操作部材によりスイッチがオン／オフされるように構成されたレバースイッチであって、
前記回転ノブは、同軸に配置された第１の回転ノブと第２の回転ノブとから構成されると共に、前記第１の回転ノブは、前記中心線方向で、前記第２の回転ノブから離れる方向に付勢されており、
前記回転伝達部材は、
前記第１の回転ノブに連結されると共に、前記第２の回転ノブの内径側を通って前記第１の回転ノブから離れる方向に延びる筒部を有する第１の回転伝達部材と、
前記第２の回転ノブに連結されると共に、前記筒部の内側で、前記第１の回転伝達部材に対して相対回転可能に設けられた第２の回転伝達部材と、から構成されており、
前記筒部には、当該筒部を前記中心線の径方向に貫通する貫通溝が、前記中心線周りの周方向に沿って形成されており、前記第２の回転伝達部材は、前記貫通溝を貫通させた連結部材を介して、前記第２の回転ノブに連結されており、
前記中心線方向の前記貫通溝の幅は、前記中心線方向の前記連結部材の幅よりも大きい幅に設定されていることを特徴とするレバースイッチとした。 In the present invention, a rotation transmission member having a switch operation member is connected to a rotation knob rotatable around the center line of the operation lever so as to be integrally rotatable, and when the rotation transmission member is rotated by a rotation operation of the rotation knob. , A lever switch configured to be turned on / off by the switch operating member,
The rotary knob includes a first rotary knob and a second rotary knob arranged coaxially, and the first rotary knob is separated from the second rotary knob in the center line direction. Biased in the direction,
The rotation transmission member is
A first rotation transmitting member coupled to the first rotation knob and having a cylindrical portion extending in a direction away from the first rotation knob through an inner diameter side of the second rotation knob;
A second rotation transmission member connected to the second rotation knob and provided inside the cylinder portion so as to be relatively rotatable with respect to the first rotation transmission member;
A through-groove that penetrates the tubular portion in the radial direction of the center line is formed in the tubular portion along a circumferential direction around the center line, and the second rotation transmission member is formed of the through-groove. Is connected to the second rotary knob via a connecting member penetrating
The width of the through groove in the center line direction is set to be larger than the width of the connecting member in the center line direction.

本発明によれば、第１の回転ノブに連結された第１の回転伝達部材の筒部の内側で、第２の回転ノブに連結された第２の回転伝達部材が、第１の回転伝達部材に対して相対回転可能に設けられているので、第１の回転ノブを第２の回転ノブから離す方向に作用する付勢力で、第１の回転伝達部材が第２の回転伝達部材から離れる方向に付勢されても、第１の回転伝達部材と第２の回転伝達部材とが直接干渉しない。これにより、第１の回転伝達部材が連結された第１の回転ノブと、第２の回転伝達部材が連結された第２の回転ノブの回転が阻害されない。
特に、第１の回転伝達部材の筒部に設けた貫通溝の中心線方向の幅が、第２の回転伝達部材と第２のノブとを連結する連結部材の幅よりも大きいので、第２の回転ノブから離れる方向に付勢されている第１の回転ノブの位置の中心線Ｘの軸方向の変位により、第１の回転ノブに連結されている第１の回転伝達部材が変位しても、第１の回転伝達部材の筒部と、第２の回転伝達部材と第２のノブとを連結する連結部材とが干渉しないようにできる。
これにより、第２の回転伝達部材と第２の回転伝達部材を他の部材と干渉させることなく、第１の回転伝達部材と第２の回転伝達部材とを相対回転させることができるので、第１の回転伝達部材と第２の回転伝達部材の回転が阻害されて、第１の回転ノブや第２の回転ノブの回転が阻害されることがない。
よって、第１の回転ノブを第２のノブから離す方向に作用する付勢力で、第１の回転ノブや第２の回転ノブ回転が阻害されることがない。 According to the present invention, the second rotation transmission member connected to the second rotation knob on the inside of the cylindrical portion of the first rotation transmission member connected to the first rotation knob is configured to transmit the first rotation transmission. Since the first rotation knob is provided so as to be rotatable relative to the member, the first rotation transmission member is separated from the second rotation transmission member by an urging force acting in a direction in which the first rotation knob is separated from the second rotation knob. Even if biased in the direction, the first rotation transmission member and the second rotation transmission member do not directly interfere with each other. Thereby, rotation of the 1st rotation knob to which the 1st rotation transmission member was connected, and the 2nd rotation knob to which the 2nd rotation transmission member was connected is not inhibited.
In particular, the width in the center line direction of the through groove provided in the cylindrical portion of the first rotation transmission member is larger than the width of the connecting member that connects the second rotation transmission member and the second knob. The first rotation transmission member connected to the first rotation knob is displaced by the axial displacement of the center line X of the position of the first rotation knob biased away from the first rotation knob. In addition, the cylindrical portion of the first rotation transmission member and the connecting member that connects the second rotation transmission member and the second knob can be prevented from interfering with each other.
Thus, the first rotation transmission member and the second rotation transmission member can be relatively rotated without causing the second rotation transmission member and the second rotation transmission member to interfere with other members. The rotation of the first rotation transmission member and the second rotation transmission member is not inhibited, and the rotation of the first rotation knob and the second rotation knob is not inhibited.
Therefore, rotation of the first rotary knob or the second rotary knob is not hindered by the urging force acting in the direction in which the first rotary knob is separated from the second knob.

When the rotary knob 3 is operated and rotated around the center line X, the rotation transmitting member 6 connected to the rotary knob 3 also rotates around the center line X.

回転伝達部材６は、前記した連結部６１ａを先端に有する軸部６１と、この軸部６１よりも大径の円筒状の筒部６２と、から一体に形成されており、ケース２内において回転伝達部材６は、中心線Ｘに沿って設けられている。 The rotation transmitting member 6 is integrally formed from a shaft portion 61 having the connecting portion 61a at the tip and a cylindrical tube portion 62 having a diameter larger than that of the shaft portion 61, and rotates in the case 2.

When the operating lever 1 is assembled to a switch case (not shown), the engaging portion at the tip of the leg portion 82 is provided. As in the case of FIG. 4, the switch 82a is engaged with the switch operator.

図１に示すように、筒部６２の内部には、連結ピンＰを介して回転ノブ４に連結された回転伝達部材７が収容されており、筒部６２（回転伝達部材６）と回転伝達部材７とは、中心線Ｘ回りの相対回転が許容された状態で、互いに組み付けられている。 As shown in FIG. 1, a rotation transmission member 7 connected to the rotary knob 4 via a connecting pin P is accommodated in the cylinder portion 62, and the cylinder portion 62 (the rotation transmission member 6) and the rotation transmission. The member 7 is assembled with each other in a state in which relative rotation around the center line X is allowed.

図３の（Ｃ）に示すように、回転伝達部材７は、筒部６２に挿入される円柱状の基部７１を有している。この基部７１の中心線Ｘ方向の長さＬ１は、筒部６２の中心線Ｘ方向の長さＬ２よりも長くなっており、回転伝達部材６と回転伝達部材７とを組み付けた際に、基部７１の一端に設けた係合部７１ａが、筒部６２の外部に位置するようになっている（図３の（Ａ）参照）。 As shown in FIG. 3C, the rotation transmission member 7 has a columnar base 71 that is inserted into the cylindrical portion 62. The length L1 of the base portion 71 in the center line X direction is longer than the length L2 of the cylindrical portion 62 in the center line X direction, and when the rotation transmission member 6 and the rotation transmission member 7 are assembled, the base portion An engaging portion 71a provided at one end of 71 is positioned outside the cylindrical portion 62 (see FIG. 3A).

図２の（Ｂ）に示すように、係合部７１ａは、筒部６２とほぼ同じ外径Ｄ１で形成されており、この係合部７１ａには、操作杆９の環状の取付部９１が外嵌して取り付けられている。
操作杆９は、取付部９１から中心線Ｘの径方向に延びる脚部９２を有しており、操作レバー１が図示しないスイッチケースに組み付けられた際に、脚部９２の先端の係合部９２ａが、図４の場合と同様にスイッチの操作子に係合するようになっている。 As shown in FIG. 2B, the engaging portion 71a is formed with an outer diameter D1 substantially the same as the cylindrical portion 62, and an annular mounting portion 91 of the operating rod 9 is formed on the engaging portion 71a. It is attached by external fitting.
The operating rod 9 has a leg portion 92 extending from the mounting portion 91 in the radial direction of the center line X. When the operating lever 1 is assembled to a switch case (not shown), the engaging portion at the tip of the leg portion 92 is provided. Similarly to the case of FIG. 4, 92a is engaged with the switch operator.

図２の（Ａ）に示すように、基部７１の回転ノブ４側の端部７１ｂには、柱状の連結ピンＰが嵌入される貫通孔７２が形成されており、この貫通孔７２は、図３の（Ｂ）に示すように、基部７１の直径線Ｌｎに沿って基部７１を貫通している。
貫通孔７２は、連結ピンＰの外径と整合する内径の大径部７２ａと、この大径部７２ａよりも小径の小径部７２ｂと、から構成されており、この貫通孔７２に連結ピンＰを嵌入すると、連結ピンＰが常に大径部７２ａの部分にのみ嵌入されて、連結ピンＰの基部７１からの突出高さｈが、常に同じになるようになっている。 As shown in FIG. 2A, a through hole 72 into which a columnar connecting pin P is inserted is formed in the end 71b of the base 71 on the rotary knob 4 side. 3 (B), the base 71 is penetrated along the diameter line Ln of the base 71.

連結部４２は、固定ノブ５の基部５２と、ケース２との間のスリット２３を通って、ケース２の内部に延びており、この連結部４２の内径側の先端に、連結ピンＰの一端が係合する係合部４２ａが設けられている。 As shown in FIG. 2A, the rotary knob 4 connected to the rotation transmitting member 7 via the connecting pin P includes a cylindrical operation part 41 and a connection part 42 extending from the operation part 41 to the inner diameter side. ,have.
The width W of the operation portion 41 in the direction of the center line X is set to a width that covers the outer periphery of the recess 22 provided in the case 2 and the outer periphery of the base portion 52 of the adjacent fixed knob 5. The connecting portion 42 extends into the inside of the case 2 from the approximate center of the.
The connecting portion 42 passes through the slit 52 between the base 52 of the fixed knob 5 and the case 2 and extends into the case 2. One end of the connecting pin P is connected to the inner diameter end of the connecting portion 42. The engaging part 42a which engages is provided.

回転ノブ４に隣接する固定ノブ５では、環状の外周部５１１の内側が基部５２となっており、この基部５２の中央部に、前記した回転伝達部材６の軸部６１を挿通させる挿通孔５２１が形成されている。
この挿通孔５２１の径方向外側には、スプリングＳｐの支持孔５２２が、中心線Ｘに沿って形成されており、この支持孔５２２は、回転ノブ３側に開口している。
支持孔５２２は、中心線Ｘ回りの周方向に複数設けられており、支持孔５２２の各々では、スプリングＳｐで支持されたボールＢが、中心線Ｘの軸方向に進退移動可能に設けられている。 In the fixed knob 5 adjacent to the rotation knob 4, the inner side of the annular outer peripheral portion 511 is a base portion 52, and an insertion hole 521 through which the shaft portion 61 of the rotation transmission member 6 is inserted in the center portion of the base portion 52. Is formed.
A support hole 522 of the spring Sp is formed along the center line X on the outer side in the radial direction of the insertion hole 521, and the support hole 522 opens to the rotary knob 3 side.
A plurality of support holes 522 are provided in the circumferential direction around the center line X, and in each of the support holes 522, the balls B supported by the springs Sp are provided so as to be movable back and forth in the axial direction of the center line X. Yes.

支持孔５２２の各々は、回転ノブ３側に開口するリング状の凹溝５２２ａで接続されており、スプリングＳｐで支持されたボールＢは、回転ノブ３側の一部を凹溝５２２ａ内に位置させている。
回転ノブ３の基部３２では、凹溝５２２ａに対向する位置に、環状壁３３が形成されている。この環状壁３３は、固定ノブ５側に突出しており、凹溝５２２ａ内に位置させた先端に、スプリングＳｐで付勢されたボールＢが、中心線Ｘの軸方向から圧接している。 Each of the support holes 522 is connected by a ring-shaped concave groove 522a that opens to the rotary knob 3 side, and the ball B supported by the spring Sp is located at a part of the rotary knob 3 side in the concave groove 522a. I am letting.
In the base 32 of the rotary knob 3, an annular wall 33 is formed at a position facing the concave groove 522a. The annular wall 33 protrudes toward the fixed knob 5, and the ball B urged by the spring Sp is in pressure contact with the tip located in the concave groove 522 a from the axial direction of the center line X.

実施の形態では、スプリングＳｐと、ボールＢと、環状壁３３とから、節度機構４０を構成しており、回転ノブ３を中心線Ｘ回りに回転させる際に、環状壁３３に圧接させたボールＢが環状壁３３を摺動することで、回転ノブ３の回転操作に節度感が発揮されるようになっている。 In the embodiment, the moderation mechanism 40 is constituted by the spring Sp, the ball B, and the annular wall 33, and the ball pressed against the annular wall 33 when the rotary knob 3 is rotated around the center line X. B slides on the annular wall 33 so that a sense of moderation is exhibited in the rotation operation of the rotary knob 3.

ここで、スプリングＳｐの付勢力は、環状壁３３に圧接させたボールＢを介して、回転ノブ３に作用しており、中心線Ｘの軸方向において回転ノブ３は、固定ノブ５および回転ノブ４から離れる方向に付勢されている。
そのため、この回転ノブ３に連結された回転伝達部材６もまた、回転ノブ３と同方向に付勢されており、回転伝達部材６は、軸部６１と筒部６２との境界に位置する段部６３を、固定ノブ５の基部５２に設けた突起５２ａに圧接させている（図２の（Ａ）参照）。
この突起５２ａは、基部５２の回転ノブ４側の面５２３から、回転ノブ４側に突出して設けられており、中心線Ｘ回りの周方向に間隔を空けて複数設けられている。 Here, the urging force of the spring Sp acts on the rotary knob 3 via the ball B pressed against the annular wall 33. In the axial direction of the center line X, the rotary knob 3 includes the fixed knob 5 and the rotary knob. It is energized in a direction away from 4.
Therefore, the rotation transmission member 6 connected to the rotation knob 3 is also urged in the same direction as the rotation knob 3, and the rotation transmission member 6 is a step located at the boundary between the shaft portion 61 and the cylindrical portion 62. The part 63 is brought into pressure contact with a protrusion 52a provided on the base 52 of the fixing knob 5 (see FIG. 2A).
The protrusions 52 a are provided so as to protrude from the surface 523 of the base 52 on the rotary knob 4 side toward the rotary knob 4, and a plurality of the protrusions 52 a are provided at intervals in the circumferential direction around the center line X.

実施の形態では、段部６３を全面に亘って基部５１２に接触させるのではなく、基部５１２に設けた突起５１２ａに接触させて、段部６３と回転伝達部材６との接触面積を抑えることで、回転伝達部材６が回転するときの摺動抵抗が低減されるようにしている。
さらに、中心線Ｘ方向での回転伝達部材６の位置決めが、基部５１２に設けた突起５１２ａにより行われるようになっている。この際に、回転伝達部材６の筒部６２の一端６２ａと、回転伝達部材７の一端に設けた係合部７１ａとの間に隙間Ｓ（図２の（Ｂ）参照）が形成されて、回転伝達部材６と回転伝達部材７とが中心線Ｘ回りに相対回転しても、筒部６２の一端６２ａと係合部７１ａとが摺動しないようになっている。 In the embodiment, the step portion 63 is not brought into contact with the base portion 512 over the entire surface, but is brought into contact with the protrusion 512a provided on the base portion 512, thereby suppressing the contact area between the step portion 63 and the rotation transmitting member 6. The sliding resistance when the rotation transmitting member 6 rotates is reduced.
Further, the rotation transmission member 6 is positioned in the direction of the center line X by a projection 512 a provided on the base 512. At this time, a gap S (see FIG. 2B) is formed between one end 62a of the cylindrical portion 62 of the rotation transmitting member 6 and an engaging portion 71a provided at one end of the rotation transmitting member 7. Even if the rotation transmitting member 6 and the rotation transmitting member 7 are relatively rotated around the center line X, the one end 62a of the cylindrical portion 62 and the engaging portion 71a do not slide.

さらに、実施の形態では、回転伝達部材６の筒部６２に設けた貫通溝６４の中心線Ｘの軸方向の幅Ｗ１は、連結ピンＰの幅Ｗ２よりも大きい幅に設定されており、回転伝達部材６の段部６３が基部５１に設けた突起５１ａに接触する位置で位置決めされる際に、回転伝達部材６が中心線Ｘの軸方向に変位しても、筒部６２の貫通溝６４と、回転伝達部材７と回転ノブ４とを連結する連結ピンＰとが接触しないようになっている。
そのため、回転伝達部材６と回転伝達部材７とが中心線Ｘ回りに相対回転する際に、貫通溝６４と連結ピンＰとが摺動しないようになっている。 Furthermore, in the embodiment, the axial width W1 of the center line X of the through groove 64 provided in the cylindrical portion 62 of the rotation transmitting member 6 is set to be larger than the width W2 of the connecting pin P, and the rotation Even when the rotation transmitting member 6 is displaced in the axial direction of the center line X when the stepped portion 63 of the transmitting member 6 is positioned at a position in contact with the protrusion 51 a provided on the base portion 51, the through groove 64 of the cylindrical portion 62. And the connection pin P which connects the rotation transmission member 7 and the rotation knob 4 does not contact.
Therefore, when the rotation transmission member 6 and the rotation transmission member 7 are relatively rotated around the center line X, the through groove 64 and the connecting pin P are prevented from sliding.

なお、実施の形態にかかる操作レバー１もまた、図４に示した操作レバー１１０の場合と同様に、回転ノブ３、４を回転操作すると、回転伝達部材６、７に取り付けられた操作杆９、８が、回転ノブ３、４の回転方向に応じて決まる一方向に回転するようになっている。これにより、操作杆９、８の脚部９２、８２の係合部９２ａ、８２ａの位置が、中心線Ｘ周りの周方向に変位して、スイッチの操作子（図示せず）を変位させるので、操作子に設けられた可動接点（図示せず）が、基板上の可動接点（図示せず）に対して接離して、スイッチがオンまたはオフされるようになっている。 Note that the operating lever 1 according to the embodiment also operates the operating lever 9 attached to the rotation transmitting members 6 and 7 when the rotating knobs 3 and 4 are rotated as in the case of the operating lever 110 shown in FIG. , 8 rotate in one direction determined according to the rotation direction of the rotary knobs 3, 4. As a result, the positions of the engaging portions 92a and 82a of the leg portions 92 and 82 of the operating rods 9 and 8 are displaced in the circumferential direction around the center line X, thereby displacing a switch operator (not shown). A movable contact (not shown) provided on the operation element is brought into contact with and separated from a movable contact (not shown) on the substrate, so that the switch is turned on or off.

以上の通り、実施の形態では、
（１）操作レバー１の中心線Ｘ回りに回転可能な回転ノブ３、４に、操作杆８、９を有する回転伝達部材６、７が一体回転可能に連結されており、回転ノブ３、４の回転操作により回転伝達部材６、７が回転すると、操作杆８、９が有するスイッチとの係合部８２ａ、９２ａの位置が中心線Ｘ回りの周方向に変位して、スイッチがオン／オフされるように構成されたレバースイッチであって、

(1) The rotation transmission members 6 and 7 having the operation rods 8 and 9 are connected to the rotary knobs 3 and 4 that can rotate about the center line X of the operation lever 1 so as to be integrally rotatable. When the rotation transmitting members 6 and 7 are rotated by the rotation operation, the positions of the engaging portions 82a and 92a with the switch of the operation rods 8 and 9 are displaced in the circumferential direction around the center line X, and the switch is turned on / off. A lever switch configured to be
The rotary knob 3 is biased in a direction away from the rotary knob 4,
The rotation transmission member 6 has a cylindrical portion 62 that is connected to the rotation knob 3 and extends in a direction away from the rotation knob 3 through the inner diameter side of the rotation knob 4.
The rotation transmission member 7 is connected to the rotation knob 4 and is provided inside the cylindrical portion 62 so as to be relatively rotatable with respect to the rotation transmission member 6.
A through groove 64 that penetrates the cylindrical portion 62 in the radial direction of the center line X is formed in the cylindrical portion 62 over a predetermined angular range around the central line X, and the rotation transmitting member 7 is , Connected to the rotary knob 4 via a connecting pin P that penetrates the through groove 64.
The width W1 of the through groove 64 in the center line X direction is a lever switch configured to be larger than the width W2 of the connecting pin P in the center line X direction.

このように構成すると、回転ノブ３に連結された回転伝達部材６の筒部６２の内側で、回転ノブ４に連結された回転伝達部材７が、回転伝達部材６に対して相対回転可能に設けられているので、回転ノブ３を回転ノブ４から離す方向に作用する付勢力で、回転伝達部材６が回転伝達部材７から離れる方向に付勢されても、回転伝達部材７と回転伝達部材６とが直接干渉しない。これにより、回転ノブ３に作用する付勢力で回転伝達部材７と回転伝達部材６とが干渉する場合のように、回転伝達部材７と回転伝達部材６との相対回転が阻害されることがないので、回転ノブ３と回転ノブ４の回転が阻害されない。
さらに、回転伝達部材６の筒部６２に設けた貫通溝６４の中心線方向の幅Ｗ１が、回転伝達部材７と回転ノブ４とを連結する連結ピンＰの中心線Ｘ方向の幅Ｗ２よりも大きいので、回転ノブ４から離れる方向に付勢されている回転ノブ３の中心線Ｘ方向の位置の変位により、回転ノブ３に連結された回転伝達部材６の位置が変位しても、回転伝達部材６の筒部６２と、回転伝達部材７と回転ノブ４とを連結する連結ピンＰとが干渉しないようにできる。
これにより、回転伝達部材６と回転伝達部材７を他の部材と干渉させることなく、回転伝達部材６と回転伝達部材７とを中心線Ｘの軸方向で相対的に移動させることができるので、回転伝達部材６と回転伝達部材７の回転が阻害されて、回転ノブ３や回転ノブ４の回転が阻害されることがない。
よって、回転ノブ３を回転ノブ４から離す方向に作用する付勢力で、回転ノブ３や回転ノブ４の回転が阻害されることがない。 If comprised in this way, the rotation transmission member 7 connected with the rotation knob 4 is provided inside the cylinder part 62 of the rotation transmission member 6 connected with the rotation knob 3 so that relative rotation with respect to the rotation transmission member 6 is possible. Therefore, even if the rotation transmitting member 6 is urged in the direction away from the rotation transmitting member 7 by the urging force acting in the direction away from the rotating knob 4, the rotation transmitting member 7 and the rotation transmitting member 6. And do not interfere directly. Accordingly, the relative rotation between the rotation transmission member 7 and the rotation transmission member 6 is not hindered as in the case where the rotation transmission member 7 and the rotation transmission member 6 interfere with each other with the urging force acting on the rotation knob 3. Therefore, the rotation of the rotary knob 3 and the rotary knob 4 is not hindered.
Further, the width W1 of the through groove 64 provided in the cylindrical portion 62 of the rotation transmitting member 6 in the center line direction is larger than the width W2 of the connecting pin P connecting the rotation transmitting member 7 and the rotation knob 4 in the center line X direction. Even if the position of the rotation transmission member 6 connected to the rotation knob 3 is displaced due to the displacement of the position in the direction of the center line X of the rotation knob 3 biased away from the rotation knob 4, the rotation transmission is performed. The cylindrical portion 62 of the member 6 and the connecting pin P that connects the rotation transmitting member 7 and the rotating knob 4 can be prevented from interfering with each other.
Thereby, the rotation transmission member 6 and the rotation transmission member 7 can be relatively moved in the axial direction of the center line X without causing the rotation transmission member 6 and the rotation transmission member 7 to interfere with other members. The rotation of the rotation transmitting member 6 and the rotation transmitting member 7 is not inhibited, and the rotation of the rotation knob 3 and the rotation knob 4 is not inhibited.
Therefore, the urging force acting in the direction separating the rotary knob 3 from the rotary knob 4 does not hinder the rotation of the rotary knob 3 or the rotary knob 4.

（２）回転伝達部材７の中心線Ｘ方向の長さＬ１は、筒部６２の中心線Ｘ方向の長さＬ２よりも長くなっており、回転伝達部材７では、筒部６０の回転ノブ３とは反対側の一端６２ａから突出させた係合部７１ａに、操作杆８が設けられている構成とした。 (2) The length L1 of the rotation transmission member 7 in the center line X direction is longer than the length L2 of the cylinder portion 62 in the center line X direction. The operating rod 8 is provided on the engaging portion 71a protruding from the one end 62a on the opposite side.

このように構成すると、回転ノブ３を回転ノブ４から離れる方向に付勢する付勢力で、回転伝達部材６は、回転伝達部材７の操作杆８から離れる方向に付勢されているので、回転伝達部材６と、回転伝達部材７の操作杆８との接触を好適に防止できる。
これにより、回転伝達部材７と、回転伝達部材７の操作杆８との接触に起因して、回転伝達部材６と回転伝達部材７の回転が阻害されて、回転ノブ３や回転ノブ４の回転が阻害されることがない。 If comprised in this way, since the rotation transmission member 6 is urged | biased in the direction away from the operating rod 8 of the rotation transmission member 7 with the urging | biasing force which urges | biases the rotation knob 3 in the direction away from the rotation knob 4, rotation Contact between the transmission member 6 and the operating rod 8 of the rotation transmission member 7 can be suitably prevented.
Thereby, due to the contact between the rotation transmission member 7 and the operating rod 8 of the rotation transmission member 7, the rotation of the rotation transmission member 6 and the rotation transmission member 7 is obstructed, and the rotation knob 3 and the rotation knob 4 rotate. Is not inhibited.

（３）回転伝達部材６では、回転ノブ３の内径側で、当該回転ノブ３に連結される円柱形状の軸部６１の回転ノブ４側の一端から、筒部６２が、回転ノブ３から離れる方向に延びている構成とした。 (3) In the rotation transmission member 6, the cylindrical portion 62 is separated from the rotation knob 3 from one end on the rotation knob 4 side of the cylindrical shaft portion 61 connected to the rotation knob 3 on the inner diameter side of the rotation knob 3. It was set as the structure extended in the direction.

このように構成すると、回転伝達部材６は、筒部６２よりも剛性の高い軸部６１の部分で回転ノブ３に連結されるので、回転ノブ３と回転伝達部材６とをより高い剛性強度で連結できる。
回転ノブ３との剛性強度が低いと、回転伝達部材６が中心線Ｘに対して傾いて配置されて、この回転伝達部材６と一体に回転する回転ノブ３の中心線Ｘ回りの回転が阻害される虞があるが、回転ノブ３と回転伝達部材６とをより高い剛性強度で連結すると、回転伝達部材６が中心線Ｘに対する傾きをより確実に防止できるので、回転ノブ３の中心線Ｘ回りの回転が阻害されることがない。 If comprised in this way, since the rotation transmission member 6 is connected with the rotation knob 3 in the part of the axial part 61 whose rigidity is higher than the cylinder part 62, the rotation knob 3 and the rotation transmission member 6 are provided with higher rigidity and strength. Can be linked.
If the rigidity with the rotary knob 3 is low, the rotation transmission member 6 is inclined with respect to the center line X, and the rotation around the center line X of the rotation knob 3 rotating integrally with the rotation transmission member 6 is obstructed. However, if the rotation knob 3 and the rotation transmission member 6 are connected with higher rigidity and strength, the rotation transmission member 6 can be more reliably prevented from tilting with respect to the center line X. Rotation around is not hindered.

（４）筒部６２の外径は、軸部６１よりも大きい外径で形成されて、軸部６１と筒部６２の境界に段部６３が形成されており、

A protrusion 52 a protruding from the base 52 of the fixed knob 5 disposed between the rotary knob 3 and the rotary knob 4 is in contact with the step 63 from the axial direction of the center line X,
A plurality of protrusions 52a are provided at equal intervals in the circumferential direction around the center line X.

このように構成すると、回転ノブ３を回転ノブ４から離れる方向に付勢する付勢力で、回転伝達部材６は、段部６３が、固定側部材である基部５２の突起５２ａに当接する位置で位置決めされるので、回転伝達部材６の筒部６２と、回転伝達部材７と回転ノブ４とを連結する連結ピンＰとの干渉をより確実に防止できる。
また、段部６３が全面に亘って固定側部材である基部５２に接触するのではなく、基部５２に設けた突起５２ａに接触しているので、段部６３と固定側部材との接触面積を少なくできる。よって、回転伝達部材６が回転するときの摺動抵抗を低減できるので、回転ノブ３の回転操作が摺動抵抗により大きく阻害されることがない。 If comprised in this way, the rotation transmission member 6 is the position which the step part 63 contact | abuts to the processus | protrusion 52a of the base 52 which is a fixed side member by the urging | biasing force which urges | biases the rotation knob 3 in the direction away from the rotation knob 4. Since the positioning is performed, interference between the cylindrical portion 62 of the rotation transmitting member 6 and the connecting pin P that connects the rotation transmitting member 7 and the rotating knob 4 can be prevented more reliably.
Further, since the step portion 63 is not in contact with the base portion 52 that is the fixed side member over the entire surface, but is in contact with the protrusion 52a provided on the base portion 52, the contact area between the step portion 63 and the fixed side member is reduced. Less. Therefore, since the sliding resistance when the rotation transmitting member 6 rotates can be reduced, the rotation operation of the rotary knob 3 is not greatly hindered by the sliding resistance.

（５）固定側部材である基部５２と回転ノブ３との間には、回転ノブ３の中心線Ｘ回りの回転操作に節度感を与える節度機構４０が設けられており、
節度機構４０は、基部５２で支持されたスプリングＳｐにより、中心線Ｘ方向に進退移動可能とされたボールＢと、回転ノブ３に設けられて、球体が圧接する環状壁３３と、から構成されており、
回転ノブ３を回転ノブ４から離す方向に作用する付勢力は、スプリングＳＰの付勢力である構成とした。 (5) A moderation mechanism 40 is provided between the base 52, which is a fixed side member, and the rotary knob 3 to give a moderation feeling to the rotation operation around the center line X of the rotary knob 3.
The moderation mechanism 40 includes a ball B that can be moved forward and backward in the direction of the center line X by a spring Sp supported by the base 52, and an annular wall 33 that is provided on the rotary knob 3 and press-contacts the sphere. And
The biasing force acting in the direction of separating the rotary knob 3 from the rotary knob 4 is configured to be the biasing force of the spring SP.
