The X direction corresponds to the vertical direction in FIG. 1, and the Y direction corresponds to the horizontal direction in FIG. Moreover, the front-back direction of FIG. 1 is called a Z direction. Further, when the operation lever 1 is viewed from the housing 2, the right side in the Y direction is referred to as right and the left side in the Y direction is referred to as left.
　筐体２は、操作レバー１を保持する保持機構を収納する収納部であり、略直方体形状を有し、下面２ａ、側面２ｂ、及び上面２ｃにより構成される。下面２ａは、筐体２に収納された制御回路３と、ＣＡＮ（Controller Area Network）などにより構成された車載システムと、を接続するためのポート２１を備える。 The housing 2 is a storage portion that stores a holding mechanism that holds the operation lever 1, has a substantially rectangular parallelepiped shape, and includes a lower surface 2a, a side surface 2b, and an upper surface 2c.

In the example of FIG. 2, the side surface 2b and the upper surface 2c are omitted. As shown in FIG. 2, the housing 2 accommodates therein a control circuit 3, a shaft 4, a connection portion 5, a first holding unit 6, and a second holding unit 7. The holding mechanism of the operation lever 1 includes a first holding unit 6 and a second holding unit 7.
　制御回路３は、操作レバー１及び操作スイッチ１１の操作に応じた信号を、ポート２１を介して車載システムに出力する回路であり、下面２ａ上に設けられる。制御回路３は、レバースイッチ装置１００の伝達線をそれぞれ接続するための複数の端子３１を備える。また、制御回路３は、レバースイッチ装置１００からの信号に基づいて、操作レバー１の位置を検出する検出回路を備える。 The control circuit 3 is a circuit that outputs a signal corresponding to the operation of the operation lever 1 and the operation switch 11 to the in-vehicle system via the port 21, and is provided on the lower surface 2a. The control circuit 3 includes a plurality of terminals 31 for connecting the transmission lines of the lever switch device 100, respectively. The control circuit 3 includes a detection circuit that detects the position of the operation lever 1 based on a signal from the lever switch device 100.

To be arranged. The portion of the shaft 4 disposed inside the operation lever 1 is fixed to the operation lever 1 by a method such as fitting or bonding so that the shaft 4 is interlocked with the operation lever 1.
　操作スイッチ１１に接続された伝達線１２ａ，１２ｂは、シャフト４の内側を通って、筐体２の内側に導入される。すなわち、シャフト４は、操作レバー１から筐体２への、伝達線１２ａ，１２ｂの配線経路を構成する。シャフト４を通って筐体２の内側に導入された伝達線１２ａ，１２ｂは、それぞれ端子３１を介して制御回路３に接続される。これにより、操作スイッチ１１の機械的変移が端子３１に伝達されて、制御回路３に入力される。 The transmission lines 12a and 12b connected to the operation switch 11 are introduced into the housing 2 through the inside of the shaft 4. That is, the shaft 4 constitutes a wiring path of the transmission lines 12 a and 12 b from the operation lever 1 to the housing 2. The transmission lines 12 a and 12 b introduced into the inside of the housing 2 through the shaft 4 are connected to the control circuit 3 via terminals 31, respectively. As a result, the mechanical change of the operation switch 11 is transmitted to the terminal 31 and input to the control circuit 3.
　接続部５は、シャフト４における、操作レバー１の基端部（操作レバー１と筐体２との間）に、シャフト４と同軸に設けられる。接続部５は、シャフト４と連動するように、シャフト４に固定される。操作レバー１と筐体２（保持機構）とは、接続部５を介して接続される。接続部５は、操作レバー１と一体的に回動可能となっており、操作レバー１の２方向の回動の支点の役割を果たす。接続部５は、Ｘ方向に配置された一対の凸部５１ａ，５１ｂと、Ｙ方向に配置された一対の凸部５２ａ，５２ｂと、を備える。凸部５１ａ，５１ｂ及び凸部５２ａ，５２ｂについては後述する。図３の例では、接続部５は、シャフト４に固定された球状のボールジョイントであるが、これに限られない。接続部５は、操作レバー１と一体的に回動可能な任意の構成とすることができる。例えば、接続部５は、操作レバー１の基端部やその周辺部に、操作レバー１と一体に成形され、操作レバー１と一体的に回動可能となっていてもよい。 The connecting portion 5 is provided coaxially with the shaft 4 at the base end portion (between the operating lever 1 and the housing 2) of the operating lever 1 in the shaft 4. The connecting portion 5 is fixed to the shaft 4 so as to be interlocked with the shaft 4. The operation lever 1 and the housing 2 (holding mechanism) are connected via a connection portion 5. The connecting portion 5 can be rotated integrally with the operation lever 1 and serves as a fulcrum for turning the operation lever 1 in two directions. The connecting portion 5 includes a pair of convex portions 51a and 51b arranged in the X direction and a pair of convex portions 52a and 52b arranged in the Y direction. The convex portions 51a and 51b and the convex portions 52a and 52b will be described later. In the example of FIG. 3, the connecting portion 5 is a spherical ball joint fixed to the shaft 4, but is not limited thereto. The connecting portion 5 can have an arbitrary configuration that can rotate integrally with the operation lever 1. For example, the connection portion 5 may be formed integrally with the operation lever 1 at the base end portion or the peripheral portion of the operation lever 1, and may be rotatable integrally with the operation lever 1.
　図４～図９は、第１保持ユニット６を説明するための分解図である。図４～図９の例では、説明に利用しない構成が適宜省略されている。 4 to 9 are exploded views for explaining the first holding unit 6. In the examples of FIGS. 4 to 9, configurations that are not used in the description are omitted as appropriate.
　図４に示すように、第１保持ユニット６は、第１軸受部６１ａ，６１ｂと、第１挟持部６２ａ，６２ｂと、第１トーションバネ６３ａ，６３ｂと、駆動部６４と、伝達線６５と、を備える。 As shown in FIG. 4, the first holding unit 6 includes first bearing portions 61 a and 61 b, first holding portions 62 a and 62 b, first torsion springs 63 a and 63 b, a drive portion 64, and a transmission line 65. .
　第１軸受部６１ａ，６１ｂは、操作レバー１がＸ方向に回動可能なように、接続部５をＸ方向から挟持する一対の軸受部である。本明細書において、挟持するとは、挟んだ状態で支持することをいう。第１軸受部６１ａ，６１ｂは、シャフト４の中心を通る直線上に、対向するように配置される。第１軸受部６１ａ，６１ｂは、第１軸受部６１ａが接続部５を上方から支持し、第１軸受部６１ｂが接続部５を下方から支持することにより、接続部５をＸ方向から挟持する。 The first bearing portions 61a and 61b are a pair of bearing portions that sandwich the connection portion 5 from the X direction so that the operation lever 1 can rotate in the X direction. In this specification, “to pinch” means to support in a pinched state. The first bearing portions 61 a and 61 b are arranged to face each other on a straight line passing through the center of the shaft 4. The first bearing portions 61a and 61b sandwich the connection portion 5 from the X direction by the first bearing portion 61a supporting the connection portion 5 from above and the first bearing portion 61b supporting the connection portion 5 from below. .
　第１軸受部６１ａには、上方に突出した軸部６１１ａが設けられる。第１軸受部６１ｂには、下方に突出した軸部６１１ｂが設けられる。図５に示すように、軸部６１１ａは、上面２ｃに設けられた軸受部２２ａに嵌合し、Ｙ方向に回動可能に支持される。また、軸部６１１ｂは、下面２ａに設けられた軸受部２２ｂに嵌合し、Ｙ方向に回動可能に支持される。このような構成により、第１軸受部６１ａ，６１ｂは、筐体２に、軸部６１１ａ，６１１ｂを軸としてＹ方向に回動可能に取り付けられる。 The shaft portion 611a protruding upward is provided on the first bearing portion 61a. The first bearing portion 61b is provided with a shaft portion 611b protruding downward. As shown in FIG. 5, the shaft portion 611a is fitted to a bearing portion 22a provided on the upper surface 2c, and is supported so as to be rotatable in the Y direction. The shaft portion 611b is fitted into a bearing portion 22b provided on the lower surface 2a, and is supported so as to be rotatable in the Y direction. With such a configuration, the first bearing portions 61a and 61b are attached to the housing 2 so as to be rotatable in the Y direction about the shaft portions 611a and 611b.
　また、図６に示すように、第１軸受部６１ａの下面（接続部５との接触面）は球面状であり、接続部５の凸部５１ａと嵌合する凹部６１２ａを形成される。凹部６１２ａは、Ｙ方向の幅が凸部５１ａのＹ方向の幅と略同一となり、Ｚ方向の幅が凸部５１ａのＺ方向の移動量より長くなるように形成される。凹部６１２ａにより、操作レバー１のねじり動作、すなわちＺ方向の回動軸周りの回動動作が規制される。 As shown in FIG. 6, the lower surface of the first bearing portion 61 a (the contact surface with the connection portion 5) has a spherical shape, and a recess 612 a that fits with the protrusion 51 a of the connection portion 5 is formed. The recess 612a is formed such that the width in the Y direction is substantially the same as the width in the Y direction of the protrusion 51a, and the width in the Z direction is longer than the amount of movement of the protrusion 51a in the Z direction. The recess 612a restricts the torsional operation of the operation lever 1, that is, the rotational operation around the rotational axis in the Z direction.
　同様に、図７に示すように、第１軸受部６１ｂの上面（接続部５との接触面）は球面状であり、接続部５の凸部５１ｂと嵌合する凹部６１２ｂを形成される。凹部６１２ｂは、Ｙ方向の幅が凸部５１ｂのＹ方向の幅と略同一となり、Ｚ方向の幅が凸部５１ｂのＺ方向の移動量より長くなるように形成される。凹部６１２ｂにより、操作レバー１のねじり動作、すなわちＺ方向の回動軸周りの回動動作が規制される。 Similarly, as shown in FIG. 7, the upper surface of the first bearing portion 61 b (the contact surface with the connection portion 5) has a spherical shape, and a concave portion 612 b that fits with the convex portion 51 b of the connection portion 5 is formed. The recess 612b is formed such that the width in the Y direction is substantially the same as the width in the Y direction of the protrusion 51b, and the width in the Z direction is longer than the amount of movement of the protrusion 51b in the Z direction. The recess 612b restricts the torsional operation of the operation lever 1, that is, the rotational operation around the rotational axis in the Z direction.
　このような構成により、接続部５は、操作レバー１がＸ方向に回動可能なように、第１軸受部６１ａ，６１ｂにより挟持される。 With such a configuration, the connection portion 5 is sandwiched between the first bearing portions 61a and 61b so that the operation lever 1 can rotate in the X direction.
　第１挟持部６２ａ，６２ｂは、シャフト４がＸ方向に回動可能なように、Ｙ方向からシャフト４を挟持して保持（固定）する一対の挟持部である。第１挟持部６２ａ，６２ｂがシャフト４を挟持することにより、操作レバー１が所定の保持位置で保持される。図４に示すように、第１挟持部６２ａ，６２ｂは、対向する位置に配置され、第１挟持部６２ａがシャフト４を左方から支持し、第１挟持部６２ｂがシャフト４を右方から支持することにより、シャフト４をＹ方向から挟持する。 The first sandwiching portions 62a and 62b are a pair of sandwiching portions that sandwich and hold (fix) the shaft 4 from the Y direction so that the shaft 4 can rotate in the X direction. When the first clamping portions 62a and 62b clamp the shaft 4, the operation lever 1 is held at a predetermined holding position. As shown in FIG. 4, the first clamping parts 62a and 62b are arranged at opposing positions, the first clamping part 62a supports the shaft 4 from the left side, and the first clamping part 62b supports the shaft 4 from the right side. By supporting, the shaft 4 is clamped from the Y direction.

Hereinafter, when the first holding portions 66a, 66b, and 66c are not distinguished, they are referred to as first holding portions 66. The first holding portion 66 is a portion into which the shaft 4 is fitted, and corresponds to a portion in which the shaft 4 side is recessed as compared with other portions.
　シャフト４は、第１保持部６６に嵌合した状態で、第１挟持部６２ａ，６２ｂにより保持される。操作レバー１の保持位置は、シャフト４が第１挟持部６２ａ，６２ｂにより保持された際の操作レバー１の位置に相当する。したがって、第１保持部６６の位置は、操作レバー１の保持位置に対応する。具体的には、操作レバー１の下端の保持位置は、第１保持部６６ａの位置に対応し、操作レバー１の中央の保持位置は、第１保持部６６ｂの位置に対応し、操作レバー１の上端の保持位置は、第１保持部６６ｃの位置に対応する。これは、操作レバー１とシャフト４とが逆向きに移動するためである。 The shaft 4 is held by the first holding portions 62a and 62b in a state of being fitted to the first holding portion 66. The holding position of the operation lever 1 corresponds to the position of the operation lever 1 when the shaft 4 is held by the first clamping portions 62a and 62b. Therefore, the position of the first holding portion 66 corresponds to the holding position of the operation lever 1. Specifically, the holding position of the lower end of the operating lever 1 corresponds to the position of the first holding portion 66a, the holding position in the center of the operating lever 1 corresponds to the position of the first holding portion 66b, and the operating lever 1 The upper end holding position corresponds to the position of the first holding portion 66c. This is because the operation lever 1 and the shaft 4 move in opposite directions.
　図９の例のように、第１保持部６６の周囲が、第１保持部６６に向かって傾斜している場合、第１保持部６６の周囲に位置するシャフト４は、第１保持部６６の周囲の傾斜や操作レバー１の重さにより、第１保持部６６に向かって自動的に移動し、第１保持部６６で保持される。 As shown in the example of FIG. 9, when the periphery of the first holding part 66 is inclined toward the first holding part 66, the shaft 4 positioned around the first holding part 66 has the first holding part 66. Is automatically moved toward the first holding portion 66 by the inclination of the surroundings and the weight of the operation lever 1 and is held by the first holding portion 66.

Hereinafter, when the second holding portions 76a, 76b, and 76c are not distinguished, they are referred to as second holding portions 76. The second holding portion 76 is a portion into which the shaft 4 is fitted, and corresponds to a portion in which the shaft 4 side is recessed as compared with other portions.
　シャフト４は、第２保持部７６に嵌合した状態で、第２挟持部７２ａ，７２ｂにより保持される。操作レバー１の保持位置は、シャフト４が第２挟持部７２ａ，７２ｂにより保持された際の操作レバー１の位置に相当する。したがって、第２保持部７６の位置は、操作レバー１の保持位置に対応する。具体的には、操作レバー１の右端の保持位置は、第２保持部７６ａの位置に対応し、操作レバー１の中央の保持位置は、第２保持部７６ｂの位置に対応し、操作レバー１の左端の保持位置は、第２保持部７６ｃの位置に対応する。これは、操作レバー１とシャフト４とが逆向きに移動するためである。 The shaft 4 is held by the second holding portions 72a and 72b in a state of being fitted to the second holding portion 76. The holding position of the operation lever 1 corresponds to the position of the operation lever 1 when the shaft 4 is held by the second clamping portions 72a and 72b. Therefore, the position of the second holding portion 76 corresponds to the holding position of the operation lever 1. Specifically, the holding position at the right end of the operating lever 1 corresponds to the position of the second holding portion 76a, the holding position at the center of the operating lever 1 corresponds to the position of the second holding portion 76b, and the operating lever 1 The leftmost holding position corresponds to the position of the second holding portion 76c. This is because the operation lever 1 and the shaft 4 move in opposite directions.
　図１５の例のように、第２保持部７６の周囲が、第２保持部７６に向かって傾斜している場合、第２保持部７６の周囲に位置するシャフト４は、第２保持部７６の周囲の傾斜や操作レバー１の重さにより、第２保持部７６に向かって自動的に移動し、第２保持部７６で保持される。 As shown in the example of FIG. 15, when the periphery of the second holding portion 76 is inclined toward the second holding portion 76, the shaft 4 positioned around the second holding portion 76 has the second holding portion 76. Is automatically moved toward the second holding portion 76 and held by the second holding portion 76 due to the inclination of the surroundings and the weight of the operation lever 1.
　なお、第２挟持部７２ｂの第３部分７２３ｂの代わりに、第２挟持部７２ａの第３部分７２３ａに第２保持部が設けられてもよい。また、第３部分７２３ａ，７２３ｂの対向する位置に、第２保持部がそれぞれ設けられてもよい。また、第２挟持部７２ａ，７２ｂに設けられる第２保持部の数は任意である。また、図１５の例では、シャフト４の断面形状は、円形であるが、八角形であってもよいし、任意の多角形であってもよい。また、第２保持部の周囲は、平坦であってもよい。 In addition, the 2nd holding part may be provided in the 3rd part 723a of the 2nd clamping part 72a instead of the 3rd part 723b of the 2nd clamping part 72b. In addition, second holding portions may be provided at positions where the third portions 723a and 723b face each other. Moreover, the number of the 2nd holding | maintenance parts provided in the 2nd clamping parts 72a and 72b is arbitrary. In the example of FIG. 15, the cross-sectional shape of the shaft 4 is a circle, but may be an octagon or an arbitrary polygon. The periphery of the second holding unit may be flat.
　また、第２挟持部７２ａ，７２ｂは、第１挟持部６２ａ，６２ｂとぶつからないように形成される。具体的には、第１部分７２１ａ，７２１ｂ及び第２部分７２２ａ，７２２ｂの外縁が、第１部分６２１ａ，６２１ｂ及び第２部分６２２ａ，６２２ｂの内縁より短く形成される。第１部分７２１ａ，７２１ｂ及び第２部分７２２ａ，７２２ｂの内縁が、第１部分６２１ａ，６２１ｂ及び第２部分６２２ａ，６２２ｂの外縁より長く形成されてもよい。 Further, the second holding parts 72a and 72b are formed so as not to collide with the first holding parts 62a and 62b. Specifically, the outer edges of the first parts 721a and 721b and the second parts 722a and 722b are formed shorter than the inner edges of the first parts 621a and 621b and the second parts 622a and 622b. The inner edges of the first parts 721a and 721b and the second parts 722a and 722b may be formed longer than the outer edges of the first parts 621a and 621b and the second parts 622a and 622b.
　第２トーションバネ７３ａ，７３ｂは、第２挟持部７２ａ，７２ｂを接続し、第２挟持部７２ａ，７２ｂを、互いに近づく方向に付勢するトーションバネである。第２トーションバネ７３ａ，７３ｂのアーム角は、例えば、０度以下である。 The second torsion springs 73a and 73b are torsion springs that connect the second clamping parts 72a and 72b and urge the second clamping parts 72a and 72b in a direction approaching each other. The arm angles of the second torsion springs 73a and 73b are, for example, 0 degrees or less.
　図１４に示すように、第２トーションバネ７３ａは、巻線部に軸部７２６ｂが挿通され、一方のアームが係止部７２４ａに係止され、他方のアームが係止部７２４ｂに係止される。また、図１０に示すように、第２トーションバネ７３ｂは、巻線部に軸部７２７ｂが挿通され、一方のアームが係止部７２４ａに係止され、他方のアームが係止部７２４ｂに係止される。 As shown in FIG. 14, in the second torsion spring 73a, the shaft portion 726b is inserted into the winding portion, one arm is locked to the locking portion 724a, and the other arm is locked to the locking portion 724b. The Further, as shown in FIG. 10, the second torsion spring 73b has a shaft portion 727b inserted through the winding portion, one arm locked to the locking portion 724a, and the other arm engaged to the locking portion 724b. Stopped.
　このような構成により、第２挟持部７２ａが第２挟持部７２ｂの方向に付勢され、第２挟持部７２ｂが第２挟持部７２ａの方向に付勢される。結果として、第２挟持部７２ａ，７２ｂにより、シャフト４が挟持される。 With such a configuration, the second clamping part 72a is urged in the direction of the second clamping part 72b, and the second clamping part 72b is urged in the direction of the second clamping part 72a. As a result, the shaft 4 is clamped by the second clamping parts 72a and 72b.
　なお、第２保持ユニット７は、図１０の例のように、２つの第２トーションバネ７３ａ，７３ｂを備えてもよいし、第２トーションバネ７３ａ，７３ｂのいずれか一方だけを備えてもよい。 The second holding unit 7 may include two second torsion springs 73a and 73b as in the example of FIG. 10, or may include only one of the second torsion springs 73a and 73b. .
　駆動部７４は、操作レバー１のＸ方向の変位を、伝達線７５を介して端子３１に伝達して、制御回路３に入力するための部分である。図１０に示すように、駆動部７４は、軸部７１１ｂに設けられる。操作レバー１がＸ方向に移動すると、当該移動に伴って、軸部７１１ｂが回動し、当該回動に伴って、駆動部７４が回動する。制御回路３には、操作レバー１のＸ方向の変位に応じて、駆動部７４の変位が端子３１に伝達されて入力される。 The drive unit 74 is a part for transmitting the displacement of the operation lever 1 in the X direction to the terminal 31 via the transmission line 75 and inputting it to the control circuit 3. As shown in FIG. 10, the drive part 74 is provided in the axial part 711b. When the operation lever 1 moves in the X direction, the shaft portion 711b rotates with the movement, and the driving unit 74 rotates with the rotation. According to the displacement of the operation lever 1 in the X direction, the displacement of the drive unit 74 is transmitted to the terminal 31 and input to the control circuit 3.
　なお、駆動部７４が、その位置を検出するセンサを備え、当該センサからの信号を、信号線を介して制御回路３に入力してもよい。また、別の場所に操作レバー１のＸ方向の変位を検出するセンサを備え、当該センサからの信号を直接制御回路３に入力してもよい。 The driving unit 74 may include a sensor that detects the position, and a signal from the sensor may be input to the control circuit 3 via a signal line. Further, a sensor that detects the displacement of the operation lever 1 in the X direction may be provided at another location, and a signal from the sensor may be directly input to the control circuit 3.
　次に、本実施形態に係るレバースイッチ装置１００の動作について、図１６を参照して説明する。以下では、中央の保持位置に位置する操作レバー１（図２参照）を、運転者が左方の保持位置に移動させる場合を例に説明する。図１６は、操作レバー１の移動後のレバースイッチ装置１００の状態を示す分解図である。 Next, the operation of the lever switch device 100 according to the present embodiment will be described with reference to FIG. Below, the case where the driver | operator moves the control lever 1 (refer FIG. 2) located in the center holding position to the left holding position is demonstrated to an example. FIG. 16 is an exploded view showing a state of the lever switch device 100 after the operation lever 1 is moved.
　運転者が操作レバー１を左方へ移動させると、操作レバー１と連動して、シャフト４が右方へ移動する。第１保持ユニット６は、シャフト４の右方への移動に伴って、第１挟持部６２ａ，６２ｂがシャフト４を挟持した状態（シャフト４が第１保持部６６ｂに嵌合した状態）で、軸部６１１ａ，６１１ｂを軸として右方に回動する。また、軸部６１１ｂの回動と連動して、駆動部６４も変位する。 When the driver moves the control lever 1 to the left, the shaft 4 moves to the right in conjunction with the control lever 1. The first holding unit 6 is in a state where the first holding portions 62a and 62b hold the shaft 4 as the shaft 4 moves to the right (the state where the shaft 4 is fitted to the first holding portion 66b). It rotates rightward with the shaft portions 611a and 611b as axes. Further, the drive unit 64 is also displaced in conjunction with the rotation of the shaft unit 611b.
　一方、第２保持ユニット７は、Ｙ方向に延びた軸部７１１ａ，７１１ｂにより筐体２に固定されているため、シャフト４の右方へ移動しても回動しない。このため、操作レバー１が運転者により左方へ移動されると、シャフト４は、第２挟持部７２ａ，７２ｂを押し広げながら右方へ移動する。軸部７１１ｂは回動しないため、駆動部７４は変異しない。 On the other hand, since the second holding unit 7 is fixed to the housing 2 by the shaft portions 711a and 711b extending in the Y direction, it does not rotate even if it moves to the right of the shaft 4. For this reason, when the operating lever 1 is moved leftward by the driver, the shaft 4 moves rightward while expanding the second holding portions 72a and 72b. Since the shaft portion 711b does not rotate, the drive portion 74 is not mutated.
　図１６に示すように、シャフト４は、第２保持部７６ｃの位置まで移動すると、第２保持部７６ｃと嵌合し、第２挟持部７２ａ，７２ｂにより、その場で保持される。これにより、操作レバー１が、左端の保持位置で保持される。この際、制御回路３には、伝達線６５を介して、駆動部６４の変位が入力される。制御回路３は、入力された当該変移により、操作レバー１が左端の保持位置に位置していることを検出する。 As shown in FIG. 16, when the shaft 4 moves to the position of the second holding portion 76c, the shaft 4 is fitted to the second holding portion 76c and is held on the spot by the second holding portions 72a and 72b. As a result, the operation lever 1 is held at the holding position at the left end. At this time, the displacement of the drive unit 64 is input to the control circuit 3 via the transmission line 65. The control circuit 3 detects that the operation lever 1 is located at the leftmost holding position by the input transition.
　なお、運転者は、上記同様の方法により、操作レバー１を右方、上方、及び下方へと移動させることができる。操作レバー１が右方、上方、又は下方へ移動された場合、シャフト４は、左方、下方、又は上方にそれぞれ移動し、第２保持部７６ａ、第１保持部６６ｃ、又は第１保持部６６ａにそれぞれ嵌合した状態で、第１保持ユニット６及び第２保持ユニット７に保持される。 The driver can move the operation lever 1 rightward, upward, and downward by the same method as described above. When the operation lever 1 is moved rightward, upward, or downward, the shaft 4 moves leftward, downward, or upward, respectively, and the second holding part 76a, the first holding part 66c, or the first holding part. It is held by the first holding unit 6 and the second holding unit 7 in a state of being fitted to 66a.
　以上説明した通り、本実施形態によれば、操作レバー１を保持する第１保持ユニット６及び第２保持ユニット７が、筐体２を介さずに、操作レバー１と一体化されたシャフト４及び接続部５に対して取り付けられる。このような構成により、シャフト４と、シャフト４を保持する第１保持部６６及び第２保持部７６と、の間の累積公差が小さくなるため、操作レバー１の保持位置のずれを抑制できる。 As described above, according to the present embodiment, the first holding unit 6 and the second holding unit 7 that hold the operation lever 1 are integrated with the operation lever 1 without using the housing 2. It is attached to the connecting portion 5. With such a configuration, since the accumulated tolerance between the shaft 4 and the first holding unit 66 and the second holding unit 76 that hold the shaft 4 is reduced, the shift of the holding position of the operation lever 1 can be suppressed.
　また、本実施形態によれば、第１保持ユニット６にＸ方向の第１保持部６６が設けられ、第２保持ユニット７にＹ方向の第２保持部７６が設けられる。このような構成により、各保持ユニットの形状（第１挟持部６２ａ，６２ｂ及び第２挟持部７２ａ，７２ｂの形状）を単純化できる。この結果、操作レバー１の操作時に、第１保持ユニット６及び第２保持ユニット７により加える操作荷重（クリック感）を容易に設定できる。 Further, according to the present embodiment, the first holding unit 6 is provided with the first holding part 66 in the X direction, and the second holding unit 7 is provided with the second holding part 76 in the Y direction. With such a configuration, the shape of each holding unit (the shape of the first holding parts 62a and 62b and the second holding parts 72a and 72b) can be simplified. As a result, the operation load (click feeling) applied by the first holding unit 6 and the second holding unit 7 when the operation lever 1 is operated can be easily set.
　なお、上記実施形態に挙げた構成等に、その他の要素との組み合わせなど、ここで示した構成に本発明が限定されるものではない。これらの点に関しては、本発明の趣旨を逸脱しない範囲で変更可能であり、その応用形態に応じて適切に定めることができる。 It should be noted that the present invention is not limited to the configuration shown here, such as a combination with other elements in the configuration described in the above embodiment. These points can be changed without departing from the spirit of the present invention, and can be appropriately determined according to the application form.
　また、本国際出願は、２０１７年５月２３日に出願した日本国特許出願第２０１７－１０２１０５号に基づく優先権を主張するものであり、当該出願の全内容を本国際出願に援用する。 This international application claims priority based on Japanese Patent Application No. 2017-102105 filed on May 23, 2017, and the entire contents of the application are incorporated herein by reference.
