Thus, it is preferable that the second shaft portion 132a be formed such that the height from the second side surface 132 is higher from the upper side to the lower side. Thereby, the pressing force required to attach the operation knob 14 to the mounting portion 13 can be reduced.

　開口部１４１ａ，１４１ｂは、それぞれ外装部１４１の右側面及び左側面に形成された円形の開口部である。開口部１４１ａ，１４１ｂは、操作つまみ１４を射出成型により一体形成する際に、後述する第１軸受部１４２ａ及び第２軸受部１４３ａを形成するために付随的に形成される開口部である。したがって、外装部１４１は、開口部１４１ａ，１４１ｂを備えなくてもよい。 The openings 141a and 141b are circular openings formed on the right side and the left side of the exterior portion 141, respectively. The openings 141a and 141b are openings that are additionally formed to form a first bearing 142a and a second bearing 143a, which will be described later, when the operation knob 14 is integrally formed by injection molding. Therefore, the exterior portion 141 may not include the openings 141a and 141b.
　絵文字１４１ｃは、図１に示すように、外装部１４１の上面に形成された、絵文字形状の部分であり、光を透過可能なように形成される。絵文字１４１ｃは、外装部１４１の他の部分と異なる透明な材料により形成されてもよいし、外装部１４１の肉薄部分として形成されてもよい。ＬＥＤ９が発光すると、ＬＥＤ９からの光が、光透過部２６を介して、絵文字１４１ｃを透過する。これにより、ユーザは、暗い場所であっても絵文字１４１ｃを容易に視認できる。結果として、スイッチ装置１００の利便性を向上できる。 The pictogram 141 c is a pictogram shaped portion formed on the top surface of the exterior portion 141 as shown in FIG. 1, and is formed so as to be able to transmit light. The pictogram 141 c may be formed of a transparent material different from the other portions of the exterior portion 141, or may be formed as a thin portion of the exterior portion 141. When the LED 9 emits light, the light from the LED 9 transmits the pictogram 141 c through the light transmitting portion 26. Thereby, the user can easily visually recognize the pictogram 141 c even in a dark place. As a result, the convenience of the switch device 100 can be improved.
　図５に示すように、押圧部１４１ｄは、カム１１を押圧する部分であり、スイッチ装置１００を組み立て際に、カム１１と対応する部分（カム１１の上方）に設けられる。図５の例では、押圧部１４１ｄは、外装部１４１の前端部から下方に突出するように設けられている。押圧部１４１ｄは、操作つまみ１４における、左右方向の中央から所定距離だけ離間して配置される。また、押圧部１４１ｄは、後述する第１軸受部１４２ａ及び第２軸受部１４３ａより前方に設けられる。操作つまみ１４が、その前端部が下降するように操作されると、押圧部１４１ｄが下降してカム１１を押圧する。これにより、カム１１が下降し、スイッチ装置１００から、操作つまみ１４の操作に応じた信号が出力される。 As shown in FIG. 5, the pressing portion 141 d is a portion that presses the cam 11, and is provided at a portion (above the cam 11) corresponding to the cam 11 when the switch device 100 is assembled. In the example of FIG. 5, the pressing portion 141 d is provided so as to project downward from the front end portion of the exterior portion 141. The pressing portion 141 d is disposed at a predetermined distance from the center in the left-right direction of the operation knob 14. Further, the pressing portion 141 d is provided in front of the first bearing portion 142 a and the second bearing portion 143 a described later. When the operation knob 14 is operated to lower its front end, the pressing portion 141 d is lowered to press the cam 11. Thus, the cam 11 is lowered, and a signal corresponding to the operation of the operation knob 14 is output from the switch device 100.
　押圧部１４１ｅは、カム１２を押圧する部分であり、スイッチ装置１００を組み立て際に、カム１２と対応する位置（カム１２の上方）に設けられる。図５の例では、押圧部１４１ｅは、外装部１４１の後部から下方に突出するように設けられている。押圧部１４１ｅは、操作つまみ１４における、左右方向の中央から所定距離だけ離間して配置される。また、押圧部１４１ｅは、後述する第１軸受部１４２ａ及び第２軸受部１４３ａより後方に設けられる。操作つまみ１４が、その後端部が下降するように操作されると、押圧部１４１ｅが下降してカム１２を押圧する。これにより、カム１２が下降し、スイッチ装置１００から、操作つまみ１４の操作に応じた信号が出力される。 The pressing portion 141 e is a portion that presses the cam 12, and is provided at a position corresponding to the cam 12 (above the cam 12) when the switch device 100 is assembled. In the example of FIG. 5, the pressing portion 141 e is provided so as to protrude downward from the rear of the exterior portion 141. The pressing portion 141 e is disposed apart from the center in the left-right direction of the operation knob 14 by a predetermined distance. In addition, the pressing portion 141e is provided rearward of a first bearing portion 142a and a second bearing portion 143a described later. When the operation knob 14 is operated to lower its rear end, the pressing portion 141 e is lowered to press the cam 12. As a result, the cam 12 is lowered, and a signal corresponding to the operation of the operation knob 14 is output from the switch device 100.
　第１取付面１４２及び第２取付面１４３は、外装部１４１の側面に平行な板状部材であり、外装部１４１の内側に、対向して配置される。第１取付面１４２及び第２取付面１４３は、操作つまみ１４を取付部１３に取り付けるための、後述する取付構造を有する。外装部１４１の内側に、取付構造を有する第１取付面１４２及び第２取付面１４３を設けることにより、取付構造が外部から見えなくなり、操作つまみ１４の美観が向上する。なお、操作つまみ１４は、第１取付面１４２及び第２取付面１４３を備えず、外装部１４１の側面に取付構造を設けられてもよい。 The first mounting surface 142 and the second mounting surface 143 are plate-like members parallel to the side surface of the exterior portion 141, and are disposed to face each other on the inside of the exterior portion 141. The first attachment surface 142 and the second attachment surface 143 have an attachment structure, which will be described later, for attaching the operation knob 14 to the attachment portion 13. By providing the first attachment surface 142 and the second attachment surface 143 having the attachment structure inside the exterior part 141, the attachment structure can not be seen from the outside, and the appearance of the operation knob 14 is improved. The operation knob 14 may not be provided with the first attachment surface 142 and the second attachment surface 143, and the attachment structure may be provided on the side surface of the exterior part 141.
　図６は、左方からみた図５のＡ－Ａ線断面図である。図６に示すように、第１取付面１４２は、外装部１４１の内側に、外装部１４１の内面から下方に延びるように形成されており、その下端が前後方向に水平な直線状である。第１取付面１４２は、第１軸受部１４２ａと、第１嵌合部１４２ｂと、を備える。 6 is a cross-sectional view taken along the line AA of FIG. 5 as viewed from the left. As shown in FIG. 6, the first attachment surface 142 is formed inside the exterior portion 141 so as to extend downward from the inner surface of the exterior portion 141, and the lower end thereof is straight in the horizontal direction in the front-rear direction. The first mounting surface 142 includes a first bearing portion 142 a and a first fitting portion 142 b.
　第１軸受部１４２ａは、第１側面１３１に設けられた第１軸部１３１ａが嵌合する部分である。図６の例では、第１軸受部１４２ａは、円形の貫通孔であるが、円形の凹部として形成されてもよい。第１軸受部１４２ａに第１軸部１３１ａが嵌合すると、第１軸部１３１ａを軸として操作つまみ１４は揺動可能となる。 The first bearing portion 142 a is a portion with which the first shaft portion 131 a provided on the first side surface 131 is fitted. In the example of FIG. 6, the first bearing portion 142 a is a circular through hole, but may be formed as a circular recess. When the first shaft portion 131a is fitted to the first bearing portion 142a, the operation knob 14 can swing around the first shaft portion 131a.
　第１嵌合部１４２ｂは、第１側面１３１に設けられた第１抜け止め部１３１ｂが嵌合する部分であり、第１軸受部１４２ａに第１軸部１３１ａを嵌合した際に第１抜け止め部１３１ｂと対応する位置（第１抜け止め部１３１ｂの左側）に設けられる。本実施形態では、第１抜け止め部１３１ｂが第１軸部１３１ａより後方に配置されるため、第１嵌合部１４２ｂは第１軸受部１４２ａより後方に配置されるが、第１抜け止め部１３１ｂが第１軸部１３１ａより前方に配置される場合には、第１嵌合部１４２ｂは第１軸受部１４２ａより前方に配置される。なお、図６の例では、第１嵌合部１４２ｂは、貫通孔であるが、凹部として形成されてもよい。 The first fitting portion 142b is a portion to which the first retaining portion 131b provided on the first side surface 131 is fitted, and when the first shaft portion 131a is fitted to the first bearing portion 142a, the first fitting portion 142b is removed.

In the present embodiment, the first fitting portion 142b is disposed rearward of the first bearing portion 142a because the first retaining portion 131b is disposed rearward of the first shaft portion 131a. When 131b is disposed in front of the first shaft portion 131a, the first fitting portion 142b is disposed in front of the first bearing portion 142a. In addition, in the example of FIG. 6, although the 1st fitting part 142b is a through-hole, you may be formed as a recessed part.
　第１嵌合部１４２ｂは、第１軸受部１４２ａの中心を中心とした円弧状に、第１抜け止め部１３１ｂより広く形成される。第１軸受部１４２ａに第１軸部１３１ａが嵌合し、第１嵌合部１４２ｂに第１抜け止め部１３１ｂが嵌合すると、操作つまみ１４は、第１軸部１３１ａを中心として、所定の角度範囲内で回転可能、すなわち、揺動可能となる。所定の角度範囲は、第１抜け止め部１３１ｂの上端が第１嵌合部１４２ｂの上端に接触する際の角度から、第１抜け止め部１３１ｂの下端が第１嵌合部１４２ｂの下端に接触する際の角度まで、の範囲である。すなわち、第１嵌合部１４２ｂは、その下端及び上端が第１抜け止め部１３１ｂと接触することにより、操作つまみ１４が揺動可能な範囲を規制する。 The first fitting portion 142b is formed wider than the first retaining portion 131b in an arc shape centering on the center of the first bearing portion 142a. When the first shaft portion 131a is fitted to the first bearing portion 142a and the first retaining portion 131b is fitted to the first fitting portion 142b, the operation knob 14 has a predetermined centering on the first shaft portion 131a. It is rotatable, i.e. swingable, within an angular range. The predetermined angle range is the angle at which the upper end of the first retaining portion 131b contacts the upper end of the first fitting portion 142b, and the lower end of the first retaining portion 131b contacts the lower end of the first fitting portion 142b. The range is up to the angle at which That is, when the lower end and the upper end of the first fitting portion 142b contact the first retaining portion 131b, the range in which the operation knob 14 can swing is restricted.
　図７は、右方からみた図５のＡ－Ａ線断面図である。図７に示すように、第２取付面１４３は、外装部１４１の内側に、外装部１４１の内面から下方に延びるように形成されており、下端が前後方向に水平な直線状である。第２取付面１４３の下端の上下方向の高さは、第１取付面１４２の下端の上下方向の高さと一致する。第２取付面１４３は、第２軸受部１４３ａと、第２嵌合部１４３ｂと、を備える。 7 is a cross-sectional view taken along the line AA of FIG. 5 as viewed from the right side. As shown in FIG. 7, the second attachment surface 143 is formed on the inside of the exterior portion 141 so as to extend downward from the inner surface of the exterior portion 141, and the lower end thereof is straight in the horizontal direction in the front-rear direction. The vertical height of the lower end of the second mounting surface 143 coincides with the vertical height of the lower end of the first mounting surface 142. The second attachment surface 143 includes a second bearing portion 143a and a second fitting portion 143b.
　第２軸受部１４３ａは、第２側面１３２に設けられた第２軸部１３２ａが嵌合する部分である。図７の例では、第２軸受部１４３ａは、円形の貫通孔であるが、円形の凹部として形成されてもよい。第２軸受部１４３ａに第２軸部１３２ａが嵌合すると、第２軸部１３２ａを軸として操作つまみ１４は揺動可能となる。 The second bearing portion 143 a is a portion with which the second shaft portion 132 a provided on the second side surface 132 is fitted. In the example of FIG. 7, the second bearing portion 143a is a circular through hole, but may be formed as a circular recess. When the second shaft portion 132a is fitted to the second bearing portion 143a, the operation knob 14 can swing around the second shaft portion 132a.
　第２嵌合部１４３ｂは、第２側面１３２に設けられた第２抜け止め部１３２ｂが嵌合する部分であり、第２軸受部１４３ａに第２軸部１３２ａを嵌合した際に第２抜け止め部１３２ｂと対応する位置（第２抜け止め部１３２ｂの右側）に設けられる。本実施形態では、第２抜け止め部１３２ｂが第２軸部１３２ａより後方に配置されるため、第２嵌合部１４３ｂは第２軸受部１４３ａより後方に配置されるが、第２抜け止め部１３２ｂが第２軸部１３２ａより前方に配置される場合には、第２嵌合部１４３ｂは第２軸受部１４３ａより前方に配置される。なお、図７の例では、第２嵌合部１４３ｂは、貫通孔であるが、凹部として形成されてもよい。 The second fitting portion 143b is a portion to which the second retaining portion 132b provided on the second side surface 132 is fitted, and when the second shaft portion 132a is fitted to the second bearing portion 143a, the second fitting portion 143b is removed. It is provided in the position (right side of the 2nd securing part 132b) corresponding to stop part 132b. In the present embodiment, since the second retaining portion 132b is disposed rearward of the second shaft portion 132a, the second fitting portion 143b is disposed rearward of the second bearing portion 143a. When 132b is disposed in front of the second shaft portion 132a, the second fitting portion 143b is disposed in front of the second bearing portion 143a. In the example of FIG. 7, the second fitting portion 143b is a through hole, but may be formed as a recess.
　第２嵌合部１４３ｂは、第２軸受部１４３ａの中心を中心とした円弧状に、第２抜け止め部１３２ｂより広く形成される。第２軸受部１４３ａに第２軸部１３２ａが嵌合し、第２嵌合部１４３ｂに第２抜け止め部１３２ｂが嵌合すると、操作つまみ１４は、第２軸部１３２ａを中心として、所定の角度範囲内で回転可能、すなわち、揺動可能となる。所定の角度範囲は、第２抜け止め部１３２ｂの上端が第２嵌合部１４３ｂの上端に接触する際の角度から、第２抜け止め部１３２ｂの下端が第２嵌合部１４３ｂの下端に接触する際の角度まで、の範囲である。すなわち、第２嵌合部１４３ｂは、その下端及び上端が第２抜け止め部１３２ｂと接触することにより、操作つまみ１４が揺動可能な範囲を規制する。 The second fitting portion 143b is formed wider than the second retaining portion 132b in an arc shape centering on the center of the second bearing portion 143a. When the second shaft portion 132a is fitted to the second bearing portion 143a and the second retaining portion 132b is fitted to the second fitting portion 143b, the operation knob 14 has a predetermined centering on the second shaft portion 132a. It is rotatable, i.e. swingable, within an angular range. The predetermined angle range is the angle at which the upper end of the second retaining portion 132b contacts the upper end of the second fitting portion 143b, and the lower end of the second retaining portion 132b contacts the lower end of the second fitting portion 143b. The range is up to the angle at which That is, when the lower end and the upper end of the second fitting portion 143b contact the second retaining portion 132b, the range in which the operation knob 14 can swing is restricted.
　次に、本実施形態に係るスイッチ装置１００の組み立て方法について説明する。以下、スイッチ装置１００を作業者が組み立てる場合を例に説明する。 Next, a method of assembling the switch device 100 according to the present embodiment will be described. Hereinafter, a case where a worker assembles the switch device 100 will be described as an example.
　まず、作業者は、カバー１の内側に外部接続端子３及び回路基板８を収納し、外部接続端子３及び回路基板８を、はんだ付けなどにより電気的に接続する。次に、作業者は、回路基板８に形成された固定接点４～７と、クリックゴム１０に形成された中空凸部２２～２５と、がそれぞれ対向して配置されるように、回路基板８の上面にクリックゴム１０を取り付ける。 First, the worker houses the external connection terminal 3 and the circuit board 8 inside the cover 1 and electrically connects the external connection terminal 3 and the circuit board 8 by soldering or the like. Next, the worker places the circuit board 8 so that the fixed contacts 4 to 7 formed on the circuit board 8 and the hollow convex portions 22 to 25 formed on the click rubber 10 face each other. Attach the click rubber 10 to the top of the.
　続いて、作業者は、クリックゴム１０の一端側（前方）に配置された２つの中空凸部２２，２３の上部にカム１１を載置し、可動接点２２ｄ，２３ｄが固定接点４，５とそれぞれ密着するまで、カム１１をクリックゴム１０に押し付ける。これにより、保持部２２ｃ，２３ｃの上面に形成された凹部２２ｅ，２３ｅ内に、押圧部１１ｂ，１１ｃの下面に形成された凸部１１ｄ，１１ｅが嵌合し、カム１１及びクリックゴム１０が一体化する。 Subsequently, the worker places the cam 11 on the top of the two hollow convex portions 22 and 23 disposed on one end side (forward) of the click rubber 10, and the movable contacts 22d and 23d become the fixed contacts 4 and 5, respectively. The cams 11 are pressed against the click rubber 10 until they are in close contact with each other. Thereby, the convex portions 11d and 11e formed on the lower surface of the pressing portions 11b and 11c fit into the concave portions 22e and 23e formed on the upper surfaces of the holding portions 22c and 23c, and the cam 11 and the click rubber 10 are integrated. Turn
　同様に、作業者は、クリックゴム１０の一端側（前方）に配置された２つの中空凸部２４，２５の上部にカム１２を載置し、可動接点２４ｄ，２５ｄが固定接点４，５とそれぞれ密着するまで、カム１２をクリックゴム１０に押し付ける。これにより、保持部２４ｃ，２５ｃの上面に形成された凹部２４ｅ，２５ｅ内に、押圧部１２ｂ，１２ｃの下面に形成された凸部１２ｄ，１２ｅが嵌合し、カム１２及びクリックゴム１０が一体化する。 Similarly, the operator places the cam 12 on the top of the two hollow convex portions 24 and 25 disposed on one end side (forward) of the click rubber 10, and the movable contacts 24d and 25d are fixed contacts 4 and 5, respectively. The cams 12 are pressed against the click rubber 10 until they are in close contact with each other. Thereby, the convex portions 12d and 12e formed on the lower surface of the pressing portions 12b and 12c are fitted in the concave portions 24e and 25e formed on the upper surfaces of the holding portions 24c and 25c, and the cam 12 and the click rubber 10 are integrated. Turn
　次に、作業者は、カバー１の側面に形成された凸部１ａをケース２の側面には形成された嵌合部２ａにそれぞれ嵌合させる。これにより、カバー１及びケース２が一体化する。 Next, the worker causes the convex portion 1 a formed on the side surface of the cover 1 to be fitted to the fitting portion 2 a formed on the side surface of the case 2. Thereby, the cover 1 and the case 2 are integrated.
　続いて、作業者は、操作つまみ１４を取付部１３上に載置する。図８は、取付部１３に載置された操作つまみ１４を右前方からみた拡大斜視図である。図８では、取付部１３の第１側面１３１と、操作つまみ１４の外装部１４１の右側面と、が省略されている。図９は、取付部１３に載置された操作つまみ１４を左前方からみた拡大斜視図である。図９では、取付部１３の第２側面１３２と、操作つまみ１４の外装部１４１の左側面と、が省略されている。 Subsequently, the operator places the operation knob 14 on the mounting portion 13. FIG. 8 is an enlarged perspective view of the operation knob 14 mounted on the mounting portion 13 as viewed from the right front. In FIG. 8, the first side surface 131 of the mounting portion 13 and the right side surface of the exterior portion 141 of the operation knob 14 are omitted. FIG. 9 is an enlarged perspective view of the operation knob 14 mounted on the mounting portion 13 as viewed from the left front. In FIG. 9, the second side surface 132 of the mounting portion 13 and the left side surface of the exterior portion 141 of the operation knob 14 are omitted.
　図８及び図９に示すように、操作つまみ１４を取付部１３上に載置する際、操作つまみ１４は、第１軸受部１４２ａ、第１嵌合部１４２ｂ、第２嵌合部１４３ｂ、及び第２嵌合部１４３ｂが、それぞれ取付部１３の第１軸部１３１ａ、第１抜け止め部１３１ｂ、第２軸部１３２ａ、及び第２抜け止め部１３２ｂの上方に位置するように配置される。 As shown in FIGS. 8 and 9, when the operation knob 14 is placed on the attachment portion 13, the operation knob 14 includes a first bearing portion 142a, a first fitting portion 142b, a second fitting portion 143b, and the like. The second fitting portion 143b is disposed above the first shaft portion 131a, the first retaining portion 131b, the second shaft portion 132a, and the second retaining portion 132b of the mounting portion 13, respectively.
　また、上述の通り、第１取付面１４２及び第２取付面１４３の下端は、上下方向の高さが一致する直線状であり、第１軸部１３１ａ、第１抜け止め部１３１ｂ、第２軸部１３２ａ、及び第２抜け止め部１３２ｂは、上端の上下方向の高さが一致するように形成されている。 Further, as described above, the lower ends of the first mounting surface 142 and the second mounting surface 143 are linear with the same height in the vertical direction, and the first shaft portion 131a, the first retaining portion 131b, the second shaft The portion 132a and the second retaining portion 132b are formed such that the heights of the upper ends in the vertical direction coincide with each other.
　したがって、操作つまみ１４を上記のように配置すると、操作つまみ１４は、第１取付面１４２の下端が第１軸部１３１ａ及び第１抜け止め部１３１ｂの上部に接触し、第２取付面１４３の下端が第２軸部１３２ａ及び第２抜け止め部１３２ｂの上部に接触した状態で、取付部１３上に載置される。すなわち、操作つまみ１４は、第１軸部１３１ａ、第１抜け止め部１３１ｂ、第２軸部１３２ａ、及び第２抜け止め部１３２ｂに支持された状態で、取付部１３上に載置される。このように、本実施形態によれば、操作つまみ１４を４点で支持した状態で取付部１３上に載置できるため、操作つまみ１４を取付部１３上に安定的に載置することができる。 Therefore, when the operation knob 14 is arranged as described above, the lower end of the first attachment surface 142 of the operation knob 14 contacts the upper portions of the first shaft portion 131 a and the first retaining portion 131 b. It mounts on the attaching part 13 in the state which the lower end contacted the upper part of the 2nd axial part 132a and the 2nd securing part 132b. That is, the operation knob 14 is mounted on the attachment portion 13 in a state of being supported by the first shaft portion 131a, the first retaining portion 131b, the second shaft portion 132a, and the second retaining portion 132b. As described above, according to the present embodiment, since the operation knob 14 can be mounted on the mounting portion 13 in a state of being supported at four points, the operation knob 14 can be stably mounted on the mounting portion 13 .
　なお、本実施形態において、操作つまみ１４の重心の前後方向の位置は、操作つまみ１４を取付部１３上に載置した際の、第１軸部１３１ａと操作つまみ１４との接点と、第１抜け止め部１３１ｂと操作つまみ１４との接点と、の間であるのが好ましい。言い換えると、操作つまみ１４の重心の前後方向の位置は、第１軸受部１４２ａの中心と、第１嵌合部１４２ｂの後端部と、の間であるのが好ましい。 In the present embodiment, the position of the center of gravity of the operation knob 14 in the front-rear direction is the contact point between the first shaft portion 131 a and the operation knob 14 when the operation knob 14 is placed on the mounting portion 13. Preferably, it is between the contact point between the retaining portion 131 b and the operation knob 14. In other words, the position of the center of gravity of the operation knob 14 in the front-rear direction is preferably between the center of the first bearing portion 142a and the rear end portion of the first fitting portion 142b.
　同様に、操作つまみ１４の重心の前後方向の位置は、操作つまみ１４を取付部１３上に載置した際の、第２軸部１３２ａと操作つまみ１４との接点と、第２抜け止め部１３２ｂと操作つまみ１４との接点と、の間であるのが好ましい。言い換えると、操作つまみ１４の重心の前後方向の位置は、第２軸受部１４３ａの中心と、第２嵌合部１４３ｂの後端部と、の間であるのが好ましい。 Similarly, the position of the center of gravity of the operation knob 14 in the front-rear direction is the contact point between the second shaft portion 132a and the operation knob 14 when the operation knob 14 is mounted on the mounting portion 13, and the second detachment prevention portion 132b. Preferably, it is between the point of contact and the contact point with the operation knob 14. In other words, it is preferable that the longitudinal position of the center of gravity of the operation knob 14 be between the center of the second bearing portion 143a and the rear end portion of the second fitting portion 143b.
　このような構成により、操作つまみ１４を取付部１３上に載置した際に、操作つまみ１４の重心が、操作つまみ１４を支持する４点の間に位置するため、操作つまみ１４を取付部１３上により安定的に載置することができる。 With such a configuration, when the operation knob 14 is mounted on the attachment portion 13, the center of gravity of the operation knob 14 is positioned between four points supporting the operation knob 14. It can be placed more stably on the top.
　操作つまみ１４の重心は、例えば、外装部１４１、第１取付面１４２、及び第２取付面１４３の厚さを変化させたり、第１取付面１４２及び第２取付面１４３を肉抜きしたりすることにより、調整できる。 The center of gravity of the operation knob 14 changes, for example, the thickness of the exterior portion 141, the first attachment surface 142, and the second attachment surface 143, or thins the first attachment surface 142 and the second attachment surface 143. Can be adjusted by
　作業者は、操作つまみ１４を取付部１３上に載置すると、操作つまみ１４を取付部１３に向かって押圧し、操作つまみ１４を下降させる。操作つまみ１４の下降中、第１取付面１４２は第１軸部１３１ａ及び第１抜け止め部１３１ｂに沿って湾曲し、第２取付面１４３は第２軸部１３２ａ及び第２抜け止め部１３２ｂに沿って湾曲する。第１取付面１４２及び第２取付面１４３が湾曲しやすいほど、操作つまみ１４を下降させる（取付部１３に取り付ける）ための要する押圧力は小さくなる。 When the operator places the operation knob 14 on the attachment portion 13, the operator presses the operation knob 14 toward the attachment portion 13 to lower the operation knob 14. During lowering of the operation knob 14, the first mounting surface 142 is curved along the first shaft portion 131a and the first retaining portion 131b, and the second mounting surface 143 is formed on the second shaft portion 132a and the second retaining portion 132b. Curve along. The easier the first attachment surface 142 and the second attachment surface 143 are curved, the smaller the pressing force required to lower the operation knob 14 (attach to the attachment portion 13).
　本実施形態では、上述の通り、第１軸部１３１ａ及び第１抜け止め部１３１ｂは、第１側面１３１からの高さが、上端から中央に向かって高くなるように形成させている。また、第２軸部１３２ａ及び第２抜け止め部１３２ｂは、第２側面１３２からの高さが、上端から中央に向かって高くなるように形成させている。このような構成により、操作つまみ１４を下降させると、第１取付面１４２の下端が第１軸部１３１ａ及び第１抜け止め部１３１ｂの表面にガイドされ、第２取付面１４３の下端が第２軸部１３２ａ及び第２抜け止め部１３２ｂの表面にガイドされる。本実施形態によれば、当該ガイドにより第１取付面１４２及び第２取付面１４３の下端を容易に湾曲させることができるため、操作つまみ１４を取付部１３に取り付けるために要する押圧力を小さくできる。 In the present embodiment, as described above, the first shaft portion 131a and the first retaining portion 131b are formed such that the height from the first side surface 131 is higher from the upper end toward the center. Further, the second shaft portion 132a and the second retaining portion 132b are formed such that the height from the second side surface 132 is higher from the upper end toward the center. With such a configuration, when the operation knob 14 is lowered, the lower end of the first attachment surface 142 is guided by the surfaces of the first shaft portion 131a and the first retaining portion 131b, and the lower end of the second attachment surface 143 is the second It is guided by the surface of the shaft portion 132a and the second retaining portion 132b. According to the present embodiment, since the lower ends of the first mounting surface 142 and the second mounting surface 143 can be easily bent by the guide, the pressing force required to attach the operation knob 14 to the mounting portion 13 can be reduced. .
　また、図８に示すように、第１取付面１４２は、その下端に、他の部分より薄く形成された肉薄部１４２ｃを設けられるのが好ましい。このような構成により、第１取付面１４２の下端が湾曲しやすくなるため、操作つまみ１４を取付部１３に取り付けるために要する押圧力を小さくできる。なお、肉薄部１４２ｃは、第１取付面１４２の下端の全体に形成されてもよいし、一部に形成されてもよい。肉薄部１４２ｃは、第１軸部１３１ａの前端部から第１抜け止め部１３１ｂの後端部まで形成されればよい。 Further, as shown in FIG. 8, it is preferable that the first attachment surface 142 be provided at its lower end with a thin portion 142 c formed thinner than the other portions. With such a configuration, the lower end of the first mounting surface 142 is easily bent, so that the pressing force required to attach the operation knob 14 to the mounting portion 13 can be reduced. The thin portion 142 c may be formed on the entire lower end of the first mounting surface 142 or may be formed on a part thereof. The thin portion 142c may be formed from the front end of the first shaft portion 131a to the rear end of the first retaining portion 131b.
　同様に、図９に示すように、第２取付面１４３は、その下端に、他の部分より薄く形成された肉薄部１４３ｃを設けられるのが好ましい。このような構成により、第２取付面１４３の下端が湾曲しやすくなるため、操作つまみ１４を取付部１３に取り付けるために要する押圧力を小さくできる。なお、肉薄部１４３ｃは、第２取付面１４３の下端の全体に形成されてもよいし、一部に形成されてもよい。肉薄部１４３ｃは、第２軸部１３２ａの前端部から第２抜け止め部１３２ｂの後端部まで形成されればよい。 Similarly, as shown in FIG. 9, the second mounting surface 143 is preferably provided at its lower end with a thin portion 143c formed thinner than the other portions. With such a configuration, the lower end of the second mounting surface 143 is easily bent, so that the pressing force required to attach the operation knob 14 to the mounting portion 13 can be reduced. The thin portion 143 c may be formed on the entire lower end of the second mounting surface 143 or may be formed on a part thereof. The thin portion 143c may be formed from the front end portion of the second shaft portion 132a to the rear end portion of the second retaining portion 132b.
　その後、操作つまみ１４が所定の取付位置まで下降すると、第１軸部１３１ａが第１軸受部１４２ａに嵌合し、第１抜け止め部１３１ｂが第１嵌合部１４２ｂに嵌合し、第２軸部１３２ａが第２軸受部１４３ａに嵌合し、第２抜け止め部１３２ｂが第２嵌合部１４３ｂに嵌合する。これにより、スイッチ装置１００の組み立てが完了する。 Thereafter, when the operation knob 14 is lowered to a predetermined mounting position, the first shaft portion 131a is fitted to the first bearing portion 142a, and the first retaining portion 131b is fitted to the first fitting portion 142b. The shaft portion 132a is fitted to the second bearing portion 143a, and the second retaining portion 132b is fitted to the second fitting portion 143b. Thereby, the assembly of the switch device 100 is completed.
　次に、本実施形態に係るスイッチ装置１００の動作について説明する。 Next, the operation of the switch device 100 according to the present embodiment will be described.
　図１０は、非操作状態におけるスイッチ装置１００を左方からみた断面図である。図１１は、非操作状態におけるスイッチ装置１００を後方からみた断面図である。非操作状態とは、操作つまみ１４の被操作時の状態のことである。 FIG. 10 is a cross-sectional view of the switch device 100 in the non-operation state as viewed from the left. FIG. 11 is a cross-sectional view of the switch device 100 in the non-operation state as viewed from the rear. The non-operation state is the state when the operation knob 14 is operated.
　操作つまみ１４の非操作時には、図１０及び図１１に示すように、クリックゴム１０の中空凸部２２～２５は、いずれも座屈しておらず、操作つまみ１４の押圧部１４１ｄ，１４１ｅは、クリックゴム１０の弾性力によって、カム１１，１２の受圧部１１ａ，１２ａに接触している。このとき、固定接点４～７と可動接点２２ｄ～２５ｄとは、それぞれ非接触状態に保たれている。また、第１抜け止め部１３１ｂ及び第２抜け止め部１３２ｂは、それぞれ第１嵌合部１４２ｂ及び第２嵌合部１４３ｂの中央部に位置している。 When the operation knob 14 is not operated, as shown in FIG. 10 and FIG. 11, none of the hollow convex portions 22 to 25 of the click rubber 10 is buckled, and the pressing portions 141 d and 141 e of the operation knob 14 click The elastic force of the rubber 10 contacts the pressure receiving portions 11 a and 12 a of the cams 11 and 12. At this time, the fixed contacts 4 to 7 and the movable contacts 22d to 25d are kept in non-contact with each other. Further, the first retaining portion 131b and the second retaining portion 132b are located at the central portions of the first fitting portion 142b and the second fitting portion 143b, respectively.
　図１２は、第１操作状態におけるスイッチ装置１００を左方からみた断面図である。図１３は、第１操作状態におけるスイッチ装置１００を後方からみた断面図である。第１操作状態は、操作つまみ１４の前端部が１段階下降するように操作された状態である。本実施形態において、第１操作は、固定接点４をオンにする操作に相当する。 FIG. 12 is a cross-sectional view of the switch device 100 in the first operation state as viewed from the left. FIG. 13 is a cross-sectional view of the switch device 100 in the first operation state as viewed from the rear. The first operation state is a state in which the front end portion of the operation knob 14 is operated to descend one step. In the present embodiment, the first operation corresponds to an operation of turning on the fixed contact 4.
　ユーザが第１軸部１３１ａ及び第２軸部１３２ａを軸として操作つまみ１４を前方に回転させると、図１２及び図１３に示すように、押圧部１４１ｄがカム１１を下方に押圧し、押圧部１４１ｅがカム１２から離間する。 When the user rotates the operation knob 14 forward about the first shaft portion 131a and the second shaft portion 132a, as shown in FIGS. 12 and 13, the pressing portion 141d presses the cam 11 downward, and the pressing portion 141 e separates from the cam 12.
　押圧部１４１ｄは、左右方向の中央より左側に設けられているため、中空凸部２３よりも中空凸部２２を強く押圧する。この結果、図１３に示すように、中空凸部２３より先に中空凸部２２が座屈し（操作つまみ１４の前端部が１段階下降し）、固定接点４と可動接点２２ｄとが接触して、固定接点４がオンになり、固定接点４のオン信号が外部接続端子３から出力される。中空凸部２２が座屈した際、当該座屈に伴うクリック感がカム１１を介して操作つまみ１４に伝達されるため、ユーザは固定接点４がオンになったことを感触で知ることができる。また、第１操作状態において、第１抜け止め部１３１ｂ及び第２抜け止め部１３２ｂは、それぞれ第１嵌合部１４２ｂ及び第２嵌合部１４３ｂの下部に位置している。 The pressing portion 141 d is provided on the left side of the center in the left-right direction, and thus presses the hollow convex portion 22 more strongly than the hollow convex portion 23. As a result, as shown in FIG. 13, the hollow convex portion 22 buckles earlier than the hollow convex portion 23 (the front end portion of the operation knob 14 descends by one step), and the fixed contact 4 and the movable contact 22 d come into contact with each other. The fixed contact 4 is turned on, and an on signal of the fixed contact 4 is output from the external connection terminal 3. When the hollow convex portion 22 is buckled, the click feeling associated with the buckling is transmitted to the operation knob 14 via the cam 11, so that the user can feel that the fixed contact 4 is turned on. . Furthermore, in the first operation state, the first retaining portion 131b and the second retaining portion 132b are located below the first fitting portion 142b and the second fitting portion 143b, respectively.
　第１操作状態において操作つまみ１４の押圧をやめると、中空凸部２２に形成された弾性変形部２２ｂの復元力によりカム１１及び操作つまみ１４が押し上げられ、スイッチ装置１００は非操作状態に復帰する。これにより、固定接点４と可動接点２２ｄとが離間し、固定接点４がオフになり、固定接点４のオフ信号が外部接続端子３から出力される。 When pressing of the operation knob 14 is stopped in the first operation state, the cam 11 and the operation knob 14 are pushed up by the restoring force of the elastic deformation portion 22b formed in the hollow convex portion 22, and the switch device 100 returns to the non-operation state. . As a result, the fixed contact 4 and the movable contact 22 d are separated, the fixed contact 4 is turned off, and an off signal of the fixed contact 4 is output from the external connection terminal 3.
　図１４は、第２操作状態におけるスイッチ装置１００を左方からみた断面図である。図１５は、第２操作状態におけるスイッチ装置１００を後方からみた断面図である。第２操作状態は、操作つまみ１４の前端部が２段階下降するように操作された状態である。本実施形態において、第２操作は、固定接点５をオンにする操作に相当する。 FIG. 14 is a cross-sectional view of the switch device 100 in the second operation state as viewed from the left. FIG. 15 is a cross-sectional view of the switch device 100 in the second operation state as viewed from the rear. The second operation state is a state in which the front end portion of the operation knob 14 is operated so as to be lowered by two steps. In the present embodiment, the second operation corresponds to an operation of turning on the fixed contact 5.
　ユーザが第１軸部１３１ａ及び第２軸部１３２ａを軸として操作つまみ１４を第１操作状態からさらに前方に回転させると、図１４及び図１５に示すように、押圧部１４１ｄがカム１１をさらに下方に押圧する。この結果、図１５に示すように、中空凸部２２と共に中空凸部２３が座屈し（操作つまみ１４の前端部がさらに１段階下降し）、固定接点５と可動接点２３ｄとが接触して、固定接点５がオンになり、固定接点５のオン信号が外部接続端子３から出力される。中空凸部２３が座屈した際、当該座屈に伴うクリック感がカム１１を介して操作つまみ１４に伝達されるため、ユーザは固定接点５がオンになったことを感触で知ることができる。 When the user rotates the operation knob 14 further forward from the first operation state with the first shaft portion 131a and the second shaft portion 132a as axes, as shown in FIG. 14 and FIG. Press downward. As a result, as shown in FIG. 15, the hollow convex portion 22 is buckled together with the hollow convex portion 22 (the front end of the operation knob 14 is further lowered by one step), and the fixed contact 5 and the movable contact 23 d come into contact with each other. The fixed contact 5 is turned on, and an on signal of the fixed contact 5 is output from the external connection terminal 3. When the hollow convex portion 23 is buckled, the click feeling associated with the buckling is transmitted to the operation knob 14 through the cam 11, so that the user can feel that the fixed contact 5 is turned on. .
　また、第２操作状態において、第１抜け止め部１３１ｂ及び第２抜け止め部１３２ｂは、その下端が、それぞれ第１嵌合部１４２ｂ及び第２嵌合部１４３ｂの下端に接触する。これにより、操作つまみ１４の押圧操作による第１軸部１３１ａ及び第２軸部１３２ａへの負荷が第１抜け止め部１３１ｂ及び第２抜け止め部１３２ｂにほぼ二分して分散される。これは、第１抜け止め部１３１ｂの下端及び第２抜け止め部１３２ｂの下端と、第１軸部１３１ａの下端及び第２軸部１３２ａの下端と、の上下方向の高さがほぼ一致するためである。結果として、操作つまみ１４の押圧操作により、第１軸部１３１ａ及び第２軸部１３２ａがそれぞれ第１軸受部１４２ａ及び第２軸受部１４３ａから抜ける、すなわち、操作つまみ１４が取付部１３から抜けることを抑制できる。 In the second operation state, the lower ends of the first retaining portion 131b and the second retaining portion 132b are in contact with the lower ends of the first fitting portion 142b and the second fitting portion 143b, respectively. As a result, the load on the first shaft portion 131a and the second shaft portion 132a by the pressing operation of the operation knob 14 is substantially divided into the first retaining portion 131b and the second retaining portion 132b and dispersed. This is because the vertical heights of the lower end of the first retaining portion 131b and the lower end of the second retaining portion 132b substantially coincide with the lower end of the first shaft portion 131a and the lower end of the second shaft portion 132a. It is. As a result, when the operation knob 14 is pressed, the first shaft portion 131a and the second shaft portion 132a come out of the first bearing portion 142a and the second bearing portion 143a, that is, the operation knob 14 comes out of the mounting portion 13 Can be suppressed.
　第２操作状態において操作つまみ１４の押圧をやめると、中空凸部２２に形成された弾性変形部２２ｂ及び中空凸部２３に形成された弾性変形部２３ｂの復元力によりカム１１及び操作つまみ１４が押し上げられ、スイッチ装置１００は非操作状態に復帰する。これにより、固定接点４と可動接点２２ｄとが離間し、固定接点４がオフになり、固定接点４のオフ信号が外部接続端子３から出力される。また、固定接点５と可動接点２３ｄとが離間し、固定接点５がオフになり、固定接点５のオフ信号が外部接続端子３から出力される。 When pressing of the operation knob 14 is stopped in the second operation state, the restoring force of the elastic deformation portion 22b formed in the hollow convex portion 22 and the elastic deformation portion 23b formed in the hollow convex portion 23 causes the cam 11 and the operation knob 14 to As a result, the switch device 100 returns to the non-operation state. As a result, the fixed contact 4 and the movable contact 22 d are separated, the fixed contact 4 is turned off, and an off signal of the fixed contact 4 is output from the external connection terminal 3. Further, the fixed contact 5 and the movable contact 23 d are separated, the fixed contact 5 is turned off, and an off signal of the fixed contact 5 is output from the external connection terminal 3.
　同様に、第３操作状態及び第４操作状態について説明する。第３操作状態は、操作つまみ１４の後端部が１段階下降するように操作された状態である。本実施形態において、第３操作は、固定接点７をオンにする操作に相当する。また、第４操作状態は、操作つまみ１４の後端部が２段階下降するように操作された状態である。本実施形態において、第４操作は、固定接点６をオンにする操作に相当する。 Similarly, the third operation state and the fourth operation state will be described. The third operation state is a state in which the rear end portion of the operation knob 14 is operated to descend one step. In the present embodiment, the third operation corresponds to an operation of turning on the fixed contact 7. In the fourth operation state, the rear end portion of the operation knob 14 is operated so as to be lowered by two steps. In the present embodiment, the fourth operation corresponds to an operation of turning on the fixed contact 6.
　ユーザが第１軸部１３１ａ及び第２軸部１３２ａを軸として操作つまみ１４を後方に回転させると、押圧部１４１ｅがカム１２を下方に押圧し、押圧部１４１ｄがカム１１から離間する。 When the user rotates the operation knob 14 rearward about the first shaft portion 131a and the second shaft portion 132a, the pressing portion 141e presses the cam 12 downward, and the pressing portion 141d separates from the cam 11.
　押圧部１４１ｅは、左右方向の中央より右側に設けられているため、中空凸部２４よりも中空凸部２５を強く押圧する。この結果、中空凸部２４より先に中空凸部２５が座屈し（操作つまみ１４の後端部が１段階下降し）、固定接点７と可動接点２５ｄとが接触して、固定接点７がオンになり、固定接点７のオン信号が外部接続端子３から出力される。中空凸部２５が座屈した際、当該座屈に伴うクリック感がカム１２を介して操作つまみ１４に伝達されるため、ユーザは固定接点７がオンになったことを感触で知ることができる。また、第３操作状態において、第１抜け止め部１３１ｂ及び第２抜け止め部１３２ｂは、それぞれ第１嵌合部１４２ｂ及び第２嵌合部１４３ｂの上部に位置している。 The pressing portion 141 e is provided on the right side of the center in the left-right direction, and thus presses the hollow convex portion 25 more strongly than the hollow convex portion 24. As a result, the hollow convex portion 25 buckles earlier than the hollow convex portion 24 (the rear end portion of the operation knob 14 descends by one step), and the fixed contact 7 and the movable contact 25 d come into contact, and the fixed contact 7 turns on. The on signal of the fixed contact 7 is output from the external connection terminal 3. When the hollow convex portion 25 is buckled, the click feeling associated with the buckling is transmitted to the operation knob 14 through the cam 12 so that the user can feel that the fixed contact 7 has been turned on. . Furthermore, in the third operation state, the first retaining portion 131b and the second retaining portion 132b are located above the first fitting portion 142b and the second fitting portion 143b, respectively.
　第３操作状態において操作つまみ１４の押圧をやめると、中空凸部２５に形成された弾性変形部２５ｂの復元力によりカム１２及び操作つまみ１４が押し上げられ、スイッチ装置１００は非操作状態に復帰する。これにより、固定接点７と可動接点２５ｄとが離間し、固定接点７がオフになり、固定接点７のオフ信号が外部接続端子３から出力される。 When pressing of the operation knob 14 is stopped in the third operation state, the cam 12 and the operation knob 14 are pushed up by the restoring force of the elastic deformation portion 25b formed in the hollow convex portion 25, and the switch device 100 returns to the non-operation state. . As a result, the fixed contact 7 and the movable contact 25 d are separated, the fixed contact 7 is turned off, and an off signal of the fixed contact 7 is output from the external connection terminal 3.
　ユーザが第１軸部１３１ａ及び第２軸部１３２ａを軸として操作つまみ１４を第３操作状態からさらに後方に回転させると、押圧部１４１ｅがカム１２をさらに下方に押圧する。この結果、中空凸部２５と共に中空凸部２４が座屈し（操作つまみ１４の後端部がさらに１段階下降し）、固定接点６と可動接点２４ｄとが接触して、固定接点６がオンになり、固定接点６のオン信号が外部接続端子３から出力される。中空凸部２４が座屈した際、当該座屈に伴うクリック感がカム１２を介して操作つまみ１４に伝達されるため、ユーザは固定接点６がオンになったことを感触で知ることができる。 When the user rotates the operation knob 14 further rearward from the third operation state with the first shaft portion 131a and the second shaft portion 132a as axes, the pressing portion 141e presses the cam 12 further downward. As a result, the hollow convex portion 25 is buckled together with the hollow convex portion 25 (the rear end portion of the operation knob 14 is further lowered by one step), and the fixed contact 6 and the movable contact 24 d come into contact with each other. The ON signal of the fixed contact 6 is output from the external connection terminal 3. When the hollow convex portion 24 is buckled, the click feeling associated with the buckling is transmitted to the operation knob 14 via the cam 12 so that the user can feel that the fixed contact 6 has been turned on. .
　また、第４操作状態において、第１抜け止め部１３１ｂ及び第２抜け止め部１３２ｂは、その上端が、それぞれ第１嵌合部１４２ｂ及び第２嵌合部１４３ｂの上端に接触する。これにより、操作つまみ１４の押圧操作による第１軸部１３１ａ及び第２軸部１３２ａへの負荷が分散される。結果として、操作つまみ１４の押圧操作により、第１軸部１３１ａ及び第２軸部１３２ａがそれぞれ第１軸受部１４２ａ及び第２軸受部１４３ａから抜ける、すなわち、操作つまみ１４が取付部１３から抜けることを抑制できる。 In the fourth operation state, the upper ends of the first retaining portion 131b and the second retaining portion 132b are in contact with the upper ends of the first fitting portion 142b and the second fitting portion 143b, respectively. Thereby, the load to the 1st axial part 131a and the 2nd axial part 132a by pressing operation of the operation knob 14 is disperse | distributed. As a result, when the operation knob 14 is pressed, the first shaft portion 131a and the second shaft portion 132a come out of the first bearing portion 142a and the second bearing portion 143a, that is, the operation knob 14 comes out of the mounting portion 13 Can be suppressed.
　第４操作状態において操作つまみ１４の押圧をやめると、中空凸部２４に形成された弾性変形部２４ｂ及び中空凸部２５に形成された弾性変形部２５ｂの復元力によりカム１２及び操作つまみ１４が押し上げられ、スイッチ装置１００は非操作状態に復帰する。これにより、固定接点６と可動接点２６ｄとが離間し、固定接点６がオフになり、固定接点６のオフ信号が外部接続端子３から出力される。また、固定接点７と可動接点２５ｄとが離間し、固定接点７がオフになり、固定接点７のオフ信号が外部接続端子３から出力される。 When pressing of the operation knob 14 is stopped in the fourth operation state, the restoring force of the elastic deformation portion 24b formed in the hollow convex portion 24 and the elastic deformation portion 25b formed in the hollow convex portion 25 causes the cam 12 and the operation knob 14 to As a result, the switch device 100 returns to the non-operation state. Thereby, the fixed contact 6 and the movable contact 26 d are separated, the fixed contact 6 is turned off, and an off signal of the fixed contact 6 is output from the external connection terminal 3. Further, the fixed contact 7 and the movable contact 25 d are separated, the fixed contact 7 is turned off, and an off signal of the fixed contact 7 is output from the external connection terminal 3.
　以上説明した通り、本実施形態によれば、第２操作状態及び第４操作状態において、第１抜け止め部１３１ｂ及び第２抜け止め部１３２ｂの端部が、それぞれ第１嵌合部１４２ｂ及び第２嵌合部１４３ｂの端部に接触する。これにより、操作つまみ１４の押圧操作による第１軸部１３１ａ及び第２軸部１３２ａへの負荷が分散される。結果として、操作つまみ１４の押圧操作により、第１軸部１３１ａ及び第２軸部１３２ａがそれぞれ第１軸受部１４２ａ及び第２軸受部１４３ａから抜ける、すなわち、操作つまみ１４が取付部１３から抜けることを抑制できる。 As described above, according to the present embodiment, in the second operation state and the fourth operation state, the end portions of the first retaining portion 131b and the second retaining portion 132b are respectively the first fitting portion 142b and the first fitting portion 142b. 2 Contact the end of the fitting portion 143b. Thereby, the load to the 1st axial part 131a and the 2nd axial part 132a by pressing operation of the operation knob 14 is disperse | distributed. As a result, when the operation knob 14 is pressed, the first shaft portion 131a and the second shaft portion 132a come out of the first bearing portion 142a and the second bearing portion 143a, that is, the operation knob 14 comes out of the mounting portion 13 Can be suppressed.
　また、本実施形態によれば、スイッチ装置１００の組み立て時において、操作つまみ１４を、その下端が４点で支持された状態で、取付部１３上に載置できる。すなわち、操作つまみ１４を取付部１３上に安定的に載置できる。結果として、産業用ロボットにより、操作つまみ１４を取付部１３上に載置する工程と、操作つまみ１４をケース２（取付部１３）に対して押圧する工程と、をそれぞれ容易に実行できる。すなわち、本実施形態に係るスイッチ装置１００は、産業用ロボットにより容易に組み立てることができる。 Further, according to the present embodiment, when the switch device 100 is assembled, the operation knob 14 can be placed on the mounting portion 13 with its lower end supported at four points. That is, the operation knob 14 can be stably mounted on the mounting portion 13. As a result, the step of mounting the operation knob 14 on the attachment portion 13 and the step of pressing the operation knob 14 against the case 2 (attachment portion 13) can be easily performed by the industrial robot.
