Next, a case where the switch device 10 is used will be described.
In the switch device 10, in the normal state, as shown in FIG. 2, the buffer protection member 15 is pushed out from the inside of the holding cylinder portion 24 of the main body case 2 by the spring force of the second spring member 26. At this time, the head 19 of the operating member 14 is pushed out toward the outside of the main body case 2 by the spring force of the first spring member 23, and is arranged at the first position.
すなわち、緩衝保護部材１５が第２ばね部材２６のばね力によって押し出された際には、図２に示すように、緩衝保護部材１５の内端部における当接部１５ａの外側面が筒状部材１３の鍔状部１７における外周部１７ａの内側面に当接し、緩衝保護部材１５の外周部に設けられた位置規制部１５ｂが本体ケース２の保持筒部２４の外端部から所定間隔（Ｓ２）だけ離れた位置に配置される。
That is, when the cushioning protection member 15 is pushed out by the spring force of the second spring member 26, as shown in FIG. 2, the outer surface of the contact portion 15a at the inner end portion of the cushioning protection member 15 is a tubular member. The position restricting portion 15b provided on the outer peripheral portion of the buffer protection member 15 comes into contact with the inner surface of the outer peripheral portion 17a of the flange-shaped portion 17 of the main body case 2 at a predetermined distance (S2) from the outer end portion of the holding cylinder portion 24 of the main body case 2. ) Is placed at a distance.
また、操作部材１４の頭部１９が第１ばね部材２３のばね力によって押し出された際には、図２に示すように、操作部材１４の軸部１８の内端部に設けられた抜止め部材２１が本体ケース２内に位置する筒状部１６の内端面に当接して、この軸部１８の内端部が時計モジュール６のスイッチ部２２の接点部２２ａから離れる。これにより、スイッチ部２２がオフ状態になる。この状態では、緩衝保護部材１５の外端部と操作部材１４の頭部１９の外端面とがほぼ同一面上に配置される。
Further, when the head portion 19 of the operating member 14 is pushed out by the spring force of the first spring member 23, as shown in FIG. 2, the retaining member provided at the inner end portion of the shaft portion 18 of the operating member 14 The member 21 comes into contact with the inner end surface of the tubular portion 16 located in the main body case 2, and the inner end portion of the shaft portion 18 is separated from the contact portion 22a of the switch portion 22 of the watch module 6. As a result, the switch unit 22 is turned off. In this state, the outer end portion of the buffer protection member 15 and the outer end surface of the head 19 of the operating member 14 are arranged on substantially the same surface.
そして、操作部材１４の頭部１９を押圧する際には、頭部１９よりも外径の大きい緩衝保護部材１５が頭部１９と共に押圧される。このときには、第２ばね部材２６のばね力が第１ばね部材２３のばね力よりも強く設定されていることにより、第２ばね部材２６のばね力に抗して緩衝保護部材１５を操作部材１４の頭部１９と共に押圧する。
Then, when the head 19 of the operating member 14 is pressed, the buffer protection member 15 having an outer diameter larger than that of the head 19 is pressed together with the head 19. At this time, since the spring force of the second spring member 26 is set stronger than the spring force of the first spring member 23, the buffer protection member 15 is operated by the operating member 14 against the spring force of the second spring member 26. Press with the head 19 of.
これにより、図３に示すように、操作部材１４の頭部１９よりも外径の大きい緩衝保護部材１５と共に操作部材１４の頭部１９がスライドすることで、操作部材１４の押し込み感覚が向上する。このため、緩衝保護部材１５が保持筒部２４でガイドされながら本体ケース２側に向けてスライドし、緩衝保護部材１５の位置規制部１５ｂが保持筒部２４の外端部に当接して位置規制される。
As a result, as shown in FIG. 3, the head 19 of the operating member 14 slides together with the buffer protection member 15 having an outer diameter larger than that of the head 19 of the operating member 14, so that the feeling of pushing the operating member 14 is improved. .. Therefore, the cushioning protection member 15 slides toward the main body case 2 side while being guided by the holding cylinder portion 24, and the position regulating portion 15b of the cushioning protection member 15 comes into contact with the outer end portion of the holding cylinder portion 24 to regulate the position.

At the same time, the head 19 of the operating member 14 slides toward the inside of the main body case 2 together with the cushioning protective member 15. At this time, as shown in FIG. 3, the shaft portion 18 of the operating member 14 slides in the tubular portion 16 of the tubular member 13, and the inner end portion of the shaft portion 18 projects into the main body case 2, and the watch module The contact spring 22b of the switch portion 22 of No. 6 is pressed toward the contact portion 22a, but since the slide length S2 of the buffer protection member 15 is shorter than the slide length S1 of the operation member 14, the inner end portion of the shaft portion 18 Does not turn on even if the switch portion 22 protrudes into the main body case 2.
この状態で、操作部材１４の頭部１９を第１ばね部材２３のばね力に抗して押圧する。このときには、図４に示すように、緩衝保護部材１５はスライドせず、操作部材１４のみがスライドし、頭部１９が第１ばね部材２３を圧縮させて筒状部材１３の鍔状部１７に接近すると共に、軸部１８の内端部が更に本体ケース２内に突出して、スイッチ部２２の接点ばね２２ｂを接点部２２ａに押し付けて接触させる。これにより、スイッチ部２２がオン状態になる。
In this state, the head 19 of the operating member 14 is pressed against the spring force of the first spring member 23. At this time, as shown in FIG. 4, the cushioning protection member 15 does not slide, only the operating member 14 slides, and the head 19 compresses the first spring member 23 into the collar-shaped portion 17 of the tubular member 13. As the shaft portion 18 approaches, the inner end portion of the shaft portion 18 further protrudes into the main body case 2, and the contact spring 22b of the switch portion 22 is pressed against the contact portion 22a to bring them into contact with each other. As a result, the switch unit 22 is turned on.
一方、スイッチ装置１０が通常状態のときに、緩衝保護部材１５が外部から衝撃を受けた際には、その衝撃に応じて緩衝保護部材１５が操作部材１４の頭部１９と共にスライドして、第２ばね部材２６を圧縮すると共に、頭部１９が第１ばね部材２３を圧縮する。これにより、衝撃が緩衝されると共に、緩衝保護部材１５によって操作部材１４の頭部１９が保護される。

As a result, the impact is buffered, and the head 19 of the operating member 14 is protected by the buffer protection member 15.
また、緩衝保護部材１５が外部から衝撃（緩衝保護部材１５の軸方向に対して垂直方向や斜め方向からの衝撃）を受けた際には、保持筒部２４が、ほぼ円筒状をなし、緩衝保護部材１５の軸方向の長さの半分ぐらいまで延出して設けられているので、緩衝保護部材１５が軸方向に対してねじれることなく、緩衝保護部材１５によって操作部材１４の頭部１９が保護される。
Further, when the buffer protection member 15 receives an impact from the outside (impact from a direction perpendicular to the axial direction of the buffer protection member 15 or an impact from an oblique direction), the holding cylinder portion 24 has a substantially cylindrical shape and cushions. Since the protective member 15 is provided so as to extend to about half the length in the axial direction, the head 19 of the operating member 14 is protected by the buffer protective member 15 without twisting in the axial direction. Will be done.
この場合、外部からの衝撃を緩衝しきれないときには、図３に示すように、緩衝保護部材１５が更にスライドして、緩衝保護部材１５の位置規制部１５ｂが保持筒部２４の外端部に当接して位置規制される。これにより、外部の衝撃を緩衝保護部材１５によって確実に受け止めて、スイッチ部２２が不用意にオンするのを確実に防ぐと共に、緩衝保護部材１５によって操作部材１４の頭部１９を確実にかつ良好に保護する。
In this case, when the impact from the outside cannot be completely buffered, as shown in FIG. 3, the buffer protection member 15 slides further, and the position regulating portion 15b of the buffer protection member 15 is attached to the outer end portion of the holding cylinder portion 24. The position is regulated by contact. As a result, the external impact is reliably received by the buffer protection member 15, the switch unit 22 is reliably prevented from being turned on carelessly, and the head 19 of the operation member 14 is reliably and satisfactorily received by the buffer protection member 15. To protect.
また、このときには、操作部材１４の軸部１８が緩衝保護部材１５と共にスライドして、軸部１８の内端部が本体ケース２内に突出するが、図３に示すように、時計モジュール６のスイッチ部２２がオン状態になることはない。このため、外部からの衝撃を受けても、軸部１８の内端部によってスイッチ部２２が誤動作したり破損したりすることがなく、スイッチ部２２および時計モジュール６を良好に保護することができる。
Further, at this time, the shaft portion 18 of the operating member 14 slides together with the buffer protection member 15, and the inner end portion of the shaft portion 18 projects into the main body case 2. As shown in FIG. 3, the watch module 6 The switch unit 22 is never turned on. Therefore, even if an impact is received from the outside, the switch portion 22 does not malfunction or be damaged by the inner end portion of the shaft portion 18, and the switch portion 22 and the clock module 6 can be satisfactorily protected. ..
このように、この腕時計のスイッチ装置１０によれば、貫通孔１１が設けられた腕時計ケース１の本体ケース２と、この本体ケース２の貫通孔１１に対してスライド可能に設けられた軸部１８、およびこの軸部１８の外端部に設けられて本体ケース２の外部に配置された頭部１９を備えた操作部材１４と、この操作部材１４の頭部１９の外周を覆った状態で、本体ケース２にスライド可能に設けられ、かつそのスライド長さＳ２が操作部材１４のスライド長Ｓ１さよりも短く設定された緩衝保護部材１５と、を備えていることにより、操作部材１４の操作性を向上させ、かつ耐衝撃性を確保することができる。
As described above, according to the switch device 10 of the wristwatch, the main body case 2 of the wristwatch case 1 provided with the through hole 11 and the shaft portion 18 slidably provided with respect to the through hole 11 of the main body case 2. , And an operating member 14 having a head 19 provided at the outer end of the shaft portion 18 and arranged outside the main body case 2, and a state of covering the outer periphery of the head 19 of the operating member 14.

It can be improved and impact resistance can be ensured.
すなわち、この腕時計のスイッチ装置１０では、操作部材１４の頭部１９を押し込む際に、操作部材１４の頭部１９と共に緩衝保護部材１５をスライドさせた上、操作部材１４のみをスライドさせて押し込むことができるので、操作部材１４の頭部１９の外径よりも大きい外径の緩衝保護部材１５を操作部材１４の頭部１９と共にスライドさせることができ、これにより操作部材１４の押し込み感覚を向上させることができるので、操作部材１４の操作性を向上させることができる。
That is, in the switch device 10 of this watch, when the head 19 of the operating member 14 is pushed in, the buffer protection member 15 is slid together with the head 19 of the operating member 14, and then only the operating member 14 is slid and pushed. Therefore, the buffer protection member 15 having an outer diameter larger than the outer diameter of the head 19 of the operating member 14 can be slid together with the head 19 of the operating member 14, thereby improving the pushing feeling of the operating member 14. Therefore, the operability of the operating member 14 can be improved.
また、この腕時計のスイッチ装置１０では、緩衝保護部材１５が外部から衝撃を受けた際に、緩衝保護部材１５が操作部材１４の頭部１９を覆った状態で、緩衝保護部材１５を頭部１９と共にスライドさせることができるので、緩衝保護部材１５によって衝撃を緩衝することができると共に、操作部材１４の頭部１９を良好に保護することができ、これにより耐衝撃性を確保することができる。
Further, in the switch device 10 of this wristwatch, when the buffer protection member 15 receives an impact from the outside, the buffer protection member 15 covers the head 19 of the operation member 14, and the buffer protection member 15 is placed on the head 19 of the operation member 14. Since it can be slid together with, the impact can be buffered by the buffer protection member 15, and the head 19 of the operation member 14 can be satisfactorily protected, whereby the impact resistance can be ensured.
この場合、本体ケース２は、その貫通孔１１に設けられた筒状部材１３と、緩衝保護部材１５がスライド可能に配置される保持筒部２４と、を備えていることにより、貫通孔１１に設けられた筒状部材１３によって操作部材１４を本体ケース２の貫通孔１１に対して確実にかつ良好に取り付けることができると共に、保持筒部２４によって緩衝保護部材１５をスライド可能な状態で本体ケース２に対して確実にかつ良好に取り付けることができる。

It can be attached securely and well to 2.
すなわち、筒状部材１３は、本体ケース２の貫通孔１１内に固定された筒状部１６と、本体ケース２の外面に配置された鍔状部１７と、を備えているので、筒状部１６内に操作部材１４の軸部１８をスライド可能な状態で確実にかつ良好に取り付けることができる。また、保持筒部２４は、緩衝保護部材１５の外周に位置した状態で、本体ケース２にその外部に突出して設けられているので、保持筒部２４の内部に緩衝保護部材１５をスライド可能な状態で確実にかつ良好に取り付けることができる。
That is, since the tubular member 13 includes a tubular portion 16 fixed in the through hole 11 of the main body case 2 and a flange-shaped portion 17 arranged on the outer surface of the main body case 2, the tubular portion 13 is provided. The shaft portion 18 of the operating member 14 can be securely and satisfactorily mounted in the 16 in a slidable state. Further, since the holding cylinder portion 24 is provided on the main body case 2 so as to project outward from the holding cylinder portion 24 in a state of being located on the outer periphery of the cushioning protection member 15, the cushioning protection member 15 can be slid inside the holding cylinder portion 24. It can be installed securely and well in the state.
この場合、緩衝保護部材１５は、その内端部に筒状部材１３の鍔状部１７の外周部１７ａに接離可能に当接する当接部１５ａが設けられ、外周部に保持筒部２４の外端部に接離可能に当接する位置規制部１５ｂが設けられていることにより、緩衝保護部材１５のスライド長さＳ２を精度良く正確に設定することができる。
In this case, the buffer protection member 15 is provided with an abutting portion 15a at its inner end that comes into contact with the outer peripheral portion 17a of the flange-shaped portion 17 of the tubular member 13 so as to be detachable, and the holding tubular portion 24 is provided at the outer peripheral portion. Since the position restricting portion 15b that comes into contact with the outer end portion in contact with each other is provided, the slide length S2 of the buffer protection member 15 can be set accurately and accurately.
すなわち、緩衝保護部材１５は、本体ケース２の外部に向けて押し出された際に、当接部１５ａが鍔状部１７の外周部１７ａに当接して、位置規制部１５ｂが保持筒部２４の外端部から所定間隔（Ｓ２）だけ離れ、本体ケース２の内部に向けて押し込まれた際に、位置規制部１５ｂが保持筒部２４の外端部に当接し、当接部１５ａが鍔状部１７の外周部１７ａから所定間隔（Ｓ２）だけ離れることにより、緩衝保護部材１５のスライド長さＳ２を精度良く正確に設定することができる。
That is, when the buffer protection member 15 is pushed out toward the outside of the main body case 2, the contact portion 15a comes into contact with the outer peripheral portion 17a of the flange-shaped portion 17, and the position regulating portion 15b of the holding cylinder portion 24 When separated from the outer end portion by a predetermined interval (S2) and pushed toward the inside of the main body case 2, the position regulating portion 15b comes into contact with the outer end portion of the holding cylinder portion 24, and the contact portion 15a has a brim shape. By separating the outer peripheral portion 17a of the portion 17 by a predetermined interval (S2), the slide length S2 of the buffer protection member 15 can be set accurately and accurately.
また、このスイッチ装置１０では、操作部材１４を本体ケース２の外部に向けて付勢する第１の付勢部材である第１ばね部材２３と、緩衝保護部材１５を本体ケース２の外部に向けて付勢する第２の付勢部材である第２ばね部材２６と、を備えていることにより、第１ばね部材２３のばね力によって操作部材１４を本体ケース２の外部に向けて押し出すことができ、また第２ばね部材２６のばね力によって緩衝保護部材１５を本体ケース２の外部に向けて押し出すことができる。
Further, in the switch device 10, the first spring member 23, which is the first urging member for urging the operating member 14 toward the outside of the main body case 2, and the buffer protection member 15 are directed toward the outside of the main body case 2. By providing the second spring member 26, which is the second urging member for urging, the operating member 14 can be pushed out of the main body case 2 by the spring force of the first spring member 23. The cushioning protection member 15 can be pushed out of the main body case 2 by the spring force of the second spring member 26.
このため、このスイッチ装置１０では、緩衝保護部材１５が外部から衝撃を受けた際に、緩衝保護部材１５がスライドしながら第２ばね部材２６を圧縮させると共に、緩衝保護部材１５のスライドに伴って操作部材１４の頭部１９がスライドして第１ばね部材２３を圧縮させるので、衝撃を良好に緩衝することができると共に、操作部材１４の頭部１９を確実にかつ良好に保護することができる。
Therefore, in this switch device 10, when the shock absorbing protection member 15 receives an impact from the outside, the cushioning protection member 15 slides to compress the second spring member 26, and the shock absorbing protection member 15 slides. Since the head 19 of the operating member 14 slides to compress the first spring member 23, the impact can be satisfactorily buffered and the head 19 of the operating member 14 can be reliably and satisfactorily protected. ..
また、このスイッチ装置１０では、操作部材１４の頭部１９を押し込む際に、第２ばね部材２６のばね力に抗して緩衝保護部材１５を押し込むことにより、この緩衝保護部材１５と共に操作部材１４の頭部１９を押し込むことができ、これにより緩衝保護部材１５の位置規制部１５ｂが保持筒部２４の外端部に当接して、緩衝保護部材１５のスライドを停止させた状態で、頭部１９を第１ばね部材２３のばね力に抗して更に押し込むことができるので、操作部材１４の押し込み感覚を向上させることができ、これにより操作部材１４の操作性を向上させることができる。
Further, in the switch device 10, when the head 19 of the operating member 14 is pushed, the buffer protecting member 15 is pushed against the spring force of the second spring member 26, so that the operating member 14 is pushed together with the buffer protecting member 15. The head 19 can be pushed in, whereby the position restricting portion 15b of the cushioning protection member 15 comes into contact with the outer end portion of the holding cylinder portion 24, and the head of the cushioning protection member 15 is stopped from sliding. Since 19 can be further pushed against the spring force of the first spring member 23, the pushing feeling of the operating member 14 can be improved, and thus the operability of the operating member 14 can be improved.
この場合、第２ばね部材２６は、そのばね力が第１ばね部材２３のばね力よりも強く設定されていることにより、第２ばね部材２６のばね力に抗して緩衝保護部材１５を操作部材１４の頭部１９と共に押圧すると、緩衝保護部材１５のスライドに伴って操作部材１４の頭部１９を確実にかつ良好にスライドさせることができ、緩衝保護部材１５のスライドが停止した状態で、第２ばね部材２６のばね力よりも軽い力で頭部１９を更に押し込むことができるので、操作部材１４の押し込み感覚を更に向上させることができ、これにより操作部材１４の操作性を、より一層、向上させることができる。
In this case, the second spring member 26 operates the buffer protection member 15 against the spring force of the second spring member 26 because the spring force thereof is set to be stronger than the spring force of the first spring member 23. When pressed together with the head 19 of the member 14, the head 19 of the operating member 14 can be reliably and satisfactorily slid along with the slide of the buffer protection member 15, and the slide of the buffer protection member 15 is stopped. Since the head 19 can be further pushed with a force lighter than the spring force of the second spring member 26, the pushing feeling of the operating member 14 can be further improved, thereby further improving the operability of the operating member 14. , Can be improved.
また、第２ばね部材２６は、リング形状の皿ばねであることにより、構造が簡単で、低価格を図ることができると共に、設置スペースのコンパクト化を図ることができ、これにより緩衝保護部材１５の内端部とこれに対応する本体ケース２の保持溝２５内における軸方向の内端面との間の僅かな隙間に効率良く良好に設置することができる。
Further, since the second spring member 26 is a ring-shaped disc spring, the structure is simple, the price can be reduced, and the installation space can be made compact, whereby the buffer protection member 15 can be achieved. It can be efficiently and satisfactorily installed in a slight gap between the inner end portion of the main body case 2 and the inner end surface in the axial direction in the holding groove 25 of the main body case 2 corresponding thereto.
また、このスイッチ装置１０では、緩衝保護部材１５が本体ケース２の外部に押し出された際に、その外端面と操作部材１４の頭部１９の外端面とがほぼ同一面上に位置することにより、外部からの衝撃を、操作部材１４の頭部１９が受けることがなく、緩衝保護部材１５で受け止めることができるので、この緩衝保護部材１５によって操作部材１４を確実にかつ良好に保護することができる。
Further, in the switch device 10, when the buffer protection member 15 is pushed out of the main body case 2, the outer end surface thereof and the outer end surface of the head 19 of the operation member 14 are located on substantially the same surface. Since the head 19 of the operating member 14 does not receive the impact from the outside and can be received by the buffer protecting member 15, the buffer protecting member 15 can reliably and satisfactorily protect the operating member 14. it can.
さらに、このスイッチ装置１０では、本体ケース２内に設けられて、操作部材１４が緩衝保護部材１５のスライド長さＳ２よりも長いスライド長さＳ１で押し込まれた際に、オン動作するスイッチ部２２を備えていることにより、外部から衝撃を受けて緩衝保護部材１５が操作部材１４と共にスライドして押し込まれても、操作部材１４がスイッチ部２２をオン状態にさせないようにすることができ、これにより外部からの衝撃によるスイッチ部２２の誤動作およびスイッチ部２２の破損を確実に防ぐことができる。
Further, in the switch device 10, the switch unit 22 is provided in the main body case 2 and operates on when the operating member 14 is pushed in with a slide length S1 longer than the slide length S2 of the buffer protection member 15. The operation member 14 can prevent the switch portion 22 from being turned on even if the buffer protection member 15 is slid and pushed together with the operation member 14 due to an impact from the outside. As a result, malfunction of the switch unit 22 and damage to the switch unit 22 due to an external impact can be reliably prevented.
また、このスイッチ装置１０における操作部材１４のスライド長さＳ１は、操作部材１４が押し出された第１の位置と操作部材１４が押し込まれてスイッチ部２２がオン状態になった第２の位置との間の長さに設定され、緩衝保護部材１５のスライド長さＳ２は、緩衝保護部材１５が押し出されてその外端部と操作部材１４の外端面とがほぼ同一面上に位置する第１の位置と緩衝保護部材１５が操作部材１４と共に押し込まれてスイッチ部２２がオン状態にならない第３の位置との間の長さに設定されていることにより、操作部材１４の操作性が良く、かつ外部からの衝撃によるスイッチ部２２の誤動作およびスイッチ部２２の破損を確実に防ぐことができる。
Further, the slide length S1 of the operation member 14 in the switch device 10 is a first position where the operation member 14 is pushed out and a second position where the operation member 14 is pushed in and the switch portion 22 is turned on. The slide length S2 of the cushioning protection member 15 is set to a length between the two, and the cushioning protection member 15 is extruded so that the outer end portion thereof and the outer end surface of the operating member 14 are located on substantially the same surface. The operability of the operating member 14 is good because the length is set between the position of the button and the third position where the buffer protection member 15 is pushed together with the operating member 14 and the switch portion 22 is not turned on. Moreover, it is possible to reliably prevent malfunction of the switch unit 22 and damage to the switch unit 22 due to an external impact.
すなわち、このスイッチ装置１０では、緩衝保護部材１５のスライド長さＳ２が操作部材１４のスライド長さＳ１よりも短いため、外部から衝撃を受けて緩衝保護部材１５が操作部材１４と共にスライドして押し込まれても、操作部材１４がスイッチ部２２をオン状態にさせないようにすることができ、これにより外部からの衝撃によるスイッチ部２２の誤動作およびスイッチ部２２の破損を確実に防ぐことができる。
That is, in this switch device 10, since the slide length S2 of the buffer protection member 15 is shorter than the slide length S1 of the operation member 14, the buffer protection member 15 slides and is pushed in together with the operation member 14 by receiving an impact from the outside. Even so, the operating member 14 can prevent the switch unit 22 from being turned on, thereby reliably preventing malfunction of the switch unit 22 and damage to the switch unit 22 due to an external impact.
また、このスイッチ装置１０では、操作部材１４によってスイッチ部２２をオン動作させる際に、まず、緩衝保護部材１５を操作部材１４と共に押し込んで、操作部材１４の軸部１８の内端部をスイッチ部２２に接近させ、この状態で操作部材１４のみを更に押し込んで、スイッチ部２２をオン動作させることができるので、操作部材１４の押し込み感覚を向上させることができ、これにより操作部材１４の操作性が良く、確実にかつ良好にスイッチ部２２をオン動作させることができる。
Further, in the switch device 10, when the switch portion 22 is turned on by the operation member 14, the buffer protection member 15 is first pushed together with the operation member 14, and the inner end portion of the shaft portion 18 of the operation member 14 is pressed into the switch portion. Since the switch unit 22 can be turned on by approaching 22 and further pushing only the operating member 14 in this state, the pushing feeling of the operating member 14 can be improved, whereby the operability of the operating member 14 can be improved. The switch unit 22 can be turned on reliably and satisfactorily.
