The non-circular hole 22a is configured to project and retract toward the case body 8 side. A stopper portion 23a is provided at an end portion of the slide connecting portion 23, that is, an end portion on the outer side of the case body 8.

このストッパ部23aは、図3および図4に示すように、外形が本体軸22の非円形孔部22aと同じ四角形などの多角形や楕円などの非円形状に形成されている。これにより、ストッパ部23aは、本体軸22の非円形孔部22a内をスライドすると共に、本体軸22と共に一体的に回転するように構成されている。 As shown in FIGS. 3 and 4, the stopper portion 23a is formed in a non-circular shape such as a polygonal shape such as a quadrangle or an ellipse similar to the non-circular hole portion 22a of the main body shaft 22 in its outer shape. Accordingly, the stopper portion 23a is configured to slide in the non-circular hole portion 22a of the main body shaft 22 and rotate integrally with the main body shaft 22.

また、このストッパ部23aは、図3および図4に示すように、ケース本体8側に位置する本体軸22の非円形孔部22aの内端部に設けられた抜止め部22cに接離可能に当接するように構成されている。これにより、ストッパ部23aは、抜止め部22cによってスライド連結部23が本体軸22の非円形孔部22a内からケース本体8側に抜け出して脱落しないように構成されている。 Further, as shown in FIGS. 3 and 4, the stopper portion 23a can be brought into contact with and separated from the retaining portion 22c provided at the inner end portion of the non-circular hole portion 22a of the body shaft 22 located on the case body 8 side. Is configured to abut. Thereby, the stopper portion 23a is configured so that the slide coupling portion 23 does not come out from the inside of the non-circular hole portion 22a of the main body shaft 22 toward the case body 8 side by the retaining portion 22c.

この場合、本体軸22の内部には、図3および図4に示すように、スライド連結部23をケース本体8の内部側に向けて付勢するコイルばね26が設けられている。このコイルばね26は、一端部がスライド連結部23に押し当てられ、他端部がケース本体8の外部側に位置する本体軸22の円形孔部22bの奥側の端部に押し当てられた状態で、本体軸22の内部に配置されている。 In this case, as shown in FIGS. 3 and 4, a coil spring 26 that urges the slide connecting portion 23 toward the inside of the case body 8 is provided inside the body shaft 22. One end of the coil spring 26 is pressed against the slide coupling portion 23, and the other end thereof is pressed against an end portion on the inner side of the circular hole portion 22b of the main body shaft 22 located outside the case body 8. In this state, it is arranged inside the main body shaft 22.

操作軸24は、図3および図4に示すように、本体軸22内にスライド可能に配置されたスライド連結部23の外径、つまりケース本体8の貫通孔11の小径孔11aの内径よりも外径が小さい棒状に形成されている。このため、ケース本体8は、貫通孔11の小径孔11aの内径が操作軸24の挿入可能な最小限の大きさで小さく形成されることにより、ケース本体8の上下方向の長さ(厚み)が短く(薄く)形成されている。 As shown in FIGS. 3 and 4, the operating shaft 24 is larger than the outer diameter of the slide connecting portion 23 slidably arranged in the body shaft 22, that is, the inner diameter of the small diameter hole 11a of the through hole 11 of the case body 8. It is formed in a rod shape with a small outer diameter. Therefore, the case body 8 is formed such that the inner diameter of the small-diameter hole 11a of the through hole 11 is as small as the minimum size into which the operation shaft 24 can be inserted, so that the length (thickness) of the case body 8 in the vertical direction is increased. Is short (thin).

この操作軸24は、図3および図4に示すように、一端部がスライド連結部23に取り付けられ、他端部がケース本体8の貫通孔11の小径孔11aを通してケース本体8内の時計モジュール7の内部にスライドおよび回転可能な状態で配置されるように構成されている。これにより、操作軸24は、本体軸22の非円形孔部22a内に配置されたスライド連結部23のスライド動作に伴って時計モジュール7内でスライドすると共に、スライド連結部23の回転動作に伴って時計モジュール7内で回転するように構成されている。 As shown in FIGS. 3 and 4, one end of this operation shaft 24 is attached to the slide connecting portion 23, and the other end is passed through the small-diameter hole 11a of the through hole 11 of the case body 8 into the timepiece module inside the case body 8. It is configured so as to be slidably and rotatably arranged in the inside of 7. As a result, the operating shaft 24 slides in the timepiece module 7 as the slide connecting portion 23 arranged in the non-circular hole portion 22a of the main body shaft 22 slides, and the slide connecting portion 23 rotates. The clock module 7 is configured to rotate.

すなわち、この操作軸24は、図示しないが、スライド連結部23が本体軸22および頭部21と共に腕時計ケース1の外部に向けて引き出されて、時計モジュール7の内部でスライドした際に、時計モジュール7の時刻修正を可能な状態にし、この状態でスライド連結部23の回転動作に伴って時計モジュール7内で回転すると、時計モジュール7の時刻修正を実行させるように構成されている。 In other words, although not shown, the operation shaft 24 is pulled out toward the outside of the wristwatch case 1 by the slide connecting portion 23 together with the main body shaft 22 and the head 21, and slides inside the timepiece module 7. 7 is set in a state in which the time can be adjusted, and in this state, when the slide connecting portion 23 is rotated in the timepiece module 7, the time adjustment of the timepiece module 7 is executed.

一方、頭部21は、図2〜図4に示すように、本体軸22の外端部に一体に設けられている。この頭部21は、外径がロック部材12の固定部14における中心部の外径よりも少し大きい円形状に形成されている。すなわち、この頭部21は、外径の半径が貫通孔11の中心線からケース本体8の下面までの長さよりも少し長く、かつ貫通孔11の中心線から裏蓋6の下面までの長さよりも少し短い大きさの円形状に形成されている。 On the other hand, the head portion 21 is integrally provided on the outer end portion of the main body shaft 22 as shown in FIGS. The head portion 21 is formed in a circular shape whose outer diameter is slightly larger than the outer diameter of the central portion of the fixed portion 14 of the lock member 12. That is, the outer diameter of the head portion 21 is slightly longer than the length from the center line of the through hole 11 to the lower surface of the case body 8, and the length from the center line of the through hole 11 to the lower surface of the case back 6 is smaller than that. Is also formed into a circular shape with a slightly shorter size.

また、この頭部21は、図2〜図4に示すように、内部に本体軸22の外径よりも大きく、かつロック部15の外径とほぼ同じ大きさのリング状の凹部21aが設けられた構造になっている。この場合、頭部21の凹部21a内における奥側には、リング状の緩衝材27が凹部21aの奥側の内端面に押し当てられた状態で配置されている。 Further, as shown in FIGS. 2 to 4, the head portion 21 is provided internally with a ring-shaped recess 21a having a diameter larger than the outer diameter of the main body shaft 22 and substantially the same as the outer diameter of the lock portion 15. It has a special structure. In this case, a ring-shaped cushioning material 27 is arranged on the inner side of the recess 21a of the head portion 21 while being pressed against the inner end surface of the inner side of the recess 21a.

また、頭部21の凹部21aの内周面には、図3および図4に示すように、ロック部15の雄ねじ部15aに螺合する雌ねじ部21bが設けられている。これにより、頭部21は、ケース本体8の内部に向けて押し込まれた状態で、一方向に回転された際に、雌ねじ部21bがロック部材12のロック部15の雄ねじ部15aに螺合するように構成されている。 In addition, as shown in FIGS. 3 and 4, a female screw portion 21b that is screwed into the male screw portion 15a of the lock portion 15 is provided on the inner peripheral surface of the recess 21a of the head portion 21. As a result, when the head portion 21 is pushed toward the inside of the case body 8 and is rotated in one direction, the female screw portion 21b is screwed into the male screw portion 15a of the lock portion 15 of the lock member 12. Is configured.

また、この頭部21は、図3および図4に示すように、雌ねじ部21bがロック部材12のロック部15の雄ねじ部15aに螺合して締め付けられた際に、ロック部15と頭部21の凹部21aの内端面との間に挟まれた緩衝材27を弾性変形させた状態で、ロック部15にロックされるように構成されている。これら頭部21の雌ねじ部21bとロック部15の雄ねじ部15aとによって、ロック機構が構成されている。 In addition, as shown in FIGS. 3 and 4, the head portion 21 and the head portion 21 when the female screw portion 21b is screwed into the male screw portion 15a of the lock portion 15 of the lock member 12 and tightened. The buffer member 27 sandwiched between the inner end surface of the concave portion 21a of 21 and the buffer member 27 is elastically deformed and is locked by the lock portion 15. The female screw portion 21b of the head portion 21 and the male screw portion 15a of the lock portion 15 constitute a lock mechanism.

これにより、操作部材13は、図4に示すように、通常の状態のときに、操作軸24が時計モジュール7内に位置規制され、スライド連結部23が本体軸22の非円形孔部22a内からケース本体8側に押し出されて、本体軸22がコイルばね26のばね力によってケース本体8の外部に押し出され、スライド連結部23のストッパ部23aが本体軸22の抜け止め部22cに当接するように構成されている。 As a result, as shown in FIG. 4, in the operating member 13, the operating shaft 24 is positionally regulated in the timepiece module 7 in the normal state, and the slide connecting portion 23 is in the non-circular hole portion 22 a of the main body shaft 22. Is pushed out to the case body 8 side, the body shaft 22 is pushed out of the case body 8 by the spring force of the coil spring 26, and the stopper portion 23a of the slide coupling portion 23 abuts on the retaining portion 22c of the body shaft 22. Is configured.

また、この操作部材13は、図4に示す通常の状態で、頭部21をケース本体8の内部に向けて押し込んでロックする際に、頭部21と共に本体軸22がコイルばね26のばね力に抗してスライドし、このスライドに伴ってスライド連結部23が本体軸22の非円形孔部22a内に押し込まれるように構成されている。 Further, in the operation member 13 in the normal state shown in FIG. 4, when the head portion 21 is pushed toward the inside of the case body 8 and locked, the body shaft 22 together with the head portion 21 has a spring force of the coil spring 26. The slide connecting portion 23 is configured to be pushed into the non-circular hole portion 22a of the main body shaft 22 along with the slide.

また、この操作部材13は、図4に示すように、スライド連結部23が本体軸22の非円形孔部22a内に押し込まれた状態で、頭部21を一方向に回転させて、頭部21の雌ねじ部21bをロック部材12の雄ねじ部15aに螺合させる際に、本体軸22がコイルばね26のばね力に抗してケース本体8の内部側に向けてスライドするように構成されている。 In addition, as shown in FIG. 4, the operating member 13 rotates the head portion 21 in one direction with the slide connecting portion 23 being pushed into the non-circular hole portion 22a of the main body shaft 22 to move the head portion. When the female screw portion 21b of the screw 21 is screwed into the male screw portion 15a of the lock member 12, the main body shaft 22 is configured to slide toward the inner side of the case main body 8 against the spring force of the coil spring 26. There is.

この場合、操作部材13は、図3および図4に示すように、ロック部材12の雄ねじ部15aに対する頭部21の雌ねじ部21bの螺合に伴って、コイルばね26のばね力に抗して本体軸22がケース本体8の内部側に向けてスライドする際に、時計モジュール7内に位置規制された状態の操作軸24によって、スライド連結部23が本体軸22のスライドに伴って本体軸22内の非円形孔部22a内に徐々に押し込まれて、ストッパ部23aが本体軸22の抜止め部22cから徐々に離れるように構成されている。 In this case, as shown in FIGS. 3 and 4, the operation member 13 resists the spring force of the coil spring 26 as the female screw portion 21b of the head portion 21 is screwed into the male screw portion 15a of the lock member 12. When the main body shaft 22 slides toward the inner side of the case main body 8, the slide connecting portion 23 slides along with the main body shaft 22 by the operation shaft 24 whose position is restricted in the timepiece module 7. The stopper portion 23a is gradually pushed into the inner non-circular hole portion 22a so that the stopper portion 23a is gradually separated from the retaining portion 22c of the main body shaft 22.

また、この操作部材13は、図3に示すように、頭部21が一方向に回転する際に、頭部21の回転に伴ってスライド連結部23のストッパ部23aが本体軸22と共に回転し、このスライド連結部23の回転と共に操作軸24が回転しながら、ロック部材12の雄ねじ部15aに対する頭部21の雌ねじ部21bの螺合が進んで、頭部21がロック部15にロックされるように構成されている。 Further, as shown in FIG. 3, in the operation member 13, when the head 21 rotates in one direction, the stopper portion 23 a of the slide coupling portion 23 rotates together with the main body shaft 22 as the head 21 rotates. While the slide connecting portion 23 rotates, the operation shaft 24 rotates, and the screw engagement of the female screw portion 21b of the head portion 21 with the male screw portion 15a of the lock member 12 advances, so that the head portion 21 is locked by the lock portion 15. Is configured.

一方、この操作部材13は、図3および図4に示すように、頭部21が一方向と反対方向に回転されて、ロック部15の雄ねじ部15aに対する雌ねじ部21bの螺合が外れると、雄ねじ部15aに対する雌ねじ部21bのロックが解除され、本体軸22内のコイルばね26のばね力によって本体軸22が頭部21と共に腕時計ケース1の外部に向けて押し出されるように構成されている。 On the other hand, as shown in FIGS. 3 and 4, in the operating member 13, when the head portion 21 is rotated in the opposite direction to the one direction, and the female screw portion 21b is disengaged from the male screw portion 15a of the lock portion 15, The lock of the female screw portion 21b with respect to the male screw portion 15a is released, and the body shaft 22 is pushed out toward the outside of the wristwatch case 1 together with the head 21 by the spring force of the coil spring 26 in the body shaft 22.

すなわち、この操作部材13は、図4に示すように、頭部21を反対方向に回転させて、ロック部材12の雄ねじ部15aに対する頭部21の雌ねじ部21bの螺合を緩めて、ロック部15による頭部21のロックを解除する際に、コイルばね26のばね力によって本体軸22が頭部21と共にケース本体8の外部に向けて徐々に押し出されながら、スライド連結部23が本体軸22の非円形孔部22a内から徐々に引き出されて、ストッパ部23aが抜止め部22cに徐々に近づくように構成されている。 That is, as shown in FIG. 4, the operation member 13 rotates the head portion 21 in the opposite direction to loosen the screw engagement of the female screw portion 21b of the head portion 21 with the male screw portion 15a of the lock member 12 to lock the lock portion. When the lock of the head portion 21 by 15 is released, while the body shaft 22 is gradually pushed out toward the outside of the case body 8 together with the head portion 21 by the spring force of the coil spring 26, the slide connecting portion 23 causes the body shaft 22 to move. The stopper portion 23a is gradually pulled out from the non-circular hole portion 22a, and the stopper portion 23a gradually approaches the retaining portion 22c.

この場合、操作部材13は、図4に示すように、ロック部材12の雄ねじ部15aに対する頭部21の雌ねじ部21bの螺合が外れて、ロック部15による頭部21のロックが解除された際に、コイルばね26のばね力によって本体軸22が頭部21と共にケース本体8の外部に向けて押し出されて、スライド連結部23が本体軸22の非円形孔部22a内から引き出されて、ストッパ部23aが本体軸22の抜止め部22cに当接するように構成されている。 In this case, in the operation member 13, as shown in FIG. 4, the female screw portion 21b of the head portion 21 is unscrewed from the male screw portion 15a of the lock member 12, and the lock of the head portion 21 by the lock portion 15 is released. At this time, the main body shaft 22 is pushed out toward the outside of the case main body 8 together with the head portion 21 by the spring force of the coil spring 26, and the slide connecting portion 23 is pulled out from the inside of the non-circular hole portion 22 a of the main body shaft 22, The stopper portion 23a is configured to come into contact with the retaining portion 22c of the main body shaft 22.

さらに、この操作部材13は、図4に示すように、コイルばね26のばね力によって本体軸22が頭部21と共にケース本体8の外部に向けて押し出されて、スライド連結部23が本体軸22の抜止め部22cに当接した状態で、頭部21が更にケース本体8の外部に引き出された際に、操作部材13の操作軸24が本体軸22と共に時計モジュール7内で引き出される方向にスライドすると共に、操作部材13の頭部21の回転操作に伴って操作軸24が時計モジュール7内で回転するように構成されている。 Further, in the operating member 13, as shown in FIG. 4, the main body shaft 22 is pushed out toward the outside of the case main body 8 together with the head portion 21 by the spring force of the coil spring 26, and the slide connecting portion 23 is moved to the main body shaft 22. When the head portion 21 is further pulled out of the case body 8 in the state of being in contact with the retaining portion 22c, the operation shaft 24 of the operating member 13 is pulled out in the timepiece module 7 together with the body shaft 22. While being slid, the operation shaft 24 is configured to rotate within the timepiece module 7 as the head 21 of the operation member 13 is rotated.

すなわち、この操作部材13は、ロック部15による頭部21のロックが解除された状態で、操作軸24が更に引き出されて時計モジュール7の内部でスライドした際に、時計モジュール7を時刻修正可能な状態にし、この状態で頭部21の回転操作に伴って操作軸24が時計モジュール7内で回転すると、時計モジュール7の時刻修正が実行されるように構成されている。 That is, the operating member 13 can correct the time of the timepiece module 7 when the operation shaft 24 is further pulled out and slid inside the timepiece module 7 in a state where the lock of the head portion 21 by the lock portion 15 is released. In this state, when the operation shaft 24 rotates in the timepiece module 7 in accordance with the rotation operation of the head portion 21, the time adjustment of the timepiece module 7 is executed.

次に、この腕時計のスイッチ装置4の作用について説明する。
このスイッチ装置4を組み立てる場合には、まず、ケース本体8の外面にロック部材12を取り付ける。このときには、予め、ロック部材12の挿入孔12a内に複数の防水パッキン25を取り付けると共に、ロック部材12の凸部17の外周に防水部材18を取り付ける。この状態で、凸部17をケース本体8の外周に設けられた台座部8aの凹部8b内に挿入させて、防水部材18を凸部17の外周面と凹部8bの内周面との間に挟み付ける。
Next, the operation of the switch device 4 of this wristwatch will be described.
When assembling the switch device 4, first, the lock member 12 is attached to the outer surface of the case body 8. At this time, a plurality of waterproof packings 25 are attached to the inside of the insertion hole 12a of the lock member 12 and the waterproof member 18 is attached to the outer periphery of the convex portion 17 of the lock member 12 in advance. In this state, the convex portion 17 is inserted into the concave portion 8b of the pedestal portion 8a provided on the outer periphery of the case body 8, and the waterproof member 18 is provided between the outer peripheral surface of the convex portion 17 and the inner peripheral surface of the concave portion 8b. Sandwich.

この状態で、ロック部材12の固定部14をケース本体8の台座部8aに固定する。このときには、固定部14の両側部に設けられたねじ挿入孔14aを台座部8aの各ねじ穴8cにそれぞれ対応させ、この状態で固定部14の各ねじ挿入孔14aを通して複数のねじ部材16を台座部8aの各ねじ穴8cに螺合させて締め付ける。ことにより、ケース本体8の台座部8aに固定部14が固定され、ロック部材12がケース本体8の外面に取り付けられる。 In this state, the fixing portion 14 of the lock member 12 is fixed to the pedestal portion 8a of the case body 8. At this time, the screw insertion holes 14a provided on both sides of the fixing portion 14 are made to correspond to the respective screw holes 8c of the pedestal portion 8a, and in this state, the plurality of screw members 16 are passed through the respective screw insertion holes 14a of the fixing portion 14. The screw holes 8c of the pedestal portion 8a are screwed together and tightened. As a result, the fixing portion 14 is fixed to the pedestal portion 8 a of the case body 8, and the lock member 12 is attached to the outer surface of the case body 8.

この場合、固定部14が複数のねじ部材16によって締め付けられて台座部8aに固定される際には、凸部17の外周面と凹部8bの内周面との間に挟まれた防水部材18が固定部14の内面に押し当てられることにより、ケース本体8の台座部8aにロック部材12が位置決めされる。すなわち、固定部14が複数のねじ部材16によって台座部8aに固定される際には、台座部8aに対する固定部14の取付状態、つまり固定部14の上下左右方向の傾きが防水部材18の弾力によって調整される。 In this case, when the fixing portion 14 is tightened by the plurality of screw members 16 and fixed to the pedestal portion 8a, the waterproof member 18 sandwiched between the outer peripheral surface of the convex portion 17 and the inner peripheral surface of the concave portion 8b. By being pressed against the inner surface of the fixed portion 14, the lock member 12 is positioned on the pedestal portion 8a of the case body 8. That is, when the fixing portion 14 is fixed to the pedestal portion 8 a by the plurality of screw members 16, the mounting state of the fixing portion 14 with respect to the pedestal portion 8 a, that is, the inclination of the fixing portion 14 in the vertical and horizontal directions is the elasticity of the waterproof member 18. Adjusted by

これにより、ロック部材12が台座部8aに対して位置決めされて、ケース本体8の貫通孔11とロック部材12の挿入孔12aとが同一軸上に対応して一致する。また、このときには、防水部材18が固定部14の凸部17の外周面と台座部8aの凹部8bの内周面との間に挟まれるので、この防水部材18によって固定部14の凸部17と台座部8aの凹部8bとの間の防水が図られる。 As a result, the lock member 12 is positioned with respect to the pedestal portion 8a, and the through hole 11 of the case body 8 and the insertion hole 12a of the lock member 12 are aligned and aligned on the same axis. Further, at this time, since the waterproof member 18 is sandwiched between the outer peripheral surface of the convex portion 17 of the fixed portion 14 and the inner peripheral surface of the concave portion 8b of the pedestal portion 8a, the waterproof member 18 causes the convex portion 17 of the fixed portion 14 to be covered. Waterproofing between the base and the concave portion 8b of the pedestal portion 8a is achieved.

この状態で、ケース本体8の上部開口部に時計ガラス5を取り付けて、ケース本体8の外周に第1外装部9aを取り付けた上、ケース本体8の上部外周および第1外装部9aの上部外周に第2外装部9bを取り付ける。このときには、ロック部材12のロック部15を除いて、ロック部材12の固定部14の両側部および複数のねじ部材16が外装部材9によって覆われる。 In this state, the watch glass 5 is attached to the upper opening of the case body 8, the first exterior portion 9a is attached to the outer periphery of the case body 8, and the outer periphery of the upper portion of the case body 8 and the outer periphery of the first outer portion 9a are attached. The second exterior portion 9b is attached to. At this time, both sides of the fixed portion 14 of the lock member 12 and the plurality of screw members 16 are covered by the exterior member 9 except for the lock portion 15 of the lock member 12.

そして、ロック部材12の挿入孔12aとケース本体8の貫通孔11とに操作部材13を挿入させる。このときには、予め、操作部材13を組み立てる。この場合には、頭部21のリング状の凹部21a内に緩衝材27を挿入させると共に、本体軸22内の非円形孔部22aおよび円形孔部22b内にコイルばね26を挿入させる。 Then, the operation member 13 is inserted into the insertion hole 12 a of the lock member 12 and the through hole 11 of the case body 8. At this time, the operation member 13 is assembled in advance. In this case, the cushioning material 27 is inserted into the ring-shaped recess 21a of the head 21, and the coil spring 26 is inserted into the non-circular hole 22a and the circular hole 22b in the main body shaft 22.

この状態で、操作軸24の一端部が取り付けられたスライド連結部23をコイルばね26のばね力に抗して本体軸22の非円形孔部22a内に挿入させて、本体軸22内の内端部に抜止め部22cを取り付ける。これにより、操作軸24がスライド連結部23を介して本体軸22に取り付けられて、操作部材13が組み立てられる。 In this state, the slide connecting portion 23 to which one end of the operation shaft 24 is attached is inserted into the non-circular hole portion 22a of the main body shaft 22 against the spring force of the coil spring 26, and the inside of the main body shaft 22 is inserted. The retaining portion 22c is attached to the end. As a result, the operation shaft 24 is attached to the main body shaft 22 via the slide connecting portion 23, and the operation member 13 is assembled.

そして、操作部材13をロック部材12の挿入孔12aとケース本体8の貫通孔11とに挿入させる際には、予め、ケース本体8内に時計モジュール7を組み込む。この状態で、操作部材13の操作軸24をロック部材12の挿入孔12aとケース本体8の貫通孔11とに挿入させて時計モジュール7内に差し込んで位置規制し、本体軸22をロック部材12の挿入孔12aに挿入させる。これにより、操作軸24が時計モジュール7内に位置規制されて、操作部材13が取り付けられるので、スイッチ装置4が組み立てられる。 Then, when the operation member 13 is inserted into the insertion hole 12 a of the lock member 12 and the through hole 11 of the case body 8, the timepiece module 7 is incorporated in the case body 8 in advance. In this state, the operation shaft 24 of the operation member 13 is inserted into the insertion hole 12a of the lock member 12 and the through hole 11 of the case main body 8 and inserted into the timepiece module 7 to regulate the position, and the main body shaft 22 is locked. Is inserted into the insertion hole 12a. As a result, the position of the operation shaft 24 is regulated in the timepiece module 7 and the operation member 13 is attached, so that the switch device 4 is assembled.

この場合、操作軸24は、本体軸22内にスライド可能に配置されたスライド連結部23の外径、つまりケース本体8の貫通孔11の小径孔11aの内径よりも外径が小さい棒状に形成されている。このため、ケース本体8の貫通孔11の小径孔11aは、その内径を操作軸24が挿入可能な最小限の大きさで小さく形成することが可能になり、ケース本体8の上下方向の長さ(厚み)を短く(薄く)形成することができる。 In this case, the operation shaft 24 is formed in a rod shape having an outer diameter smaller than the outer diameter of the slide coupling portion 23 slidably arranged in the body shaft 22, that is, the inner diameter of the small diameter hole 11a of the through hole 11 of the case body 8. Has been done. Therefore, the small-diameter hole 11a of the through hole 11 of the case body 8 can be formed to have a small inner diameter with a minimum size into which the operation shaft 24 can be inserted, and the length of the case body 8 in the vertical direction. (Thickness) can be made short (thin).

次に、このスイッチ装置4を操作する場合について説明する。
このスイッチ装置4を使用しない場合には、図4に示す通常状態で、操作部材13の頭部21をコイルばね26のばね力に抗してケース本体8の内部に向けて押し込んで、頭部21をロック部材12のロック部15にロックする。
Next, a case where the switch device 4 is operated will be described.
When this switch device 4 is not used, in the normal state shown in FIG. 21 is locked to the lock portion 15 of the lock member 12.

すなわち、図4に示す通常状態のときには、軸部20の操作軸24が時計モジュール7内に位置規制されている。この状態で、頭部21をケース本体8の内部に向けて押し込むと、コイルばね26のばね力に抗して本体軸22がロック部材12の挿入孔12a内においてケース本体8の内部側に向けてスライドする。 That is, in the normal state shown in FIG. 4, the position of the operation shaft 24 of the shaft portion 20 is regulated in the timepiece module 7. In this state, when the head portion 21 is pushed toward the inside of the case body 8, the body shaft 22 faces the inside of the case body 8 in the insertion hole 12a of the lock member 12 against the spring force of the coil spring 26. Slide.

このときには、時計モジュール7内で位置規制された操作軸24によって、スライド連結部23が本体軸22のスライドに伴って本体軸22の非円形孔部22a内に押し込まれ、スライド連結部23のストッパ部23aが本体軸22の抜止め部22cから離れる。この状態で、頭部21を一方向に回転させて、頭部21の雌ねじ部21bをロック部材12の雄ねじ部15aに螺合させて締め付ける。 At this time, the slide connecting portion 23 is pushed into the non-circular hole portion 22a of the main body shaft 22 by the operation shaft 24 whose position is regulated in the timepiece module 7, and the stopper of the slide connecting portion 23 is stopped. The portion 23a is separated from the retaining portion 22c of the main body shaft 22. In this state, the head portion 21 is rotated in one direction so that the female screw portion 21b of the head portion 21 is screwed into the male screw portion 15a of the lock member 12 and tightened.

すると、コイルばね26のばね力に抗して本体軸22がロック部材12の挿入孔12a内においてケース本体8の内部側に向けて徐々にスライドし、この本体軸22のスライドに伴ってスライド連結部23が本体軸22内の非円形孔部22a内に徐々に押し込まれて、ストッパ部23aが抜止め部22cから徐々に離れる。 Then, the body shaft 22 gradually slides toward the inside of the case body 8 in the insertion hole 12a of the lock member 12 against the spring force of the coil spring 26, and the body shaft 22 is slid and coupled as the body shaft 22 slides. The portion 23 is gradually pushed into the non-circular hole portion 22a in the main body shaft 22, and the stopper portion 23a is gradually separated from the retaining portion 22c.

このように頭部21が一方向に回転された際には、頭部21の回転に伴ってスライド連結部23のストッパ部23aが本体軸22と共に回転し、このスライド連結部23の回転と共に操作軸24が回転しながら、頭部21の雌ねじ部21bがロック部材12の雄ねじ部15aに螺合して、頭部21がロック部15にロックされる。このため、スイッチ装置4は不用意に動作することはない。 In this way, when the head 21 is rotated in one direction, the stopper portion 23a of the slide connecting portion 23 rotates together with the main body shaft 22 as the head 21 rotates, and the stopper 23a of the slide connecting portion 23 operates together with the rotation of the slide connecting portion 23. While the shaft 24 rotates, the female screw portion 21b of the head portion 21 is screwed into the male screw portion 15a of the lock member 12, and the head portion 21 is locked by the lock portion 15. Therefore, the switch device 4 does not operate carelessly.

また、このスイッチ装置4を操作する場合には、まず、操作部材13の頭部21を一方向と反対方向に回転させて、ロック部材12による操作部材13のロックを解除する。すなわち、頭部21を反対方向に回転させると、ロック部材12の雄ねじ部15aに対する頭部21の雌ねじ部21bの螺合が緩められて、ロック部15による頭部21のロックが解除される。 Further, when operating the switch device 4, first, the head 21 of the operating member 13 is rotated in the opposite direction to the one direction to unlock the operating member 13 by the lock member 12. That is, when the head portion 21 is rotated in the opposite direction, the screw engagement of the female screw portion 21b of the head portion 21 with the male screw portion 15a of the lock member 12 is loosened, and the lock of the head portion 21 by the lock portion 15 is released.

このときには、ロック部材12の雄ねじ部15aに対する頭部21の雌ねじ部21bの螺合が外れるので、コイルばね26のばね力によって本体軸22が頭部21と共にケース本体8の外部に向けて押し出されて、スライド連結部23が本体軸22の非円形孔部22a内から引き出され、ストッパ部23aが抜止め部22cに当接する。 At this time, the female screw portion 21b of the head portion 21 is unscrewed from the male screw portion 15a of the lock member 12, so that the main body shaft 22 is pushed out of the case main body 8 together with the head portion 21 by the spring force of the coil spring 26. Then, the slide connecting portion 23 is pulled out from the inside of the non-circular hole portion 22a of the main body shaft 22, and the stopper portion 23a abuts the retaining portion 22c.

この状態で、頭部21が更にケース本体8の外部に引き出されると、本体軸22がロック部材12の挿入孔12a内をスライドして頭部21と共に引き出される。このときには、スライド連結部23が抜止め部22cに当接しているので、スライド連結部23が本体軸22と共に引き出される。これに伴って操作軸24が引き出されるので、操作軸24が時計モジュール7内でスライドする。これにより、時計モジュール7が時刻修正可能な状態になる。 In this state, when the head portion 21 is further pulled out of the case body 8, the body shaft 22 slides in the insertion hole 12a of the lock member 12 and is pulled out together with the head portion 21. At this time, since the slide connecting portion 23 is in contact with the retaining portion 22c, the slide connecting portion 23 is pulled out together with the main body shaft 22. Along with this, the operation shaft 24 is pulled out, so that the operation shaft 24 slides in the timepiece module 7. As a result, the timepiece module 7 is ready for time adjustment.

この状態で、頭部21を回転させると、この頭部21の回転に伴って本体軸22がロック部材12の挿入孔12a内で回転し、この本体軸22の回転に伴ってスライド連結部23のストッパ部23aがスライド連結部23と共に回転する。すると、このスライド連結部23の回転に伴って操作軸24が時計モジュール7内で回転する。これにより、時計モジュール7の時刻修正が実行される。 When the head 21 is rotated in this state, the body shaft 22 rotates in the insertion hole 12a of the lock member 12 as the head 21 rotates, and the slide connecting portion 23 rotates as the body shaft 22 rotates. The stopper portion 23a rotates together with the slide connecting portion 23. Then, the operation shaft 24 rotates in the timepiece module 7 as the slide connecting portion 23 rotates. As a result, the time adjustment of the clock module 7 is executed.

このように、この腕時計のスイッチ装置4によれば、貫通孔11が設けられたケース本体8と、このケース本体8の外面に固定され、中心部に挿入孔12aが貫通孔11と同一軸上に対応して設けられたロック部材12と、ケース本体8の貫通孔11とロック部材12の挿入孔12aとにスライド可能に挿入されてロック部材12にロックされる操作部材13と、を備えていることにより、ロック部材12によって操作部材13をロックするロック機構を備えていても、ケース本体8の薄型化を図ることができる。 As described above, according to the switch device 4 of the wristwatch, the case main body 8 having the through hole 11 is fixed, and the insertion hole 12a is fixed to the outer surface of the case main body 8 and is coaxial with the through hole 11 at the center. A lock member 12 provided in correspondence with the lock member 12, and an operation member 13 slidably inserted into the through hole 11 of the case body 8 and the insertion hole 12a of the lock member 12 and locked by the lock member 12. Therefore, even if the lock mechanism that locks the operation member 13 with the lock member 12 is provided, the case body 8 can be made thin.

また、ロック部材12はケース本体8の外面に固定されるため、ケース本体の貫通孔にパイプを嵌め込みケース本体内で固定し、パイプに操作部材をロックする従来の構造よりも、ケース本体8の径方向への小型化を図ることができると共に、腕時計全体の径方向への小型化を図ることができる。 Further, since the lock member 12 is fixed to the outer surface of the case body 8, the case body 8 is provided with a structure more than that of the conventional structure in which the pipe is fitted into the through hole of the case body to be fixed in the case body and the operation member is locked to the pipe. The size of the wristwatch can be reduced in the radial direction, and the size of the entire wristwatch can be reduced in the radial direction.

すなわち、この腕時計のスイッチ装置4では、ケース本体8の貫通孔11を操作部材13が挿入可能な最小限の大きさで小さく形成することができるので、ロック部材12によって操作部材13をロックするロック機構を備えていても、ケース本体8の上下方向の厚みを薄く形成することができ、これによりケース本体8の薄型化を図ることができると共に、腕時計全体の薄型化を図ることができる。 That is, in the switch device 4 of this wristwatch, the through hole 11 of the case body 8 can be formed to be as small as the smallest size into which the operating member 13 can be inserted, so that the lock member 12 locks the operating member 13 to be locked. Even if the case body is provided, the thickness of the case body 8 in the up-down direction can be made thin, and thus the case body 8 can be made thin and the wristwatch as a whole can be made thin.

また、ケース本体8の貫通孔11を操作部材13が挿入可能な最小限の大きさで小さく形成することで、貫通孔11の周辺のケース本体の肉厚を十分確保することができ、ケース本体8の強度を上げることができる。また、貫通孔11の小径孔11aと大径孔11bの内径は同じであっても良い。 Further, by forming the through-hole 11 of the case body 8 to a minimum size in which the operation member 13 can be inserted, the wall thickness of the case body around the through-hole 11 can be sufficiently secured, and the case body can be secured. The strength of 8 can be increased. Further, the inner diameters of the small diameter hole 11a and the large diameter hole 11b of the through hole 11 may be the same.

この場合、このスイッチ装置4では、ロック部材12のロック部15の外周面に雄ねじ部15aが設けられ、操作部材13の頭部21に設けられた凹部21aの内周面に雌ねじ部21bが設けられていることにより、ロック機構を構成することができるので、操作部材13をケース本体8の内部側に向けて押し込んだ状態で、頭部21の雌ねじ部21bをロック部15の雄ねじ部15aに螺合させて締め付けることができ、これにより操作部材13をケース本体8に対して確実にかつ良好にロックすることができる。 In this case, in the switch device 4, the male screw portion 15a is provided on the outer peripheral surface of the lock portion 15 of the lock member 12, and the female screw portion 21b is provided on the inner peripheral surface of the recessed portion 21a provided in the head portion 21 of the operation member 13. Since the lock mechanism can be configured by being provided, the female screw portion 21b of the head portion 21 is connected to the male screw portion 15a of the lock portion 15 in a state where the operating member 13 is pushed toward the inner side of the case body 8. It can be screwed and tightened, and thereby the operation member 13 can be reliably and satisfactorily locked to the case body 8.

また、このスイッチ装置4は、ロック部材12が、ケース本体8の外面に固定される固定部14と、操作部材13をロック解除可能にロックするロック部15と、を備えていることにより、ロック部材12の挿入孔12aをケース本体8の貫通孔11と同一軸上に対応させた状態で、固定部14をケース本体8の外面に固定することができるので、ロック部材12が操作部材13をロックするロック部15を備えていても、ロック部材12を固定部14によってケース本体8の外面に確実にかつ良好に取り付けることができる。 Further, the switch device 4 is locked by the lock member 12 including the fixing portion 14 fixed to the outer surface of the case body 8 and the lock portion 15 that locks the operation member 13 so as to be unlocked. Since the fixing portion 14 can be fixed to the outer surface of the case body 8 in a state where the insertion hole 12a of the member 12 is aligned with the through hole 11 of the case body 8, the fixing portion 14 can be fixed to the outer surface of the case body 8. Even if the lock member 15 for locking is provided, the lock member 12 can be reliably and satisfactorily attached to the outer surface of the case body 8 by the fixing portion 14.

この場合、固定部14は、両側部にねじ挿入孔14aが設けられ、ケース本体8の外面に設けられた台座部8aに配置された際に、各ねじ挿入孔14aが台座部8aに設けられた各ねじ穴8cにそれぞれ対応し、この状態で複数のねじ部材16を各ねじ挿入孔14aを通して台座部8aの各ねじ穴8cに螺合させて締め付けることにより、ケース本体8の台座部8aに確実にかつ強固に固定させることができる。また、このロック部材12は、固定部14とロック部15とが一体に形成されているので、部品点数の削減を図り、組立作業の簡素化を図ることができる。 In this case, the fixing portion 14 is provided with screw insertion holes 14a on both sides, and when the fixing portion 14 is arranged on the pedestal portion 8a provided on the outer surface of the case body 8, each screw insertion hole 14a is provided on the pedestal portion 8a. Corresponding to the respective screw holes 8c, and in this state, a plurality of screw members 16 are screwed into the respective screw holes 8c of the pedestal portion 8a through the respective screw insertion holes 14a so as to be tightened, whereby the pedestal portion 8a of the case main body 8 is secured. It can be securely and firmly fixed. Further, since the lock member 12 has the fixed portion 14 and the lock portion 15 formed integrally with each other, the number of parts can be reduced and the assembling work can be simplified.

また、このスイッチ装置4では、操作部材13が、ケース本体8の貫通孔11とロック部材12の挿入孔12aとにスライド可能に挿入される軸部20と、この軸部20の外端部に設けられてロック部材12にロック解除可能にロックされる頭部21と、を備えていることにより、頭部21をスライド操作させて軸部20をケース本体8の貫通孔11およびロック部材12の挿入孔12a内で良好にスライドさせることができると共に、頭部21を回転操作させて軸部20をケース本体8の貫通孔11およびロック部材12の挿入孔12a内で良好に回転させることができる。 Further, in the switch device 4, the operating member 13 is provided on the shaft portion 20 slidably inserted into the through hole 11 of the case body 8 and the insertion hole 12a of the lock member 12, and the outer end portion of the shaft portion 20. By providing the head portion 21 that is provided and locked to the lock member 12 so as to be unlocked, the head portion 21 can be slid to move the shaft portion 20 into the through hole 11 of the case body 8 and the lock member 12. It can be slid well in the insertion hole 12a, and the shaft portion 20 can be satisfactorily rotated in the through hole 11 of the case body 8 and the insertion hole 12a of the lock member 12 by rotating the head portion 21. ..

この場合、操作部材13は、頭部21の外径が軸部20の外径よりも大きくても、ケース本体8の貫通孔11に挿入する軸部20の外径を頭部21の外径よりも大幅に小さくすることができるので、ケース本体8の貫通孔11の内径を軸部20が挿入可能な最小限の大きさで小さく形成することができ、これによりケース本体8の上下方向の厚みを薄く形成することができる。 In this case, in the operation member 13, even if the outer diameter of the head portion 21 is larger than the outer diameter of the shaft portion 20, the outer diameter of the shaft portion 20 to be inserted into the through hole 11 of the case body 8 is the outer diameter of the head portion 21. Since the inner diameter of the through hole 11 of the case body 8 can be made smaller than the minimum size in which the shaft portion 20 can be inserted, the vertical direction of the case body 8 can be reduced. The thickness can be reduced.

すなわち、このスイッチ装置4では、軸部20が、ロック部材12の挿入孔12aにスライド可能に挿入される本体軸22と、この本体軸22よりも小径で本体軸22にスライド連結部23を介して取り付けられてケース本体8の貫通孔11を通してケース本体8内にスライド可能に挿入される操作軸24と、を備えていることにより、操作部材13をケース本体8の内部側に向けて押し込んでロック部材12にロックさせる際に、スライド連結部23によって操作軸24がケース本体8内に不必要に押し込まれないようにすることができる。 That is, in the switch device 4, the shaft portion 20 has a main body shaft 22 slidably inserted into the insertion hole 12 a of the lock member 12, and a slide connecting portion 23 having a smaller diameter than the main body shaft 22 and connected to the main body shaft 22. And the operation shaft 24 slidably inserted into the case body 8 through the through hole 11 of the case body 8, the operation member 13 is pushed toward the inside of the case body 8. When the lock member 12 is locked, the operation shaft 24 can be prevented from being unnecessarily pushed into the case body 8 by the slide connecting portion 23.

この場合、軸部20は、本体軸22がロック部材12の挿入孔12aにスライド可能に挿入されて、ケース本体8の貫通孔11内に挿入されることがなく、操作軸24がケース本体8の貫通孔11内にスライド可能に挿入され、この操作軸24の外径が本体軸22の外径よりも小さく形成されているので、本体軸22の外径が操作軸24の外径よりも大きくても、ケース本体8の貫通孔11の内径を小径の操作軸24が挿入可能な最小限の大きさで小さく形成することができ、これによりケース本体8の上下方向の厚みを確実に薄く形成することができる。 In this case, in the shaft portion 20, the main body shaft 22 is not slidably inserted into the insertion hole 12 a of the lock member 12 and is not inserted into the through hole 11 of the case body 8, and the operation shaft 24 is the case body 8. The outer diameter of the operation shaft 24 is smaller than the outer diameter of the main body shaft 22, so that the outer diameter of the main body shaft 22 is smaller than the outer diameter of the operation shaft 24. Even if it is large, the inner diameter of the through hole 11 of the case body 8 can be formed to be as small as the smallest size into which the small-diameter operation shaft 24 can be inserted, and thus the thickness of the case body 8 in the vertical direction can be surely thin. Can be formed.

さらに、このスイッチ装置4では、ケース本体8の外面に設けられた台座部8aの凹部8bの内周面とロック部材12の固定部14の内端面に設けられて台座部8aの凹部8b内に挿入される凸部17の外周面との間に配置される防水部材18を備えていることにより、防水部材18によって固定部14の凸部17と台座部8aの凹部8bとの間の防水を図ることができる。 Further, in the switch device 4, the inner peripheral surface of the recess 8b of the pedestal portion 8a provided on the outer surface of the case body 8 and the inner end surface of the fixing portion 14 of the lock member 12 are provided in the recess 8b of the pedestal portion 8a. Since the waterproof member 18 is provided between the convex portion 17 to be inserted and the outer peripheral surface of the convex portion 17, the waterproof member 18 serves to waterproof the convex portion 17 of the fixed portion 14 and the concave portion 8b of the pedestal portion 8a. Can be planned.

また、このスイッチ装置4では、防水部材18がケース本体8の外面の台座部8aに対してロック部材12を位置決めすることにより、固定部14を複数のねじ部材16によって台座部8aに固定する際に、台座部8aに対する固定部14の取付状態、つまり固定部14の上下左右方向の傾きを防水部材18の弾力によって調整することができる。これにより、ロック部材12を台座部8aに対して正確に且つ良好に位置決めすることができるので、ケース本体8の貫通孔11とロック部材12の挿入孔12aとを同一軸上に対応させて一致させることができる。 In addition, in the switch device 4, when the waterproof member 18 positions the lock member 12 with respect to the pedestal portion 8a on the outer surface of the case body 8, when the fixing portion 14 is fixed to the pedestal portion 8a by the plurality of screw members 16. In addition, the mounting state of the fixing portion 14 with respect to the pedestal portion 8a, that is, the inclination of the fixing portion 14 in the vertical and horizontal directions can be adjusted by the elasticity of the waterproof member 18. As a result, the lock member 12 can be accurately and favorably positioned with respect to the pedestal portion 8a, so that the through hole 11 of the case body 8 and the insertion hole 12a of the lock member 12 are aligned and aligned on the same axis. Can be made.

(第2実施形態)
次に、図5〜図8を参照して、この発明を適用した腕時計の第2実施形態について説明する。なお、図1〜図4に示された第1実施形態と同一部分には同一符号を付して説明する。
この腕時計は、図5〜図8に示すように、ロック部材12のロック部30が第1実施形態と異なる構造であり、これ以外は第1実施形態とほぼ同じ構造になっている。
(Second embodiment)
Next, a second embodiment of a wrist watch to which the invention is applied will be described with reference to FIGS. The same parts as those of the first embodiment shown in FIGS. 1 to 4 will be described with the same reference numerals.
As shown in FIGS. 5 to 8, this wristwatch has a structure in which the lock portion 30 of the lock member 12 is different from that in the first embodiment, and is otherwise the same in structure as the first embodiment.

すなわち、ロック部30は、図5〜図7に示すように、固定部14の外面に設けられた円筒部であり、外周面に係止部31が固定部14の外面から離れた状態で設けられた構造になっている。この係止部31は、操作部材13の頭部21を係脱可能に係止するものであり、凸部31aと凹部31bとが円周方向に沿って交互に設けられた構造になっている。 That is, as shown in FIGS. 5 to 7, the lock portion 30 is a cylindrical portion provided on the outer surface of the fixed portion 14, and the locking portion 31 is provided on the outer peripheral surface in a state of being separated from the outer surface of the fixed portion 14. It has a special structure. The locking portion 31 locks the head portion 21 of the operation member 13 in a disengageable manner, and has a structure in which convex portions 31a and concave portions 31b are alternately provided along the circumferential direction. ..

一方、操作部材13の頭部21には、図5、図6、図8に示すように、ロック部30の係止部31に係脱可能に係止される係合部32が設けられている。この係合部32は、頭部21の凹部21a内におけるロック部材12側の内周面の端部に設けられている。すなわち、この係合部32は、ロック部30の係止部31と同様、凸部32aと凹部32bとが円周方向に沿って交互に設けられた構造になっている。これらロック部30の係止部31と頭部21内の係合部32とによって、ロック機構が構成されている。 On the other hand, as shown in FIGS. 5, 6, and 8, the head portion 21 of the operation member 13 is provided with an engaging portion 32 that is detachably engaged with the engaging portion 31 of the lock portion 30. There is. The engagement portion 32 is provided at an end portion of the inner peripheral surface on the lock member 12 side in the recess 21 a of the head portion 21. That is, the engaging portion 32 has a structure in which the convex portions 32a and the concave portions 32b are alternately provided along the circumferential direction, like the engaging portion 31 of the lock portion 30. The locking portion 31 of the lock portion 30 and the engaging portion 32 in the head portion 21 constitute a lock mechanism.

これにより、ロック部30は、図5〜図8に示すように、操作部材13の頭部21がコイルばね26のばね力に抗してケース本体8の内部側に向けて押し込まれて、ロック部30の係止部31に頭部21の係合部32が対面した際に、頭部21を回転させて、係止部31の凹部31bと係合部32の凸部32aとを対応させると、係合部32の凸部32aが係止部31の凹部31bを通り抜けるように構成されている。 Thereby, as shown in FIGS. 5 to 8, the lock portion 30 is locked by the head portion 21 of the operation member 13 being pushed toward the inside of the case body 8 against the spring force of the coil spring 26. When the engaging portion 32 of the head portion 21 faces the engaging portion 31 of the portion 30, the head portion 21 is rotated so that the concave portion 31b of the engaging portion 31 and the convex portion 32a of the engaging portion 32 correspond to each other. And the convex portion 32a of the engaging portion 32 passes through the concave portion 31b of the locking portion 31.

また、このロック部30は、図5〜図8に示すように、頭部21の係合部32がロック部30の係止部31を通り抜けた状態で、頭部21を回転させて、係止部31の凸部31aと係合部32の凸部32aとを対応させて重ね合せた際に、コイルばね26のばね力で係止部31の凸部31aの内面に、これに対面する係合部32の凸部32aの対向面が押し当てられることにより、頭部21をロックするように構成されている。 Further, as shown in FIGS. 5 to 8, the lock portion 30 is rotated by rotating the head portion 21 with the engagement portion 32 of the head portion 21 passing through the locking portion 31 of the lock portion 30. When the convex portion 31a of the stopper portion 31 and the convex portion 32a of the engaging portion 32 are superposed in correspondence with each other, the spring force of the coil spring 26 faces the inner surface of the convex portion 31a of the locking portion 31. The head 21 is configured to be locked by pressing the facing surface of the convex portion 32a of the engaging portion 32.

また、このロック部30は、図5〜図8に示すように、頭部21をロックした状態で、頭部21を回転させて係止部31の凹部31bと係合部32の凸部32aとを対応させると、頭部21のロックが解除されるように構成されている。すなわち、このロック部30は、頭部21のロックが解除された際に、コイルばね26のばね力によって頭部21がケース本体8の外部に向けて押し出されて、係合部32の凸部32aが係止部31の凹部31bを通り抜けて、頭部21がケース本体8の外部に押し出されるように構成されている。 Further, as shown in FIGS. 5 to 8, the lock portion 30 rotates the head portion 21 in a state where the head portion 21 is locked to rotate the head portion 21 and the concave portion 31b of the locking portion 31 and the convex portion 32a of the engaging portion 32. It is configured such that the lock of the head portion 21 is released by making the two correspond to. That is, in the lock portion 30, when the lock of the head portion 21 is released, the head portion 21 is pushed out toward the outside of the case body 8 by the spring force of the coil spring 26, and the convex portion of the engaging portion 32. 32a passes through the recess 31b of the locking portion 31, and the head portion 21 is pushed out of the case body 8.

このような腕時計のスイッチ装置4によれば、第1実施形態と同様の作用効果があるほか、ロック部材12のロック部30に係止部31が設けられ、頭部21の凹部21a内に係合部32が設けられていることにより、頭部21を押し込んだ状態で所定角度回転させるだけで、簡単にかつ確実に頭部21をロックすることができる。 According to the switch device 4 of such a wristwatch, in addition to the same effect as the first embodiment, the locking portion 31 of the lock member 12 is provided with the locking portion 31, and the locking portion 31 is provided in the recess 21a of the head portion 21. Since the joint portion 32 is provided, the head portion 21 can be locked easily and reliably only by rotating the head portion 21 by a predetermined angle in a pushed state.

すなわち、このスイッチ装置4では、操作部材13の頭部21をケース本体8の内部側に向けて押し込んで、頭部21を所定角度回転させて、係止部31の凹部31bと係合部32の凸部32aとを対応させると、係合部32の凹部32bが係止部31の凹部31bを通り抜け、この状態で頭部21を回転させて、係止部31の凸部31aと係合部32の凸部32aとを対応させて重ね合わせることにより、簡単に頭部21をロックすることができる。 That is, in the switch device 4, the head 21 of the operation member 13 is pushed toward the inside of the case body 8 to rotate the head 21 by a predetermined angle, and the recess 31b of the locking portion 31 and the engaging portion 32 are rotated. When the concave portion 32b of the engaging portion 32 is passed through the concave portion 31b of the locking portion 31, the head portion 21 is rotated in this state to engage with the convex portion 31a of the locking portion 31. The head 21 can be easily locked by superimposing the convex portions 32a of the portion 32 in correspondence with each other.

また、このスイッチ装置4では、頭部21をロックした状態で、頭部21を回転させて係止部31の凹部31bと係合部32の凸部32aとを対応させると、係合部32の凸部32aが係止部31の凹部31bを通り抜けるので、簡単に頭部21のロックを解除することができ、これによりロック部30によるロック操作の簡素化を図ることができる。 Further, in the switch device 4, when the head 21 is rotated and the concave portion 31b of the locking portion 31 and the convex portion 32a of the engaging portion 32 are made to correspond to each other, the engaging portion 32 is locked. Since the convex portion 32a of the above passes through the concave portion 31b of the locking portion 31, the lock of the head portion 21 can be easily released, whereby the locking operation by the lock portion 30 can be simplified.
