そして、この操作軸部材15の軸部20を腕時計ケース1内の時計モジュール6に設けられた巻真27に装着させて取り付ける。これにより、操作部材13が腕時計ケース1に組み付けられて、スイッチ装置10が組み立てられる。   Then, the shaft portion 20 of the operation shaft member 15 is attached and attached to the winding stem 27 provided in the timepiece module 6 in the watch case 1. As a result, the operation member 13 is assembled to the wristwatch case 1 and the switch device 10 is assembled.

次に、このような腕時計におけるスイッチ装置10の作用について説明する。
このスイッチ装置10は、通常の状態のときに、操作部材13が第1ケース2の内部に向けて押し込まれて、図2に示す第1の位置に配置されている。このときには、操作部材13の操作軸部材15に取り付けられた巻真27が時計モジュール6の時計ムーブメント(図示せず)内に押し込まれている。この状態では、操作部材13の回転操作に応じて巻真27が回転しても、時計ムーブメントが動作しないニュートラル状態になっている。
Next, the operation of the switch device 10 in such a wristwatch will be described.
When the switch device 10 is in a normal state, the operation member 13 is pushed toward the inside of the first case 2 and is disposed at the first position shown in FIG. At this time, the winding stem 27 attached to the operation shaft member 15 of the operation member 13 is pushed into a timepiece movement (not shown) of the timepiece module 6. In this state, even if the winding stem 27 rotates according to the rotation operation of the operation member 13, the timepiece movement is in a neutral state.

この状態で、操作部材13を操作して時刻修正をする際には、まず、操作部材13を第1ケース2の外部に向けて引き出して第2の位置に配置する。このときには、操作部材13の装飾部材16を第1ケース2の外部に向けて引き出す。すると、操作部材13の軸部20が筒状部材12内をスライドして第1ケース2の外部に向けて引き出されると共に、装飾部材16が筒状部材12の大径筒部12bの外周に沿ってスライドして第1ケース2の外部に向けて引き出される。   In this state, when the operation member 13 is operated to correct the time, first, the operation member 13 is pulled out toward the outside of the first case 2 and arranged at the second position.
