By detachably attaching 12 to each other, it is possible to reliably prevent the rod-like member 11 inserted into the pair of insertion portions 9 from being accidentally pulled out from the pair of insertion portions 9.

  That is, even if the rod-shaped member 11 is configured to be easily taken out from the pair of insertion portions 9 when the watch case 1 is tilted and shaken, the cap portions 12 are respectively attached to the end portions 9a of the pair of insertion portions 9. Thus, it is possible to prevent the pair of insertion portions 9 from being inadvertently pulled out.

  In this case, since the cap part 12 is provided with the fitting part 12a fitted in the end part 9a of the insertion part 9, and the head part 12b provided in the edge part of this fitting part 12a, it is fitted. Simply by inserting the portions 12a into the end portions 9a of the pair of insertion portions 9 and pressing the head portions 12b against the end portions 9a of the insertion portions 9, the end portions 9a of the pair of insertion portions 9 can be easily and easily Can be attached. Thereby, since each head 12b can be made to contact the outer surface of the elastic projection part 8, the edge part 9a of each insertion part 9 can be covered by each head 12b, respectively.

  Moreover, since this cap part 12 is provided with the notch groove 12c in the head part 12b, it can form a clearance gap between the head part 12b and the outer surface of the elastic projection part 8 by this notch groove 12c. Since the fitting portion 12a can be pulled out from the pair of insertion portions 9 by hooking a fingernail into the gap, the cap portion 12 can be easily and easily removed from the end portions 9a of the pair of insertion portions 9. Can do.
