質のものとして扱わざるを得なかつた。 However, in the prior art described above, when the member 2 rotates, the watch case 1, the member 2, the fixing pin 3, and the fixing pipe 4 rub against each other, and due to strength issues, the material is made of stainless steel. In addition to fixing pin 3 and fixing pipe 4,
From the point of view of improving wear resistance, watch case 1,
It was also necessary for the member 2 to be made of a material with good wear resistance, such as stainless steel, or to have a surface treated with good wear resistance. However, in this case, processing becomes difficult in terms of material and processing, and there are restrictions on shape, etc., which poses a big problem, especially for members with dark decorative colors. Furthermore, if a material with poor wear resistance, such as brass, has to be used, it has to be treated as a low-quality material.

的効果は極めて大きなものである。 As described above, according to the present invention, direct contact between the member and the fixing pin can be avoided by mounting the engagement bushing with excellent wear resistance on the member, and By placing the tip of the engagement button protruding from the end face, it is possible to avoid direct contact between the end face of the member and the end face of the watch case, and the member can be made of easily machined material with poor wear resistance such as brass. , a movable structure with excellent wear resistance is obtained. In addition, even if the dimensional accuracy of the inner end surface of the member is poor or the surface treatment with rough processing thickness accuracy is applied to the member, it is possible to control and adjust the positional accuracy of the engaging bushing that is fixed to the member. It is possible to suppress rattling between the case and the member in the axial direction of the fixing pin. As described above, the practical effects of the present invention are extremely large.
