Claims

[Claims for Utility Model Registration] A shaft portion having a fitting portion with a tapered surface formed on the outer periphery, and a plurality of shaft portions each having a tapered portion corresponding to the tapered surface of the shaft portion and applying a spring force toward the center. It has a gear part having a spring member, and a receiving part formed on either the shaft part or the gear part, and the fitting part of the shaft part is pushed between the plurality of spring members of the gear part. When holding elastically, the spring force of the spring member is distributed in the axial direction and the center direction due to the correspondence between the tapered surface of the shaft portion and the tapered portion of the spring member, and the spring force distributed in the axial direction is used. bringing the fitting part or the spring member into contact with the receiving part;
A slip gear mechanism for a timepiece, characterized in that the shaft part and the gear part are attached to be capable of slip rotation by elastically holding the fitting part with a spring force distributed in a central direction.
