SWITCH DEVICE AND TIMEPIECE INCLUDING SWITCH DEVICE

摘要

A switch device of the present invention includes a cylindrical member fitted into a through hole of a wristwatch case, an operating member having an operation shaft section to be inserted into the cylindrical member and an operation head section, and a lock member fixed inside the operation head section. The cylindrical member includes engaging projections, and the lock member includes resilient support sections which have a space with respect to the inner circumferential surface of the operation head section and are resiliently deformed in a radial direction, and lock sections with which the engaging projections are resiliently engaged. Accordingly, when the operating member is pushed inward and rotated, the engaging projections resiliently deform the resilient support sections and are engaged with the lock sections. Also, only by the operating member being rotated against the regulating force of the lock section, the lock sections are disengaged from the engaging projections.

主权项

1. A switch device comprising:
a case having a through hole; a cylindrical member fitted into the through hole of the case; an operating member having a shaft section to be inserted into the cylindrical member and an operating section on an outer end; and a lock member which is fixed inside the operating section of the operating member and slides and rotates together with the operating section along outer circumference of the cylindrical member, wherein the cylindrical member is provided with an engaging projection projecting toward inner circumferential surface of the lock member, and wherein the lock member includes an resilient support section which has a space with respect to inner circumferential surface of the operating section and are resiliently deformed in a radial direction, and a lock section which is provided to the resilient support section and with which the engaging projection is resiliently engaged when the operating section is pushed inward and rotated.
