SWITCH DEVICE AND TIMEPIECE

Abstract

A timepiece comprising a base member (12) provided with a stem insertion hole (14); an operation member (15) which has an engaging groove (20) provided in an outer circumferential surface thereof, and is slidably and rotatably inserted into the stem insertion hole (14) of the base member (12);a stopper member (21) having an engaging portion (22) which is arranged in the engaging groove (20) of the operation member (15) and moved along with sliding of the operation member (15);a release member (24) which releases the engaging portion (22) from the engaging groove (20); and a dial plate (13) which is arranged on one surface side of the base member (12). The release member (24) includes a pressing portion (30, 31) which is operated from the one surface side of the base member (12) so as to release the engaging portion (22) from the engaging groove (20). The pressing portion (30, 31) is a release lever (31) provided on the one surface of the base member (12), and is arranged to be exposed on the one surface side of the base member (12). The release lever (31) is a plate spring that is flexurally deformed toward the stopper member (21) upon a pressing operation to release the engaging portion (22) from the engaging groove (20), and includes a pressing operation portion (34) which is subjected to the pressing operation performed from the one surface side of the base member (12), and a release portion (35) which releases the engaging portion (22) from the engaging groove (20) by pressing a projection of the engaging portion (22) in response to the pressing operation performed on the pressing operation portion (34). An opening section for exposing at least a portion of the pressing portion on the one surface side is formed in the dial plate (13).
