Abstract
In an auto cancel mechanism for a turn signal switch device, a click stop mechanism includes a click feeling-generating body formed from an elastic material and supported on a switch case, and a click pin supported on a switch actuator and resiliently pressed against the click feeling-generating body. Since the click feeling-generating body is formed integrally with an elastic stopper part disposed between a guide pin and a front end of a guide groove, the guide pin collides with the elastic stopper part without colliding with the front end of the guide groove, and noise generated by the collision is reduced. Moreover, since the elastic stopper part is formed integrally by utilizing the click feeling-generating body, it is possible to suppress an increase in the number of components and the number of assembly steps.
