Abstract
A drivig rotary shaft and a follower rotary shaft are rotatably carried in a housing of a rotary solenoid. Operating members fixed to the rotary shafts by clips are operatively connected to each other by gears, and a locked member is locked non-movably by locking surfaces formed at tip ends of the operating members. This makes it unnecessary to provide a device for converting a rectilinear motion to a rotational motion such as a pin and an elongated bore in a path of transmission of a driving force from the rotary solenoid to the operating members. Therefore, not only the number of parts and the number of assembling steps are reduced, but also the number of slide areas, where a friction resistance and looseness are liable to be produced, is reduced, thereby enabling a noiseless smooth operation.
