Abstract

A reclining device has leg portions formed in opposed end portions of each of slide pawls. Basically, a rotating cam bears the slide pawl at a middle bearing portion formed in a middle portion between the leg portions. Furthermore, the rotating cam bears the slide pawl also at the leg portions. Such a three-point supporting structure prevents the middle portion of a slide pawl body from deflecting radially inwardly even in the event of application of a turning force from an annular ratchet. Thus, the slide pawls are stably maintained in mesh with the ratchet.
