Patent attributes
A reclining apparatus for a vehicle seat includes a lower plate, an upper plate rotatably supported by each lower plate, a cam for restricting or permitting rotation of each upper plate relative to each lower plate, a connecting shaft fitted to each cam with a fit clearance for integrally rotating each cam and a spring wound around a rotational axis of each cam for biasing each cam in a rotational direction in which rotation of each upper plate relative to each lower plate is restricted. A first end of each spring is engaged with each lower plate and a second end of each spring is engaged with each cam. The spring includes a pressing portion for pressing the connecting shaft so that a play corresponding to the fit clearance between each cam and the connecting shaft can be eliminated.
