Reclining apparatus for vehicle seat

A reclining apparatus for a vehicle seat, comprising:

• a lower plate provided at each side of either one of a seat cushion and a seat back;
• an upper plate provided at each side of the other of the seat cushion and the seat back and rotatably supported by each lower plate;
• a cam operatively connected to each lower and upper plate for restricting or permitting rotation of each upper plate relative to each lower plate as each cam rotates;
• a connecting shaft fitted to each cam with a fit clearance for rotating each cam in order to permit the rotation of each upper plate relative to each lower plate according to operational force inputted to the connecting shaft, the connecting shaft including an outer surface presenting a profile;
• and
• a spring biasing each cam in a first rotational direction in which the rotation of each upper plate relative to each lower plate is restricted, the spring including a pressing portion which contacts the connecting shaft pressing the connecting shaft in the first rotational direction to eliminate a play corresponding to the fit clearance between each cam and the connecting shaft;
• wherein each spring possesses first and second ends, and both first and second ends terminate at a position outside of the profile of the connecting shaft.
