Claim:
1. A reclining device for a vehicle seat comprising: a cam disposed between a mobile flange and a gear plate; a bearing having a coated surface adjoining the cam; a bush disposed between the gear plate and the bearing, wherein the bush absorbs part of welding heat generated during welding of the gear plate to the vehicle seat, thereby reducing an amount of the welding heat transferred to the bearing; an input device extending through the gear plate and covering the cam and the bearing; and a cap, an outer portion of the cap being coupled to the gear plate by welding, and an inner portion of the cap adjoining the input device, wherein the cap maintains a space between the input device and the gear plate in a hermetically closed state and increases the strength of the gear plate; and wherein the bush comprises a round cylindrical part and a base disposed protruding radially outward from the round cylindrical part and extending between the mobile flange and the gear plate, wherein an outer circumference of the cylindrical part of the bush engages a plate protrusion of the gear plate, and an inner circumference of the cylindrical part of the bush contacts an outer circumference of the bearing.
