る内燃機関のバルブタイミング制御装置。 A cylindrical gear is meshed between a rotating body driven by an engine and a camshaft, and the cylindrical gear is moved in the axial direction of the camshaft using two hydraulic circuits, thereby creating a connection between the rotating body and the camshaft. In a valve timing control device that controls the opening and closing timing of intake and exhaust valves by obtaining relative rotation, a part of the first hydraulic circuit is inserted into an internal shaft of a fixing bolt that is screwed into a bolt hole in one end of the camshaft. A part of the second hydraulic circuit is formed between the bolt hole and the fixing bolt, and each hydraulic circuit is connected to the engine upstream of the first and second hydraulic circuits. A valve timing control device for an internal combustion engine, characterized in that it is provided with one directional control valve that is switched according to operating conditions.
