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, the hydraulic passage of the first hydraulic circuit is connected to an internal shaft of a fixing bolt that is inserted and screwed into a bolt hole in one end of the camshaft. The second
A valve timing control device for an internal combustion engine, characterized in that a hydraulic passage of a hydraulic circuit is formed between the bolt hole and the fixing bolt.
