Abstract
A valve timing control device has a case rotating in synchronization with a crankshaft of an engine. A plurality of projections, which project outwardly in a radial direction of the case, are arranged on an outer circumferential portion of the case at regular intervals. The projection is a chuck site allowing the engagement of a chuck tool of an automatic machine used for an auto-assembly work, the chuck tool being operated in the radial direction. A tapered face is formed at a side, close to the chuck tool, of the projection, the tapered face easily allowing the engagement of the chuck tool when the chuck tool proceeds toward the device.
