VALVE TIMING CONTROL DEVICE

摘要

A valve timing control device, comprising a locking mechanism controlling the relative rotation of an external rotor (5) and an internal rotor (7), the locking mechanism further comprising a plunger (45) which is allowed to move along the radial direction of the external rotor (5) and releasably restrains the relative rotation of the external rotor (5) and the internal rotor (7), a receiving hole (7a) which is provided around the outer periphery of the external rotor (7) and accepts the plunger (45), a spring (21) which presses the plunger (45) in the inner radial direction of the external rotor (5), a holder (46) which positions the spring (21), and a knock pin (47) which controls the movement of the holder (46) in the outer radial direction of the external rotor (5).
