A valve timing control device (10) has a first pressure chamber (54,56,58,60,62) and a second pressure chamber (64,66,68,70,72) to rotate the vanes (52) and a fluid supplying means (112) for supplying fluid under pressure selectively to the first or the second pressure chambers in order to control the valve timing. The device further includes a locking means (42,98,44) for connecting together a housing member (18) and a rotor (22) and a cancelling means (96) for cancelling the locking means. The cancelling means (96) cancels the locking means (42,98,44) before the fluid supplying means (112) supplies fluid under pressure to the first pressure chamber or the second pressure chamber so that the locking means (42,98,44) is cancelled completely before the vanes (52) rotate to advance or retard the timing. <IMAGE> |
