A valve timing control apparatus includes a driving rotary member driven by an engine, and a driven rotary member to drive a camshaft of the engine. The driven member is rotatable relative to the driving rotary member. A first movable member is provided in one of the rotary members, and arranged to move forwards and backwards. A second movable member is provided in the other of the rotary members, and arranged to move forwards and backwards. The first and second movable members are arranged to limit a relative rotation between the driving rotary member and the driven rotary member when both the first movable member and the second movable member are moved forwards, and to allow the relative rotation when at least one of the first and second movable members is moved backwards.
