Abstract
A valve timing control device includes a driving side rotational member, a driven side rotational member, a fluid pressure chamber, a parting portion dividing the fluid pressure chamber into an advanced angle chamber and a retarded angle chamber, a restriction member, a restriction recessed portion for restricting a displacement of a relative rotational phase within a range between a most advanced angle phase or a most retarded angle phase and a predetermined phase when the restriction member is inserted into the restriction recessed portion, and a restriction cancellation passage, wherein a communication between the accommodation portion and one of the advanced angle chamber and the retarded angle chamber via the cancellation passage is interrupted at least when the restriction member contacts one of end portions of the restriction recessed portion, and the restriction member is restricted so as not to move over the other one of the end portions.
