A valve timing control apparatus includes a driving side rotational member (2) synchronously rotated with a crankshaft, a driven side rotational member (1) provided coaxially with the driving side rotational member and synchronously rotated with a camshaft (3), a fluid pressure chamber (40) being separated into an advanced angle chamber (43) and a retarded angle chamber (42), a phase control apparatus (9, 71, 76)-controlling an operation fluid to be supplied to and discharged from one of, or both of the advanced angle chamber and the retarded angle chamber, for displacing a relative rotational phase between the driving side rotational member and the driven side rotational member within a range from a most advanced angle phase to a most retarded angle phase, a locking mechanism (6) restraining the relative rotational phase at a lock phase between the most advanced angle phase and the most retarded angle phase. |
