A valve timing control device comprising a rotor adapted to be fixed on a cam shaft of an engine, a rotational transmitting member mounted around the peripheral surface of the rotor so as to rotate relative thereto within a predetermined range for transmitting a rotational power from a crank shaft, a chamber defined between the rotor and the rotational transmitting member and having first and second circumferentially opposed walls, a vane provided with the rotor and extended outwardly therefrom in the radial direction into the chamber so as to divide the chamber into an advancing chamber and a delaying chamber, the vane being movable between the first and second walls, a locking means for locking between the rotor and the rotational transmitting member at a predetermined relative phase, when the vane is not in contact with either the first or second walls, a first fluid passage for feeding and discharging a fluid to and from the advancing chamber, a second fluid passage for feeding and discharging the fluid to and from the delaying chamber, and a regulating means for making the predetermined relative phase between the rotor and the rotational transmitting member.
