ABSTRACT:
A valve timing control device includes a rotor fixed on a cam shaft and having a circular groove opposite an end surface of the cam shaft. The circular groove communicates with a passage formed in the cam shaft. A housing member is disposed so as to surround the rotor. An angular phase converting mechanism is disposed between the rotor and the housing member so as to be able to transmit the rotational torque from the housing member to the rotor and so as to be able to give the angular phase difference between the rotor and the housing member. A fluid supplying device supplies fluid under pressure to the angular phase converting mechanism through the passage and the circular groove.
