Abstract
A restraining hole for restraining a stopper piston is constituted by a straight hole having an axis perpendicular to the direction of a relative rotation of a vane rotor with respect to a shoe housing and a tapered hole formed on a deep side of the straight hole and reduced in diameter on a deep side thereof. According to this construction, by virtue of a wedge effect between the tapered hole and the stopper piston, a relative rotation between a driving shaft system and a driven shaft system can be restrained at a predetermined angular position and it is possible to suppress the occurrence of a striking sound.
