Abstract
A variable valve timing system that inhibits or substantially prevents the generation of noise produced by the vane at engine start, improves smooth engine start and enlarges the variable timing control area includes a first relative rotation restricting member restricting relative rotation between a rotation member and a rotation transmitting member from the most advanced angle position to the most retarded angle position at a position corresponding to engine start and a second rotation restricting member restricting relative rotation between the rotation member and the rotation transmitting member from the most retarded angle position to the most advanced angle position at the position corresponding to the engine start and releasing the restriction by fluid pressure in the advanced angle chamber.
