Patent ID: 7743743

Claim:
A variable valve timing apparatus changing an opening/closing timing of at least any one of an intake valve and an exhaust valve provided to an engine, comprising: an actuator; a change mechanism changing said opening/closing timing by changing difference in rotational phase of a camshaft driving the valve having said opening/closing timing changed, from a rotational phase of a crankshaft, at an amount of change according to an operation amount of said actuator; and an actuator operation amount setting portion setting the operation amount of said actuator, based on a deviation between said opening/closing timing at present of the valve having said opening/closing timing changed and a target value thereof, said actuator operation amount setting portion including actuator limiting means for setting the operation amount of said actuator to be smaller than at a time of engine operation, in a case where said opening/closing timing is changed at a time of engine stop.
