Patent ID: 8165785

Claim:
A variable valve timing apparatus changing an opening/closing timing of at least any one of an intake valve and an exhaust valve, comprising: an actuator operating said variable valve timing apparatus; a change mechanism changing said opening/closing timing at a first variation amount with respect to an operation amount of said actuator in a case where said opening/closing timing is in a first region, and changing said opening/closing timing at a second variation amount larger than said first variation amount with respect to an operation amount of said actuator in a case where said opening/closing timing is in a second region different from said first region; and an operation unit, wherein said operation unit controls said opening/closing timing by controlling power supply to said actuator, and controls said opening/closing timing such that said opening/closing timing is maintained by stopping power supply to said actuator, in a case where said opening/closing timing is in said first region.
