Abstract
The valve timing adjusting apparatus comprises a bias means that generates an urging force between the casing and the rotor, and the thus generated urging force is set to the level equal to or below the average inertia torque of the camshaft within the time period until the spark ignition is generated after one rotation of the crank shaft at the starting time of the combustion engine, so that by the varied torque at the time of starting of the combustion engine and the urging force, the rotor can be rapidly shifted toward the advance side or retard side with a relatively small force, improving thereby the response characteristic of the valve opening/closing system.
