Abstract
A controller of a valve timing control apparatus executes an initial control and a normal control. The normal control causes a rotation phase of a vane rotor to be changed by controlling working fluid to flow into or out of operation chambers. The initial control causes working fluid to intermittently flow into a predetermined operation chamber of the operation chambers. The controller starts the initial control when an engine is activated. The controller switches the initial control into the normal control after the initial control is finished.
