Abstract
A variable valve timing control apparatus includes a driving side rotation member, a driven side rotation member positioned coaxially with a rotational axis of the driving side rotation member, at least one plate, a plurality of partition portions forming a fluid chamber between the partition portions, a vane portion being fitted to the fluid chamber to relatively rotate the driving side rotation member and the driven side rotation member within a movable range thereof, a restriction mechanism for restricting a relative rotational phase, a fastening member fixing the plate and the partition portion of the driving side rotation member, and a reinforcement member engaged with the partition portion including a contact surface among the partition portions, the contact surface being configured to receive a contact of the vane portion when the relative rotational phase is either at a most retarded angle phase or a most advanced angle phase.
