Abstract
A valve timing control apparatus includes a rotor linked to a camshaft of an internal combustion engine. A drive member is linked to the drive shaft of the internal combustion engine and supports the rotor in a relatively rotational manner. A hydraulic chamber is partitioned by a vane and is disposed between the rotor and the drive member. The drive member includes an outer rotor forming the hydraulic chamber together with the rotor, a housing member including a front plate portion joined to one axial end of the outer rotor and a tubular portion linked the front plate portion and positioned on the outer radial side of the outer rotor, and a rear plate member joined to the other axial end of the outer rotor and to the housing member.
