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 30. The drive
member includes an outer rotor forming the hydraulic chamber together
with the rotor 2, 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.
