    Abstract: Provided is a novel valve timing control apparatus capable of reducing an axial length and of reducing a thickness of a housing. A valve timing control apparatus for an internal combustion engine includes a timing pulley to which a rotational force is transmitted from a crankshaft via a timing belt, a housing configured to be rotated by the timing pulley and including a plurality of shoes provided on an inner peripheral surface thereof, and a vane rotor relatively rotatably contained inside the housing and configured to be rotated in synchronization with a camshaft. The vane rotor includes a vane forming a retard angle oil chamber and an advance angle oil chamber inside the housing in cooperation with the plurality of shoes. A predetermined interval is provided between an outer peripheral portion of the housing and an inner peripheral portion of the timing pulley. An outer peripheral portion of a housing main body of the housing and the inner peripheral portion of the timing pulley are coupled with each other via a plurality of coupling beam portions with intervals in a circumferential direction. The housing main body, the timing pulley, and the plurality of coupling beam portions are integrally formed.
