Abstract:
A valve timing control apparatus is provided with at least one of: an advance-angle control starting device configured to start to control a relative rotational phase of a camshaft with respect to a crankshaft to an advance side when an internal combustion engine starts and when a valve lift amount associated with an intake valve or an exhaust valve increases; and a delay-angle control starting device configured to start to control the relative rotational phase to a delay side when the internal combustion engine starts and when the valve lift amount associated with the intake valve or the exhaust valve decreases. It is possible to appropriately release engagement by a locking mechanism between a first rotating body configured to rotate synchronously with the camshaft and a second rotating body configured to rotate synchronously with the crankshaft.
