Abstract
A valve opening/closing timing control apparatus includes: a driving side rotator configured to rotate synchronously with a crankshaft of an internal combustion engine; a driven side rotator disposed coaxially with a rotation axis of the driving side rotator and configured to rotate integrally with a valve opening/closing camshaft; a connecting bolt disposed coaxially with the rotation axis to connect the driven side rotator to the camshaft, and having an advanced angle port and a retarded angle port formed to extend from an outer peripheral surface to an inner space thereof, the advanced angle port and the retarded angle port communicating with an advanced angle chamber and a retarded angle chamber between the driving side rotator and the driven side rotator, respectively; and a valve unit disposed in the inner space of the connecting bolt.
