開閉時期制御装置。 A driven gear is formed on the outer periphery of a camshaft having a cam for opening and closing an intake valve or an exhaust valve, and a driving gear formed on the inner periphery of a rotation transmitting body driven by an engine crankshaft is meshed with the driven gear. and an internal combustion engine in which the phase of the camshaft is changed relative to the engine crankshaft by displacing the rotation transmitting body in the axial direction of the camshaft, thereby changing the opening/closing timing of an intake valve or an exhaust valve. A valve timing control device for an internal combustion engine, comprising a biasing means for biasing the camshaft against the rotation transmission body in a direction opposite to the rotational direction of the camshaft.
