装置。 A drive wheel that transmits the rotational driving force of the crankshaft is rotatably supported at a predetermined angle with respect to the camshaft on a camshaft that has a cam that opens and closes the intake and exhaust valves of the internal combustion engine, and a drive wheel that transmits the rotational driving force of the crankshaft is rotatably supported at a predetermined angle with respect to the camshaft. An intake/exhaust valve for an internal combustion engine, which is equipped with a hydraulic actuator for setting a relative angular phase between the two, and an electromagnetic actuator that controls a flow rate control valve for hydraulic fluid of the hydraulic actuator by an output shaft. In the opening/closing drive device, the output shaft of the electromagnetic actuator is disposed approximately parallel to the camshaft, and the inlet and outlet provided in the electromagnetic actuator are connected to the internal output shaft so as to open into the engine at an upper position and a lower position of the output shaft, respectively. An intake/exhaust valve opening/closing timing control device for an internal combustion engine, characterized in that the valves communicate through an end movement space.
