関の吸・排気バリプ開閉時期制御装置。 A camshaft having a cam that opens and closes intake and exhaust valves of an internal combustion engine is coupled to a crankshaft via a winding member, and a drive wheel that rotationally drives the camshaft is rotatably supported at a predetermined angle with respect to the camshaft. , a hydraulic actuator that rotates the camshaft relative to the drive wheel according to the pressure of a hydraulic medium introduced into a hydraulic chamber; and a hydraulic pressure that connects the hydraulic chamber of the hydraulic actuator and a hydraulic medium supply source. The relative rotational position of the camshaft with respect to the drive wheel is determined by increasing the hydraulic pressure in the hydraulic chamber by closing the medium passage, or by decreasing the hydraulic pressure in the hydraulic chamber by causing the hydraulic medium to flow outside from the hydraulic medium passage. In an internal combustion engine intake/exhaust valve opening/closing timing control device comprising a flow rate control valve for controlling the camshaft, a drive wheel and a hydraulic actuator are arranged at one end of the camshaft, and a flow rate control valve is disposed at the other end of the camshaft. What is claimed is: 1. An intake/exhaust varip opening/closing timing control device for an internal combustion engine, characterized in that a hydraulic medium passage is provided inside a camshaft and connects to a flow control valve of a hydraulic chamber of a hydraulic actuator.
