ブ開閉時期制御装置。[Scope of Claim for Utility Model Registration] A drive wheel that transmits the rotational driving force of a crankshaft is rotatably supported at a predetermined angle with respect to a camshaft on a camshaft that has a cam that opens and closes intake and exhaust valves of an internal combustion engine, A hydraulic actuator is interposed between the drive wheel and the camshaft to set a relative angular phase between the two, and the output shaft, whose end is exposed inside the engine and receives an elastic restoring force on the fail-safe side, operates the hydraulic actuator. In an internal combustion engine intake/exhaust valve opening/closing drive device equipped with an electromagnetic actuator that controls a flow rate control valve for hydraulic fluid in a pressure actuator, there is a temperature sensor that detects the engine temperature, and a temperature sensor that detects the engine temperature based on the detection signal of the temperature sensor. means for stopping the operation of the electromagnetic actuator in at least one of a low temperature region below a first predetermined value and a high temperature region above a second predetermined value higher than the first predetermined value. Intake/exhaust valve opening/closing timing control device.
