PROBLEM TO BE SOLVED: To provide a valve opening/closing timing control device capable of performing control in consideration of the pressing force of a pressing mechanism.SOLUTION: This valve opening/closing timing control device includes a drive side rotating body rotated in synchronous with the crankshaft of an internal combustion engine, a driven side rotating body which is disposed coaxially with the drive side rotating body and rotated in synchronous with the camshaft for valve opening/closing of the internal combustion engine, the pressing mechanism for pressing the driven side rotating body against the drive side rotating body in the direction of the advance-angle phase, and a fluid control mechanism for controlling the supply amount of a working fluid from a pump for supplying the working fluid into a fluid pressure chamber formed by the drive side rotating body and the driven side rotating body. A control unit controls the fluid control mechanism so that the relative angle of the driven side rotating body to the drive side rotating body is set to a predetermined target angle based on the relative angle, the temperature of the working fluid, and the discharge pressure of the pump. |
