PURPOSE:To prevent displacement and vibration of a power unit when torque changes, by providing a means for detecting a decelerating state of an engine and controlling a mount property to a hard side when a decelerating state equal to or greater than a prescribed value is detected. CONSTITUTION:A brake unit 50 is provided with a hydraulic pressure 53 for sensing a hydraulic pressure when an oil actuator 52. The detected value of the hydraulic sensor 53 is applied to a control unit 21. The control unit 21 determines whether the detected value is equal to or greater than a prescribed value. As a result, when it is determined that it is in a decelerating state equal to or greater than the prescribed value, a rotary valve 13 is closed to make a mount property of mount members 7A, 7B hard. With this arrangement, the displacement and vibration of a power unit can be effectively prevented when a transient large torque change happens in decreasing a speed.
