Abstract: PURPOSE: A mechanism for downwardly moving an engine is provided to prevent an engine from making in contact with the important part of a driver by moving the engine downward even though the engine is pushed to the driver's seat in a front collision of a vehicle. CONSTITUTION: A hydraulic actuator(3) consists of a hydraulic cylinder and a piston support member having a front end fixed to an engine(1). When the hydraulic pressure is applied to the hydraulic cylinder, the piston support member is lifted up and the engine is fixed with proper height. Oil is supplied to the hydraulic actuator by an oil pump(7) from an oil tank. When a sufficient amount of oil is supplied, a solenoid valve(9) isolates a pipe(8) to prevent the oil from flowing out of the hydraulic cylinder. A piezoelectric sensor(10) outputs an electric signal by detecting a shock applied to a vehicle body in a front collision of the vehicle. According to the electric signal, the solenoid valve opens the pipe to flow the oil in the hydraulic cylinder to the oil tank. The piston support member is descended and the engine is positioned on a lower part. Therefore, the engine does not injure the upper half of driver's body even though the engine is pushed toward the driver's seat by a shock in the front collision.
