PURPOSE:To improve vibrative noise performance when an engine is loaded and not loaded, by interposing elastic materials between a power unit and a car body and arranging torque rods in both sides of the center of gravity of the power unit as a supporting device of the engine. CONSTITUTION:When a power unit 4 is operated under the no-load condition, vibration is generated in the power unit 4 by idle running of an engine 2. This fine vibration is weakened while being propagated in torque rods 6, 16 and a member 12 while absorbed to be damped by elastic materials 26, 30 provided to the member 12, and the vibration is never transmitted to a car body side also a noise due to the vibration is not generated. While at loaded time of the engine in starting and deceleration or the like, large vibration is to be generated in the power unit 4 by load torque with the center of gravity G as the center. These vibrations are weakened to be supported by the torque rods 6, 16, then the rest of fine vibration also reaches the elastic materials 26, 30 and is absorbed. |
