PURPOSE:To make slippage between an elastic main shaft and an input shaft of rotational vibration smaller by lowering a spring constant along the rotational vibration direction of mount rubber at the side where each driving reaction of a propeller shaft and a drive shaft works in the same direction. CONSTITUTION:When each driving reaction of a propeller shaft 1 and drive shafts 3, 3 works thereon, an input shaft 10 of rotational vibration atendant upon a torque variation in a power unit P is tilted as shown in illustration. At this time, in both first and second mount rubbers 6, 7, the side where both driving reactions works in the same direction, namely, the first mount rubber 6 is made to set its spring constant to be higher in direction of the input shaft 10 of the rotational vibration but to be lower in direction of almost orthogonal with the input shaft 10. On the other hand, a spring constant of the second mount rubber 7 is set to be lower in direction of the input shaft 10 but to be higher in direction of almost orthogonal with the input shaft 10, therefore the spring constant of the second mount rubber 7 along the rotational vibration direction around the input shaft 10 is set higher than that of the first mount rubber 6.
