PURPOSE:To make the flexibility quantity of a mount largely securable in a direction of positive load, by making negative load act on this mount with dead weight of a power unit. CONSTITUTION:A power unit 4 is supported by first and second rubber mounts 5 and 6 to be set up in a distant position, in a direction of a crankshaft or an output shaft of this power unit 4, and a third rubber mount 7 to be set up as offset in a width direction of the power unit 4 in relation to the crankshaft. Therefore, negative load comes to act on the third mount by dead weight of the power unit in consequence, so that a spring constant of the third mount can be softly set in a wide range, thus a vibration reduction at the tie of power increment at acceleration or the like is promotable. |
