PURPOSE:To reduce vibration of a vehicle body in front and rear directions, by connecting the vehicle body with an axle case through upper, lower links and providing bushed with respective connecting portions and setting a ratio of rigidity of the bushes on the upper and lower link sides at a specific value. CONSTITUTION:A rear axle case 2 integral with a differential gear case 1 has upper and lower portions with upper and lower brackets fixed thereto and the rear ends of a upper link 6 and a lower link 12 are axially supported by the brackets 3, 4 through bushes 5, 11 of an elastic material. The front ends of the respective links 6, 12 are swingingly supported by upper and lower brackets 10, 14 on the side of a vehicle body fixed to the vehicle body 9 through bushes 8, 13 which are identical with the bushes 5, 11. As a result, an accelerator case 2 is swingingly supported with respect to the vehicle body 9. The rigidity of the respective bushes 5, 8, 11, 13 are set in such a manner that a ratio of the rigidity KU of the bushes 5, 8 on the side of the upper link to the rigidity KL is approximately KU/KL<=1/4. |
