PURPOSE:To obtain a high degree of shock- and vibration-absorbing performance, in a unit in which an engine is supported by a frame via vibration-proof rubber at two spots in front part and one spot at rear part, by improving the arrangement configuration of the front & rear vibration-proof rubber. CONSTITUTION:When an engine 2 and a clutch housing 6, both of which are combined as one boby on a frame 1 whose frame structure consists of the right and left frame boards 1R and 1F, are supported by vibration-proof rubber 4 and 5, the vibration-proof rubber 4 is installed in nearly a form of ''?'' as viewed from its front at a little forward position from position G, the center of gravity of the engine(2)-clutch(6)-combination. The rear end of the clutch housing 6 is supported by a piece of vibration-proof rubber 5. The vibration proof rubber 5 is formed into nearly a shape of ''?'' as viewed from its side. With these contrivances, use of a small quantity of vibration-proof rubber 4 and 5 can effectively absorb abnormal engine vibration in both lateral and longitudinal directions. |
