PURPOSE: A rear axle bush fits a ride comfort and operability, simultaneously, by improving the structure thereof. CONSTITUTION: A rear axle bush comprises an outer tube(52), an inner tube(54), a first rubber elastic body(56) and second rubber elastic bodies(58). The inner tube(54) is disposed in the outer tube(52). The first rubber elastic body(56) is closely interposed between the inner tube(54) and the outer tube(52). The second rubber elastic bodies(58) are inserted among the first rubber elastic body(56), the inner tube(54) and the outer tube(52), have a predetermined clearance(S) with the inner tube(54) or the outer tube(52) and are harder than the first rubber elastic body(56). Therefore, a vertical impact transmitted to the rear axle is absorbed to the soft first rubber elastic body(56) and a side impact is absorbed to the hard second rubber elastic body(58).
