PURPOSE:To make sealing effect sufficient and to facilitate assembling at a low cost by covering both ends of a cylindrical sliding sleeve provided between an inside rubber elastic body and inner cylinder metal fittings in the connecting portion of a vehicular suspension or the like. CONSTITUTION:A bush assembly is a double bush structure consisting of a cylindrical inside rubber elastic body 4 and a cylindrical outside rubber elastic body 5 respectively fitted between inner cylindrical metal fittings 1, intermediate cylindrical metal fittings 2 and outer cylindrical metal fitting 3. A cylindrical sliding sleeve 6 for reducing the frictional force there between and allowing those relative is sliding is interposed between the inside rubber elastic body 4 and the inner cylindrical metal fittings. Both ends of the cylindrical sliding sleeve 6 is covered by an elastic dust seal 7. Thus, sealing effect becomes sufficient, assembling is easy and is supplied at a low cost. |
