Abstract:
A bushing adapted to be press-fit into a top aperture and a bottom aperture of a bushing-attaching hole to mount a suspension cross-member to a vehicular body via a stud and nut arrangement, said bushing comprising:an outer member including an outer main body having a substantially cylindrical shape with an axial length shorter than one half the axial length of the bushing-attaching hole, and an outer flange extending in a radially outward direction from an axial end of said outer main body; an inner member including an inner main body having a substantially cylindrical shape with an axial length longer than one half the axial length of the bushing-attaching hole with an external diameter smaller than the internal diameter of said outer main body, an inner flange extending in a radially outward direction from an axial end of said inner main body with an external diameter larger than the internal diameter of said outer main body, and a through hole through which the stud is inserted, said inner member being inserted into said outer member so that said inner flange and said outer flange lie coaxially relative to each other; an elastic member disposed between said inner member and said outer member and adhered to each one of said inner main body, said inner flange, said outer main body, and said outer flange, wherein said elastic members is substantially free from elastic deformation to provide a predetermined clearance between the axial end of said inner member when said bushing is press-fit into the bushings-attaching hole until the outer flanges contact the suspension cross-member before said bushing is fixed by the stud and nut arrangement, and wherein said elastic member is elastically deformed by tightening the stud and nut arrangement so that said inner member is axially displaced with respect to said outer member so that they abut each other when the suspension cross-member is mounted to the vehicle body.
