The bushing structure comprises an outer metal fitting connected to the suspension member, an inner cylindrical metal member in which the fulcrum shaft is inserted, and an annular resilient member secured to the outer periphery of the inner cylindrical metal member and press-fitted in the outer metal fitting together with the inner cylindrical member. The bushing structure further comprises a plurality of radial stop rings positioned within the annular resilient member in spaced relation with one another axially of the annular resilient member. The bushing structure may preferably further comprise one or two annular axial stop members each including a stop ring embedded therein. The axial stop member is positioned on the respective end portion of the resilient member. The annular resilient member in a preferred form of the bushing structure has a plurality of annular grooves formed outwardly of the radial stop rings.
