Abstract
Abstract A resilient bushing includes an inner rigid sleeve, an outer concentric rigid sleeve having a radially outwardly extending flange at one end thereof, and an elastomeric tubular insert held under radial compression between the inner and outer sleeves. The tubular insert has a radially outwardly extending flange at the end corresponding to the flanged end of the outer sleeve. On the tubular insert between the flange of the outer sleeve and that of the tubular insert there is fitted an annular disc of a synthetic resin.
