Disclosed herein is a unitary bushing and retainer assembly for pivotally connecting a first work piece having a shank portion, such as a connecting rod, with a second work piece having an aperture, such as a lever. The bearing and retainer assembly includes a sleeve portion which fits snugly inside the lever aperture and has a bore for pivotally receiving the shank portion of the connecting rod. After the connection has been completed, withdrawal of the connecting rod from the sleeve portion is prevented by an annular rib which is located on the sleeve portion bore and is received in an annular recess provided in the shank portion of the connecting rod. A pair of opposed arms extending radially from one end of the sleeve portion and having locking elements which snap over the opposite edges of the lever secure the bearing and retainer assembly and the connecting rod on the lever.
A unitary bushing and retainer assembly comprising a first work piece including a shank portion which has a recess, a second work piece including a main body and an ear which is integrally connected to said main body in generally spaced parallel relation to said main body, said main body and ear having therein respective coaxial apertures, and a unitary bushing and retainer comprising a sleeve portion extending through both of said second work piece apertures and including a bore extending coaxially with said apertures and pivotally receiving said shank portion of said first work piece, retainer means located between said apertures of said second work piece, on said sleeve portion bore and engaging said recess in said shank portion of said first work piece, thereby positively resisting withdrawal of said shank portion from said bore, and means for preventing movement of said second work piece axially of said shank portion of said unitary bushing and retainer.
An assemblage comprising a rod-like element including a shank portion having an annular recess, a member having a main body and an ear which is integrally connected to said main body in generally spaced parallel relation thereto, said main body and said ear having respective coaxial apertures, and a unitary bushing and retainer assembly pivotally connecting said element with said member and including a sleeve portion extending in said apertures of said member and having a central bore receiving said element shank portion so as to afford pivotal movement therebetween, said sleeve portion bore having an annular rib located between said main body and said ear and fitting into said shank portion recess to positively resist withdrawal of said shank portion from said sleeve portion bore, an arm extending radially from one end portion of said sleeve portion, and means for locking said arm onto said member to restrain relative axial movement of said member and said element.
