A roller pinion for rotating about a central axis generally includes a core having an axial bore at its center for mounting on a drive shaft and recesses extending the length of the core. The recesses define faces with a plurality of regularly distributed sectors extending between them. The roller pinion also includes a cage associated with a plurality of rollers. The cage extends around the outer peripheral surface of the core, and presents, facing the outer peripheral surface of the core, a concentric spherical inner surface that faces the recesses of the core. Protuberances are provided that extend into the recesses. The protuberances have faces positioned parallel to and facing the faces of the recesses. Metal strips arranged in bundles with elastomer material interposed between the strips are inserted in a space between the respective faces of one recess in the core and one protuberance of the cage.
