ABSTRACT:
A speed variator pulley comprises a pair of annular plates mounted on a hub. One of the plates is axially movable relative to the other by means of a diaphragm which, by its peripheral portion forming a dished plate spring, axially bears to rock against the said movable plate. Axially interposed between the diaphragm and the movable plate in order to form a rocking axial support, is a spacer of elastic material, which on the one hand is fastened both axially and circumferentially to the diaphragm and which on the other hand is fastened at least axially to the movable plate.
