ABSTRACT:
A freewheel of the cam type has a series of jamming cams 1 held by a cage 4 between a shaft 3 and an outer sleeve 2. The cams 1 are held in recesses 5 in the cage, which is a single integral moulding, by an integral spring strip 9 which extends around the outer periphery of the cage 4 and has elastic tabs 10 which project into the recesses 5 and bear against circumferentially extending surfaces 11 on the cams 1. They thus exert a substantially radial force 12 and a reaction on the contact line 13 to produce a torque 8 on the cams. The spring strip 9 is fixed angularly and axially with respect to the cage 4 by lugs 15 on the cage 4 fitting in openings 16 in the strip.
