    摘要: A handwheel assembly comprising a plastic outer shroud formed with a radial lug disposed for register with a radial channel or slot formed in a driven pulley to prevent relative rotary movement therebetween. The shroud is concentric with the pulley, which includes a hub that extends through and partly beyond a central opening formed in the shroud for receiving a push-on retainer having prongs that engage the pulley hub thereby to secure it axially relative to the shroud.
