Abstract: A cam assembly for a hoist mechanism includes a cam member, a pair of springs and an input shaft. The cam member has a cavity defined by an inner periphery of a side wall and floor. Cutout portions extend radially outwardly from the inner periphery of the cavity. The springs include a bow-shaped body portion positioned between first and second connection end members. The body portion further includes an outwardly extending detent, each detent extends into a cutout of the cam member to operatively connect the cam member to the springs. The input shaft has a through hole. The first connection end members of each spring are inserted into the through holes of the input shaft, thereby operatively connecting the springs to the input shaft with a reduced number of components.
