Abstract
A roller clutch cage combines the advantages of easily molded plastic cross bars with the strength of steel side rails, but is assembled without the need for any rivets or the deformation of any metal part. Cooperating flexible arms and fulcrum surfaces molded to each end of each plastic cross bar tightly grip the side rails, providing a very rigid structure.
