Abstract
Abstract A one-way clutch including an outer member containing a bore surrounding a spaced inner member with a full complement of rollers in side-to-side engagement located around the inner member between the two members. One or more control members may be spaced between the rollers to urge the rollers in a given rotary direction against wedging ramps provided on the surfaces of one of the members to engage the clutch for driving purposes. The outer member may have flanges or washers extending radially inwardly to overlap the longitudinal ends of the inner member.

Claim 1
Independent Claim
