One-way clutch with end alignable ribbon spring

摘要

A ribbon spring for use in a sprag-synchronized one-way clutch includes an elongated metal thin plate which is formed with a plurality of sprag insertion holes at a predetermined pitch. The ribbon spring is bent linearly in at least at one location or in a curved form at least partly at least at one end portion, so that the ribbon spring defines a circle which is substantially equal to a true circle when assembled into a one-way clutch.
