Abstract
An improved sprag clutch is disclosed. A retainer for the sprags is generally U-shaped in cross-section. Legs at each axial end of the retainer extend radially outwardly of a central planar portion, which has notches to position the sprags. The U-shaped cross-section allows the use of a thin metal for forming the retainer body. A disclosed sprag has a single central spring notch at its inner periphery, and a solid contact surface at its outer periphery.
