Abstract

An overrunning clutch comprising two concentric machine components (1,2) rotatable relative to each other and having locking surfaces (13,14) formed on their mutually facing peripheral surfaces, and, arranged therebetween, a plastic cage (4) comprising end rings (15) connected to each other by crossbars (16), pockets (17) for locking elements (3) spring-urged against the locking surfaces (13,14) being formed between circumferentially adjacent crossbars (16), the plastic cage (4) further comprising at least one radial projection (19) which engages into a recess (20) of one of the machine components (2) to prevent rotation of the plastic cage (4) relative to this machine component (2), characterized in that the radial projection (19) is arranged on a crossbar (16).
