Abstract
A return stop device with a freewheel having an internal ring, an external ring, and retaining elements arranged in an annular gap therebetween. A flange is provided at the attachment side and a housing part, between which the external ring is clamped, and a clamping device by which the external ring is pressed with its face between the flange and the housing part against a friction area, in order to generate a friction-fitting connection between the flange and the external ring. A release device is provided to at least partially overcome the contact pressure, in order to reduce or remove the friction-fitting connection. The release device includes an actuating organ, which acts upon a first gliding element, displaceable in an operating direction, to act upon a second gliding element, arranged displaceable perpendicular to the operating direction, that acts via a second wedge against the contact pressure upon the housing part.
