<p>Gripping apparatus comprises a plurality of axially tapered rollers (47) for engaging the gripped member; and a body having a cam surface (36) which is shaped so as to urge the rollers, when in use, against the gripped member when the rollers slide axially with respect to the cam surface. The cam surface is also shaped so as to urge the rollers, when in use, against the gripped member when the rollers roll along the cam surface.</p> |
