Abstract
A invention relates to a chuck having a shank which provides two shank sections (,), forms a clamping section (,) at one end for clamping in place in a drive member and forms a tool mounting (,) at the other end for mounting a tool, in particular a screwdriver bit (,), having an elastic element between the clamping-side shank section (,) and the tool-mounting-side shank section (,) for permitting a stop-limited twisting capability of the clamping section relative to the tool mounting (,). To achieve a narrow type of construction, provision is made for the elastic element to be formed as a bending spring which is bendable transversely to the axis of the chuck and connects the two shank sections to one another.
