Abstract

The invention relates to a device (1) for overcoming play between a first component (2) and a second component (3) wherein a first wedge (4) is arranged so as to be movable relative to a second wedge (5) in such a manner that via a spring force a tensioning device (11) exerts a frictionally engaging force against the second component (3).
