ABSTRACT:
A drive arm is guided in a play-free and low-friction manner in a guide slot in a driven arm. The guide slot has two side edges which are arranged in displaced relationship with each other. Arranged on the driven arm are two rolling members, wherein a respective rolling member is associated with each side edge. At least one of the side edges is in the form of a spring bar portion so that the two rolling members roll against their side edges under a spring biasing effect.
