ABSTRACT:
A drive means of a rotary potentiometer is arranged to work trouble-free in the case of misalignment between the rotary axis of the rotating body and the rotary axis of the driving member. Teeth are arranged in the rotating, or rotary body, the crests of which teeth are directed to the rotary axis. The driving member is adjacent to the one flank of the one tooth and the one flank of the other tooth. The flanks of the teeth are involutely rounded off, so that the applied torque remains substantially constant in event of any misalignment of the driving member axis with respect to the body axis.
