ABSTRACT:
In a drive rod lock the drive rod is moved from a lock cylinder through a step-down gearing between an open position and a closed position and vice versa. A coupling of the step-down gearing to the drive rod is proposed which permits, in the case of rotation of the lock cylinder through 2.degree..times.360.degree., of shifting the drive rod from the open position into the closed position against displacement, without a torque being introduced due to the blocking forces into the step-down gearing and thus the lock cylinder.
