Abstract

A rotatable and longitudinally shiftable piece in a motor vehicle gear wheel change box interacts with three abutting shift rails. The longitudinal displacement of one shift rail blocks the two other shift rails. A spring engages in all shift rails in a form-fitting and elastic manner and locks them with respect to one another and with respect to the gearbox in the center position and in the respective left or right shifting position.
