When a shift lever is moved to a shift position corresponding to a first gear position etc., the shift lever is urged by its own weight to a neutral position, which is disadvantageous for the shift lever in terms of gear slip-out after shifting. However, a counter mass is moved to a position reached by turning a second predetermined angle, larger than a first predetermined angle corresponding to the neutral position, downward with respect to a vertical line passing through a center of turn of the counter mass. Meanwhile, the shift lever is urged by the weight of the counter mass in the direction away from the neutral position, so that gear slip-out after shifting can be prevented.

A gearbox for a motor vehicle, includes multiple gears, a housing, an interior space enclosed by the housing, a gearshift clutch located in the interior space, through which a gear can be shifted, and a shifting device for transmitting an external actuating force acting outside the housing for shifting to the gearshift clutch, the shifting device having an inner shifting part in the interior space, a first introduction element which engages through a first opening provided in the housing for guiding the external actuating force to shift the gear to the inner shifting part, a shifting mass arranged outside the housing which is moved during gear shifting, and a connecting element different from the first introduction element with which the shifting mass is connected to the inner shifting part, the connecting element engaging through a second opening different from the first opening in the housing into the interior space.
