PCT No. PCT/EP90/01005 Sec. 371 Date Dec. 10, 1991 Sec. 102(e) Date Dec. 10, 1991 PCT Filed Jun. 25, 1990 PCT Pub. No. WO91/00448 PCT Pub. Date Jan. 10, 1991.In a gearshift device of a multiple-gear transmission of a motor vehicle in which gear shift gates are selected by the rotation of a central selector shaft (2) and gear steps are engaged by the subsequent axial movement thereof. The selector shaft (2) is non-rotatably and axially movable via roller bodies in a hub (4) of a lever-type selector rocker (3). Several rows of balls (12) extending axially, which with a part of their surface positively engage in guide grooves (10 and 11) both of the hub (4) and of the selector shaft (2), are arranged in a cage (13) situated between hub (4) and selector shaft (2) to prevent backlash between the hub (4) and the selector shaft (2) in a peripheral direction in a radial direction.
