The invention relates to a gear shifting device (2) comprising a single-rod gear shifting system in a housing of a motor vehicle manual gearbox. Said device comprises a central gearshift shaft (32) and fork-type gear shifting elements in the form of gear shifting swinging forks or gear shifting forks (4, 6, 8, 10) which are optionally and individually engaged with the gearshift shaft (32) by rotating the same (32), and which carry out a gear shift of the selected gear shifting element by means of displacement of the gearshift shaft (32) along a rotational axis (34) of said gearshift shaft (32). Said gear shifting device (2) comprises a first element (58, 60) which is connected to the gearshift shaft (32) and which co-operates with a second element (62) fixed in the housing, in order to define the rotation of the gearshift shaft (32). The second element (32) fixed in the housing comprises a number of slits (66) of a defined width, corresponding to the number of gear shifting passages, said slits co-operating with two pins (58, 60) which are arranged on the gearshift shaft (32) and which form the first element. Each one of said pins (58, 60) engages in the slit (66) corresponding to the respective gear shifting passage during the rotation of the gearshift shaft (32), when one of the gear steps is positioned in the selected gear shifting passage. |
