ABSTRACT:
An operating device for actuating the shift mechanism in multi-ratio gear transmissions in motor vehicles, incorporating a shift rail (2) which is moveable in parallel to the gear axes and arranged in a transmission housing (30), this shift rail carries coupling devices (16, 18, 20, 22, 32, 42, 46, 50). The coupling devices form a connection between the shift rail (2) and the shift forks (4) of the engaging gears and, at the same time, block the shift forks (4) of the non-engaging gears. The coupling devices (16, 18, 20, 22, 32, 42, 46, 50) have detents (22, 26, 32, 36, 42, 60) by which the engaged gears can be blocked in their engaged position.
