A shift device for a transmission consists of a shift sleeve (19), of a shift fork (63) engaging into the shift sleeve and of an actuator rotatable on a shaft (48) arranged transversely to the transmission shaft. In order to have a simple and reliable control which satisfies all functional requirements, - a cam (50, 50') with two flanks (73, 74) and with a flattening (75) at the maximum radius is provided on the shaft (48), - two lantern wheels (60, 61) cooperating with the cam (50) are provided at a fixed distance (70) from one another on the foot part (64) of the shift fork (63), so that - one lantern wheel (60) bears against one flank (73) and the other lantern wheel (61) bears against the other flank (74), and, in at least one end position, one lantern wheel (60, 61) bears against the flattening (75). |
