Abstract

The mechanism has a manual shift gate (3) axial-displaceably connected with actuators (5, 23). The actuators are axial-adjustably mounted on a twistable adjusting shaft (12) between adjusting devices (10, 17). One of the actuators has a contour (21) at a front side, which is provided in a direction of one of the adjusting devices. The contour is in operative connection with one of the adjusting devices via a counter-contour. The shaft is brought into engagement with and/or separable from a cam shaft (1) by an adjusting gear for twisting the shaft.
