Actuating device for transmission

The invention relates to an actuating device (10) for a transmission, comprising: an adjusting element (11) which can be rotationally moved starting from an actuator; at least one actuating element (17) which is arranged on one side of the adjusting element (11) and which can be moved in a translational manner depending on a rotational movement of the adjusting element (11); rolling bodies (18) which are arranged between the adjusting element (11) and the respective actuating element (17) in such a way that each rolling body engages in a ramp-shaped groove (19) of the adjusting element (11) and in a ramp-shaped groove (20) of the respective actuating element (17). The rolling bodies (18) arranged between the adjusting element (11) and the respective actuating element (17) are arranged in at least two concentric rolling body rings (21a, 21b). Alternatively or additionally, a support body (24) for supporting the adjusting element (11) on the housing-side base element (23) is arranged in at least two concentric
