A drive mechanism that drives an axially moving portion in an axial direction includes a drive portion that reciprocates a first member along an intersecting direction that is a direction that intersects the axial direction, a conversion portion that converts a reciprocating motion of the first member along the intersecting direction into a reciprocating motion of a second member along the axial direction, and a connecting portion for connecting the second member and the axially moving portion such that the axially moving portion reciprocates along the axial direction as the second member reciprocates along the axial direction.

An actuator device for a gearbox of a motor vehicle includes a plurality of selector shafts displaceable in a first direction between a plurality of selection positions and in a second direction between a plurality of shifting positions and which each have a connecting element that is operatively-connected in at least one of the selection positions with at least one selector rail of the gearbox for transferring a movement of the selector shaft in the second direction onto the selector rail. The selector shafts are mounted relative to each other to be movable relative to one another in the first direction and are fixed to relative to each other in the section direction The selection positions of the selector shafts are independently adjustable by of a plurality of first adjusting elements and wherein the selector shafts can be displaced together between the shifting positions by means of a second adjusting element.

The invention is to suppress the increase of axial lengths of each input shaft and each output shaft and increase the number of gear shift stages. A transmission device transmits a driving force of a crankshaft from a first transmission to a drive wheel side through a second transmission. The first transmission is provided with a first countershaft to which the driving force from the crankshaft is transmitted, and a first drive shaft to which the driving force of the first countershaft is transmitted. The second transmission is provided with a second countershaft to which the driving force of the first drive shaft is transmitted, and a second drive shaft to which the driving force of the second countershaft is transmitted and which transmits the driving force to the drive wheel side. The first and second transmissions are disposed side by side in a front/rear direction. Each of the first and second transmissions is set to have a plurality of gear shift stages.
