A shifting device for the shifting of a transmission with a shifting shaft ( 2 ), upon which a multiplicity of shifting forks ( 8, 10, 12, 14 ) are placed in an axial, slidable manner for the carrying out of a shifting procedure, with a selection apparatus ( 28, 30, 32, 42, 44, 46 ) for the choice of the shifting fork from the multiplicity of shifting forks for the carrying out of the shifting procedure and with a blocking mechanism ( 52 ) for the prevention of the movement of non-chosen shifting fork. The blocking mechanism is to be found on an additional shaft ( 46 ) which is parallel to the shifting shaft, upon which the elements of the selection apparatus are provided. An actuator ( 60 ) exists which axially displaces the shifting shaft for the carrying out of the shifting procedure and another actuator ( 48 ) is provided, which causes to rotate the additional shaft for the choice of a shifting fork and for the prevention of the movement of non-chosen shifting forks.
