Provided is a transmission which is capable of outputting required power irrespective of the direction of rotation of an electric motor, and furthermore is capable of recovering energy with efficiency. A transmission device (3) for transmitting power coming from an electric motor (2) to an output shaft (11) connected to an axle (6) side, the transmission device (3) being provided with: a first input shaft (9) which is coaxial with a rotation shaft (2a) of the electric motor and rotates integrally with the rotation shaft (2a); a second input shaft (10) which is disposed in an externally fitted manner coaxial with the first input shaft (9); a first gear mechanism (17) by which the first input shaft (9) and the output shaft (11) can be connected with a first gear ratio; a selective fixing means (16) by which an idle gear which, of the gears of the first gear mechanism (17), is arranged on the output shaft (11) can be selectively fixed to the output shaft (11); a second gear mechanism (20) which connects the second input shaft (10) and the output shaft (11) at a second gear ratio different from the first gear ratio; and a connecting and disconnecting means (12) which implements and releases the connection between the rotation shaft (2a) and the second input shaft (10).
