PROBLEM TO BE SOLVED: To provide an electric motor driving device meeting restriction of a space of a vehicle. SOLUTION: A reduction gear section 31 of the electric motor driving device 1 includes: a first shaft 33 including a tubular outside rotary shaft 33o coaxially arranged with a motor side rotating member 22 and an inside rotary shaft 33i inserted into the outside rotary shaft 33o; a second shaft 34 arranged in parallel with the first shaft 33 to transmit rotation to wheels; a first reduction gear part G1 for reducing rotation of the inside rotary shaft 33i at a first reduction gear ratio to transmit the rotation to the second shaft 34; and a second reduction gear part G2 for reducing rotation of the outside rotary shaft 33o at a second reduction gear ratio different from the first reduction gear ratio to transmit the rotation to the second shaft 34. A connecting/disconnecting part 21 includes a first clutch C1 connecting the motor side rotating member 22 and the inside rotary shaft 33i to each other and a second clutch C2 connecting the motor side rotating member 22 and the outside rotary shaft 33o to each other.
