Transmission for vehicle

A transmission for a vehicle, comprising:

• a transmission unit for receiving a transmission command for a vehicle;
• and
• a driving unit for generating a driving force for switching a posture of the transmission unit based on whether a preset condition is satisfied,
• wherein the driving unit comprises:
• a first stator for generating magnetic flux;
• a first rotor including a first inner permanent magnet and a second inner permanent magnet axially arranged with a predetermined axial spacing therebetween along a rotation axis, and configured to be rotated by the magnetic flux transferred to the first inner permanent magnet;
• an outer permanent magnet provided in a number different from a number of the second inner permanent magnet;
• and
• a second rotor configured to rotate along a magnetic force path between the second inner permanent magnet and the outer permanent magnet at a number of revolutions per unit time that is different from a number of revolutions per unit time of the first rotor,
• wherein the driving force transferring unit comprises:
• a wire;
• a driving pulley rotatable by a driving force of the driving unit, wherein the wire is wound around an outer circumferential surface of the driving pulley;
• and
• a driven pulley rotatable by switching the posture of the transmission unit, and wherein a rotational force is exchanged between the driving pulley and the driven pulley via the wire.
