A power transmission structure of a vehicle, which is provided with a first rotor, a second rotor, and a metallic cylinder. In this power transmission structure, the reduction shaft and the second rotor shaft receive reaction force from the cylindrical metallic member in radially opposite directions. The cylindrical metallic member is deformable elastically in a radial direction and press-fitted in a part where the reduction shaft and the second rotor shaft of a second electric motor overlap each other in the radial direction adjacent to a spline fitting part of the reduction shaft and the second rotor shaft. Therefore, misalignment between the axis of the reduction shaft and the axis of the second rotor shaft is restrained, and generation of tooth hitting sound is thus restrained. Since the cylindrical metallic member has high rigidity and is restrained from being deformed in a rotation direction, responsiveness of torque transmission is improved.
