Abstract: 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.

Abstract: In a positive torsion angle region in which a torque is transmitted from an engine side, a small hysteresis torque is generated at all times. Therefore, torsional vibrations of a small amplitude occurring during idle operation can be effectively attenuated by the small hysteresis torque, without switching to a large hysteresis torque, for example, during idle operation of the engine. As a result, the driver can be prevented from feeling uncomfortable due to switching to a large hysteresis torque during idle operation, and drivability can therefore be improved.
