Claims3
A power transmission device for a vehicle, the power transmission device comprising:
- a rotor shaft supported by a pair of first bearings and configured to rotate, the rotor shaft including first spline teeth;
- a gear shaft supported by a pair of second bearings and configured to rotate about an axis common to the rotor shaft, the gear shaft including second spline teeth, the second spline teeth being spline-fitted to the first spline teeth;
- and
- a rattling suppression member press-fitted into a portion where the rotor shaft and the gear shaft overlap each other in a radial direction and where neither the first spline teeth nor the second spline teeth are provided, the rattling suppression member provided one of between a first shaft end portion and the gear shaft and between a second shaft end portion and the rotor shaft,
- the first shaft end portion being a portion, protruding to the gear shaft side from one of the pair of first bearings, of the rotor shaft, and
- the second shaft end portion being a portion, protruding to the rotor shaft side from one of the pair of second bearings, of the gear shaft.
