A hybrid saddle-type vehicle is provided with a power transmission mechanism for transmitting a power of an internal combustion engine to a drive shaft of a rear wheel from one side of a swing arm in a widthwise direction of a vehicle, and an electric motor disposed in the other side in the widthwise direction and for transmit a driving force from the other side in the widthwise direction. A motor housing of the electric motor is supported on an extension portion extending in the other side in the widthwise direction from a portion of the drive shaft to which the rear wheel is mounted, via a pair of bearing sections disposed on both sides of the motor housing in the widthwise direction. The rotor is rotatably supported by the drive shaft between the pair of the bearing sections.
