Power transmitting apparatus and power transmitting apparatus assembly method

A power transmitting apparatus comprising:

• an electric motor shaft that is connected to a rotor of an electric motor which serves as one driving source of a vehicle;
• an input shaft which is arranged parallel to the electric motor shaft and transmits power to and from an internal combustion engine which serves as another driving source and is positioned on one side in the axial direction;
• an input shaft rotating member which is provided on an end portion of the input shaft that is on the side opposite the internal combustion engine side and which transmits at least one of the power from the input shaft or the power from the electric motor shaft to a drive shaft of the vehicle;
• a pump which has a pumping apparatus that is driven by the power from the internal combustion engine and pumps lubrication oil, and a pump main body that houses the pumping apparatus;
• and
• a case that houses the input shaft and the input shaft rotating member, the electric motor being arranged on the opposite side of the input shaft rotating member from the internal combustion engine in the axial direction, wherein
• the pumping apparatus includes a rotating shaft which is coupled to the input shaft and rotatably driven by the power from the internal combustion engine, and a pump rotor which is coupled to the rotating shaft, rotates together with the rotating shaft, and pumps the lubrication oil;
• and
• the input shaft rotating member is rotatably supported by the case via a bearing, and at least part of the pump rotor is arranged radially inward of the bearing in a same plane perpendicular to the rotating shaft.
