Electric power generating device for aircraft

An electric power generating device for an aircraft, which is driven by an output of an aircraft engine, the electric power generating device comprising:

• an input shaft to which a driving force of the engine is transmitted;
• a transmission arranged with the input shaft;
• an electric power generator arranged with the input shaft and the transmission and driven by an output of the transmission;
• a driving force transmission mechanism disposed on a first end side of the input shaft in an axial direction thereof, the driving force transmission mechanism being configured to transmit the output of the transmission to the electric power generator;
• and
• a casing including a mounting section on the first end side of the input shaft in the axial direction,
• wherein the transmission includes a transmission input section provided on a second end side of the input shaft in the axial direction, the transmission input section being configured to receive as an input a rotational driving force from the input shaft, and a transmission output section provided on the first end side of the input shaft in the axial direction, the transmission output section being configured to output to the driving force transmission mechanism the rotational driving force whose speed has been changed,
• wherein the driving force transmission mechanism has an inner space and the input shaft is inserted into the inner space, and supported by at least one bearing to permit rotation with respect to the transmission and the electric power generator;
• and
• wherein the input shaft is disposed between the transmission and the electric power generator.
