MOTOR DEVICE MOUNTED ON MOBILE BODY AND MOBILE BODY HAVING THE MOTOR DEVICE MOUNTED THEREON

摘要

In a motor device (300) mounted on a mobile body, a pressurizing mechanism for pressurizing the inside of a motor chamber (14) where a motor is placed is rotationally driven by an engine (20) that is drive means for driving the mobile body. The motor device (300) has a compressor (30) for producing compressed air for pressurizing the motor chamber. When the engine (20) is operated, compressed air from the compressor (30) is almost constantly sent into the motor chamber (14) via piping (72).
