PROBLEM TO BE SOLVED: To provide an electric racing cart provided with a motor that effectively suppresses a temperature rise. SOLUTION: The electric racing cart is composed so that a motor 100 is mounted to a vehicle-body frame 2. The motor is provided with a body part having a plurality of first ventholes for discharging outside air, and a plurality of second ventholes for taking in outside air. An outside-air intake means 400 has an inlet and an outlet made to communicate with each other. The outside-air intake means is composed so that an opening face of the inlet and one of the outlet are almost orthogonal to each other while an opening area of the outlet is larger than a size that includes the plurality of second ventholes. The outside-air intake means is mounted to the motor 100 while including the plurality of second ventholes by the outlet. The inlet is directed in a traveling direction. COPYRIGHT: (C)2009,JPO&INPIT
