PROBLEM TO BE SOLVED: To improve the cooling performance of a cooling device provided on a motor which is used for driving and regenerative braking a vehicle. SOLUTION: A cooling space 16 is provided in a part of a motor case 9 in circumferential direction which case constitutes a shell of motors 1 and 2. A heat accumulating member 17 is arranged on the circumferential part except for the part provided with the cooling space 16. When the temperature of a stator 8 on which a coil 13 is wound rises due to heating of a coil 13, the cooling space 16 and the heat accumulating member 17 cool the stator 8.
