PROBLEM TO BE SOLVED: To provide a motor cooling inside a terminal box by wind of a fan for cooling a motor body. SOLUTION: A shape of a fan cover 3 or the terminal box 5 is improved. Thus, the terminal box 5 is cooled by wind Fa for cooling a motor. A gap (including 10z) is provided between a side (including 5z) of the terminal box 5 and the fan cover 3. Wind Fa from the fan 4 is discharged via the gap, wind is applied to the side of the terminal box 5 and the terminal box 5 is cooled from a surface thereof. Further, by providing an entrance port and an exhaust port on a lower surface of the terminal box 5, wind can be taken from the fan 4 into the terminal box via the entrance port to be discharged from the exhaust port, the inside of the terminal box 5 can directly be cooled.
