Abstract
A cooling device for an electric motor, comprising a cover which has a cylindrical-shaped main part which can house the electric motor, and a fan motor which is attached to the main part so as to blow air to the inside of the main part. The cover further has an abutting part which protrudes from an inside periphery of the main part and can abut against the electric motor. The abutting part forms a gap for blowing air between the main part and the electric motor.
