PROBLEM TO BE SOLVED: To provide a structure of a radiator which is manufactured into a comparatively small size, and wherein working and manufacturing are easy, and relatively higher rotation torque can be obtained by generating a repulsive force which repulses directly a permanent magnet having NS poles by a magnetic force generated from a coil. SOLUTION: A penetrating hole is bored on a base, a wind entering port and a wind discharging port are formed at both ends of the penetrating hole, and a retaining part is arranged at one end of the penetrating hole. At least two coils are combined with the base, an IC control element is arranged on the base, and electrically continuous contact is allowed between the IC control element and the coils. A rotating shaft and a plurality of blades are formed on a rotor. A permanent magnet is arranged annularly on the outer periphery of the blade, and one end of the rotating shaft is pivotally attached to a retaining part of the base. Since magnetic forces which are repulsed directly can be generated between the permanent magnet and the coils of the base, a constitution is so performed that the rotor can be driven and rotated.
