MOTOR, METHOD FOR MANUFACTURING THE SAME AND BLOWING FAN

PROBLEM TO BE SOLVED: To provide a motor in which rotational torque does not decrease even if a size of a bearing part is enlarged and a bearing housing is made strong and to provide a blowing fan whose air volume does not drop. SOLUTION: The motor includes the bearing part 5 supporting a rotor 2 so that it rotates with a rotation shaft J as a center, the bearing housing 4 in an almost cylindrical shape, which supports the bearing part 5, and a stator 3 supported by the bearing housing 4. The bearing housing 4 has small diameter parts 42a and 42b which are arranged in a center with respect to an axial direction and whose outer diameters are small, and large diameter parts 41a and 41b which are separately installed in the axial direction across the small diameter parts 42a and 42b. An inner peripheral face of the stator 3 abuts on outer peripheral faces of the small diameter parts 42a and 42b. The bearing part 5 abuts on inner peripheral faces of the large diameter parts 41a and 41b. The bearing housing 4 is divided in the axial direction in the small diameter parts 42a and 42b.
