PROBLEM TO BE SOLVED: To improve the mounting structure of the impeller of a blower. SOLUTION: In a blower where an impeller 8, a motor yoke 11, etc., are attached to the shaft 6 supported by bearings 4 and 5, and also a stator iron core 16 is arranged inside the motor yoke 11, an indent 19 is provided at one end of the shaft 6 having uniform diametrical dimensions, and the center of the motor yoke 11 made in cup form is calked to the section of this indent 19. A boss made by die cast of zinc, which was necessary in the past becomes needless, so the structure becomes simple, and the mounting is secured.
