ようになっている。Fig. 1 is a sectional view showing an embodiment of the present invention, and Fig. 2 is a perspective view showing half of the boss portion of the blade with the rotating shaft removed. (11) shows the boss part (8a) on the inner surface of the boss part (8a).
(12) is a pedestal that is linearly connected to this boss rib and projects from the bottom of the boss rib. A rotor yoke (9) having a ring-shaped cross section is provided on the upper surface of the pedestal and the tip of the boss rib, and the end of the pedestal (12) is provided between the rotor yoke (9) and the inner peripheral side wall of the boss portion (8a). A ventilation path (13) is formed from the part to the end of the boss rib (11). (14) is a recess provided in the center of the boss part (8a) of the wing, and a hole (15) into which the rotating shaft (7) is fitted is formed in the center. The fixing surface (8C), which is the side wall to which the rotating shaft ■ is fixed, has five convex portions (i6
) is provided. <1? ) is a metal reinforcing member provided with a fitting hole (18) that fits into this convex part (16),
A through hole (18) through which the rotating shaft (7) passes is provided at the center, and a plurality of caulking holes (20) are provided around this through hole. (21) is a force-retaining member made of brass that is caulked and fixed to this reinforcing member by a caulking piece (22) that is inserted through a caulking hole, and a shaft hole (23) into which the rotating shaft (7) is fitted is provided in the center. Note that the blade (a), reinforcing member (17), holding member (21), and rotation/shaft (7) are secured by caulking the reinforcing member (17) and holding member (21) together, and caulking the piece (22). It is inserted into the hole (21) and fixed by caulking, and the rotating shaft ■ is fitted into the shaft hole (23).Next, the fitting hole (18) of the reinforcing member (17) is inserted into the blade (to). At the same time as fitting into the convex part (16), the rotating shaft (7) is fitted into the hole (15) of the blade, and by applying ultrasonic vibration, the synthetic resin blade side melts and the fitting is completed. The mating side will be welded and fixed. At this time, the caulking piece (
22) is prevented from hitting by the recess (14).

くなり変形することがない。On the other hand, air is drawn from outside the blade into the boss portion (8a) through the gap between the stator (4) and the rotor magnet while cooling the stator G41. At this time, the pedestal (12
), the boss rib (11) has the function of a blowing blade, increasing the amount of air blown and increasing the cooling effect. A blower that blows air in this way is used for cooling electronic equipment, etc., but when blowing air, it receives heat from the electronic equipment, and the temperature of the blade (81) rises due to the heat generated by the electronic equipment itself, and the temperature of the blade (81) increases. Since it is made of resin, it softens, but a reinforcing member (17) is provided along the fixed surface (8C) of the blade (5), and the rotating shaft (7) is fitted onto this reinforcing member (17). Since the holding member (21) is provided, the strength is increased and there is no possibility of deformation.
