<P>PROBLEM TO BE SOLVED: To achieve both securing fixing strength between an impeller and a ring magnet and reducing costs. <P>SOLUTION: In a blower motor 10, a stopper part 54 supporting a ring magnet 46 from the other side in an axial direction, a control part 56 controlling the position of the ring magnet 46 from the outside in a radial direction, and a holding part 58 holding the ring magnet 46 so as to make the ring magnet 46 immobile to one side in the axial direction are formed in a body part 48 of an impeller 44. Because of this configuration, a fixing strength between the impeller 44 and the ring magnet 46 can be secured by the stopper part 54, the control part 56, and the holding part 58. Furthermore, a reduction in cost is possible because it is unnecessary to bond or press-fit the ring magnet 46 to the body part 48. <P>COPYRIGHT: (C)2012,JPO&INPIT |
