Zusammenfassung:PROBLEM TO BE SOLVED: To provide a motor support structure capable of reducing magnetic sounds generated from a motor.SOLUTION: A press-fit part 121b of a motor holder 12 has high rigidity in a radial direction, and a yoke 102 of a motor 10 is press-fitted with the press-fit part 121b. Therefore, vibration of the yoke 102 generating magnetic sounds is restrained by the rigidity in the radial direction of the press-fit part 121b. Also, a yoke insertion part 121 of the motor holder 12 has a gap part 121c other than the press-fit part 121b, and the gap part 121c forms a radial gap across an entire circumference of the yoke 102. Therefore, it is difficult to transmit the vibration of the yoke 102 to the gap part 121, and the magnetic sounds from the yoke 102 can be restrained from being transmitted to the motor holder 12 and an air-conditioning case that are members around the yoke 102. Accordingly, the press-fit part 121b and the gap part 121c are provided, and therefore, the magnetic force can be reduced. 【課題】モータから発する磁気音の低減を図ることができるモータ支持構造を提供する。【解決手段】モータホルダ12において圧入部121bは径方向剛性が高く、モータ10のヨーク102はその圧入部121bに圧入されているので、磁気音を発生させるヨーク102の振動が圧入部121bの径方向剛性によって抑えられる。それと共に、モータホルダ12のヨーク挿入部121は圧入部121bの他に隙間部121cを有し、その隙間部121cはヨーク102に対して径方向隙間をそのヨーク102全周にわたって形成しているので、ヨーク102の振動が隙間部121へ伝わり難く、その分、ヨーク102からの磁気音がそのヨーク102周りの部材であるモータホルダ12及び空調ケースへ伝わることを抑制できる。従って、圧入部121bと隙間部121cとを設けることによって磁気音の低減を図ることができる。【選択図】図1
