Zusammenfassung:	An adjustable and stable pre-loading device equipped fan includes a stator, a first rigid spacer, a first bearing, an elastic device, a second bearing, a second rigid spacer a rotor and a shift. Among these, the stator includes a receptacle. The first bearing is formed on the first rigid spacer in the receptacle. The elastic device is formed in the receptacle and further on the first bearing. The second rigid spacer is formed on the second bearing on the elastic device. The rotor is coupled to the stator and has a blade structure. The first rigid space compresses the elastic device by means of the first bearing. The second rigid space compresses the elastic device by means of the second bearing. The distance between the first rigid spacer and the second rigid spacer is adjustable, thereby altering pre-loading applied on the first bearing and the second bearing.
