The present invention relates to a fixing structure of motor spindle, which includes a spindle and a snap ring. One end of the spindle has a snap slot with a reduced diameter, and the inner hole of the snap ring shall be slightly greater than the maximum outer diameter of the snap slot, thereby maintaining a gap with a radius difference between the inner hole of the snap ring and the snap slot of the spindle in size of less than or equivalent to 0.37 mm. Meanwhile, by means of the holding effect of a bearing and a bottom cap, the snap ring of the present invention won't rotate with the spindle and won't generate noise due to abrasion with the spindle. Not only can the snap ring stably hold and fix the spindle to prevent the spindle from disengaging, but also it is free of the noise issue out of abrasion.
