Abstract
The invention concerns a structure for mounting a fan to a fan motor. The structure is designed to fit a plurality of thrust washers onto the end of a motor shaft supported in a casing through a bearing and to thrust and fit a flat washer on a peripheral surface of a smaller diameter step formed on the tip side further than the washers-fitted section. Of these thrust washers, the most outer, tip side, thrust washer located opposite to the flat washer is thicker than the traveling play distance toward the core of a motor shaft and thinner than the interval from the adjacent thrust washer to the peripheral surface of the step. With the construction, hence, the invention serves to prevent the thrust washer from falling onto the smaller diameter step.
