Abstract: A ceiling fan includes a motor and plural blades. The motor has its topside and underside respectively secured with a fixed seat, which has its inner side formed with two protruding edges spaced apart and respectively having a pressing plate fixed thereon. The pressing plates are correspondingly combined with the fixed seats so that the blades can be firmly combined with the fixed seats via the pressing plates. The pressing plates can easily be processed and made by small-sized forming molds, able to lower manufacturing cost, and the blades of this invention can be secured on the motor quickly and stably and driven to rotate smoothly and steadily. Further, during assembly of the blades, fine adjustment can be done to respective assembly structure for overcoming errors caused by tolerance. To sum up, this invention is able to shorten man-hour in assembly, enhance assembly efficiency and increase economic gains.
