ABSTRACT:
A fan device a frame includes a frame and a fan blade part. The fan blade part is composed of a fan hub and fan blades. The frame is provided with a driving part being rotationally attached to the fan blade part. The driving part is fixed to the frame with locating parts such that a difference of distance is formed between a facial side of the frame and the joining surface of the driving part. The fan hub is shorter than the fan blade part in height so that air current generated by the fan blades can flow fast without being stagnated under the joining surface of the driving part.
