Abstract

A stopping structure of a fan is described. An opening is opened on a surface of a frame, and a bearing support is disposed within the frame. A blade wheel is accommodated within the frame and pivoted to the bearing support. Then, a stopper is disposed at the frame corresponding to the opening, such that a distance between the stopper and the blade wheel is smaller than a distance between blades of the blade wheel and the frame. When the blade wheel moves outwards relative to the bearing support, the blade wheel is stopped by the stopper to prevent the blades from interfering with the frame, and a reactive force is generated at an axial center position of the blade wheel, so that an axle of the blade wheel is maintained on the same central axis as the bearing support when the axle restores an original position thereof.
