Abstract

A fan brake structure includes a fan and a brake device. The fan has a frame body, a fan impeller and a stator. The brake device is disposed under a bottom of a bearing cup. The brake device has a driving member, a brake member and an elastic member. The elastic member abuts against one end of the brake member. The other end of the brake member has a boss body. The driving member has a spiral rail. When the driving member rotates, the boss body moves along the spiral rail, whereby the brake member linearly reciprocally moves upward to brake the fan impeller or linearly reciprocally moves downward to release the fan impeller from the braking.
