Abstract
A braking structure for fan includes a fan and a braking device connected to the fan. The braking device includes a first braking mechanism, a second braking mechanism and a support seat. The first braking mechanism is connected to a free end of a shaft of the fan, the second braking mechanism is fitted in the support seat, and the support seat is engaged with a bottom of a frame of the fan. When the fan is turned off, the braking device is no longer energized, bring the first and the second braking mechanism to engage with each other and accordingly produce a braking effect, so that the fan can more quickly stop rotating.
