A driving apparatus and a self-brake apparatus are provided. The self-brake apparatus for use with a driving device includes a shaft, a wheel, a stopper and an elastic member. The shaft is driven by the driving device, and the wheel is movably engaged with the shaft. The stopper is positioned on the driving device. When the driving device is inactive, the elastic member provides a force pushing the wheel against the stopper to a motionless state. When the driving device is active, the shaft provides a force driving the wheel departing from the stopper to a rotation state.
