Abstract
An electric brake device includes an electric motor, a braking force application mechanism, a lock mechanism, a temperature sensor for measuring an ambient temperature of a vehicle in which the electric brake device is provided, and a freezing preventive power supply unit. The freezing preventive power supply unit initiates the supply of an electric power to the electric motor or a drive source of the lock mechanism in the event that while the braking force application mechanism applies a braking force and the lock mechanism is held in a locked condition, the temperature sensor detects a preset temperature of the electric brake device immediately before freezing.
