Abstract:
Provided is a brake device that can increase energy efficiency. The present invention is provided with: a master cylinder (5) that generates fluid pressure alongside the operation of a brake by a driver; and a booster device that reduces the force of operation of the brake by the driver by means of an energy source (fluid pressure unit (6)). In a predetermined brake operation region, the operation of the booster device is suppressed.
