Claim Text:
1. A brake device comprising: a master cylinder that generates a brake hydraulic pressure in accordance with an operation amount of a brake operation unit by an operator; a slave cylinder that houses a hydraulic control piston operated by a driving force of an electric motor to be driven in accordance with the operation amount of the brake operation unit, and has a cylinder body formed with a brake hydraulic chamber for generating a brake hydraulic pressure through an operation of the hydraulic control piston; and a hydraulic system that connects, to the slave cylinder, a wheel cylinder for generating a braking force by the brake hydraulic pressure generated in the master cylinder or by the brake hydraulic pressure generated in the slave cylinder, wherein the cylinder body includes an air release mechanism which is configured to be switchable between an open state in which the brake hydraulic chamber is in communication with an exterior of the cylinder body and a closed state in which the brake hydraulic chamber is not in communication with the exterior of the cylinder body, wherein a reservoir for storing the brake fluid to be supplied to the brake hydraulic chamber is disposed above the air release mechanism, and wherein the reservoir has a shape with a notch over the air release mechanism.
