ブレーキ装置。[Scope of Claim for Utility Model Registration] A master cylinder that generates brake fluid pressure in response to the operation of a brake operating member, a brake cylinder that operates a brake that suppresses wheel rotation, and a brake fluid pressure that is generated in the mass cylinder. There is a main fluid passage leading to the cylinder, and a pressure increase permissible state in which the brake cylinder is communicated with the mask cylinder to allow the brake cylinder fluid pressure to rise, and a pressure increase permissible state in which the brake cylinder fluid pressure is allowed to increase by communicating with the brake cylinder and the brake cylinder is in communication with the reservoir. an electromagnetic control valve capable of switching to a pressure drop permissible state that allows a decrease in cylinder fluid pressure; , a pump that supplies a portion of the main liquid passageway between the mask cylinder and the electromagnetic control valve; and a brake that is supplied from the pump to the main liquid passageway at least while the controller is controlling the electromagnetic control valve. A backflow prevention device for preventing liquid from flowing back toward the mask cylinder side, an anti-skid type hydraulic brake device for an automobile including a backflow prevention device that prevents liquid from flowing back to the side of the mask cylinder. The inner space is partitioned into a first liquid chamber and a second liquid chamber, the piston is urged toward the first liquid chamber by an elastic member, and the first liquid chamber is used to prevent backflow in the main liquid passage. A hydraulic brake device, characterized in that the second liquid chamber is connected to a portion between the device and the electromagnetic control valve or to the pump passage, and the second liquid chamber is connected to the mask cylinder.
