液圧ブレーキ装置。[Scope of Claim for Utility Model Registration] A hydraulic pressure source and brake cylinders of brakes provided on the front and rear wheels are connected by a fluid passage,
A hydraulic brake system that suppresses rotation of the front and rear wheels by hydraulic pressure supplied from a hydraulic pressure source to a brake cylinder, and a rear liquid passage provided in a rear liquid passage connecting the hydraulic pressure source and a rear brake cylinder of the rear wheel. , a proportioning valve that reduces the hydraulic pressure supplied to the rear brake cylinder at a fixed ratio, and an anti-skid device that automatically controls the hydraulic pressure of the brake cylinder to keep wheel slip within an appropriate range. In the brake device, a bypass passage that bypasses the proportioning valve is provided in the rear fluid passage, and an electromagnetic on-off valve is provided in the bypass passage, and
an abnormality detection means for detecting an abnormality in the anti-skid device; and normally the electromagnetic on-off valve is in an open state;
A hydraulic brake device comprising: switching means for switching to a closed state based on abnormality detection by the abnormality detection means.
