キ装置。[Scope of Claim for Utility Model Registration] An acceleration sensor that detects vehicle body acceleration in the longitudinal direction of the vehicle body, and an abnormality detection means that detects an abnormality of the acceleration sensor, and calculates an estimated vehicle speed based on the vehicle body acceleration, and calculates the estimated vehicle speed based on the vehicle body acceleration. The brake fluid pressure is increased or decreased to keep the slip rate of the wheel determined from the estimated vehicle speed and the wheel speed of the controlled wheel within a predetermined range, and when an abnormality in the acceleration sensor is detected, the brake fluid pressure is In an anti-skid brake device that operates the acceleration sensor to an increasing side, the holding means holds the vehicle body acceleration detected by the acceleration sensor for a predetermined period of time, and when an abnormality occurs in the acceleration sensor, the abnormality occurrence is held by the holding means. An anti-skid brake device comprising: signal output means for outputting a variable periodic signal that increases brake fluid pressure in stages according to the magnitude of vehicle acceleration in front of the vehicle.
