摘要： An anti-skid device for use in a vehicle hydraulic brake system comprising a hydraulic pressure generating device for generating hydraulic pressure in response to actuation of a brake pedal, a brake cylinder for receiving the hydraulic pressure from the hydraulic pressure generating device and for applying brake force to a wheel of the vehicle, a passage through which the hydraulic pressure is adapted to be transmitted from the hydraulic pressure generating device to the brake cylinder, lock detecting device for detecting that a wheel is locked and a damping valve designed to function to interrupt the transmission of the hydraulic pressure from the hydraulic pressure generating device to the brake cylinder and to further reduce the pressure in the brake cylinder when the lock detecting mechanism detects that wheel is locked so that the wheel-lock may be released. The damping valve comprises a plunger movable such as to open and close a valve seat and a diaphragm for movably supporting the plunger and for liquid-tightly sealing a valve chamber defined around the valve seat. The plunger is integrated with the diaphragm by bonding and is provided at one end thereof with a valve body having a spherical surface portion for contacting the valve seat.
