The liquid chambers are arranged in the axial direction, and a hydraulic pressure control valve is integrally provided in the cylinder body for controlling the hydraulic pressure supplied to the rear wheel cylinder by the operation of a control piston when the hydraulic pressure increases. In the master cylinder provided, the two systems of hydraulic pressure control valves are respectively arranged in parallel to the cylinder body with respect to the arrangement direction of the master cylinder liquid chambers. (2) The master cylinder according to item 1, wherein the hydraulic pressure control valves are arranged in opposite directions to each other within the cylinder body. (3) The master cylinder according to item 1, wherein master hydraulic pressures of other systems are respectively applied to the rear of the piston holding a poppet valve element for opening and closing the internal flow path of the control piston of the hydraulic pressure control valve. .
