In the present invention, a base is reduced in size despite the presence of a caliper pressure sensor. An inlet port and an outlet port are disposed in the top part of a base (100); a reservoir (5) is disposed in the bottom part of the base; a pair of pumps (6) are disposed between the inlet port and the reservoir; a pressure booster valve, a depressurizing valve, a cut valve, and a caliper pressure sensor are disposed in a row in a direction along the center axis of each pump; the pressure booster valve is disposed above the center axis (Y1) of the pump; the depressurizing valve is disposed below the center axis of the pump; the cut valve is disposed between the pressure booster valve and the depressurizing valve and is also disposed nearer the middle of the base than the pressure booster valve and the depressurizing valve disposed at the end of the base; and a suction valve (4) is disposed between the depressurizing valves that, of the depressurizing valves aligned in the direction along the center axes of the pumps, are aligned nearer the end of the base than a vertical reference line passing through the rotational center axes of the pumps. The suction valve communicates with a pair of cut valves, and a master pressure sensor (8) is disposed on the reference line of the base. |
