Brake fluid pressure control device

A brake hydraulic pressure controller (10) for a four-wheeled motor vehicle and for controlling a hydraulic pressure in a brake hydraulic circuit, the brake hydraulic pressure controller (10) comprising:

• a housing (110);
• a motor (96) mounted on a first surface (110a) of the housing (110);
• and
• plural electromagnetic control valves (34a, 34b, 46a, 36b, 54aa, 54ba, 54ab, 54bb, 58aa, 58ba, 58ab, 58bb) mounted on a second surface (110b) that opposes the first surface (110a) of the housing (110), wherein
• the plural electromagnetic control valves (34a, 34b, 36a, 36b, 54aa, 54ba, 54ab, 54bb, 58aa, 58ba, 58ab, 58bb) are arranged in plural rows (L1, L2, L3) from a near side to a far side from a third surface (110c) that continues perpendicularly from both of the first surface (110a) and the second surface (110b), and
• the plural electromagnetic control valves include two circuit control valves (36a, 36b) and four booster regulators (58aa, 58ba, 58ab, 58bb), which are arranged in the same row, the two circuit control valves (36a, 36b) being arranged in channels (33a, 33b) that connect piping ports (121a, 121b), to which piping connected to a master cylinder is connected, and discharge sides of pumps (44a, 44b) driven by the motor (96), and the four booster regulators (58aa, 58ba, 58ab, 58bb) being arranged in channels (51aa, 51ba, 5 lab, 51bb) that connect the circuit control valves (36a, 36b) and piping ports (123a, 123b, 123c, 123d), to which piping connected to wheel cylinders is connected.
