<p>PROBLEM TO BE SOLVED: To achieve downsizing of physical constitution of a brake fluid pressure control device for controlling increase and decrease of fluid pressure of a wheel cylinder.SOLUTION: A brake fluid pressure control device comprises: a piston pump 5; a motor 3 for driving the pump and an eccentric cam for actuating the piston pump by rotating the piston pump with the motor; an electromagnetic valve 6 for increasing pressure; and an electromagnetic valve 7 for decreasing pressure. The piston pump 5, the eccentric cam, the electromagnetic valve 6 for increasing pressure, and the electromagnetic valve 7 for decreasing pressure are incorporated in a housing 1a. Only one piston pump 5 is installed in the housing 1a, and the piston pump 5 is disposed in a standing posture below or above a cam chamber 11 of the housing storing the eccentric cam, while the piston pump 5 is in a device installation state to a vehicle.</p> |
