<p>The purpose is to decrease the physical size of a brake fluid pressure control apparatus for implementing pressure increasing/decreasing control for the fluid pressure in a wheel cylinder. A brake fluid pressure control apparatus is provided with: a piston pump (5); a pump drive motor (3); an eccentric cam rotated by the motor to activate the piston pump; a pressure-increasing electromagnetic valve (6); and a pressure-decreasing electromagnetic valve (7), in which the piston pump (5), the eccentric cam, the pressure-increasing electromagnetic valve (6), and the pressure-decreasing electromagnetic valve (7) are assembled in a housing (1a). The single piston pump (5) is installed, with the piston pump (5), when mounted on a vehicle, disposed in an upright posture under or above a cam chamber (11) of the housing in which the eccentric cam is housed.</p> |
