Abstract:
To provide a brake fluid pressure control device that allows steps to integrate an accumulator and a check valve for assembling to a housing to be reduced, and allows the size of a hydraulic pressure unit to be reduced.SOLUTION: A brake fluid pressure control device includes an accumulator unit attached to a location where one end of a first internal flow passage and a second internal flow passage of a housing opens. The accumulator unit includes a base part having a first circulation hole and a second circulation hole, which is fixed to the housing, a sleeve member fixed to the base part, a piston held inside the sleeve member so as to reciprocate in an axial direction for receiving brake fluid, an energizing member for energizing the piston to one end side, and a check valve.
