To provide a brake fluid pressure control device capable of improving the flexibility in design of the size of an accumulator while using a housing of a hydraulic unit in common.SOLUTION: The brake fluid pressure control device includes: a housing having an internal flow passage constituting a part of a brake fluid pressure circuit and having one end of the internal flow passage opened on an outer surface; and an accumulator unit mounted at a position where the one end of the internal flow passage of the housing is opened. The accumulator unit includes: a piston receiving a brake fluid flowing into via the internal flow passage by a surface on the one end side in an axial direction; an energizing member energizing the piston toward the one end side; and a sleeve member holding the piston in the axial direction to be reciprocated.SELECTED DRAWING: Figure 3

    【課題】液圧ユニットのハウジングを共用しつつアキュムレータのサイズの設計の自由度を向上可能なブレーキ液圧制御装置を提供する。【解決手段】ブレーキ液圧制御装置は、ブレーキ液圧回路の一部を構成する内部流路を有し、内部流路の一端が外面に開口したハウジングと、ハウジングの内部流路の一端が開口する位置に取り付けられたアキュムレータユニットとを備え、アキュムレータユニットは、軸線方向の一端側の面で内部流路を介して流入するブレーキ液を受けるピストンと、ピストンを一端側に向かって付勢する付勢部材と、ピストンを軸線方向に往復移動可能に保持するスリーブ部材とを有する。【選択図】図3
