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. The check valve includes a valve body that comes in contact with a sheet part provided at an opening end of the second circulation hole, and a leaf spring fixed to the base part for energizing the valve body to the sheet part.SELECTED DRAWING: Figure 3

    【課題】アキュムレータと逆止弁とを一体化してハウジングへの組付工程を減らすことができ、かつ、液圧ユニットのサイズを小型化することが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、ハウジングの第1の内部流路及び第2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を備え、アキュムレータユニットは、第1の流通孔及び第2の流通孔を有しハウジングに固定される基部と、基部に固定されるスリーブ部材と、スリーブ部材の内部に軸線方向に往復移動可能に保持され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、逆止弁とを備え、逆止弁は、第2の流通孔の開口端に設けられたシート部に当接する弁体と、基部に固定され、弁体をシート部に向けて付勢する板ばねとを有する。【選択図】図3
