To provide a vehicular brake fluid pressure control device which can control a biasing force of a piston acting on the fluid pressure chamber side of an accumulator.SOLUTION: An accumulator of a vehicular brake fluid pressure control device includes: a bottomed cylinder hole (120) which is formed at a base (51) of the vehicular brake fluid pressure control device and in which a communication passage of a blake fluid opens; a plug (130) which closes an opening of the cylinder hole (120); a piston (110) which is provided in the cylinder hole (120) so as to be movable in an axial direction (120a) of the cylinder hole (120) and partitions the cylinder hole (120) into a communication passage side fluid pressure chamber and a plug side gas chamber; a magnetic material (115) which is disposed in the piston (110) and may move with the piston (110); a coil (135) which is disposed in a space formed between the cylinder hole (120) and the plug (130) and is energized to generate a magnetic field; and a power supply part (136) which is connected to the coil (135) and supplies electric current to the coil (135).SELECTED DRAWING: Figure 2

    【課題】アキュムレータの液圧室側に作用するピストンの付勢力を自在に制御することが可能な、車両用ブレーキ液圧制御装置の提供。【解決手段】車両用ブレーキ液圧制御装置の基体(51)に形成され、ブレーキ液の連通路が開口する有底のシリンダ穴(120)と、シリンダ穴(120)の開口を塞ぐプラグ(130)と、シリンダ穴(120)内にその軸方向(120a)に移動可能に設けられるとともにシリンダ穴(120)を連通路側の液圧室とプラグ側の気体室とに区画するピストン(110)と、ピストン(110)に配置され、ピストン(110)と共に移動可能な磁性体(115)と、シリンダ穴(120)とプラグ(130)とにより形成される空間に配置され、通電することにより磁界を発生させるコイル(135)と、コイル(135)と接続され、コイル(135)に電流を供給する給電部(136)と、を備える。【選択図】図2
