To provide a vehicular braking device that can suppress contact of an input piston with a master piston without being enlarged in size and exert appropriate braking performance.SOLUTION: The vehicular braking device comprises: an input piston 13 that advances in a predetermined direction in a cylinder 11 in accordance with increase in stroke of a brake operation member 10; a master piston 14 arranged in the cylinder 11 separately in a predetermined direction from the input piston 13; a driving part 4 that drives the master piston 14 in a predetermined direction to generate master pressure; and a regenerative braking part 8 that imparts regenerative braking force to a wheel, which cooperatively controls the regenerative braking part 8 and the driving part 4 while increasing regenerative braking force according to increase in stroke. The device further comprises a control part 61 that when the stroke is equal to a predetermined value or more, executes adjustment control so that amounts of driving of the master piston 14 by the driving part 4 is increased by a specified value and regenerative braking force is decreased corresponding to the specified value.SELECTED DRAWING: Figure 3

    【課題】装置を大型化させることなく入力ピストンとマスタピストンとの当接を抑制でき、且つ適切な制動性能を発揮することができる車両用制動装置を提供する。【解決手段】本発明は、ブレーキ操作部材10のストロークの増大に応じてシリンダ11内を所定方向に進行する入力ピストン13と、シリンダ11内において入力ピストン13に対して所定方向に離間して配置されたマスタピストン14と、マスタピストン14を所定方向に駆動することでマスタ圧を発生させる駆動部4と、車輪に回生制動力を付与する回生制動部8と、を備え、ストロークの増大に応じて回生制動力を増大させつつ、回生制動部8と駆動部4とを協調制御する車両用制動装置であって、ストロークが所定値以上になった場合、駆動部4によるマスタピストン14の駆動量を規定値増大させ且つ規定値に応じて回生制動力を減少させる調整制御を実行する制御部61を備える。【選択図】図3
