PROBLEM TO BE SOLVED: To provide a vehicular braking device that can improve durability of a valve portion while suppressing deterioration in accuracy of traction control.SOLUTION: The vehicular braking device comprises: a fluid pressure control portion 171 which, when an actual pressure which is an actual value of driving fluid pressure is a value out of a dead zone, controls a valve portion 15 so that the actual pressure approaches a target pressure and, when the actual pressure is a value within the dead zone, controls the valve portion 15 so that the actual pressure is retained; an actuator 16, provided in fluid pressure paths 22, 24, 40a and 50a through which master chambers R1 and R2 are connected to a wheel cylinder WC, which adjusts flowing-out of fluid from the master chambers R1 and R2 to the wheel cylinder WC; a traction control portion 173 which executes traction control in which slippage of a vehicle when accelerating the vehicle is suppressed by controlling the actuator 16; and a dead zone setting portion 174 which widens a width of the dead zone according to a control state of the traction control.SELECTED DRAWING: Figure 2

    【課題】トラクション制御の精度低下を抑制しつつ弁部の耐久性向上を図ることができる車両用制動装置を提供する。【解決手段】本発明の車両用制動装置は、駆動液圧の実際値である実圧が不感帯外の値である場合に、実圧を目標圧に近づけるように弁部15を制御し、実圧が不感帯内の値である場合に、実圧を保持するように弁部15を制御する液圧制御部171と、マスタ室R1、R2とホイールシリンダWCとを接続する液圧路22、24、40a、50aに設けられ、マスタ室R1、R2からホイールシリンダWCへのフルードの流出を調整するアクチュエータ16と、アクチュエータ16の制御により車両の加速時のスリップを抑制するトラクション制御を実行するトラクション制御部173と、トラクション制御の制御状態に応じて、不感帯の幅を拡げる不感帯設定部174と、を備える。【選択図】図2
