PROBLEM TO BE SOLVED: To provide an abnormality diagnostic device which can enhance an abnormality diagnostic accuracy.SOLUTION: An abnormality diagnostic device C, which is applied for a vehicular brake device A comprising low pressure sources 171 to 173, a master cylinder 1, a drive part Y and a control part 61, comprises: a diagnostic part 62 which executes abnormality diagnosis based on at least one of a relationship between an operational amount of a brake operation member 10 and a reaction fluid pressure and a relationship between a target value and an actual value; and a judgement part 63 which judges whether a state of a reaction chamber R concerning at least one of a fluid pressure and a fluid volume is a prescribed too few state or a prescribed excess state. The diagnostic part 62 stops abnormality diagnosis when whether the state of the reaction chamber R is the prescribed too few state or the prescribed excess state is judged by the judgement part 63.SELECTED DRAWING: Figure 6

    【課題】異常診断精度を向上させることができる異常診断装置を提供する。【解決手段】本発明は、所定状況下で反力室Rと連通する低圧源171〜173と、マスタシリンダ1と、駆動部Yと、制御部61と、を備える車両用制動装置Aに適用される異常診断装置Cであって、ブレーキ操作部材10の操作量と反力液圧との関係及び目標値と実際値との関係の少なくとも一方に基づいて異常診断を行う診断部62と、液圧及び液量の少なくとも一方に関する反力室Rの状態が、所定過少状態又は所定過多状態であるか否かを判定する判定部63と、を備え、診断部62は、判定部63により反力室Rの状態が所定過少状態又は所定過多状態であることが判定されている場合、異常診断を停止する。【選択図】図6
