Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vehicle hydraulic device with battery degradation determination capable of avoiding a situation where a vehicle is unable to travel due to degradation of a battery by determining the battery degradation on the hydraulic device side and notifying an operator.SOLUTION: A vehicle hydraulic device with battery degradation determination comprises: a voltage measurement device 20 for measuring an input voltage from a battery BT; a controller 10 having a calculation function and a storage function; and notification means such as an LED 30 for notifying an operator of battery degradation. The controller 10 detects a voltage difference between pre-operation and in-operation of the hydraulic device (an electric motor) measured by the voltage measurement device 20. The controller determines battery degradation when the voltage difference becomes a prescribed threshold value or more, and drives the notification means such as the LED 30.SELECTED DRAWING: Figure 1 【課題】油圧装置側でバッテリの劣化を判断して作業者に知らせることで、バッテリの劣化に伴う車輌の走行不能を回避可能なバッテリ劣化判断付き車輌用油圧装置を提供する。【解決手段】バッテリＢＴからの入力電圧を計測する電圧計測装置２０と、演算機能及び記憶機能を有するコントローラ１０と、バッテリ劣化を報知するＬＥＤ３０等の報知手段とを備え、電圧計測装置２０で計測された油圧装置（電動機）作動前と作動中の電圧差をコントローラ１０で検知し、コントローラは前記電圧差があらかじめ設定した所定閾値以上になったときにバッテリ劣化と判断してＬＥＤ３０等の報知手段を駆動する。【選択図】図１
