Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a measuring instrument for a vehicle which achieves space saving and yet is able to supply electric power to an external device.SOLUTION: A measuring instrument for a vehicle includes: a liquid-crystal display panel which utilizes electric power from an on-vehicle battery B to display vehicle information; an overvoltage protection circuit 4 provided between the on-vehicle battery B and the liquid-crystal display panel; and a DC/AC conversion circuit 9 which utilizes electric power of the on-vehicle battery B, which is supplied through the overvoltage protection circuit 4, to supply electric power to an external device D. The measuring instrument for the vehicle includes these components in the same case.SELECTED DRAWING: Figure 1 【課題】省スペースであっても外部機器へ給電できる車両用計器を提供する。【解決手段】車載バッテリＢからの電力を利用して車両情報を表示する液晶表示パネルと、車載バッテリＢと液晶表示パネルとの間に設けられる過電圧保護回路４と、この過電圧保護回路４を介して供給される車載バッテリＢの電力を利用して外部機器Ｄへの給電を行うＤＣ／ＡＣ変換回路９と、を同じケース内に備える。【選択図】図１
