PROBLEM TO BE SOLVED: To provide a vehicle meter gauge which alerts a battery reversed connection state.SOLUTION: A vehicle meter gauge A includes a horn drive circuit 4 which drives a horn E provided between electrodes of a battery B. The vehicle meter gauge A includes control means 3 which controls the horn drive circuit 4 on the basis of operation conducted by a vehicle user. The horn drive circuit 4 is provided with an FET. A drain 4d is connected with the positive electrode side of the battery B and a source 4s is connected with the negative electrode side of the battery B through the horn E. A gate 4g for switching the energization state from the drain 4d to the source 4s is connected with the control means 3.SELECTED DRAWING: Figure 3

    【課題】 バッテリ逆接続状態について警報できる車両用計器を提供する。【解決手段】 バッテリBの両電極間に設けられるホーンEを駆動するホーン駆動回路4を備える車両用計器Aにおいて、車両利用者による操作に基づいてホーン駆動回路4を制御する制御手段3を備え、ホーン駆動回路4は、FETを設け、ドレイン4dをバッテリBのプラス電極側に接続し、ソース4sをホーンEを介してバッテリBのマイナス電極側に接続し、ドレイン4dからソース4sへの通電状態を切り替えるためのゲート4gを制御手段3に接続する。【選択図】 図3
