PROBLEM TO BE SOLVED: To provide a vehicle instrument which reduces possibilities to cause malfunctions of a built-in electric circuit.SOLUTION: A vehicle instrument M according to the present invention comprises: a display 1 for displaying an image; a dial face 2 located on a front surface of the display 1; a conductive decorative member 4 which is located on and in contact with the dial face 2; and a circuit board 5 located on a back surface of the display 1. The decorative member 4 includes an extension part 41 that is in contact with a ground part 54 of the circuit board 5. This configuration electrically connects the decorative member 4 and the ground part 54 of the circuit board 5, resulting in achieving an effect of reduction in noises occurring from the decorative member 4. The contact between the decorative member 4 and the dial face 2 allows static electricity occurring on the dial face 2 to flow to the circuit board 5, resulting in reducing possibilities of adhesion of dust due to charging of the dial face 2.SELECTED DRAWING: Figure 2
【課題】 内蔵された電気回路の誤動作を招く虞を低減する車両用計器を提供する。【解決手段】 本発明に係る車両用計器Mは、画像を表示する表示器1と、表示器1の前面に配置される文字板2と、文字板2上に当接して配設される導電性の加飾部材4と、表示器1の背面側に配設される回路基板5と、を備え、加飾部材4は、回路基板5のグランド部54に当接する延在部41を有する。このように構成することで、加飾部材4と回路基板5のグランド部54とが電気的に接続するため、加飾部材4から発生するノイズの低減効果が得られる。また、この加飾部材4は文字板2とも当接するため、文字板2に発生する静電気を回路基板5に流す効果が得られ、文字板2が帯電してゴミが付着する虞も低減できる。【選択図】 図2
