Further, the illumination means 3 uses light sources of different emission colors, and in this case, blue and white are prepared, and the pointer 4 and the display board 5 can be selectively illuminated.

  The control means 1, the drive means 2, and the illumination means 3 are mounted on a circuit board P provided on the back side of the display board 5, and the pointer 4 is provided to be rotatable in the surface direction on the surface side of the display board 5. It is done. Further, the display board 5 is subjected to a printing process so that a predetermined pattern of the indicator portion 51 is formed on the light-transmitting substrate. The indicator 51 has a shape that allows the measurement value to be read by contrast using the pointer 4 with scales, numbers, characters, and the like. In this case, a scale indicating the engine speed and a display indicating the unit, and a scale corresponding to the instantaneous fuel consumption value and a display indicating the unit are shown.

  Next, the control process by the control means 1 regarding this invention is demonstrated.

  The control means 1 monitors the operation state of the switch for switching the vehicle travel mode described above, and determines the mode based on the signal (predetermined signal) from the switch to determine which mode is the current setting state. In this case, a low fuel consumption mode and a sports mode are provided as vehicle driving modes, and the characteristics in engine control can be switched.

  Next, the control means 1 calculates the instantaneous fuel consumption value based on the input vehicle information and indicates the calculated instantaneous fuel consumption value when the currently set state is in the low fuel consumption mode based on the mode determination. Thus, the driving means 2 is controlled.
