An auxiliary indicator unit 700 has an AT indicator box 750 at the center thereof for displaying a gear position. The AT indicator box 750 is made of a resin in which a light source 752 is arranged inside a cylindrical small room 751 continuously in a row, and is fixed to the printed wiring board 400 with screws 900 (see FIG. 5). The dial 730 of the auxiliary instrument unit 700 has an AT
The design corresponding to the indicator box 750 is formed, but a part of the display, for example, the display part of “1” indicating the low position and the display part of “2” indicating the second position are hardly visible at normal time and are visible only at the time of display. Different from other display parts, special printing processing such as smoke printing is performed so as to be able to be performed. Therefore, the display of the AT indicator box 750 is performed by the light of the light source 752 transmitted through the light guide 720 and the dial 730, and the light guide 72 is displayed.
By applying a predetermined coloring to 0, it is not necessary to prepare a separate color lens for each small room 751 of the AT indicator box 750, and it is possible to reduce the manufacturing cost due to the reduction in the number of parts.

This allows the specification of "1" and the specification of "2" to be commonly applicable to the same type of vehicle due to differences in grade, destination, etc., as described above. By appropriately selecting and using the wiring member 410 according to the applicable vehicle type, it is possible to share the specification depending on whether or not the specification is to display "1", thereby sharing the dial 730, the AT indicator box 750, and the like. It can be used to reduce costs. That is, in the case of the specification of displaying from "1", the light emission of "1" can be performed through the smoke by turning on the light source, and the same applies to the case of displaying "2". Also,
In the case of a specification in which “1” is not displayed but “2” is displayed, light emission of “2” can be performed through smoke by turning on the light source, and “1” is always displayed in front. I can't see it. As a result, it is possible to avoid a problem that can be considered when the present configuration is not adopted, that is, an unnecessary worry of the driver as to whether the failure is caused when the light emission display is not performed while “1” is visible. Therefore, concentration on driving operation can be promoted.

The speedometer unit 800 is provided with a distance display unit 850 for displaying a travel distance and an arbitrary section distance at a lower portion. In the distance display unit 850, a liquid crystal panel 852 is accommodated in a cylindrical case 851 made of resin.

The display can be appropriately switched by the operation of 41, and this display is displayed from the window 832 provided on the dial 830.

Illumination members will be described with reference to FIG. 11. Illumination at night of the instrument 100 for vehicles, illumination at day and night of the distance display unit 850, and selective display in the AT indicator box box 750 include the printed wiring board 40.
0, a plurality of small lamps 430 as lighting members mounted by bayonet coupling.
30 has a different wattage depending on the purpose of use. Generally, a large wattage is used for the illumination, and a small wattage is used for the display as compared with the illumination. However, the wattage of the lamp 430 is different only by changing the filament of the bulb, and the appearance is hard to distinguish. Therefore, when a plurality of lamps 430 having different wattages are arranged close to each other,
The lamps 430 having the same wattage are arranged in an easily understandable manner, for example, in a linear arrangement, and are arranged so as to be easily distinguished from the lamps 431 having different wattages. Thereby, the lamps 430 to be attached,
The risk of mistaking 431 is reduced, which is convenient for manufacturing.

In such a configuration, the liquid crystal display unit 600 provides, for example, navigation information for displaying the current position and the destination on a map based on a signal from a GPS device or a broadcast receiving device (neither is shown) provided in the vehicle. Alternatively, in addition to displaying information related to vehicle travel such as road traffic information transmitted by a radio signal, a signal from a video camera can display information unrelated to vehicle travel. A visual jack (AV terminal) 440 is provided. The AV terminal 440 is pulled out below the front end of the visor 300, which is the front side of the vehicle instrument device 100, and is arranged close to an AV selector (not shown) which is a switch for switching display contents on the liquid crystal display unit 600. The AV selector switches an input signal by operating a push switch. The AV selector is configured to output a predetermined output signal by both the rotation operation and the push operation of the illuminator knob 642 and the volume operated by the illuminator knob.
The selector can be used also as the illumination knob 642.
Therefore, by installing the AV terminal 440 near the illuminated knob 642, the connection of the AV terminal 440 and the switching of the AV selector can be easily performed, which is convenient. Cost can be reduced.

Of course, when the AV selector is set to the trip knob 641
Although the trip knob 641 generally switches the display by a push operation, the trip knob 641 is also used as an AV selector that switches an input signal by a similar push operation. In this case, there is a risk of erroneous operation, and it is more desirable to use the same as the illuminator knob 642 which is operated by a rotation operation different from that of the AV selector.
