In the above prior art, a positioning tubular body is provided to project rearward from a lower surface of the transparent cover, and a tubular portion having a positioning hole is formed in the return plate. I had to. It is impossible to provide these cylindrical bodies and cylindrical parts in a so-called combination meter, in which a plurality of windows are provided on the facing plate and a plurality of meters facing the windows are provided, due to the design of the meter device. Met. Because, referring to FIG.
A hood 5b formed on the facing plate 5
The provision of the tubular body of the transparent cover 6, the tubular portion of the return plate 5, and the like in the viewing area 8 that is visible to the driver or the like inside the interior is because the design is unsightly and reduces the value of the product.

Therefore, in order to solve the problem of design and to prevent the misalignment of the dial plate 5 and the dial 3, a tubular body which is conventionally provided on the transparent cover 6 is formed on the lower surface of the dial plate 5. In this case, it is necessary to provide the positioning tubular body in the vicinity of the display unit 7 of the dial 3, and as a result, the tubular body must be provided in a portion corresponding to the viewing area 8 of the return plate 5. However, since the return plate 5 is made of a synthetic resin, if the tubular body is formed on the lower surface of the visible region 8 of the return plate 5, there is a possibility that resin sink may occur in the visible region 8 after the formation of the return plate 5. The sink marks were not preferable in the design of the return plate 5. When there is a distance between the flat plate surface 9 of the return plate 5 and the plate surface 10 provided with the display unit 7 of the dial 3 in order to obtain a sense of depth, the distance reaches the plate surface 10 of the dial 3. Therefore, it is necessary to extend the cylindrical body so that a molding defect such as resin sink is more likely to occur.

Further, by providing the light guide with the positioning tubular body projecting in the dial plate direction, it is not necessary to form the second positioning pin projecting in the dial plate length on the dial plate. The occurrence of sink marks can be suppressed in the visual recognition area. In particular, in the case of an instrument having a distance between the plate surface of the return plate and the plate surface of the dial, a more remarkable effect can be obtained.

Further, since the second positioning pin is formed in a cylindrical shape having a hollow portion at the center thereof, it is possible to prevent sinks from being generated in the visible region of the return plate.
