[Problems to be solved by the invention]

However, in the conventional instrument dial positioning structure, since the guide pins are formed by integral molding with the case 1, misalignment is likely to occur, and the dial 3b and the warning lens 9 of the fuel gauge 3 are respectively provided. Since it is positioned with respect to the case 1 by a pair of separate guide pins, a relative displacement occurs, and the pattern 9a of the warning lens 9 in the opening window 3c of the dial 3b is displaced or tilted from a desired center position. There is a problem that it is difficult to see.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems, and in a state where the dial and the warning lens are positioned in the case, the pattern of the instrument dial is arranged at a predetermined position with respect to the opening window of the dial. It is an object to provide a positioning structure.

[Means for solving the problem]

In order to solve the above-described problems, the instrument dial positioning structure according to the present invention has a warning lens provided with a simple pattern indicating a warning content for displaying a warning, and a warning lens disposed on an upper surface of the warning lens. A dial having an opening window for displaying a warning display by the warning lens, a dial for displaying a measured amount in cooperation with a pointer, is protrudingly provided in a round hole and a long hole formed in these, respectively, in a case. In the positioning structure of the instrument dial for positioning the relative position to the case by fitting the guide pin, a round hole and a long hole of the dial are formed on both sides of the opening window with the opening window interposed therebetween, and the warning lens of the warning lens is formed. A round hole and a long hole are formed at positions respectively corresponding to the round hole and the long hole of the dial placed on the upper surface of the warning lens, and It is characterized in that a round hole and the elongated hole of the O over training lenses wherein a round hole and the elongated hole of the dial is matched respectively fitted to the same guide pins projecting from the casing.

[Action]

In the above configuration, the positions of the round hole and the long hole of the warning lens correspond to the positions of the round hole and the long hole formed on both sides of the dial disposed on the upper surface of the warning lens with the opening window interposed therebetween, respectively. Since the round holes and the long holes of the dial and the round holes and the long holes of the dial coincide with each other and are fitted to the same guide pins protruding from the case, there is a misalignment of the guide pins provided on the case. However, there is no positional deviation caused by the positional deviation of the guide pins between the warning lens and the opening window of the dial, and the pattern of the warning lens is at a predetermined position with respect to the opening window of the dial. Will be located. Especially,
Since the dial and the round hole of the warning lens are fitted to the same guide pin, even if there is a misalignment between the guide pins where the round hole and the long hole are fitted, it is not affected by this. The pattern of the warning lens is located at a predetermined position with respect to the opening window of the dial.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In this embodiment, the dial 3b of the fuel gauge 3 and the warning lens 9 are positioned with respect to the case as shown in FIG. In the figure, the same parts as those of the conventional art are denoted by the same reference numerals.

The positioning structure of the dial 3b and the warning lens 9 to the case will be described below with reference to FIG. 1 taking the case of the dial 3b of the fuel gauge 3 as an example.

When molding the case, the dial 3b and the warning lens 9
The guide pins 14a and 14b for commonly positioning are formed by integral molding.

The dial 3b is formed with a round hole 3m and a long hole 3n with the opening window 3c at the upper corner interposed therebetween. On the other hand, in the warning lens 9, the upper surface or the dial 3b is overlapped so that the pattern 9a is located in the opening window 3c. Holes 9n are respectively formed.
The round holes 3m and 9m are positioned by the guide pins 14a,
n and 9n are positioned by the guide pin 14b. Round hole 3m,
The diameter of 9 m and the minor diameter of the long holes 3n and 9n are substantially the same as the diameter of the guide pin.

The elongated holes 3n and 9n are for absorbing a positional shift of the guide pin during molding of the case, and the longitudinal direction thereof is the same as the straight line connecting the center thereof and the circular holes 3m and 9m, respectively.

It is to be noted that only the positioning of the round hole 3m and the elongated hole 3n on the case by the guide pins 14a and 14b causes the lower portion of the dial 3b to be free, and the dial 3b is likely to be misaligned. Therefore, an auxiliary guide pin 15 is formed in the case, and an auxiliary round hole 3h through which the auxiliary guide pin 15 is inserted is formed in the dial 3b. The diameter of the auxiliary round hole 3h is formed to be slightly larger than the diameter of the auxiliary guide pin 15 in order to absorb the displacement of the guide pins 14a, 14b and the auxiliary guide pin 15 at the time of molding the case.

〔effect〕

As described above, according to the present invention, since the round hole and the long hole of the warning lens and the round hole and the long hole of the dial are fitted to the same guide pin, respectively, the dial and the warning The relative displacement at the time of positioning the lens can be minimized, and the effect that the pattern of the warning lens is positioned at a predetermined position with respect to the opening window of the dial can be obtained.
