The overhanging portion 62 is flange-shaped, and the two (pair) of the overhanging portions 62 located on the upper side of the four overhanging portions 62 are each provided with a first positioning hole 63a and a second positioning hole 63b. The third positioning hole 63c is provided in a portion protruding outward from the center of the terminal holding portion. The (two) positioned portions 63 provided in the pair of overhanging portions to correspond to the first and second openings refer to the first positioning hole 63a and the second positioning hole 63b. In FIG. 4, the symbol L1 indicates the center line along the long hole direction of the first positioning hole 63a, the symbol L2 indicates the center line along the long hole direction of the second positioning hole 63b, and the intersection point where the center line L1 and the center line L2 intersect is approximately aligned with the center point of the third positioning hole 63c.

The display panel 70 is a panel body on which various display design parts are formed, and is disposed to the left, right, and above the display means 10 so as not to overlap with the display means 10 when the display device M is viewed from the viewer's side. In other words, the display panel 70 here comprises a first panel portion 71 provided along one side portion P1 located above the display means 10 as shown in FIG. 5, and a pair of second panel portions 72 provided along a pair of opposing side portions P2 of the display means 10 located at a position different from the one side portion P1 (i.e., to the left and right of the display means 10).

The first panel portion 71 has a plurality of first display design portions 71a arranged side by side, each of which is made up of various warning display marks. The pair of second panel portions 72 each have a second display design portion 72a arranged on each of which is made up of a directional indicator mark. The first display design portion 71a and the second display design portion 72a are capable of illuminating when illuminated by an indicator light source (not shown) mounted on the circuit board 30. Note that FIG. 1 shows the first display design portion 71a and the second display design portion 72a in a state where they are not illuminated.

In this case, a pair (multiple) of first openings 72b consisting of substantially elongated through-holes are formed in the pair of second panel portions 72 (display panel 70) at positions corresponding to the positioning portions 24 (specifically, the first positioning pin 24a and the second positioning pin 24b). One of the first openings 72b thus provided in each of the pair of second panel portions 72 is provided for passing the first positioning pin 24a and the first screw fixing portion 25a toward the holding member 60 side, and the other of the first openings 72b is provided for passing the second positioning pin 24b and the second screw fixing portion 25b toward the holding member 60 side.

The panel holding member 80 has an external shape that is generally the same as that of the display panel 70, and includes a first panel holding portion 81 that holds the first panel portion 71 of the display panel 70, and a pair of second panel holding portions 82 that hold the pair of second panel portions 72 of the display panel 70, as shown in FIG. 6. The panel holding portions 81 and 82 are provided with holes T for directing the illumination light to the display design portions 71a and 72a. Although not shown in detail here, the panel holding member 80 (on which the display panel 70 is placed) is fixed to the circuit board 30 using appropriate fixing means such as fixing screws and/or hooks.

In this case, a pair (multiple) of second openings 82a, each of which is a substantially elongated through-hole, are formed in the pair of second panel holding parts 82 (panel holding members 80) so as to communicate with the first opening 72b. The second openings 82a thus provided in each of the second panel holding parts 82 are provided in conjunction with the first openings 72b to allow the first positioning pin 24a and the second positioning pin 24b to pass through toward the holding member 60.

Here, an example of a fixing operation for positioning and fixing each of the positioning pins 24a-24c (cover member 20) to each of the positioning holes 63a-63c (holding member 60) will be described. Prior to this fixing operation, the circuit board 30 (on which the holding member 60 housing the light guide member 50 and display means 10 is placed) and the panel holding member 80 (on which the display panel 70 is placed) are fixed by the appropriate fixing means described above. At this time, the four board holes 32 of the circuit board 30 and the holes H1-H4 of the holding member 60 are respectively overlapped.

First, the cover member 20 and the holding member 60 to which the circuit board 30, the panel holding member 80, etc. are fixed are spaced apart to a certain extent, and the cover member 20 and the holding member 60 are aligned so that the screw fixing portions 25a-25d face the holes H1-H4, respectively. Then, for example, when the cover member 20 is translated toward the holding member 60, the first positioning pin 24a and the first screw fixing portion 25a pass through (insert) the openings 72b, 82a in sequence, and the second positioning pin 24b and the second screw fixing portion 25b pass through (insert) the openings 72b, 82a in sequence. In other words, this means that the first screw fixing portion 25a penetrates the first and second openings 72b, 82a together with the first positioning pin 24a, and the second screw fixing portion 25b penetrates the first and second openings 72b, 82a together with the second positioning pin 24b.

Then, when the cover member 20 is further moved in parallel toward the holding member 60, the positioning pins 24a to 24c are positioned in the positioning holes 63a to 63c, and the screw fixing parts 25a to 25d are in close contact with the holes H1 to H4. At this time, the third positioning pin 24c is directly positioned in the third positioning hole 63c because there is no display panel 70 or panel holding member 80 directly below it. Finally, the cover member 20 is fixed to the holding member 60 by screwing the screws that pass through the four board holes 32 and the holes H1 to H4 into the screw fixing parts 25a to 25d. In this way, in this example, the cover member 20, the holding member 60, and the circuit board 30 can be fixed together by fixing the screws that pass through the four board holes 32 and the holes H1 to H4 to the screw fixing parts 25a to 25d.

The housing 90 includes an upper housing 91 and a lower housing 92 that is provided to be paired with the upper housing 91 (see FIG. 2). The upper housing 91 is configured as a see-through member formed from a translucent synthetic resin material, and is disposed in front of the cover member 20. The lower housing 92 is a resin case formed from a synthetic resin material, and is fixed to the upper housing 91 using an appropriate fixing means. The display means 10, cover member 20, circuit board 30, light guide member 50, holding member 60, display panel 70, panel holding member 80, etc. are accommodated in the spatial region formed between the upper housing 91 and the lower housing 92.

As described above, according to this embodiment, the cover member 20 has an opening 21 that defines the visible area of the display means 10 and a positioning portion 24 that extends toward the display means 10, a holding member 60 that holds the display means 10, a display panel 70 in which a first opening 72b is formed at a position corresponding to the positioning portion 24, and a panel holding member 80 that holds the display panel 70 and has a second opening 82a formed at a position corresponding to the first opening 72b. The holding member 60 has first and second positioning holes 63a, 63b (positioned portion 63) in which the first and second positioning pins 24a, 24b (positioning portion 24) that pass through the first and second openings 72b, 82a are positioned.

Since the positioning portion 24 is integrally formed with the cover member 20 located inside the upper housing 91, the positioning structure consisting of the positioning portion 24 (positioning pin) and the positioned portion 63 (positioning hole) is formed inside the outer casing of the display device as in the conventional case. This eliminates the need to install the positioning structure on the outer casing, which has the advantage of making it possible to miniaturize the housing and preventing the device from becoming larger.

The present invention is not limited to the above-described embodiment and drawings. Changes (including deletion of components) can be made to the embodiment and drawings as appropriate without changing the gist of the present invention.

For example, in the above description, the first opening 72b and the second opening 82a are configured as through-holes of approximately elongated holes, but the shapes of the first opening 72b and the second opening 82a can be any shape that allows the first positioning pin 24a and the first screw fixing portion 25a (the second positioning pin 24b and the second screw fixing portion 25b) to be inserted therethrough, and for example, at least one of the first opening 72b and the second opening 82a may be a notch portion rather than a through-hole of approximately elongated holes. For example, FIG. 7 shows an example in which the first opening 72b provided in the display panel 70 is a notch portion.
