る。 FIG. 1 shows a conventional example of such a meter.
Reference numeral 1 denotes a case with a U-shaped cross section that stores and fixes the instrument body 2 and the lighting member 3 on the bottom wall, and 4 reflects the irradiated light from the lighting member 3 and irradiates it to the instrument body 2 side, or the interior of the case 1. A substantially flat facing plate having a cutout window provided in the front of a folded portion 5 bent outward from the front opening end of the case 1 for the purpose of covering a portion not directly related to display reading; 6 is a cross section; The glass 8 is provided on the facing plate 4 by fitting a U-shaped gasket 7 around its periphery, and the lower periphery of the glass 8 is bent and attached sharply to the bent portion 5 of the case 1, and the facing plate 4 and the glass 6 are Each fitted gasket 7 is attached to case 1.
A ring-shaped front cover 9 fixed to the front opening end of the case 1 is a cup-shaped rear cover fixed to the rear of the case 1 with screws 10 to cover the rear side of the case 1.

く完全な密封状態にすることが必要であつた。 By the way, such instruments are exposed to the external atmosphere and are used in an environment where they are directly exposed to factors such as wind, rain, dust, etc. that adversely affect the display operation of the instrument body 2. The inside of the meter to be stored and fixed must be structured so that the above-mentioned factors cannot easily enter, and in particular, the front side of the meter needs to be completely sealed without any gaps.

とがあつた。 For this reason, the facing plate 4 and glass 6 are
There has been a method in which the front cover 8 made of a metal material such as iron is caulked to the bent portion 5 of the case 1 through a screw, and is assembled to the front of the case 1. According to this method, a good sealing condition can be established. Although it is possible to do so, it takes time to do the work, and the front cover 8 has been caulked once.
could not be used again, and furthermore, this assembly structure sometimes made work extremely difficult or impossible depending on the shape of the instrument. That is, case 1
After arranging the instrument body 2 and lighting member 3 at the predetermined positions of the
Place the glass 6 provided with a The process involves reversing the direction, setting it on a jig, and using a press machine to press and bend the lower edge of the front cover 8 toward the rear side of the folded part 5 of the case 1. The positional relationship had to be taken care of, the number of steps was large, and time and skill were required. Furthermore, once you have caulked the front cover 8 and noticed that foreign matter such as dust has entered the case 1 and removed the front cover 8, you will not be able to reassemble it using the same front cover 8, and you will have to use new and separate parts. Removal is not desirable because the front cover 8 has to be replaced with another one, and even if removal is unavoidable, it is not easy to remove the caulked part, and furthermore, once the front cover 8 is caulked, it cannot be used again, so there are unnecessary parts. is required, which increases parts costs. Furthermore, caulking work can be performed on instruments with relatively simple shapes, such as circular or square shapes (not shown) as shown in Figure 2.
For instruments with complicated shapes, sloped display surfaces, or large instruments, it may be difficult to set the front cover 8 on the jig if the front cover 8 has to be caulked, or the pressure from the press machine may not be uniform. It is very difficult to avoid and
Occasionally, problems such as torsional stress being applied to the glass 6 and breakage may occur due to uneven pressure distribution.

とするものである。 This idea was devised by focusing on these conventional problems, and involves covering the front opening end of the case in which the instrument body and lighting components are housed and fixed, and fixing it to the case. Furthermore, by surrounding these with a splittable cover and storing and fixing the case, the instrument body and lighting components are held in a double storage structure of the case, glass, and cover, which requires time-consuming processes such as caulking work. Moreover, the sealing performance is equivalent to or better than that of the conventional structure, and anyone can easily assemble or remove it.
Moreover, it is an object of the present invention to provide an instrument body housing structure that can strictly prevent factors that adversely affect the display operation of the instrument body, such as wind, rain, and dust, from entering the case.

カバーである。 In FIG. 3, reference numeral 11 is a case in which the instrument body 12 and the lighting member 13 are attached to the bottom wall, and 14 is a case that reflects the irradiated light from the lighting member 13 to the instrument main body 12.
Case 1 is used for the purpose of illuminating the side or covering parts of the case 11 that are not directly related to display reading.
a facing plate having a cutout window portion fixed to the case 11 with screws 15 so as to be located on the front side inside the case 1;
16 is a screw 1 that covers the front opening end of the case 11 so that the side wall is in contact with the outer surface of the side wall of the case 11.
At 7, a glass made of a transparent synthetic resin, for example, an acrylic resin, is attached to the case 11. At 18, the inner wall of the front opening end is in contact with the front peripheral edge of the glass 16, and the side wall is made of glass. 16 or a substantially cylindrical front cover made of a synthetic resin, such as ABS resin, that covers the outer surface of the side wall of the case 11 and is attached to the case 11 side with screws 17 or other screws that attach the glass 16 to the case 11; After being formed of the same material as the front cover 18 which wraps around the rear side and whose side wall covers the outer surface of the side wall of the case 11 or the glass 16 and comes into contact with the rear end of the front cover 18 and is attached to the case 11 with screws 20. It's a cover.

このように、この構造は、計器本体１２や照明
部材１３をケース１１とガラス１６および前カバ
ー１８と後カバー１９との２重収納構造とするこ

悪影響を与える因子がケース１１内部に浸入しに
くい構造となり、よつて計器本体１２を常に良好
な状態に保持することができるもので従来のかし
めによる構造に比べて密封性能の遜色もない。 In this way, this structure has a double storage structure for the instrument body 12 and the lighting member 13, which includes the case 11 and the glass 16, and the front cover 18 and the rear cover 19. This structure prevents factors that adversely affect the inside of the case 11 from penetrating into the inside of the case 11, and thus the instrument body 12 can always be maintained in a good condition, and its sealing performance is comparable to that of the conventional caulking structure.

しかも、ネジ締めによる取り付け構造であるこ
とから比較的作業が容易で誰でも簡単に作業を行
うことができ、作業者の経験の有無にかかわらず

消される。 Moreover, since the installation structure is screwed, it is relatively easy to work with, and anyone can easily perform the work, and regardless of whether the operator has experience or not, it is possible to obtain an instrument body storage structure of almost the same quality. . In addition, even if foreign matter such as dust is found inside the case 11 after assembly, it can be easily removed, and after removing the foreign matter, the same parts can be reassembled as they are. Uneconomical problems will be resolved.

る。 For example, motorcycle instruments are becoming larger in size, with the ability to display multiple items such as remaining fuel level, coolant temperature, gear position, suspension air pressure, etc. in addition to the conventional running speed and engine speed. The shape also changes from simple circles and squares to ellipses and polygons, and furthermore, glass
6 has also become more complex, changing from a planar shape to a sloped shape or a curved shape. It is difficult to apply the conventional assembly work to such instruments as is, as mentioned above in the conventional example section, but with this structure, there is no problem, that is, the glass 1
6 can be assembled without applying unnecessary stress, and it is possible to provide an instrument body storage structure that satisfies the various demands of recent instruments.
