　図２は、この防水機構６の構成を示す分解斜視図であり、図３は、この防水機構６の断面図である。
　防水機構６は、Ｏリング１０をケース２に押圧して封止するようにケース２に導光部材１１が保持され、この導光部材１１のケース２とは逆側に、発光ダイオード７Ａ、７Ｂによる光源が設けられ、導光部材１１により発光ダイオード７Ａ、７Ｂの出射光が開口９Ａ、９Ｂに導かれ、これによりＯリング１０と導光部材１１とにより、充分に防水するようにして発光ダイオード７Ａ、７Ｂの点灯を視認できるようにする。 FIG. 2 is an exploded perspective view showing the configuration of the waterproof mechanism 6, and FIG. 3 is a cross-sectional view of the waterproof mechanism 6.
In the waterproof mechanism 6, the light source member 11 is held in the case 2 so as to press the O-ring 10 against the case 2 to seal the case 2, and the light emitting diodes 7A and 7B are on the opposite side of the light guide member 11 from the case 2. The light source is provided by the light guide member 11, and the emitted light of the light emitting diodes 7A and 7B is guided to the openings 9A and 9B, whereby the light emitting diode is sufficiently waterproofed by the O-ring 10 and the light guide member 11. Make the lighting of 7A and 7B visible.
　ここでＯリング１０は、この実施形態では、ケース２側より見て長円形形状により形成され、導光部材１１によりケース２に押圧して充分に雨水の進入を防止できるように、適度な弾性を備えるように形成される。またＯリング１０は、充分な耐候性を備え、さらには充分な耐薬品性、耐熱性を備えるように形成される。これによりＯリング１０は、シリコンゴム（ｓｉｌｉｃｏｎｅ　ｒｕｂｂｅｒ）、ニトリルゴム（ｎｉｔｒｉｌｅ　ｒｕｂｂｅｒ）等のゴム材料を適用することができる。 Here, in this embodiment, the O-ring 10 is formed in an oval shape when viewed from the case 2 side, and has appropriate elasticity so that the light guide member 11 can sufficiently press the O-ring 10 against the case 2 to prevent rainwater from entering.

It is formed so that the lighting of the light emitting diodes 7A and 7B can be visually recognized.
　さらに導光部材１１は、この発光面１４Ａ、１４Ｂの外側に、Ｏリング１０を収納する凹状溝１５が設けられ、これにより防水機構６は、Ｏリング１０の脱落を防止して確実にＯリング１０を配置できるように構成される。 Further, the light guide member 11 is provided with a concave groove 15 for accommodating the O-ring 10 on the outside of the light emitting surfaces 14A and 14B, whereby the waterproof mechanism 6 prevents the O-ring 10 from falling off and ensures the O-ring. It is configured so that 10 can be arranged.

The light-shielding plate 20 may be arranged directly between the light guide portions 12A and 12B by using an adhesive or the like. Further, it may be arranged on the light emitting surfaces 14A and 14B. As a result, the waterproof mechanism 6 can sufficiently prevent mixing of emitted light from adjacent light sources even when a plurality of light sources are arranged close to each other.
　ここで導光部材１１は、各種透光性の樹脂材料を広く適用することができ、例えばアクリル樹脂（ＰＭＭＡ）やポリカーボネイト（ＰＣ）等を適用することができる。

By providing a light emitting surface that emits light and a concave groove for accommodating the O-ring, even when an opening or the like is formed in the case, the O-ring and the light guide member can sufficiently waterproof the case. Further, it can be created by a simple configuration and work in which the light guide member is arranged so as to press and seal the O-ring and the light source is arranged.
　また導光部材のＯリングにより囲まれた部位にネジ穴を設け、このネジ穴にねじ込まれたネジにより、Ｏリングを押圧してケースに導光部材を保持することにより、汎用性の高い取り付け方法により導光部材を保持することができる。 Further, a screw hole is provided in a portion surrounded by the O-ring of the light guide member, and the O-ring is pressed by the screw screwed into the screw hole to hold the light guide member in the case, so that the light guide member can be mounted with high versatility. The light guide member can be held by the method.
　また受光面及び発光面を複数備えるようにして、隣接する受光面又は発光面の間に、隣接する受光面から入射した出射光の混入を防止する遮光板を設けることにより、近接して複数の光源を配置する場合でも、隣接する光源からの出射光の混入を充分に防止することができる。 Further, by providing a plurality of light receiving surfaces and light emitting surfaces and providing a light-shielding plate between the adjacent light receiving surfaces or light emitting surfaces to prevent mixing of emitted light incident from the adjacent light receiving surfaces, a plurality of light receiving surfaces are provided in close proximity to each other.
