【従来の技術】[Prior art]

従来のこの種の車両用灯具90における防水構造の例を示すものが図3であり 、この車両用灯具90のハウジング91は押出成形などによりパイプ状に形成さ れ両端に開口部91aを有するように形成されるものであり、夫々の前記開口部 91aには前記ハウジング91の外径とほヾ同一外径として形成されたキャップ 本体部92aと前記ハウジング91の内径よりも細い外径として形成された脚部 92bとから成るキャップ92が挿着されるものとされている。 FIG. 3 shows an example of a waterproof structure of a conventional vehicle lamp 90 of this type. A housing 91 of the vehicle lamp 90 is formed into a pipe shape by extrusion molding or the like, and has openings 91a at both ends. Each of the opening portions 91a is formed with an outer diameter smaller than the inner diameter of the housing and the cap main body portion 92a formed to have an outer diameter that is substantially the same as the outer diameter of the housing 91. A cap 92 including a leg portion 92b is inserted.

【0003】 このときに、前記開口部91aとキャップ本体部92aとの突接面、及び、ハ ウジング91の内径と脚部92bとの間隙でシールパッキン93を挟持して防水 が行われるものとされ、前記シールパッキン93のハウジング91の内径との接 触面には周方向に沿いリブ状に凸部93aが設けられ、前記ハウジング91へ脚 部92bを挿入するときの力を減じ作業を容易とすると共に、前記凸部93aが 容易に圧縮されるものとして防水機能を高めるものとされている。At this time, the seal packing 93 is sandwiched between the protruding surface of the opening 91a and the cap body 92a, and the gap between the inner diameter of the housing 91 and the leg 92b for waterproofing. The seal packing 93 is provided with a rib-shaped convex portion 93a along the circumferential direction on the contact surface with the inner diameter of the housing 91, which reduces the force for inserting the leg portion 92b into the housing 91 and facilitates the work. In addition, the projection 93a is easily compressed to enhance the waterproof function.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、前記した従来の構成においては、例えば前記ハウジング91の 断面形状、或いはハウジング91と脚部92bとの間の寸法誤差などにより前記 凸部93aに加わる圧縮力に不均一を生じるものとなり、これにより圧縮力の弱 い部分から浸水に至る問題点を生じ、また、前記車両用灯具90の車体への取付 時に加わる外部応力などによっても同様な問題点を生じるものとなり、この点の 解決が課題とされるものとなっていた。 However, in the above-described conventional configuration, the compression force applied to the convex portion 93a becomes non-uniform due to, for example, the sectional shape of the housing 91 or the dimensional error between the housing 91 and the leg portion 92b. As a result, there is a problem in that the portion with a weak compressive force leads to water infiltration, and the same problem occurs due to external stress applied when the vehicle lamp 90 is attached to the vehicle body. It was supposed to be.

【課題を解決するための手段】[Means for Solving the Problems]

本考案は前記した従来の課題を解決するための具体的な手段として、パイプ状 のハウジングにシールパッキンを介在させてキャップの脚部を挿入して成る車両 用灯具の防水構造において、前記キャップの脚部には前記ハウジングの内径に当 接する位置決め突起を前記ハウジングと脚部との間隙を均一とするように複数箇 所に設けられ、前記シールパッキンの前記位置決め突起に対応する位置には窓部 が設けられていることを特徴とする車両用灯具の防水構造を提供することで課題 を解決するものである。 As a concrete means for solving the above-mentioned conventional problems, the present invention provides a waterproof structure for a vehicular lamp, which comprises a pipe-shaped housing and a leg portion of the cap inserted with seal packing interposed therebetween. Positioning projections, which are in contact with the inner diameter of the housing, are provided at a plurality of positions on the legs so as to make the gap between the housing and the legs uniform, and a window is provided at a position corresponding to the positioning projections of the seal packing. The problem is solved by providing a waterproof structure for a vehicular lamp, which is characterized by being provided with.

【実施例】【Example】

つぎに、本考案を図に示す一実施例に基づいて詳細に説明する。図1及び図2 に符号1で示すものは車両用灯具であり、この車両用灯具1のハウジング2はパ イプ状に形成され、両端の開口部2aの夫々にはキャップ本体部3a及び脚部3 bで成るキャップ3が取付けられ、ハウジング2とキャップ3との両者でシール パッキン4を挟持して防水が行われるものである点は従来例のものと同様である 。 Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIGS. 1 and 2 denotes a vehicular lamp. A housing 2 of the vehicular lamp 1 is formed in a pipe shape, and a cap body 3a and a leg portion are provided in the openings 2a at both ends. The cap 3 made of 3b is attached, and the seal packing 4 is sandwiched between the housing 2 and the cap 3 for waterproofing, which is similar to the conventional example.

【0007】 ここで、本考案においては、上記従来の構成に加えてキャップ3のキャップ本 体部3aと脚部3bとの接続部に位置決め突起3cを設けるものであり、この位 置決め突起3cは前記ハウジング2の内径に当接して、前記ハウジング2の内径 とキャップ3の脚部3bの外径との間に生じる間隙を均一なものとする目的で設 けられるものである。Here, in the present invention, in addition to the above-mentioned conventional configuration, a positioning protrusion 3c is provided at a connecting portion between the cap body portion 3a of the cap 3 and the leg portion 3b. Is provided for the purpose of abutting the inner diameter of the housing 2 and making the gap between the inner diameter of the housing 2 and the outer diameter of the leg portion 3b of the cap 3 uniform.

【0008】 従って、例えば前記ハウジング2の内径が真円であれば120°間隔の3箇所 或いは90°間隔の4箇所、前記ハウジング2の内径が矩形であれば夫々の長辺 側に2箇所と夫々の短辺側に1箇所の合計6箇所と言うように適宜位置、適宜個 数で設けられるものとされ目的を達するものとされている。Therefore, for example, if the inner diameter of the housing 2 is a perfect circle, then three locations at 120 ° intervals or four locations at 90 ° intervals, and if the inner diameter of the housing 2 is rectangular, then two locations on each long side. It is said that the object is achieved by appropriately providing a suitable number of positions, such as one position on each short side, that is, a total of six positions.

【0009】 このときに、前記脚部3bはキャップ本体部3aの開口部2aとの突接でハウ ジング2の中心軸X方向には平行が保たれるものとなるので、前記位置決め突起 3cはハウジング2と脚部3bとの間隔の保持のみを目的とすれば良く、従って 前記した中心軸X方向への長さはそれ程に必要はないので、前記脚部3bの全長 にわたる必要はなく上記の目的を達するに充分な長さのごく短いものとして形成 される。At this time, the leg portion 3b is kept in parallel with the central axis X direction of the housing 2 by the abutting contact with the opening portion 2a of the cap body portion 3a. It is only necessary to maintain the distance between the housing 2 and the leg portion 3b, and therefore the length in the central axis X direction is not required so much. Therefore, it is not necessary to extend the entire length of the leg portion 3b, and It is formed as a very short piece that is long enough to reach its purpose.

【0010】 また、前記シールパッキン4には従来例と同様に凸部4aが設けられるものと されているが、加えて本考案により前記位置決め突起3cが設けられた位置に対 応しては窓部4bが設けられ、前記ハウジング2と突起3cとの当接を妨げない ものとされている。Further, the seal packing 4 is provided with a convex portion 4a as in the conventional example. In addition, according to the present invention, a window is provided corresponding to the position where the positioning protrusion 3c is provided. A portion 4b is provided so as not to prevent the contact between the housing 2 and the protrusion 3c.

【0011】 上記の構成としたことで、前記ハウジング2とキャップ3とを取付けたときに はハウジング2の内径と脚部3bとの間隔は均一なものとなり、これにより前記 両者に挟持されるシールパッキン4の凸部4aに対する圧縮量も全周で均一なも のとなって、圧縮量不足を一部に生じるなどの防水性能の低下の要因を完全に排 除するものとなる。尚、前記ハウジング2とキャップ3とに異なる方向の外部応 力が加えられた状態においても前記位置決め突起3cにより両者が接触している ことによりズレを生じることはなく防水効果が損なわれることはない。With the above configuration, when the housing 2 and the cap 3 are attached, the distance between the inner diameter of the housing 2 and the leg portion 3b becomes uniform, and as a result, the seal sandwiched between the two. The amount of compression of the packing 4 with respect to the convex portion 4a also becomes uniform over the entire circumference, and the factor of the deterioration of the waterproof performance such as partial insufficiency of the amount of compression is completely eliminated. Even when external forces in different directions are applied to the housing 2 and the cap 3, the positioning projections 3c make contact with each other so that no displacement occurs and the waterproof effect is not impaired. .

【考案の効果】[Effect of device]

以上に説明したように本考案により、キャップの脚部にはハウジングの内径に 当接する位置決め突起を前記ハウジングと脚部との間隙を均一とするように設け られ、シールパッキンの前記位置決め突起に対応する位置には窓部が設けられて いる車両用灯具の防水構造としたことで、例えばハウジングの断面形状、製造誤 差或いは使用時での外部応力の印加によるハウジングとキャップ両者の偏芯に起 因する防水効果の低下は、前記位置決め突起により両者の間隔を均一として保持 する作用により完全に防止されるものとなり、もって浸水の発生をなくして、こ の種の車両用灯具の信頼性の向上に極めて優れた効果を奏するものである。 As described above, according to the present invention, the leg portion of the cap is provided with the positioning protrusion that comes into contact with the inner diameter of the housing so as to make the gap between the housing and the leg portion uniform, and corresponds to the positioning protrusion of the seal packing. By providing a waterproof structure for the vehicular lamp that has a window at the position where the housing and the cap are eccentric due to, for example, the cross-sectional shape of the housing, manufacturing error, or external stress applied during use. The decrease in the waterproof effect caused by this is completely prevented by the action of the positioning protrusions to keep the gap between them uniform, thereby preventing the occurrence of flooding and improving the reliability of this type of vehicle lamp. It has an extremely excellent effect.
