Description

車両のランプユニットの防水構造Waterproof structure of vehicle lamp unit
　本発明は、ボディのランプ取付け凹面の縁部とバンパーの意匠面の上辺とに囲まれた窪み部にランプユニットが嵌め込まれ、そのランプユニットの背面開口部が前記ランプ取付け凹面の開口部に接続されて、前記ランプユニットが前記ランプ取付け凹面に取付けられる構成の車両のランプユニットの防水構造に関する。 In the present invention, a lamp unit is fitted in a recess surrounded by an edge of a lamp mounting concave surface of a body and an upper side of a design surface of a bumper, and a rear opening of the lamp unit is connected to an opening of the lamp mounting concave surface. Further, the present invention relates to a waterproof structure for a lamp unit of a vehicle having a configuration in which the lamp unit is mounted on the lamp mounting concave surface.
　乗用車Ｃのリヤランプユニット１００の取付け構造が図５（Ａ）（Ｂ）に記載されている。
　前記リヤランプユニット１００は、図５（Ａ）に示すように、リヤバンパー１１２の上側で、乗用車Ｃのボディ意匠面１２０に対して窪んだ状態で形成されたランプ取付け凹面１２２に嵌め込まれた状態で固定されている。上記構成では、リヤランプユニット１００の表面下端縁とリヤバンパー１１２の上辺との間には見切り隙Ｓが形成される。
　リヤランプユニット１００は、図５（Ｂ）に示すように、そのリヤランプユニット１００のハウジング１０３の背面に配線、コネクタ等が通される背面開口部１０３ｈが形成されており、その背面開口部１０３ｈがボディのランプ取付け凹面１２２に形成された開口部１２２ｈと重なるように構成されている。そして、リヤランプユニット１００の背面とランプ取付け凹面１２２との間に、背面開口部１０３ｈと開口部１２２ｈを囲むようにシール用パッキン１２３が挟持されている。これにより、リヤランプユニット１００がボディのランプ取付け凹面１２２に取付けられた状態で、リヤランプユニット１００の背面開口部１０３ｈとランプ取付け凹面１２２の開口部１２２ｈとの接続部分がシールされるようになる。 The mounting structure of the rear lamp unit 100 of the passenger car C is shown in FIGS.
As shown in FIG. 5 (A), the rear lamp unit 100 is fitted on a lamp mounting concave surface 122 formed on the upper side of the rear bumper 112 so as to be recessed with respect to the body design surface 120 of the passenger car C. It is fixed. In the above configuration, the parting gap S is formed between the lower end edge of the front surface of the rear lamp unit 100 and the upper side of the rear bumper 112.
As shown in FIG. 5B, the rear lamp unit 100 has a rear opening 103h through which wiring, connectors, and the like are formed on the rear surface of the housing 103 of the rear lamp unit 100, and the rear opening 103h is formed on the body. It is comprised so that it may overlap with the opening part 122h formed in the lamp | ramp attachment concave surface 122. A seal packing 123 is sandwiched between the rear surface of the rear lamp unit 100 and the lamp mounting concave surface 122 so as to surround the rear opening 103h and the opening 122h. Thereby, in a state where the rear lamp unit 100 is mounted on the lamp mounting concave surface 122 of the body, the connection portion between the rear opening 103h of the rear lamp unit 100 and the opening 122h of the lamp mounting concave surface 122 is sealed.
　しかし、図５（Ｂ）に示すように、リヤランプユニット１００とリヤバンパー１１２の見切り隙Ｓから試験的に高圧洗浄水（一点鎖線参照）を吹き込むと、吹き込み方向によっては、その高圧洗浄水がリヤランプユニット１００の背面側に回り込んでシール用パッキン１２３に吹き付けられることがある。このとき、前記高圧洗浄水の一部がシール用パッキン１２３を通過して背面開口部１０３ｈからリヤランプユニット１００の内側に浸入することがある。
　このような高圧洗浄水対策として、特許文献１の技術では遮水塀を設け、前記見切り隙Ｓから吹き込まれた高圧洗浄水を遮るようにしている。この技術を利用して、図５（Ｂ）の点線に示すように、リヤランプユニット１００のハウジング１０３の下面に遮水塀１２６を設置することが考えられる。 However, as shown in FIG. 5B, when high-pressure cleaning water (see the alternate long and short dash line) is experimentally blown from the parting gap S between the rear lamp unit 100 and the rear bumper 112, the high-pressure cleaning water may be used depending on the blowing direction. The unit 100 may wrap around the back side of the unit 100 and be sprayed onto the seal packing 123. At this time, a part of the high-pressure cleaning water may pass through the sealing packing 123 and enter the rear lamp unit 100 from the rear opening 103h.
As a countermeasure against such high-pressure washing water, the technique of Patent Document 1 is provided with a water shield so as to block the high-pressure washing water blown from the parting gap S. Using this technique, it is conceivable to install a water shield 126 on the lower surface of the housing 103 of the rear lamp unit 100 as shown by the dotted line in FIG.
特開平８－５５５０５号公報JP-A-8-55505
　しかし、前記遮水塀１２６によって、リヤランプユニット１００とリヤバンパー１１２の見切り隙Ｓから吹き込まれた高圧洗浄水を効率的に遮断するためには、その遮水塀１２６の先端（下端）を見切り隙Ｓよりも下方に突出させる必要がある。即ち、遮水塀１２６の下方への突出量を大きくする必要がある。しかし、遮水塀１２６の下方への突出量を大きくすると、リヤランプユニット１００をボディのランプ取付け凹面１２２に嵌め込む際に、その遮水塀１２６がリヤバンパー１１２の上辺１１２ｕと干渉し、リヤランプユニット１００をボディのランプ取付け凹面１２２に嵌め込むのが難しくなる。このため、遮水塀１２６の下方への突出量を希望する程度にまで大きくできず、満足な遮水性能を得ることが難しい。さらに、遮水塀１２６に衝突した高圧洗浄水がボディのランプ取付け凹面１２２の下方延長面１２４に衝突して反射し、シール用パッキン１２３に吹き付けられることがある。 However, in order to effectively shut off the high pressure washing water blown from the parting gap S between the rear lamp unit 100 and the rear bumper 112 by the water barrier 126, the tip (lower end) of the water barrier 126 is parted. It is necessary to project below S. That is, it is necessary to increase the downward protrusion amount of the water shield 126. However, if the downward protrusion amount of the water shield 126 is increased, when the rear lamp unit 100 is fitted into the lamp mounting concave surface 122 of the body, the water shield 126 interferes with the upper side 112u of the rear bumper 112, and the rear lamp unit It becomes difficult to fit 100 into the lamp mounting concave surface 122 of the body. For this reason, the amount of downward protrusion of the water shield 126 cannot be increased to a desired level, and it is difficult to obtain satisfactory water shielding performance. Further, the high-pressure cleaning water that has collided with the water shield 126 may collide with the lower extension surface 124 of the lamp mounting concave surface 122 of the body, be reflected, and be sprayed onto the seal packing 123.
　本発明は、上記問題点を解決するためになされたものであり、本発明が解決しようとする課題は、遮水塀を改良して見切り隙から吹き込まれた高圧洗浄水がランプハウジングの背面側に回り込まないようにし、水がランプユニット内に浸入しないようにすることである。 The present invention has been made to solve the above-mentioned problems, and the problem to be solved by the present invention is that the high-pressure washing water blown from the parting gap is improved on the rear side of the lamp housing. To prevent water from getting into the lamp unit.
　上記した課題は、各請求項の発明によって解決される。
　請求項１の発明は、車両のボディの意匠面に対して窪んだ状態でランプ取付け凹面が形成されて、そのランプ取付け凹面の縁部と連続するようにバンパーの意匠面の上辺が設けられており、その上辺と前記ランプ取付け凹面の縁部とに囲まれた窪み部にランプユニットが嵌め込まれ、そのランプユニットの背面開口部が前記ランプ取付け凹面の開口部に接続されて、前記ランプユニットが前記ランプ取付け凹面に取付けられる構成の車両のランプユニットの防水構造であって、前記ランプユニットの表面下端縁と前記バンパーの意匠面の上辺間に見切り隙が形成されており、前記ランプユニットには、前記バンパーの内側で、そのランプユニットの下面から下方に突出するように形成された遮水塀が前記見切り隙に沿うように設けられており、前記遮水塀は、弾性変形可能に構成されて、前記見切り隙から吹き込まれた高圧洗浄水を受けて弾性変形し、前記ランプ取付け凹面の下方延長面に当接することで、その高圧洗浄水が前記ランプユニットの背面の方向に回り込むのを禁止できるように構成されていることを特徴とする。 The above-described problems are solved by the inventions of the claims.

　本発明によると、遮水塀は、見切り隙から吹き込まれた高圧洗浄水に押されて弾性変形し、ボディのランプ取付け凹面の下方延長面に当接して、その高圧洗浄水が前記ランプユニットの背面方向に回り込むのを禁止できるように構成されている。
　このため、見切り隙から吹き込まれた高圧洗浄水がランプユニットの背面に回り込むことがなくなる。したがって、高圧洗浄水の一部がランプユニットの背面開口部とランプ取付け凹面の開口部との接続部分からランプユニットの内側に入り込むような不具合がない。 According to the present invention, the water shield is pushed and elastically deformed by the high pressure washing water blown from the parting gap, and comes into contact with the lower extension surface of the lamp mounting concave surface of the body. It is configured so that it can be prohibited to wrap around in the back direction.
For this reason, the high-pressure washing water blown from the parting gap does not flow around the back surface of the lamp unit. Therefore, there is no problem that a part of the high-pressure washing water enters the inside of the lamp unit from the connecting portion between the rear opening of the lamp unit and the opening of the lamp mounting concave surface.
　請求項２の発明によると、遮水塀は、ランプユニットがランプ取付け凹面の縁部とバンパーの意匠面の上辺とに囲まれた窪み部に嵌め込まれる際に、前記バンパーに当接して弾性変形することで、そのバンパーの上辺の位置を通過できるように構成されていることを特徴とする。
　このため、前記遮水塀を希望する突出寸法で製作しても、ランプユニットをボディのランプ取付け凹面に組付ける際に、その遮水塀が組付けの妨げにならない。 According to the invention of claim 2, when the lamp unit is fitted into the recess surrounded by the lamp mounting concave edge and the upper side of the design surface of the bumper, the water shield is brought into contact with the bumper and elastically deformed. By doing so, it is configured to be able to pass through the position of the upper side of the bumper.
For this reason, even if the water shield is manufactured with a desired projecting dimension, the water shield does not interfere with the assembly when the lamp unit is assembled to the lamp mounting concave surface of the body.
　請求項３の発明によると、遮水塀は、ランプユニットの下部に固定される固定部と、そのランプユニットの下面から下方に突出する塀本体部とから構成されており、前記固定部と塀本体部との境界位置に薄肉部が設けられていることを特徴とする。
　このため、塀本体部は、高圧洗浄水の押圧力を受けたとき、あるいは先端部がバンパーの上辺に当接したとき、常に固定部との境界位置で曲がるようになる。即ち、塀本体部が常に同じ位置で変形するようになるため、遮水性能等が一定化する。 According to a third aspect of the present invention, the water shield is composed of a fixing part fixed to the lower part of the lamp unit and a hook body part protruding downward from the lower surface of the lamp unit. A thin-walled portion is provided at a boundary position with the main body portion.
For this reason, the bag main body portion always bends at the boundary position with the fixed portion when receiving a pressing force of the high-pressure washing water or when the tip portion comes into contact with the upper side of the bumper. That is, since the bag main body portion is always deformed at the same position, the water shielding performance and the like are made constant.
　請求項４の発明によると、遮水塀は、高圧洗浄水の押圧力を受けない状態で、その遮水塀の先端部がランプ取付け凹面の下方延長面から離れていることを特徴とする。
　即ち、遮水塀に外力が加わっていない状態では、その遮水塀の先端部とランプ取付け凹面の下方延長面との間には隙間が形成されている。このため、例えば、ランプユニットの背面に水が付着しても、その水が遮水塀と下方延長面との隙間から下方に排出されて、溜まるようなことがない。 According to the invention of claim 4, the water shield is characterized in that the tip of the water shield is separated from the downward extension surface of the lamp mounting concave surface without receiving the pressing force of the high-pressure washing water.
That is, when no external force is applied to the water shield, a gap is formed between the tip of the water shield and the downwardly extending surface of the lamp mounting concave surface. For this reason, for example, even if water adheres to the back surface of the lamp unit, the water is not discharged from the gap between the water shield and the downward extension surface and collected.
　本発明によると、ランプユニットとバンパーの意匠面との間に形成された見切り隙から吹き込まれた高圧洗浄水がランプユニットの背面方向に回り込むことがなくなり、ランプユニット内に高圧洗浄水の一部が浸入するような不具合が発生しなくなる。 According to the present invention, the high-pressure cleaning water blown from the parting gap formed between the lamp unit and the design surface of the bumper does not flow around in the rear direction of the lamp unit, and a part of the high-pressure cleaning water enters the lamp unit. The problem of intrusion will not occur.

＜車両のボディ側の構造について＞
　車両のボディ３０には、図１、図２（Ａ）に示すように、バックドア６２との境界位置で、かつバンパー６４の上側位置にリヤランプユニット１０が取付けられるランプ取付け凹面３２（図２（Ａ）参照）が形成されている。ランプ取付け凹面３２は、リヤランプユニット１０が嵌め込まれるように、ボディ３０の意匠面３５に対して窪んだ状態で形成されており、そのランプ取付け凹面３２の縁形状がリヤランプユニット１０の外形に合わせられている。また、バンパー６４の意匠面６４ｅは、ボディ３０の意匠面３５と連続するように構成されており、その意匠面６４ｅの上辺６４ｕがランプ取付け凹面３２の縁部に連続するように構成されている。即ち、ボディ３０のランプ取付け凹面３２の縁部とバンパー６４の意匠面６４ｅの上辺６４ｕにより形成される窪み部にリヤランプユニット１０が嵌め込まれるようになっている。そして、この状態で、リヤランプユニット１０の表面下端縁とバンパー６４の意匠面６４ｅとの間には見切り隙Ｓ（図１参照）が形成されるようになる。
　ボディ３０のランプ取付け凹面３２には、図２（Ａ）、図３（Ａ）等に示すように、リヤランプユニット１０の背面開口部１４ｂ、支持突起１４ｔと重なる位置に前記光源の配線やコネクタ、及びその支持突起１４ｔが通される開口部３２ｈが形成されている。さらに、ボディ３０のランプ取付け凹面３２の下方には、バンパー６４の内側でそのランプ取付け凹面３２の位置から下方に延びる下方延長面３３が形成されている。 <About the structure of the vehicle body>
As shown in FIGS. 1 and 2A, the vehicle body 30 has a lamp mounting concave surface 32 (see FIG. 2 (FIG. 2 (A))) at which the rear lamp unit 10 is mounted at a boundary position with the back door 62 and at an upper position of the bumper 64. A)) is formed. The lamp mounting concave surface 32 is formed so as to be recessed with respect to the design surface 35 of the body 30 so that the rear lamp unit 10 is fitted, and the edge shape of the lamp mounting concave surface 32 is matched to the outer shape of the rear lamp unit 10. ing. The design surface 64 e of the bumper 64 is configured to be continuous with the design surface 35 of the body 30, and the upper side 64 u of the design surface 64 e is configured to be continuous with the edge of the lamp mounting concave surface 32. . That is, the rear lamp unit 10 is fitted into a recess formed by the edge of the lamp mounting concave surface 32 of the body 30 and the upper side 64u of the design surface 64e of the bumper 64. In this state, a parting gap S (see FIG. 1) is formed between the lower end edge of the front surface of the rear lamp unit 10 and the design surface 64e of the bumper 64.
As shown in FIGS. 2 (A), 3 (A), etc., the lamp mounting concave surface 32 of the body 30 has the light source wiring and connector at a position overlapping the rear opening 14b and the support projection 14t of the rear lamp unit 10. And the opening part 32h through which the support protrusion 14t is passed is formed. Further, a lower extension surface 33 is formed below the lamp mounting concave surface 32 of the body 30 and extends downward from the position of the lamp mounting concave surface 32 inside the bumper 64.
＜リヤランプユニット１０の防水構造について＞
　リヤランプユニット１０の背面とボディ３０のランプ取付け凹面３２との間には、図４（Ａ）に示すように、リヤランプユニット１０の背面開口部１４ｂとランプ取付け凹面３２の開口部３２ｈを囲むようにシール用パッキン３６が挟持されている。これにより、リヤランプユニット１０がボディ３０のランプ取付け凹面３２に取付けられた状態で、リヤランプユニット１０の背面開口部１４ｂとランプ取付け凹面３２の開口部３２ｈとの接続部分がシールされるようになる。
　また、リヤランプユニット１０の下面１４ｘ（ランプハウジング１４の下面ｘ）には、図２（Ａ）（Ｂ）に示すように、バンパー６４の内側で、そのリヤランプユニット１０の表面下端縁とバンパー６４の意匠面６４ｅとの間の見切り隙Ｓに沿うように延びる遮水塀２０が設けられている。 <Waterproof structure of rear lamp unit 10>
As shown in FIG. 4A, the rear opening 14b of the rear lamp unit 10 and the opening 32h of the lamp mounting concave surface 32 are surrounded between the rear surface of the rear lamp unit 10 and the lamp mounting concave surface 32 of the body 30. Sealing packing 36 is sandwiched. As a result, in a state where the rear lamp unit 10 is mounted on the lamp mounting concave surface 32 of the body 30, the connecting portion between the rear opening 14b of the rear lamp unit 10 and the opening 32h of the lamp mounting concave surface 32 is sealed.
2A and 2B, the lower surface 14x of the rear lamp unit 10 (the lower surface x of the lamp housing 14) is arranged on the inner side of the bumper 64 with the lower edge of the front surface of the rear lamp unit 10 and the bumper 64. A water shield 20 extending along the parting gap S between the design surface 64e is provided.
　遮水塀２０は、前記見切り隙Ｓから試験的に吹き込まれた高圧洗浄水を遮るための塀状部材であり、弾性変形可能なように、例えば、合成ゴムにより成形されている。遮水塀２０は、ランプハウジング１４の下面１４ｘに固定される帯板状の固定部２２と、その固定部２２に対してほぼ直角に立設されて、下方に突出する帯板状の塀本体部２４とから断面逆Ｌ字形に形成されている。そして、遮水塀２０の固定部２２と塀本体部２４との角部内側がランプハウジング１４の表面側を向くように、遮水塀２０はそのランプハウジング１４の下面１４ｘに固定される（図２（Ａ）（Ｂ）参照）。また、遮水塀２０は、図４（Ａ）に示すように、リヤランプユニット１０がボディ３０のランプ取付け凹面３２に取付けられた状態で、その遮水塀２０の塀本体部２４がランプ取付け凹面３２の下方延長面３３に接近する位置に配置されている（二点鎖線参照）。 The water shield 20 is a bowl-shaped member for blocking the high-pressure washing water blown from the parting gap S as a test, and is formed of, for example, synthetic rubber so as to be elastically deformable. The water shield 20 is a band plate-shaped fixing portion 22 fixed to the lower surface 14x of the lamp housing 14, and a band plate-shaped rod main body which is erected substantially perpendicular to the fixing portion 22 and protrudes downward. The section 24 is formed in an inverted L-shaped section. Then, the water shield 20 is fixed to the lower surface 14x of the lamp housing 14 so that the inner side of the corner portion between the fixing portion 22 of the water shield 20 and the main body portion 24 faces the surface side of the lamp housing 14 (FIG. 2 (A) (B)). Further, as shown in FIG. 4A, the water shield 20 has the main body 24 of the water shield 20 mounted on the lamp mounting concave surface in a state where the rear lamp unit 10 is mounted on the lamp mounting concave surface 32 of the body 30. It arrange | positions in the position which approaches the downward extension surface 33 of 32 (refer to a dashed-two dotted line).
　遮水塀２０の固定部２２と塀本体部２４との角部内側には、その角部に沿って断面円弧形の溝２３が形成されており、前記角部が薄肉になっている。これにより、遮水塀２０の塀本体部２４は、前後方向の外力を受けることで、固定部２２に対して前後に倒れ易くなる。
　即ち、遮水塀２０の角部が本発明の固定部と塀本体部との境界位置に相当する。
　また、遮水塀２０の塀本体部２４の突出寸法は、図４（Ａ）に示すように、リヤランプユニット１０がボディ３０のランプ取付け凹面３２に取付けられた状態で、その塀本体部２４の先端部（下端部）が前記見切り隙Ｓに対して下側に配置されるような寸法に設定されている。 A groove 23 having an arcuate cross section is formed along the corner between the fixed portion 22 and the main body portion 24 of the water shield rod 20, and the corner portion is thin. Thereby, the main body part 24 of the water shield 20 is easily tilted forward and backward with respect to the fixed part 22 by receiving an external force in the front-rear direction.
That is, the corner portion of the water shield rod 20 corresponds to the boundary position between the fixed portion and the rod body portion of the present invention.
Further, as shown in FIG. 4 (A), the protrusion dimension of the main body 24 of the water shield 20 is such that the rear lamp unit 10 is mounted on the lamp mounting concave surface 32 of the body 30 and The front end portion (lower end portion) is set so as to be disposed below the parting gap S.
＜ボディ３０に対するリヤランプユニット１０の取付けについて＞
　ボディ３０に対してリヤランプユニット１０を取付けるには、図２（Ａ）に示すように、ボディ３０のランプ取付け凹面３２の縁部とバンパー６４の意匠面６４ｅの上辺６４ｕとにより形成される窪み部（以下、ボディ窪み部という）の後方にリヤランプユニット１０を配置する。この状態で、リヤランプユニット１０を前記ボディ窪み部に嵌め込むように前方に移動させる。リヤランプユニット１０を前記ボディ窪み部に嵌め込む過程で、そのリヤランプユニット１０の下面１４ｘに設けられた遮水塀２０の塀本体部２４が、図３（Ａ）に示すように、バンパー６４の意匠面６４ｅに当接する。しかし、塀本体部２４は、遮水塀２０の角部内側に形成された溝２３（薄肉部）の働きで外力の方向に倒れ易く構成されているため、図３（Ｂ）に示すように、塀本体部２４が後方に倒れ、バンパー６４の上辺６４ｕの位置を通過できるようになる。即ち、遮水塀２０がリヤランプユニット１０の嵌め込み作業を妨げない。
　そして、リヤランプユニット１０の背面に設けられた支持突起１４ｔがボディ３０のランプ取付け凹面３２の開口部３２ｈに通され、リヤランプユニット１０が前記ボディ窪み部に嵌め込まれる。この状態で、図４（Ａ）に示すように、リヤランプユニット１０の背面開口部１４ｂとランプ取付け凹面３２の開口部３２ｈとの接続部分がシール用パッキン３６によってシールされる。また、リヤランプユニット１０が前記ボディ窪み部に嵌め込まれた状態で、そのリヤランプユニット１０の一部がランプ取付け凹面３２の一部と係合するようになる（図示省略）。そして、この状態で、リヤランプユニット１０をランプ取付け凹面３２にボルト止めすることで（図示省略）、リヤランプユニット１０はボディ３０に固定される。 <Attaching the Rear Lamp Unit 10 to the Body 30>
In order to attach the rear lamp unit 10 to the body 30, as shown in FIG. 2A, a recess formed by the edge of the lamp mounting concave surface 32 of the body 30 and the upper side 64u of the design surface 64e of the bumper 64. The rear lamp unit 10 is disposed behind the body recess (hereinafter referred to as a body recess). In this state, the rear lamp unit 10 is moved forward so as to be fitted into the body recess. In the process of fitting the rear lamp unit 10 into the body recess, the main body 24 of the water shield 20 provided on the lower surface 14x of the rear lamp unit 10 is designed as shown in FIG. 3 (A). It abuts on the surface 64e. However, as shown in FIG. 3 (B), the main body portion 24 is configured to easily fall in the direction of the external force due to the action of the groove 23 (thin wall portion) formed inside the corner portion of the impermeable barrier 20.塀 body part 24 falls backward, and can pass the position of upper side 64u of bumper 64. That is, the water shield 20 does not hinder the fitting operation of the rear lamp unit 10.
The support projection 14t provided on the rear surface of the rear lamp unit 10 is passed through the opening 32h of the lamp mounting concave surface 32 of the body 30, and the rear lamp unit 10 is fitted into the body recess. In this state, as shown in FIG. 4A, the connecting portion between the rear opening 14 b of the rear lamp unit 10 and the opening 32 h of the lamp mounting concave surface 32 is sealed by the sealing packing 36. Further, in a state where the rear lamp unit 10 is fitted in the body recess, a part of the rear lamp unit 10 comes into engagement with a part of the lamp mounting concave surface 32 (not shown). In this state, the rear lamp unit 10 is fixed to the body 30 by bolting the rear lamp unit 10 to the lamp mounting concave surface 32 (not shown).
＜遮水塀２０の動作について＞
　次に、遮水塀２０の動作について説明する。
　図４（Ａ）に示すように、リヤランプユニット１０の表面下端縁とバンパー６４の意匠面６４ｅとの間の見切り隙Ｓから高圧洗浄水（一点鎖線参照）が吹き込まれると、高圧洗浄水はランプハウジング１４の下面１４ｘに固定された遮水塀２０の塀本体部２４に衝突する。これにより、塀本体部２４は、図４（Ｂ）に示すように、高圧洗浄水の押圧力で前方（図４で右方向）に倒れ、その塀本体部２４の先端部の外側がボディ３０のランプ取付け凹面３２の下方延長面３３に当接する。このとき、塀本体部２４が曲がるため、塀本体部２４の先端部はボディ３０の下方延長面３３に沿うようになり、塀本体部２４の先端部とボディ３０の下方延長面３３との密着性が向上する。即ち、リヤランプユニット１０のランプハウジング１４の下面１４ｘと、ボディ３０の下方延長面３３との間が遮水塀２０の塀本体部２４によって塞がれるため、高圧洗浄水がランプハウジング１４の背面方向に回り込まなくなる。このため、高圧洗浄水がランプハウジング１４の背面とボディ３０のランプ取付け凹面３２との間に挟持されたシール用パッキン３６に吹き付けられるようなことがなくなり、水がシール用パッキン３６を通過して背面開口部１４ｂからリヤランプユニット１０の内部に浸入するようなことがない。
　また、遮水塀２０の塀本体部２４の先端部は、高圧洗浄水の押圧力を受けない状態で、ボディ３０のランプ取付け凹面３２の下方延長面３３からは離れた状態に保持されている（図４（Ｂ）二点鎖線参照）。このため、例えば、シール用パッキン３６の部分に水が付着していても、その水を遮水塀２０の塀本体部２４と下方延長面３３との隙間から下方に排出することが可能になる。 <About the operation of the water barrier 20>
Next, the operation of the water barrier 20 will be described.
As shown in FIG. 4A, when high-pressure cleaning water (see the alternate long and short dash line) is blown from the parting gap S between the lower surface edge of the rear lamp unit 10 and the design surface 64e of the bumper 64, the high-pressure cleaning water is It collides with the main body 24 of the water shield 20 fixed to the lower surface 14x of the housing 14. As a result, as shown in FIG. 4B, the heel body 24 falls forward (rightward in FIG. 4) by the pressing force of the high-pressure washing water, and the outer side of the tip of the heel body 24 is the body 30. The lamp mounting concave surface 32 abuts on the lower extension surface 33. At this time, since the heel body portion 24 bends, the distal end portion of the heel body portion 24 comes along the downward extension surface 33 of the body 30, and the distal end portion of the heel body portion 24 and the lower extension surface 33 of the body 30 are in close contact with each other. Improves. That is, since the space between the lower surface 14x of the lamp housing 14 of the rear lamp unit 10 and the lower extension surface 33 of the body 30 is blocked by the main body 24 of the water shield 20, the high-pressure cleaning water flows in the rear direction of the lamp housing 14. No longer wrap around. For this reason, the high pressure washing water is not sprayed on the sealing packing 36 sandwiched between the back surface of the lamp housing 14 and the lamp mounting concave surface 32 of the body 30, and the water passes through the sealing packing 36. There is no entry into the rear lamp unit 10 from the rear opening 14b.
Further, the tip end portion of the main body portion 24 of the water shield 20 is held in a state separated from the downward extension surface 33 of the lamp mounting concave surface 32 of the body 30 without receiving the pressing force of the high-pressure washing water. (See FIG. 4 (B) two-dot chain line). For this reason, for example, even if water adheres to the portion of the seal packing 36, it is possible to discharge the water downward from the gap between the main body portion 24 of the water shield 20 and the downward extension surface 33. .
＜本実施形態に係るリヤランプユニット１０の防水構造の長所について＞
　本実施形態に係るリヤランプユニット１０の防水構造によると、遮水塀２０は、見切り隙Ｓから吹き込まれた高圧洗浄水に押されて弾性変形し、ボディ３０のランプ取付け凹面３２の下方延長面３３に当接して、その高圧洗浄水がリヤランプユニット１０の背面方向に回り込むのを禁止できるように構成されている。このため、見切り隙Ｓから吹き込まれた高圧洗浄水がリヤランプユニット１０の背面に回り込むことがなくなる。したがって、高圧洗浄水の一部がリヤランプユニット１０の背面開口部１４ｂとランプ取付け凹面３２の開口部３２ｈとの接続部分からリヤランプユニット１０の内側に入り込むような不具合がない。
　また、遮水塀２０は、リヤランプユニット１０がボディ３０のランプ取付け凹面３２に嵌め込まれる際に、バンパー６４の意匠面６４ｅに当接して弾性変形することで、そのバンパー６４の上辺６４ｅの位置を通過できるように構成されている。このため、遮水塀２０を希望する突出寸法で製作しても、リヤランプユニット１０をボディ３０のランプ取付け凹面３２に組付ける際に、その遮水塀２０が組付けの妨げにならない。 <Advantages of Waterproof Structure of Rear Lamp Unit 10 According to this Embodiment>
According to the waterproof structure of the rear lamp unit 10 according to the present embodiment, the water shield 20 is elastically deformed by being pushed by the high-pressure washing water blown from the parting gap S, and the lower extension surface 33 of the lamp mounting concave surface 32 of the body 30. The high-pressure washing water can be prevented from turning around in the rear direction of the rear lamp unit 10. For this reason, the high-pressure washing water blown from the parting gap S does not flow around to the rear surface of the rear lamp unit 10. Therefore, there is no problem that a part of the high-pressure washing water enters the inside of the rear lamp unit 10 from the connection portion between the rear opening 14b of the rear lamp unit 10 and the opening 32h of the lamp mounting concave surface 32.
Further, when the rear lamp unit 10 is fitted into the lamp mounting concave surface 32 of the body 30, the water shield 20 is brought into contact with the design surface 64e of the bumper 64 and elastically deformed so that the position of the upper side 64e of the bumper 64 is changed. It is configured to pass through. For this reason, even if the water shielding rod 20 is manufactured with a desired projecting dimension, when the rear lamp unit 10 is assembled to the lamp mounting concave surface 32 of the body 30, the water shielding rod 20 does not hinder the assembly.
　また、遮水塀２０の塀本体部２４は、高圧洗浄水の押圧力を受けたとき等、常に同じ位置で曲がるようになるため、遮水性能が一定化する。
　また、遮水塀２０に外力が加わっていない状態では、その遮水塀２０の先端部とランプ取付け凹面３２の下方延長面３３との間には隙間が形成されている。このため、例えば、リヤランプユニット１０の背面に水が付着しても、その水が遮水塀２０と下方延長面３３との隙間から下方に排出されて、溜まるようなことがなくなる。 In addition, since the main body 24 of the water barrier 20 is always bent at the same position when receiving the pressing force of the high-pressure washing water, the water blocking performance is made constant.
Further, when no external force is applied to the water shield 20, a gap is formed between the tip of the water shield 20 and the downward extension surface 33 of the lamp mounting concave surface 32. For this reason, for example, even if water adheres to the rear surface of the rear lamp unit 10, the water is not discharged from the gap between the water shield 20 and the downward extension surface 33 and accumulated.
