本発明によると、シール部材の外周縁の周方向全体と内周縁の周方向全体とがアウタパネルとランプハウジングとのいずれか、あるいは双方に設けられた突部によって、他の部分よりも大きく押圧され、他の部位よりも大きく弾性変形する。このため、ランプハウジングの嵌め込み部は、シール部材の外周縁の部分と内周縁の部分とにより径方向において二ヶ所でシールされる。即ち、径方向において二重シール状態となる。したがって、従来の一重シール状態の場合と比較してシール性が格段に向上する。
さらに、一枚のシール部材で二重シールを行なえるため、さほどコストアップにならない。 According to the present invention, the entire circumferential direction of the outer peripheral edge of the sealing member and the entire circumferential direction of the inner peripheral edge are pressed more greatly than the other parts by the protrusions provided on either or both of the outer panel and the lamp housing. The elastic deformation is greater than other parts. For this reason, the fitting portion of the lamp housing is sealed at two locations in the radial direction by the outer peripheral portion and the inner peripheral portion of the seal member. That is, a double seal state is obtained in the radial direction. Therefore, the sealing performance is remarkably improved as compared with the conventional single seal state.
Furthermore, since double sealing can be performed with a single sealing member, the cost is not significantly increased.

即ち、アウタパネルの開口エッヂ部をシール部材の内周縁を押圧する突部として使用できるため、前記アウタパネル側に特別に突部を形成しなくてもよくなり、コストを抑えることができる。 According to the second aspect of the present invention, the outer peripheral edge of the seal member is sandwiched between the protrusions formed on the seal surface of the outer panel and the seal surface of the lamp housing, and the inner peripheral edge of the seal member is the protrusion. It is configured to be sandwiched between an edge portion and a seal surface of the lamp housing.

請求項３の発明によると、シール部材の内周端は、アウタパネルの開口部を通過して、その開口部の内側に入り込んでいることを特徴とする。
このため、アウタパネルの開口エッヂ部とランプハウジングのシール面間にシール部材を挟持し易くなる。 According to the invention of claim 3, the inner peripheral end of the seal member passes through the opening of the outer panel and enters the inside of the opening.
For this reason, it becomes easy to clamp a sealing member between the opening edge part of an outer panel, and the sealing surface of a lamp housing.

＜リヤランプユニット３０の嵌め込み部のシール構造について＞
リヤランプユニット３０のランプハウジング３２とドアアウタパネル２２の開口部２２ｘ周縁間はシール部材４０によってシールされている。
シール部材４０は、例えば、発泡性のゴム材により構成されており、図３に示すように、一定の厚み寸法で略楕円形をしたリング状に形成されている。そして、そのシール部材４０のリング幅Wが、図４、図５に示すように、ランプハウジング３２のフランジ部３２３のシール面３２４全体と、ハウジング本体部３２１の外周面であってドアアウタパネル２２の開口部２２ｘに通される部分とその近傍を覆うことができる寸法に設定されている。即ち、シール部材４０の外周縁４３の部分がランプハウジング３２のフランジ部３２３のシール面３２４を覆い、内周縁４４の部分がハウジング本体部３２１の外周面を覆うようになる。
このため、ハウジング本体部３２１の外周面のうちでシール部材４０の内周縁４４によって覆われる部分がフランジ部３２３のシール面３２４とともに本発明のシール面として機能するようになる。したがって、シール部材４０の内周縁４４によって覆われる部分を、以後、シール面３２１ｒと呼ぶことにする。 <About the sealing structure of the fitting portion of therear lamp unit 30>
A gap between thelamp housing 32 of the rear lamp unit 30 and the periphery of the opening 22x of the door outer panel 22 is sealed by a seal member 40.
Theseal member 40 is made of, for example, a foamable rubber material, and is formed in a ring shape having a substantially elliptical shape with a constant thickness as shown in FIG. 4 and 5, the ring width W of the seal member 40 is the entire seal surface 324 of the flange portion 323 of the lamp housing 32 and the outer peripheral surface of the housing main body portion 321, and the door outer panel 22. The dimension is set so as to cover the portion that passes through the opening 22x and the vicinity thereof. That is, the outer peripheral edge 43 of the seal member 40 covers the seal surface 324 of the flange 323 of the lamp housing 32, and the inner peripheral edge 44 covers the outer peripheral surface of the housing main body 321.
Therefore, a portion of the outer peripheral surface of the housingmain body 321 covered by the inner peripheral edge 44 of the seal member 40 functions as the seal surface of the present invention together with the seal surface 324 of the flange portion 323. Therefore, the portion covered by the inner peripheral edge 44 of the seal member 40 is hereinafter referred to as a seal surface 321r.
リヤランプユニット３０のランプハウジング３２とドアアウタパネル２２の開口部２２ｘ周縁間はシール部材４０によってシールされている。
シール部材４０は、例えば、発泡性のゴム材により構成されており、図３に示すように、一定の厚み寸法で略楕円形をしたリング状に形成されている。そして、そのシール部材４０のリング幅Wが、図４、図５に示すように、ランプハウジング３２のフランジ部３２３のシール面３２４全体と、ハウジング本体部３２１の外周面であってドアアウタパネル２２の開口部２２ｘに通される部分とその近傍を覆うことができる寸法に設定されている。即ち、シール部材４０の外周縁４３の部分がランプハウジング３２のフランジ部３２３のシール面３２４を覆い、内周縁４４の部分がハウジング本体部３２１の外周面を覆うようになる。
このため、ハウジング本体部３２１の外周面のうちでシール部材４０の内周縁４４によって覆われる部分がフランジ部３２３のシール面３２４とともに本発明のシール面として機能するようになる。したがって、シール部材４０の内周縁４４によって覆われる部分を、以後、シール面３２１ｒと呼ぶことにする。 <About the sealing structure of the fitting portion of the

The
Therefore, a portion of the outer peripheral surface of the housing
ドアアウタパネル２２の開口部２２ｘの周縁には、ランプハウジング３２のフランジ部３２３のシール面３２４が平行に重なるように構成されたシール面２２ｓが形成されている。さらに、ドアアウタパネル２２の開口部２２ｘのエッヂ（以下、開口エッヂ部２２０ｘという）は、ランプハウジング３２のハウジング本体部３２１のシール面３２１ｒを覆うシール部材４０の内周縁４４をほぼ直角方向（半径方向）から押圧できるように構成されている。
At the periphery of the opening 22x of the door outer panel 22, a seal surface 22s configured so that the seal surface 324 of the flange portion 323 of the lamp housing 32 overlaps in parallel is formed. Further, an edge of the opening 22x of the door outer panel 22 (hereinafter referred to as an opening edge 220x) is substantially perpendicular to the inner peripheral edge 44 of the seal member 40 covering the seal surface 321r of the housing body 321 of the lamp housing 32 (radial direction). ) Can be pressed.
前記リヤランプユニット３０をドアアウタパネル２２に取付ける場合には、先ず、図６、図７に示すように、シール部材４０の外周縁４３の裏面をドアアウタパネル２２の開口部２２ｘ周縁のシール面２２ｓに面接触させた状態で、そのシール部材４０を断面略Ｌ字形に曲げ、シール部材４０内周縁４４をドアアウタパネル２２の開口部２２ｘ内に押し込むようにする。即ち、シール部材４０により、ドアアウタパネル２２の開口部２２ｘ周縁を覆うとともに、その開口部２２ｘの開口エッヂ部２２０ｘを覆うようにする。次に、この状態で、リヤランプユニット３０のランプハウジング３２をドアアウタパネル２２の凹部２２ｋに収納し、そのランプハウジング３２の底部分３２１ｂをドアアウタパネル２２の開口部２２ｘに嵌め込むようにする。
When the rear lamp unit 30 is attached to the door outer panel 22, first, as shown in FIGS. 6 and 7, the back surface of the outer peripheral edge 43 of the seal member 40 faces the sealing surface 22 s of the opening 22 x peripheral edge of the door outer panel 22. In the state of contact, the seal member 40 is bent into a substantially L-shaped cross section, and the inner peripheral edge 44 of the seal member 40 is pushed into the opening 22x of the door outer panel 22. That is, the seal member 40 covers the periphery of the opening 22x of the door outer panel 22 and covers the opening edge 220x of the opening 22x. Next, in this state, the lamp housing 32 of the rear lamp unit 30 is housed in the recess 22k of the door outer panel 22, and the bottom portion 321b of the lamp housing 32 is fitted into the opening 22x of the door outer panel 22.
この状態で、図６、図７に示すように、シール部材４０は、外周縁４３がドアアウタパネル２２の開口部２２ｘ周縁のシール面２２ｓとランプハウジング３２のフランジ部３２３のシール面３２４とに挟持されるようになる。ここで、フランジ部３２３のシール面３２４には、突条３２４ｔが全周に亘って形成されているため、突条３２４ｔに押圧される外周縁４３の一部はシール部材４０の他の部分よりも強い押圧力を受けて大きく弾性変形する。また、シール部材４０の内周縁４４は、ドアアウタパネル２２の開口部２２ｘの開口エッヂ部２２０ｘとランプハウジング３２のハウジング本体部３２１のシール面３２１ｒとに挟持される。ここで、開口エッヂ部２２０ｘに押圧される内周縁４４の一部もシール部材４０の他の部分より強い押圧力を受けるため大きく弾性変形するようになる。このため、ランプハウジング３２の嵌め込み部は、前記シール部材４０の外周縁４３の部分と内周縁４４の部分とにより径方向において二ヶ所でシールされる。即ち、径方向において二重シール状態となる。この状態で、リヤランプユニット３０はドアアウタパネル２２にボルト（図示省略）止めされる。
このように、ランプハウジング３２とドアアウタパネル２２の開口部２２ｘ周縁間は、径方向において二重シール状態となるため、例えば、図４、図５に示すように、リヤランプユニット３０と装飾用パネル２４との隙間Ｓから試験的に高圧洗車時の水が吹き付けられた場合でも、図６、図７に示すように、その水（点線参照）がシール部分を通過し難くなり、ドアアウタパネル２２の開口部２２ｘの内側やランプハウジング３２のハウジング本体部３２１とフランジ部３２３との隙間部分Ｓｈに浸入しなくなる。また、車室内からの湿った空気がドアインナパネル２３のメンテナンス用の開口部２３ｈからドア本体部２１内に入り込んだ場合でもその湿った空気（一点鎖線参照）がシール部分で遮られてランプハウジング３２の隙間部分Ｓｈに浸入しなくなる。このため、リヤランプユニット３０のランプレンズ３４の曇り等が発生し難くなる。
即ち、ドアアウタパネル２２の開口エッヂ部２２０ｘとランプハウジング３２のフランジ部３２３の突条３２４ｔとが本発明の突部に相当する。 In this state, as shown in FIGS. 6 and 7, the sealingmember 40 has the outer peripheral edge 43 sandwiched between the sealing surface 22 s of the peripheral edge of the opening 22 x of the door outer panel 22 and the sealing surface 324 of the flange 323 of the lamp housing 32. Will come to be. Here, since the protrusion 324t is formed over the entire circumference on the seal surface 324 of the flange portion 323, a part of the outer peripheral edge 43 pressed against the protrusion 324t is more than the other part of the seal member 40. Even under strong pressure, it undergoes large elastic deformation. Further, the inner peripheral edge 44 of the seal member 40 is sandwiched between the opening edge portion 220 x of the opening portion 22 x of the door outer panel 22 and the seal surface 321 r of the housing main body portion 321 of the lamp housing 32. Here, a part of the inner peripheral edge 44 pressed against the opening edge portion 220x also receives a stronger pressing force than the other part of the seal member 40, so that it is greatly elastically deformed. For this reason, the fitting portion of the lamp housing 32 is sealed at two places in the radial direction by the outer peripheral edge 43 and the inner peripheral edge 44 of the seal member 40. That is, a double seal state is obtained in the radial direction. In this state, the rear lamp unit 30 is fixed to the door outer panel 22 with bolts (not shown).
Thus, since the gap between thelamp housing 32 and the periphery of the opening 22x of the door outer panel 22 is double sealed in the radial direction, for example, as shown in FIGS. 4 and 5, the rear lamp unit 30 and the decorative panel 24 are provided. 6 and FIG. 7, even when water at the time of high-pressure car wash is sprayed experimentally from the gap S, the water (see the dotted line) becomes difficult to pass through the seal portion, and the door outer panel 22 is opened. The inside of the portion 22x and the gap portion Sh between the housing main body portion 321 and the flange portion 323 of the lamp housing 32 do not enter. Further, even when damp air from the passenger compartment enters the door main body 21 through the maintenance opening 23h of the door inner panel 23, the damp air (see the alternate long and short dash line) is blocked by the seal portion, and the lamp housing 32 does not enter the gap portion Sh. For this reason, fogging of the lamp lens 34 of the rear lamp unit 30 hardly occurs.
That is, the openingedge portion 220x of the door outer panel 22 and the protrusion 324t of the flange portion 323 of the lamp housing 32 correspond to the protrusion of the present invention.
このように、ランプハウジング３２とドアアウタパネル２２の開口部２２ｘ周縁間は、径方向において二重シール状態となるため、例えば、図４、図５に示すように、リヤランプユニット３０と装飾用パネル２４との隙間Ｓから試験的に高圧洗車時の水が吹き付けられた場合でも、図６、図７に示すように、その水（点線参照）がシール部分を通過し難くなり、ドアアウタパネル２２の開口部２２ｘの内側やランプハウジング３２のハウジング本体部３２１とフランジ部３２３との隙間部分Ｓｈに浸入しなくなる。また、車室内からの湿った空気がドアインナパネル２３のメンテナンス用の開口部２３ｈからドア本体部２１内に入り込んだ場合でもその湿った空気（一点鎖線参照）がシール部分で遮られてランプハウジング３２の隙間部分Ｓｈに浸入しなくなる。このため、リヤランプユニット３０のランプレンズ３４の曇り等が発生し難くなる。
即ち、ドアアウタパネル２２の開口エッヂ部２２０ｘとランプハウジング３２のフランジ部３２３の突条３２４ｔとが本発明の突部に相当する。 In this state, as shown in FIGS. 6 and 7, the sealing
Thus, since the gap between the
That is, the opening
＜本実施形態に係るリヤランプユニット３０の嵌め込み部シール構造の長所＞
本実施形態に係るリヤランプユニット３０の嵌め込み部シール構造によると、シール部材４０の外周縁４３の周方向全体と内周縁４４の周方向全体とがランプハウジング３２の突条３２４ｔとドアアウタパネル２２の開口エッヂ部２２０ｘとによって、他の部分よりも強く押圧されて大きく弾性変形する。このため、ランプハウジング３２とドアアウタパネル２２の開口部２２ｘ周縁間は、シール部材４０の外周縁４３の一部と内周縁４４の一部とにより径方向において二ヶ所でシールされる。即ち、径方向において二重シール状態となる。したがって、従来の一重シール状態の場合と比較してシール性が格段に向上する。
さらに、一枚のシール部材４０で二重シールを行なえるため、さほどコストアップにならない。
また、ドアアウタパネル２２の開口エッヂ部２２０ｘをシール部材４０の内周縁４４を押圧する突部として使用できるため、ドアアウタパネル２２側に特別に突部を形成しなくてもよくなり、コストを抑えることができる。
また、シール部材４０の内周端は、ドアアウタパネル２２の開口部２２ｘを通過して、その開口部２２ｘの内側に入り込んでいるため、ドアアウタパネル２２の開口エッヂ部２２０ｘとランプハウジング３２のシール面３２１ｒ間にシール部材４０を挟持し易くなる。
また、シール部材４０は、外周縁４３と内周縁４４との間が断面略L字形状に曲げられている。即ち、シール部材４０の外周縁４３によるシール部分と内周縁４４によるシール部分とが直線上に並ばないため、仮に、洗浄水が外周縁４３側のシール部分を通過しても、その通過した洗浄水が直接的に内周縁４４側のシール部分に当たらなくなり、その洗浄水が内周縁４４側のシール部分を通過し難くなる。 <Advantages of fitting structure sealing structure ofrear lamp unit 30 according to this embodiment>
According to the fitting portion sealing structure of therear lamp unit 30 according to the present embodiment, the entire circumferential direction of the outer peripheral edge 43 of the sealing member 40 and the entire circumferential direction of the inner peripheral edge 44 are the openings of the protrusions 324t of the lamp housing 32 and the door outer panel 22. By the edge part 220x, it is pressed more strongly than the other part and is greatly elastically deformed. Therefore, the gap between the lamp housing 32 and the periphery of the opening 22x of the door outer panel 22 is sealed at two locations in the radial direction by a part of the outer peripheral edge 43 and a part of the inner peripheral edge 44 of the seal member 40. That is, a double seal state is obtained in the radial direction. Therefore, the sealing performance is remarkably improved as compared with the conventional single seal state.
Furthermore, since double sealing can be performed with one sealingmember 40, the cost does not increase much.
Moreover, since the openingedge part 220x of the door outer panel 22 can be used as a protrusion that presses the inner peripheral edge 44 of the seal member 40, it is not necessary to form a special protrusion on the door outer panel 22 side, thereby reducing costs. Can do.
Further, since the inner peripheral end of the sealingmember 40 passes through the opening 22x of the door outer panel 22 and enters the inside of the opening 22x, the opening edge 220x of the door outer panel 22 and the sealing surface of the lamp housing 32 It becomes easy to sandwich the sealing member 40 between 321r.
Further, theseal member 40 is bent between the outer peripheral edge 43 and the inner peripheral edge 44 into a substantially L-shaped cross section. That is, since the seal portion by the outer peripheral edge 43 of the seal member 40 and the seal portion by the inner peripheral edge 44 are not aligned in a straight line, even if the cleaning water passes through the seal portion on the outer peripheral edge 43 side, Water does not directly hit the seal portion on the inner peripheral edge 44 side, and the washing water hardly passes through the seal portion on the inner peripheral edge 44 side.
本実施形態に係るリヤランプユニット３０の嵌め込み部シール構造によると、シール部材４０の外周縁４３の周方向全体と内周縁４４の周方向全体とがランプハウジング３２の突条３２４ｔとドアアウタパネル２２の開口エッヂ部２２０ｘとによって、他の部分よりも強く押圧されて大きく弾性変形する。このため、ランプハウジング３２とドアアウタパネル２２の開口部２２ｘ周縁間は、シール部材４０の外周縁４３の一部と内周縁４４の一部とにより径方向において二ヶ所でシールされる。即ち、径方向において二重シール状態となる。したがって、従来の一重シール状態の場合と比較してシール性が格段に向上する。
さらに、一枚のシール部材４０で二重シールを行なえるため、さほどコストアップにならない。
また、ドアアウタパネル２２の開口エッヂ部２２０ｘをシール部材４０の内周縁４４を押圧する突部として使用できるため、ドアアウタパネル２２側に特別に突部を形成しなくてもよくなり、コストを抑えることができる。
また、シール部材４０の内周端は、ドアアウタパネル２２の開口部２２ｘを通過して、その開口部２２ｘの内側に入り込んでいるため、ドアアウタパネル２２の開口エッヂ部２２０ｘとランプハウジング３２のシール面３２１ｒ間にシール部材４０を挟持し易くなる。
また、シール部材４０は、外周縁４３と内周縁４４との間が断面略L字形状に曲げられている。即ち、シール部材４０の外周縁４３によるシール部分と内周縁４４によるシール部分とが直線上に並ばないため、仮に、洗浄水が外周縁４３側のシール部分を通過しても、その通過した洗浄水が直接的に内周縁４４側のシール部分に当たらなくなり、その洗浄水が内周縁４４側のシール部分を通過し難くなる。 <Advantages of fitting structure sealing structure of
