On the other hand, the mounting base sections are mounted in the vehicle body hood, so that alternation of slits 30, 40 becomes narrow or is completely closed.SELECTED DRAWING: Figure 8

Description

本発明は、車体の隙間を封止するシール部材に関する。 The present invention relates to a seal member for sealing a gap in a vehicle body.

自動車の車体に設けられる開口と、当該開口を開閉する蓋板に関し、蓋板を閉位置にした状態で、蓋板と開口縁の隙間をシールする構造として、従来、例えば特開平０５－０８５２８２号公報（特許文献１）に記載のものが知られている。特許文献１記載のシール構造は、乗用自動車の車体前部に設けられるエンジンルーム（車体開口部）と、エンジンルームを覆う開閉可能な蓋状のエンジンフード（ボンネットともいう）と、エンジンフード左縁・前縁・右縁に沿って連なって取付固定される帯状のシールとを有する。エンジンフードが閉位置にされると、シールは車体とエンジンフードに挟まれて、両者間の隙間を封止する。 Regarding an opening provided in an automobile body and a lid plate that opens and closes the opening, a conventional structure for sealing the gap between the lid plate and the edge of the opening when the lid plate is in the closed position is disclosed in Japanese Patent Application Laid-Open No. 05-085282, for example. The one described in the publication (Patent Document 1) is known. The seal structure described in Patent Document 1 includes an engine room (body opening) provided at the front of a passenger car, an engine hood (also referred to as a bonnet) in the form of an openable and closable lid that covers the engine room, and a left edge of the engine hood.・It has a band-shaped seal that is attached and fixed along the front edge and right edge. When the engine hood is in the closed position, the seal is sandwiched between the vehicle body and the engine hood, sealing the gap between the two.

特許文献１記載のエンジンフードは、車体の左縁から右縁まで広がる略矩形の板である。エンジンフード後縁はヒンジでエンジンルーム後縁に連結され、かかるヒンジによりエンジンフードは開閉可能である。エンジンルーム前縁には、ヘッドライトおよびフロントグリルが配置される。具体的にはヘッドライトは左右両側に配置され、フロントグリルは左右両側のヘッドライト間に配置される。エンジンフード前縁は、車体のフロントグリルおよびヘッドライトの形状に合わせて形成される。 The engine hood described in Patent Document 1 is a substantially rectangular plate that extends from the left edge to the right edge of the vehicle body. The rear edge of the engine hood is connected to the rear edge of the engine compartment by a hinge, and the hinge allows the engine hood to be opened and closed. The headlights and front grille are located at the front edge of the engine compartment. Specifically, the headlights are placed on both the left and right sides, and the front grill is placed between the left and right headlights. The leading edge of the engine hood is formed to match the shape of the vehicle's front grille and headlights.

特許文献１記載の自動車では、左ヘッドライトと、フロントグリルと、右ヘッドライトが、１列に整然と配列される。これに対応してエンジンフード前縁は、直線形状であるか、あるいは緩やかな弧を描くような略直線形状とされる。また帯状のシール部材は、長手方向いずれの位置にあっても断面形状一定とされる。 In the automobile described in Patent Document 1, the left headlight, the front grille, and the right headlight are arranged in an orderly line. Correspondingly, the front edge of the engine hood has a straight line shape or a substantially straight line shape that draws a gentle arc. Further, the band-shaped sealing member has a constant cross-sectional shape no matter where it is located in the longitudinal direction.

特開平０５－０８５２８２号公報Japanese Patent Application Publication No. 05-085282

エンジンフードは開位置にされると、エンジンフード下面がやや下向きで立ち上がる。シールの帯幅方向一側部（後側）はエンジンフード下面に固定されているが、シールの帯幅方向他側部（前側）はエンジンフード前縁に固定されてなく、帯幅方向一側部によって片持ち支持される。このため、シールの帯幅方向他側部は自重で下方へ垂れ下がってしまい、エンジンフード前縁の見栄えが悪くなってしまうという問題がある。 When the engine hood is in the open position, the bottom surface of the engine hood stands up slightly downward. One side (rear side) of the seal in the band width direction is fixed to the lower surface of the engine hood, but the other side (front side) of the seal in the band width direction is not fixed to the front edge of the engine hood, and is fixed to one side in the band width direction. Cantilevered by the section. Therefore, the other side of the seal in the band width direction hangs downward due to its own weight, resulting in a problem that the front edge of the engine hood looks unsightly.

かかる問題を解消するため、シールの帯幅方向一側部をエンジンフード下面に取り付けた状態で、シールの帯幅方向他側部がエンジンフード前縁を押し付けるよう、取り付け前のシール形状に見込みを設けておくことが考えられる。見込みとは、取り付けによる所定方向の弾性変形を見込んで、取り付け前の形状を所定方向とは反対方向に設定しておくことをいう。 In order to solve this problem, we designed the shape of the seal before installation so that while one side of the seal in the band width direction is attached to the underside of the engine hood, the other side of the seal in the band width direction presses against the leading edge of the engine hood. It may be possible to set one up. Expected means that the shape before installation is set in the opposite direction to the predetermined direction in anticipation of elastic deformation in the predetermined direction due to installation.

一方で、近年の車両デザインの発達により、エンジンフードの形状や、ヘッドライトの形状等が従来のような直線形状ではなくなっている。これに呼応して帯状シールも、長手方向位置に関して断面形状が相違し、複雑な形状が要求され、帯状シールの長手方向の全ての部位に見込みを設けることが困難な場合がある。この場合、帯状シールの長手方向の或る一部（例えば押出部）には見込みを設け、他の一部（例えば型部）には見込みを設けず、或る一部と他の一部の境界にスリットを設けることになる。かかる場合であっても帯状シールは、長手方向全体において、エンジンフード前縁を途切れることなく覆うよう、見栄え良く取付固定されることが要求される。 On the other hand, due to recent developments in vehicle design, the shape of engine hoods, headlights, etc. are no longer linear as in the past. Correspondingly, the band-shaped seal also has a different cross-sectional shape with respect to its longitudinal position, and is required to have a complicated shape, so that it may be difficult to provide a prospect in all longitudinal parts of the band-shaped seal. In this case, a certain part (for example, the extrusion part) in the longitudinal direction of the band-shaped seal is provided with a prospect, and another part (for example, the mold part) is not provided with a prospect, and a certain part and another part are separated. A slit will be provided at the border. Even in such a case, the belt-shaped seal is required to be installed and fixed in a good-looking manner so as to cover the leading edge of the engine hood seamlessly in the entire longitudinal direction.

本発明は、上述の実情に鑑み、見込みが設けられる長手方向領域および見込みが設けられない長手方向領域の双方を備えるシール部材であっても、エンジンフード前縁を途切れることなくカバーすることができ、スリット越しにエンジンフード下面が見えてしまう事のないシール部材を提供することを目的とする。 In view of the above-mentioned circumstances, the present invention makes it possible to cover the front edge of the engine hood without interruption even if the sealing member includes both a longitudinal region in which a projection is provided and a longitudinal region in which a projection is not provided. To provide a sealing member that does not allow the underside of an engine hood to be seen through the slit.

この目的のため本発明によるシール部材は、車体開口の開口縁に沿って延び、開口縁および車体開口を覆う車体フードとの隙間を封止する帯状のシール部材であって、シール部材の長手方向第１領域と長手方向第２領域の境界のうち帯幅方向一側部には、スリットが形成され、シール部材の帯幅方向一側部は、車体フードの下面に取り付けられる前の状態で、スリットにおいて帯厚方向に互い違いをなすよう互いに離間し、車体フードの下面に取り付けられた後の状態で、互い違いが狭くなるか、あるいは互い違いが完全に閉じ、シール部材の帯幅方向他側部が、帯幅方向一側部に片持ち支持されつつ車体フードの前縁に接触し、シール部材の長手方向第１領域のうち帯幅方向他側部が、変形することなく、あるいは相対的に小さく弾性変形し、シール部材の長手方向第２領域のうち帯幅方向他側部が、長手方向第１領域のうち帯幅方向他側部よりも相対的に大きく弾性変形するよう構成される。 For this purpose, the sealing member according to the present invention is a band-shaped sealing member that extends along the opening edge of a vehicle body opening and seals a gap between the opening edge and the vehicle body hood that covers the vehicle body opening, and the sealing member is a belt-shaped sealing member that extends along the opening edge of the vehicle body opening and seals a gap between the opening edge and the vehicle body hood that covers the vehicle body opening. A slit is formed at one side in the belt width direction of the boundary between the first region and the second longitudinal region, and one side in the belt width direction of the seal member is in a state before being attached to the lower surface of the vehicle hood. The slits are spaced apart from each other so as to be staggered in the band thickness direction, and after being attached to the underside of the car body hood, the staggers become narrower or the staggers are completely closed, and the other side of the seal member in the band width direction , is cantilevered on one side in the band width direction and contacts the front edge of the vehicle body hood, and the other side in the band width direction of the first region in the longitudinal direction of the seal member is not deformed or is relatively small. The sealing member is configured to be elastically deformed, and the other side in the band width direction of the second longitudinal region of the seal member is relatively more elastically deformed than the other side in the band width direction of the first longitudinal region.

かかる本発明によれば、車体フードが起立して開位置にある場合に、シール部材の一部が垂れ下がって車体フード前縁から離れることがなく、またスリット越しに車体フード下面が見えてしまうことがなく、車体フードはシール部材によって見栄え良くカバーされる。 According to the present invention, when the vehicle body hood is upright and in the open position, a part of the sealing member does not hang down and separate from the front edge of the vehicle body hood, and the lower surface of the vehicle body hood is not visible through the slit. The vehicle body hood is covered with a sealing member for a good appearance.

スリットの延在方向と、スリットの形状は特に限定されない。本発明の一局面として、シール部材の長手方向位置に関し、スリットとシール部材表面の接続位置と、スリットとシール部材裏面の接続位置が異なる。かかる局面によれば、シール部材を帯厚方向にみて、スリットの裏側が見えなくなり、スリット越しに車体フード下面が見えてしまうことがない。本発明の好ましい局面として、スリットを構成するスリット面が、シール部材の帯厚方向に対して傾斜する。ここでスリット面は平面である。あるいは他の局面としてスリット面は帯厚方向と平行であってもよい。 The extending direction of the slit and the shape of the slit are not particularly limited. As one aspect of the present invention, regarding the longitudinal position of the seal member, the connection position between the slit and the seal member surface is different from the connection position between the slit and the seal member back surface. According to this aspect, when the sealing member is viewed in the band thickness direction, the back side of the slit is no longer visible, and the lower surface of the vehicle body hood is not seen through the slit. In a preferred aspect of the present invention, the slit surface constituting the slit is inclined with respect to the thickness direction of the sealing member. Here, the slit surface is a flat surface. Alternatively, in another aspect, the slit plane may be parallel to the belt thickness direction.

本発明の他の局面として、シール部材の長手方向位置に関し、スリットとシール部材表面の接続位置と、スリットとシール部材裏面の接続位置が同じであってもよい。例えば、スリットを構成するスリット面が、シール部材の帯厚方向と平行な平面である。ここでスリット面は、例えば平面である。 As another aspect of the present invention, regarding the longitudinal position of the seal member, the connection position between the slit and the seal member surface may be the same as the connection position between the slit and the seal member back surface. For example, the slit surface constituting the slit is a plane parallel to the band thickness direction of the sealing member. Here, the slit surface is, for example, a flat surface.

本発明の一局面として、シール部材のうち、長手方向第１領域は型成形部材であり、長手方向第２領域は押出成形部材であり、両部材が互いに接合される。かかる局面によれば、長尺なシール部材を効率良く製造することができる。他の局面として、シール部材のうち、長手方向第１領域と、長手方向第２領域のうちスリットが形成される部分は、型成形部材であり、長手方向第２領域の残りの部分は押出成形部材であり、両部材が互いに接合される。かかる局面によれば、スリットを型成型によって精度良く効率的に製造することができる。 In one aspect of the present invention, the first longitudinal region of the seal member is a molded member, the second longitudinal region is an extruded member, and both members are joined to each other. According to this aspect, a long sealing member can be efficiently manufactured. In another aspect, of the sealing member, the portions of the first longitudinal region and the second longitudinal region where the slits are formed are molded members, and the remaining portion of the second longitudinal region is extrusion molded. parts, and both parts are joined to each other. According to this aspect, the slit can be manufactured accurately and efficiently by molding.

このように本発明によれば、車体フードに取り付ける帯状のシール部材が、見込みが設けられていない長手方向第１領域と、車体フード前縁を押圧するよう見込みが設けられる長手方向第２領域と、両領域の境界に設けられて見込みの差分を吸収するスリットとを備える場合に、車体フードが起立してシール部材の姿勢が変化しても、スリット越しに車体フード下面が見えない。 As described above, according to the present invention, the band-shaped sealing member attached to the vehicle body hood has a first region in the longitudinal direction in which the projection is not provided and a second region in the longitudinal direction in which the projection is provided so as to press the front edge of the vehicle body hood. In the case where a slit is provided at the boundary between the two areas and absorbs the difference in potential, the lower surface of the vehicle hood cannot be seen through the slit even if the vehicle hood stands up and the attitude of the sealing member changes.

以下、本発明の実施の形態を、図面に基づき詳細に説明する。図１は、本発明のシール部材が取付固定される自動車のフードおよび車体前部を示す模式的な斜視図である。本明細書中、左右とは車幅方向をいい、前後とは車両前方および後方をいう。車体１００の前部にはエンジン、あるいは電気自動車の電気部品、あるいは荷物等が収容されるルーム１０１が区画形成される。ルーム１０１は少なくとも上側が開口する。かかる車体開口は、左車体パネル１０３ｍと右車体パネル１０３ｎとフロントグリル１０４とダッシュパネル１０５で区画される。また車体開口の前側左右には、ヘッドライト１０６がそれぞれ配置される。車体開口の前側の開口縁１０１ａは、車幅方向中央領域のフロントグリル１０４と、左右のヘッドライト１０６で構成される。 Hereinafter, embodiments of the present invention will be described in detail based on the drawings. FIG. 1 is a schematic perspective view showing the hood and front part of an automobile to which a sealing member of the present invention is attached and fixed. In this specification, left and right refers to the vehicle width direction, and front and rear refers to the front and rear of the vehicle. A room 101 is formed at the front of the vehicle body 100 to accommodate an engine, electrical parts of an electric vehicle, luggage, and the like. Room 101 is open at least on the upper side. The vehicle body opening is defined by a left body panel 103m, a right body panel 103n, a front grill 104, and a dash panel 105. Furthermore, headlights 106 are arranged on the front left and right sides of the vehicle body opening, respectively. The front opening edge 101a of the vehicle body opening is composed of a front grille 104 in the center area in the vehicle width direction, and left and right headlights 106.

車体開口はフード１０２によって開閉可能とされる。図１および図２はフード１０２の開状態（開位置ともいう）を示す。フード１０２の後縁１０２ｅは、ヒンジ１０７で車体１００に連結される。図１に示すように車体１００が水平な路面に駐車された状態において、ヒンジ１０７は、水平面に対して９０°未満、例えば０°～８０°の範囲で、フード１０２の開位置まで角度変化を許容する。フード１０２のフード前縁１０２ｄにはシール部材１が取り付けられる。 The vehicle body opening can be opened and closed by a hood 102. 1 and 2 show the hood 102 in an open state (also referred to as an open position). A rear edge 102e of the hood 102 is connected to the vehicle body 100 by a hinge 107. When the vehicle body 100 is parked on a horizontal road surface as shown in FIG. Allow. A sealing member 1 is attached to the front edge 102d of the hood 102.

図２は、図１中のフード１０２のフード前縁１０２ｄを拡大して示す模式的な斜視図である。図３および図４は、フード１０２を閉じた状態でのフード前縁１０２ｄおよび開口縁１０１ａを拡大して示す模式的な断面図であり、図２に表されるシール部材１の長手方向第２領域Ｓａ中III－IIIと、長手方向第１領域Ｆａ中IV－IVとでシール部材１およびフード１０２を切断し、各切断面を矢の方向に見た状態を表す。 FIG. 2 is a schematic perspective view showing an enlarged front edge 102d of the hood 102 in FIG. 3 and 4 are schematic cross-sectional views showing the hood front edge 102d and the opening edge 101a in an enlarged manner when the hood 102 is closed. The seal member 1 and the hood 102 are cut at III-III in the region Sa and IV-IV in the first longitudinal region Fa, and each cut surface is shown in the direction of the arrow.

フード１０２は、通常、図３、図４の断面図に示すように、下側の閉位置にされ、略水平姿勢、あるいはフード前縁１０２ｄがフード後縁１０２ｅよりも低い傾倒姿勢でルーム１０１を覆う。かかる閉位置でフード１０２のフード前縁１０２ｄは、左右のヘッドライト１０６と、車幅方向中央領域のフロントグリル１０４に沿うようにされ、これらとの間で隙間Ｓを構成する。フード１０２は、図１および図２に示すように上側の開位置にされると、フード前縁１０２ｄがフード後縁１０２ｅよりも高くなるよう、フード１０２はヒンジ１０７を中心として回動起立し、ルーム１０１を露出させる。 Usually, the hood 102 is placed in the lower closed position, as shown in the cross-sectional views of FIGS. 3 and 4, and the room 101 is placed in a substantially horizontal position or in a tilted position in which the front edge 102d of the hood is lower than the rear edge 102e. cover. In the closed position, the front edge 102d of the hood 102 is aligned with the left and right headlights 106 and the front grille 104 in the center area in the vehicle width direction, and forms a gap S therebetween. When the hood 102 is placed in the upper open position as shown in FIGS. 1 and 2, the hood 102 rotates and stands up about the hinge 107 so that the front edge 102d of the hood is higher than the rear edge 102e of the hood. Room 101 is exposed.

フード１０２は、通常、図３、図４の断面図に示すように、上側で広がるフード本体（アウターパネル）１０２ａと、フード本体１０２ａの下側に固定されるインナーパネル１０２ｂを有する。便宜上、インナーパネル１０２ｂを単にフード下面ともいう。またシール部材１をフード１０２に取り付けた際に、シール部材１のルーム１０１側を表側といい、シール部材１のフード１０２側を裏側という。 The hood 102 normally has a hood main body (outer panel) 102a that widens at the upper side and an inner panel 102b fixed to the lower side of the hood main body 102a, as shown in the cross-sectional views of FIGS. 3 and 4. For convenience, the inner panel 102b is also simply referred to as the lower surface of the hood. Further, when the seal member 1 is attached to the hood 102, the room 101 side of the seal member 1 is called the front side, and the hood 102 side of the seal member 1 is called the back side.

シール部材１はフード１０２のフード前縁１０２ｄ付近に沿って延びる帯状部材であり、フード１０２の車幅方向に延びる。以下の説明では、図１および図２に示すようにシール部材１が延びる方向を長手方向ともいう。シール部材１は帯幅方向を前後方向にしてフード１０２のインナーパネル１０２ｂ（フード下面）に取付固定される。具体的には、シール部材１の帯幅方向一側部になる後縁部に、複数の貫通孔１１ａが形成され、各貫通孔１１ａにクリップ３１が通されて、各クリップ３１はフード１０２の下側に設けられるインナーパネル１０２ｂの対応箇所に形成されるパネル貫通孔１０２ｃに嵌合する。以下の説明では、後縁部を、取付基部１１，２１，２６ともいう。本明細書では説明の便宜上、フード１０２が図２に示す起立姿勢にされていても、シール部材１の帯幅方向を前後方向という場合がある。 The seal member 1 is a band-shaped member that extends near the front edge 102d of the hood 102, and extends in the vehicle width direction of the hood 102. In the following description, the direction in which the seal member 1 extends as shown in FIGS. 1 and 2 will also be referred to as the longitudinal direction. The sealing member 1 is attached and fixed to the inner panel 102b (lower surface of the hood) of the hood 102 with the band width direction being the front-rear direction. Specifically, a plurality of through holes 11a are formed in the rear edge of the sealing member 1 on one side in the band width direction, and a clip 31 is passed through each through hole 11a, and each clip 31 is inserted into the hood 102. It fits into a panel through hole 102c formed at a corresponding location of an inner panel 102b provided on the lower side. In the following description, the rear edge portions are also referred to as attachment bases 11, 21, and 26. In this specification, for convenience of explanation, even if the hood 102 is in the upright position shown in FIG. 2, the band width direction of the seal member 1 may be referred to as the front-rear direction.

シール部材１の帯幅方向他側部になる前縁部は、上述した後縁部に片持ち支持される。図３および図４を参照して、前縁部は、シール基部１３，２３，２８、シールリップ１４，２４，２９を構成する。シールリップ１４，２４，２９は開口縁１０１ａに弾接する。 The front edge of the seal member 1 on the other side in the band width direction is supported in a cantilever manner by the above-mentioned rear edge. Referring to FIGS. 3 and 4, the front edge portions constitute seal bases 13, 23, 28 and seal lips 14, 24, 29. The seal lips 14, 24, 29 come into elastic contact with the opening edge 101a.

図１および図２を参照してシール部材１の後縁部には、スリット３０，４０が設けられる。スリット３０，４０の延在方向は、シール部材１の長手方向（車幅方向）と直交するか、あるいは略直交する。スリット４０は、シール部材１のうち、長手方向一方側の第１領域Ｆａと、長手方向他方側の第２領域Ｓａとの境界に設けられる。スリット３０についても同様であり、説明の重複を避けるために以下、スリット４０につき主に説明する。第１実施形態では、車幅方向両端部を長手方向第１領域Ｆａとし、車幅方向中央領域を長手方向第２領域Ｓａとする。図４に示すように長手方向第１領域Ｆａはヘッドライト１０６と隣接する。図３に示すように長手方向第２領域Ｓａはフロントグリル１０４と隣接する。 Referring to FIGS. 1 and 2, slits 30 and 40 are provided at the rear edge of the seal member 1. As shown in FIGS. The extending direction of the slits 30 and 40 is perpendicular or substantially perpendicular to the longitudinal direction (vehicle width direction) of the seal member 1. The slit 40 is provided at the boundary between the first area Fa on one longitudinal side of the sealing member 1 and the second area Sa on the other longitudinal side. The same applies to the slit 30, and in order to avoid duplication of explanation, the slit 40 will be mainly explained below. In the first embodiment, both end portions in the vehicle width direction are defined as a first longitudinal region Fa, and the central region in the vehicle width direction is defined as a second longitudinal region Sa. As shown in FIG. 4, the first region Fa in the longitudinal direction is adjacent to the headlight 106. As shown in FIG.

図５を参照して、第１領域Ｆａ中、帯幅方向一側から他側へ向かって、取付基部２１、接続部２２、シール基部２３、シールリップ２４が連続する。取付基部２１はシール部材１の帯幅方向一側部であり、前述した取付用の貫通孔１１ａが設けられる。図４を参照して、シール部材１の両面のうち、取付基部２１がインナーパネル１０２ｂに取付固定されることによってインナーパネル１０２ｂに接触する面をシール部材１の裏面ともいう。反対に、ルーム１０１に臨む面を表面ともいう。図１に示すようにフード１０２が開位置にされると、シール部材１の表面が露出する。 Referring to FIG. 5, in the first region Fa, the attachment base 21, the connecting portion 22, the seal base 23, and the seal lip 24 are continuous from one side in the band width direction to the other side. The mounting base 21 is one side of the seal member 1 in the band width direction, and is provided with the above-described mounting through hole 11a. Referring to FIG. 4, of both surfaces of the seal member 1, the surface that comes into contact with the inner panel 102b when the mounting base 21 is attached and fixed to the inner panel 102b is also referred to as the back surface of the seal member 1. Conversely, the surface facing room 101 is also referred to as the front surface. When the hood 102 is placed in the open position as shown in FIG. 1, the surface of the seal member 1 is exposed.

図３を参考して、第２領域Ｓａも第１領域Ｆａと同様であり、帯幅方向一側から他側へ向かって、取付基部１１、接続部１２、シール基部１３、シールリップ１４が連続する。 Referring to FIG. 3, the second area Sa is also similar to the first area Fa, and the mounting base 11, the connecting portion 12, the seal base 13, and the seal lip 14 are continuous from one side to the other side in the band width direction. do.

第２領域Ｓａには、シール基部１３を弾性変形させてフード１０２に接触させるための見込みが設けられる。取付基部１１，２６がフード１０２に取り付けられることによって、図３に仮想線で示すようにシール基部１３，２８およびシールリップ１４，２９は、仮想線で表される取付前の原形状態における原位置から、実線で表される取付後位置に弾性変形する。かかる見込みによって、シール基部１３，２８の前縁部１３ａ，２８ａはある程度大きな面圧でフード前縁１０２ｄを押圧する。かかる見込みにより、フード１０２が図１および図２に示す開位置に起立してフード前縁１０２ｄが上向きとされつつフード下面（インナーパネル１０２ｂ）がやや下方へ指向しても、シール基部１３，２８が垂れ下がってフード前縁１０２ｄとシール基部１３，２８の前縁部１３ａ，２８ａの間に隙間が発生することがない。第１実施形態によれば、フード前縁１０２ｄは第２領域Ｓａによって見栄え良くカバーされる。 In the second region Sa, a portion is provided for elastically deforming the seal base 13 and bringing it into contact with the hood 102. By attaching the mounting bases 11 and 26 to the hood 102, the seal bases 13 and 28 and the seal lips 14 and 29 are in their original positions in the original state before installation, as shown by the phantom lines in FIG. From there, it is elastically deformed to the post-installation position shown by the solid line. Due to this expectation, the front edges 13a, 28a of the seal bases 13, 28 press the hood front edge 102d with a relatively large surface pressure. Due to this expectation, even if the hood 102 is erected in the open position shown in FIGS. 1 and 2, with the hood front edge 102d facing upward and the hood lower surface (inner panel 102b) directed slightly downward, the seal bases 13, 28 There is no possibility that a gap will be created between the front edge 102d of the hood and the front edges 13a, 28a of the seal bases 13, 28 due to drooping. According to the first embodiment, the hood front edge 102d is covered by the second region Sa with good appearance.

一方、第１領域Ｆａには見込みが設けられない（図４）。前述したように取付基部２１がフード１０２に取り付けられることによって、図４に示すようにシール基部２３は、殆ど弾性変形しないか、僅かに弾性変形する。つまりシール基部２３は、フード前縁１０２ｄを押圧しないか、相対的に小さな面圧でフード前縁１０２ｄを押圧する。 On the other hand, no prospect is provided in the first area Fa (FIG. 4). By attaching the attachment base 21 to the hood 102 as described above, the seal base 23 hardly or only slightly undergoes elastic deformation, as shown in FIG. In other words, the seal base 23 either does not press the hood front edge 102d or presses the hood front edge 102d with a relatively small surface pressure.

上述した垂れ下がり防止のため第１領域Ｆａは、第２領域Ｓａと比較してクリップ３１の数を増やしたり、図示は省略するが両面接着テープや接着剤等でインナーパネル１０２ｂに取付固定されるとよい。第１領域Ｆａに含まれる取付基部２１，２６およびシール基部２３，２８は、例えばＥＰＤＭソリッドゴム等の非発泡ゴム、他の耐候性ゴム、あるいはＴＰＯ等の熱可塑性エラストマーからなる。 In order to prevent the above-mentioned hanging, the first area Fa may have an increased number of clips 31 compared to the second area Sa, or may be attached and fixed to the inner panel 102b with double-sided adhesive tape, adhesive, etc. (not shown). good. The attachment bases 21, 26 and the seal bases 23, 28 included in the first area Fa are made of, for example, non-foamed rubber such as EPDM solid rubber, other weather-resistant rubber, or thermoplastic elastomer such as TPO.

第２領域Ｓａも、第１領域Ｆａと同程度の弾性を持つ各種ゴム又は熱可塑性樹脂からなる。 The second region Sa is also made of various rubbers or thermoplastic resins having the same degree of elasticity as the first region Fa.

第１領域Ｆａに含まれるシールリップ２４，２９は、上述した第１領域Ｆａの他の部分と同じ材料で形成されるか、あるいはＥＰＤＭスポンジゴム等の発泡ゴム、または発泡ＴＰＯや軟質ＴＰＯ等で形成されてもよい。第２領域Ｓａに含まれるシールリップ１４も、上述した第１領域Ｆａに含まれるシールリップ２４，２９と同程度の弾性を持つ材料で形成される。 The seal lips 24 and 29 included in the first area Fa are made of the same material as the other parts of the first area Fa described above, or are made of foamed rubber such as EPDM sponge rubber, foamed TPO, soft TPO, etc. may be formed. The seal lip 14 included in the second area Sa is also formed of a material having the same degree of elasticity as the seal lips 24 and 29 included in the first area Fa described above.

説明を図５に戻すと、スリット４０は、シール部材１の帯幅方向一側部を、取付基部２１と取付基部２６に分割する。取付基部２６と接続部２７とシール基部２８とリップシール２９は、第２領域Ｓａに含まれる。接続部２７とシール基部２８とシールリップ２９はそれぞれ、接続部１２，２２間、シール基部１３，２３間、シールリップ１４，２４間にあって両者を結合する。 Returning to FIG. 5, the slit 40 divides one side of the seal member 1 in the band width direction into the mounting base 21 and the mounting base 26. The attachment base 26, the connection portion 27, the seal base 28, and the lip seal 29 are included in the second region Sa. The connecting portion 27, the seal base 28, and the seal lip 29 are respectively located between the connecting portions 12 and 22, between the seal base portions 13 and 23, and between the seal lips 14 and 24, and connect them.

図５中、一点鎖線で示すように取付基部２１と取付基部２６は不揃いであり、後方へ向かうにつれて両者の段差が大きくなる。取付基部２１と取付基部２６の後端同士は、図６に示すように帯厚方向に互い違い寸法Ｄをなす。シールリップ２９は、シール部材１の帯幅方向他側部（スリット４０とは反対側の側部）にあって、帯幅方向一側へ折り返し形状に成形される。シールリップ２９は、シール部材１の表側にあって、シール基部２８に重なるよう配置される。シール基部２８は、シール部材１の帯幅方向他側部にあって、接続部２７を介して、取付基部２６と板状に整列し、段差が目立たなくされる。 In FIG. 5, as shown by the dashed line, the mounting base 21 and the mounting base 26 are not aligned, and the difference in level between them increases toward the rear. The rear ends of the attachment base 21 and the attachment base 26 have an alternating dimension D in the band thickness direction, as shown in FIG. The seal lip 29 is located on the other side of the sealing member 1 in the band width direction (the side opposite to the slit 40) and is formed into a shape folded back toward one side in the band width direction. The seal lip 29 is located on the front side of the seal member 1 and is arranged to overlap the seal base 28. The seal base 28 is located on the other side of the seal member 1 in the band width direction, and is aligned in a plate shape with the mounting base 26 via the connecting portion 27, so that the difference in level is made inconspicuous.

シール部材１は、フード１０２から取り外された状態（取付前）で、図７に示すようにスリット４０にて帯厚方向にずれている。すなわち、第１領域Ｆａの取付基部２１と、第２領域Ｓａの取付基部２６は段違いにされる。換言すると取付基部２１からみてシール基部２３は、見込みが設けられていない（図４参照）。これに対し取付基部２６からみてシール基部２８は、見込みが設けられている（図３参照）。 When the seal member 1 is removed from the hood 102 (before being attached), the seal member 1 is shifted in the band thickness direction at the slit 40, as shown in FIG. That is, the mounting base 21 in the first area Fa and the mounting base 26 in the second area Sa are at different levels. In other words, when viewed from the mounting base 21, the seal base 23 has no projection (see FIG. 4). On the other hand, when viewed from the mounting base 26, the seal base 28 is provided with an opening (see FIG. 3).

シール部材１がフード１０２（図３および図４）に取り付けられた後、取付基部２６は矢Ｂ（図７）に示すようにスリット４０を狭くする方向に回動変位して、見込みの弾性変形を発揮する。取付基部１１も同様である。ここで附言すると矢Ｂは、図３中、前縁部１３ａ，２８ａが仮想線位置から実線位置へ弾性変形することに対応する。より詳細には、図３は、見込みを入れたシール部材１の取付基部１１，２６を、フード１０２に先に取り付けた状態で、シール部材１の前縁部１３ａ，２８ａがどのように弾性変形するかを模式的に示した図である。 After the sealing member 1 is attached to the hood 102 (FIGS. 3 and 4), the mounting base 26 is rotationally displaced in the direction of narrowing the slit 40 as shown by arrow B (FIG. 7), thereby causing the expected elastic deformation. demonstrate. The same applies to the mounting base 11. It should be noted here that arrow B corresponds to elastic deformation of the front edges 13a, 28a from the imaginary line position to the solid line position in FIG. 3. More specifically, FIG. 3 shows how the front edges 13a, 28a of the seal member 1 are elastically deformed when the mounting bases 11, 26 of the seal member 1 are first attached to the hood 102. FIG.

図８および図９はシール部材１をフード１０２に取り付けた状態（取付後）を示す図であって、図８がシール部材１の表面を表し、取付基部１１，２１，２６の表面に対して略垂直な方向で見た状態を表す。（図７の矢ＶＩＩＩの方向にみた状態を表す）、図９はシール部材１を帯幅方向一側から他側に向かってみた状態を表す。参考のため図８には、取付基部２６，１１後端の取付前位置を仮想線で表す。なお矢ＶＩＩＩは、略平板状に連なる取付基部２６と接続部２７とシール基部２８に対し直角方向を表す。 8 and 9 are views showing the state in which the seal member 1 is attached to the hood 102 (after attachment), and FIG. 8 shows the surface of the seal member 1, and the surface of the attachment base 11, 21, 26 is Represents the state viewed in a substantially vertical direction. (Representing the state seen in the direction of arrow VIII in FIG. 7), FIG. 9 shows the state of the sealing member 1 seen from one side in the band width direction to the other side. For reference, in FIG. 8, the pre-installation position of the rear ends of the mounting bases 26, 11 is shown by imaginary lines. Note that arrow VIII represents a direction perpendicular to the mounting base 26, the connecting portion 27, and the seal base 28 that are connected in a substantially flat plate shape.

第２領域Ｓａに関し、図７に示すように取付基部２６が矢Ｂのように接続部２７を回動中心として相対移動し、シール部材１が折れるように弾性変形すると、取付基部２６は取付基部２１と揃うようになるまで角度変化し、見かけ上の帯幅寸法が僅かに短縮する。取付基部１１も同様である。スリット４０が狭くなる。 Regarding the second region Sa, as shown in FIG. 7, when the mounting base 26 moves relatively around the connecting portion 27 as shown by arrow B and elastically deforms so as to break the seal member 1, the mounting base 26 The angle changes until it becomes aligned with 21, and the apparent band width dimension is slightly shortened. The same applies to the mounting base 11. The slit 40 becomes narrower.

図６と図９を対比して、シール部材１がフード下面であるインナーパネル１０２ｂに取り付けられることによって、スリット４０は取付前よりも狭くなっていることが理解される（互い違い寸法Ｄが小さくなる）。図９中、第１実施形態のスリット４０は、互いに対向する１対の平面である。取付後のスリット４０のスリット幅Ｌ１は、互い違い寸法Ｄよりも狭く、例えば０．６ｍｍあるいは０．６ｍｍ以下の所定値である。なお変形例として、Ｌ１＝０、つまりスリット４０は完全に閉じるものであってもよい。 Comparing FIG. 6 and FIG. 9, it can be seen that by attaching the seal member 1 to the inner panel 102b, which is the lower surface of the hood, the slit 40 becomes narrower than before attachment (the alternating dimension D becomes smaller). ). In FIG. 9, the slits 40 of the first embodiment are a pair of planes facing each other. The slit width L1 of the slit 40 after attachment is narrower than the alternating dimension D, and is, for example, 0.6 mm or a predetermined value of 0.6 mm or less. Note that as a modification, L1=0, that is, the slit 40 may be completely closed.

図８は、シール部材１を表側から裏側へ帯厚方向にみたものである。図８を参照して、スリット４０のスリット面が僅かに視認されるが、インナーパネル１０２ｂはスリット４０越しに見えない。ここで、スリット幅Ｌ１を０．６ｍｍより大きくする場合、シール部材１の表面および裏面に対するスリット面Ｈ１，Ｈ２（図６）の傾斜角度を３０°よりも小さい角度に設定し、スリット面Ｈ１，Ｈ２（図６）を十分広くしてスリット４０（図８）越しに裏側のインナーパネル１０２ｂが視認されないようにする必要がある。そうすると、スリット面Ｈ１，Ｈ２がシール部材１の表面および裏面に沿ってしまい、スリット面Ｈ１，Ｈ２のそれぞれの先端部形状が鋭利になりすぎて、金型でスリット４０を形状成形する際に型落ちする（形状成形できない）等の不具合が発生する可能性が高くなり、好ましくない。 FIG. 8 shows the seal member 1 viewed from the front side to the back side in the band thickness direction. Referring to FIG. 8, although the slit surface of slit 40 is slightly visible, inner panel 102b is not visible through slit 40. Here, when making the slit width L1 larger than 0.6 mm, the inclination angle of the slit surfaces H1, H2 (FIG. 6) with respect to the front and back surfaces of the sealing member 1 is set to an angle smaller than 30°, and the slit surfaces H1, It is necessary to make H2 (FIG. 6) sufficiently wide so that the inner panel 102b on the back side is not visible through the slit 40 (FIG. 8). In this case, the slit surfaces H1 and H2 end up along the front and back surfaces of the sealing member 1, and the tip end shapes of the slit surfaces H1 and H2 become too sharp. This is undesirable because it increases the possibility of problems such as falling (unable to form a shape).

図６を参照して、第１実施形態のスリット４０は、互いに対向する１対のスリット面Ｈ１，Ｈ２で構成され、各スリット面は傾斜面である。ここでいう傾斜面とは、少なくともシール部材１の長手方向と直交せず、シール部材１の帯厚方向と不平行で傾斜する面をいう。第１実施形態のスリット面は、帯幅方向と平行であるが、帯厚方向かつ長手方向に対して３０°～６０°の範囲で傾斜する。 Referring to FIG. 6, the slit 40 of the first embodiment is composed of a pair of slit surfaces H1 and H2 that face each other, and each slit surface is an inclined surface. The slanted surface herein refers to a surface that is not perpendicular to the longitudinal direction of the seal member 1, is nonparallel to the band thickness direction of the seal member 1, and is inclined. The slit plane of the first embodiment is parallel to the band width direction, but is inclined at an angle of 30° to 60° with respect to the band thickness direction and longitudinal direction.

図６を参照して、シール部材１の長手方向に関し、スリット面Ｈ１，Ｈ２の長手方向寸法につき附言すると、第１領域Ｆａ側のスリット面Ｈ１とシール部材１表面の接続位置は第２領域Ｓａに近い長手方向位置とされ、スリット面Ｈ１とシール部材１裏面の接続位置は第２領域Ｓａから遠い長手方向位置とされる。また、第２領域Ｓａ側のスリット面Ｈ２とシール部材表面の接続位置は第１領域Ｆａから遠い長手方向位置とされ、スリット面Ｈ２とシール部材裏面の接続位置は第１領域Ｆａに近い長手方向位置とされる。スリット面Ｈ１，Ｈ２の長手方向寸法は、後述するスリット幅Ｌ１よりも大きい。スリット３０の形状および構造は、シール部材１の長手方向中央で折り返すようにして、スリット４０とは左右対称にされる。 Referring to FIG. 6, regarding the longitudinal dimensions of the slit surfaces H1 and H2 of the seal member 1, the connection position between the slit surface H1 on the side of the first region Fa and the surface of the seal member 1 is in the second region. The connection position between the slit surface H1 and the back surface of the sealing member 1 is located at a longitudinal position close to the second area Sa. Further, the connection position between the slit surface H2 on the second area Sa side and the surface of the sealing member is in the longitudinal direction far from the first area Fa, and the connection position between the slit surface H2 and the back surface of the sealing member is in the longitudinal direction close to the first area Fa. position. The longitudinal dimensions of the slit surfaces H1 and H2 are larger than the slit width L1, which will be described later. The shape and structure of the slit 30 are symmetrical to the slit 40 by being folded back at the center in the longitudinal direction of the sealing member 1.

シール部材１の取付に際し、図６に示すように、見込み（図３仮想線）を有する第２領域Ｓａがインナーパネル１０２ｂに近い側にセットされ、見込みを有さない第１領域Ｆａがインナーパネル１０２ｂから遠い側にセットされる。また第２領域Ｓａに形成されるスリット面Ｈ２が、表向きとなるよう傾斜し、断面先細となる縁でシール部材１の第２領域Ｓａ裏面と接続する。また第１領域Ｆａに形成されるスリット面Ｈ１が、裏向きとなるよう傾斜し、断面先細となる縁でシール部材１の第１領域Ｆａ表面と接続する。 When attaching the sealing member 1, as shown in FIG. 6, the second area Sa with a prospect (imaginary line in FIG. 3) is set on the side closer to the inner panel 102b, and the first area Fa without a prospect is set on the side closer to the inner panel 102b. It is set on the side far from 102b. Further, the slit surface H2 formed in the second region Sa is inclined so as to face upward, and is connected to the back surface of the second region Sa of the sealing member 1 at an edge with a tapered cross section. Further, the slit surface H1 formed in the first region Fa is inclined to face down and is connected to the surface of the first region Fa of the sealing member 1 at an edge with a tapered cross section.

第１実施形態によれば、シール部材１を取り付ける際、図６に示す取付前状態から、図９に示す取付後状態へ円滑に作業することができる。もしスリット面Ｈ１，Ｈ２の傾斜の相対的位置関係が第１実施形態と逆向きにされると、シール部材をフード下面に取り付ける際に、スリット４０で第１領域Ｆａが第２領域Ｓａと干渉し、シール部材取付作業が煩雑になり、好ましくない。 According to the first embodiment, when installing the seal member 1, it is possible to smoothly move from the pre-installation state shown in FIG. 6 to the post-installation state shown in FIG. 9. If the relative positional relationship of the inclinations of the slit surfaces H1 and H2 is reversed to that in the first embodiment, the first region Fa will interfere with the second region Sa at the slit 40 when attaching the seal member to the lower surface of the hood. However, the work for attaching the seal member becomes complicated, which is undesirable.

図９を参照して、シール部材１の長手方向に関するスリット面Ｈ１，Ｈ２の長手方向寸法は、スリット幅Ｌ１よりも大きい。またフード１０２が開位置にされる場合、シール部材１は長手方向全長においてインナーパネル１０２ｂを覆い、シール部材１の表側から裏側へ帯厚方向にみて、インナーパネル１０２ｂはスリット４０越しに見えない。 Referring to FIG. 9, the longitudinal dimensions of the slit surfaces H1 and H2 in the longitudinal direction of the seal member 1 are larger than the slit width L1. Further, when the hood 102 is in the open position, the seal member 1 covers the inner panel 102b over the entire length in the longitudinal direction, and the inner panel 102b is not visible through the slit 40 when viewed in the band thickness direction from the front side to the back side of the seal member 1.

第１実施形態によれば、見込みを設けない第１領域Ｆａと見込みを設ける第２領域Ｓａとを具備するシール部材１にあって、これら領域Ｆａ，Ｓａの境界に形成されるスリット面Ｈ１，Ｈ２が傾斜することから、図９に示すようにシール部材１をフード下面（インナーパネル１０２ｂ）に取り付けられると、帯厚方向にみてフード下面はシール部材１にカバーされ、スリット４０越しにフード下面が見えてしまうことが防止される。したがって第１実施形態によれば、シール部材１をフード１０２に見栄え良く取り付けることができる。 According to the first embodiment, the sealing member 1 includes a first area Fa in which a prospect is not provided and a second area Sa in which a prospect is provided, and the slit surface H1 formed at the boundary between these areas Fa and Sa, Since H2 is inclined, when the seal member 1 is attached to the lower surface of the hood (inner panel 102b) as shown in FIG. is prevented from being visible. Therefore, according to the first embodiment, the seal member 1 can be attached to the hood 102 with good appearance.

また第１実施形態によれば、図９を参照して、シール部材１の長手方向位置に関し、スリット４０とシール部材表面の接続位置と、スリット４０とシール部材裏面の接続位置が異なることから、スリット幅Ｌ１が０ｍｍよりも大きくても、つまりスリット４０が完全に閉じていなくても、図８に示すように帯厚方向にみて（シール部材１の表側から裏側にみて）スリット４０越しにフード下面が見えてしまうことが防止される。 Further, according to the first embodiment, with reference to FIG. 9, regarding the longitudinal position of the seal member 1, since the connection position between the slit 40 and the seal member surface is different from the connection position between the slit 40 and the seal member back surface, Even if the slit width L1 is larger than 0 mm, that is, even if the slit 40 is not completely closed, the hood can be seen through the slit 40 when viewed in the band thickness direction (as seen from the front side to the back side of the sealing member 1), as shown in FIG. This prevents the bottom surface from being visible.

次に、シール部材１の製造工程につき補足説明する。 Next, a supplementary explanation will be given regarding the manufacturing process of the seal member 1.

図１を参照して、シール部材１は、押出部１０と型部２０を接続してなる。第１実施形態は、スリット３０，４０を含まないスリット３０，４０間の大部分で、押出部１０とされる。また第１実施形態は、スリット３０，４０を含み、スリット３０からシール部材１の長手方向一端までの区間と、スリット４０からシール部材１の長手方向他端までの区間（つまりシール部材１の両端部）で、型部２０とされる。また、図３～図９中、押出部１０は取付基部１１と接続部１２とシール基部１３とシールリップ１４を含む。型部２０は取付基部２１，２６と接続部２２，２７とシール基部２３、２８とシールリップ２４，２９を含む。 Referring to FIG. 1, a sealing member 1 is formed by connecting an extrusion section 10 and a mold section 20. In the first embodiment, most of the area between the slits 30 and 40, which does not include the slits 30 and 40, is the extrusion part 10. Further, the first embodiment includes the slits 30 and 40, and includes a section from the slit 30 to one end in the longitudinal direction of the seal member 1, and a section from the slit 40 to the other end in the longitudinal direction of the seal member 1 (that is, both ends of the seal member 1). part) is used as the mold part 20. Further, in FIGS. 3 to 9, the extrusion portion 10 includes a mounting base 11, a connecting portion 12, a seal base 13, and a seal lip 14. The mold part 20 includes mounting bases 21, 26, connecting parts 22, 27, seal bases 23, 28, and seal lips 24, 29.

押出部１０は、押出成形機と口金を使用して作成される。これは、長手方向に関して断面形状の変化がほとんどないことから、長尺な一定断面のシール部品を製造する際に有利であり、フロントグリル１０４の略真っ直ぐな縁に沿うシール部分に採用される。型部２０は、金型と型材注入機を使用して作成される。これは、長手方向に関して断面形状が変化することから、特定の三次元形状のシール部品を製造する際に有利であり、ヘッドライト１０６のような特異な形状に沿うシール部分に採用される。 The extrusion section 10 is created using an extrusion molding machine and a die. This is advantageous when manufacturing a long seal component with a constant cross section because there is almost no change in the cross-sectional shape in the longitudinal direction, and is adopted for the seal portion along the substantially straight edge of the front grille 104. The mold section 20 is created using a mold and a mold material injector. Since the cross-sectional shape changes in the longitudinal direction, this is advantageous when manufacturing a seal component with a specific three-dimensional shape, and is employed in a seal portion that follows a unique shape, such as the headlight 106.

押出部１０と型部２０の接合箇所Ｃは三角形のマークで表される。三角形の白抜き部側は、押出部１０側である事を示し、三角形の黒塗り部側は、型部２０側である事を示す。
接合箇所Ｃはシール部材１の長手方向に直角な平面同士を接着してなる。第１実施形態では、スリット３０，４０の長手方向位置と、接合箇所Ｃの長手方向位置が異なる。図６を参照して、スリット４０を構成する１対のスリット面Ｈ１，Ｈ２は共に型部２０として構成される。 The joining point C between the extrusion part 10 and the mold part 20 is represented by a triangular mark. The white part side of the triangle indicates the extrusion part 10 side, and the black part side of the triangle indicates the mold part 20 side.
The joint portion C is formed by bonding together planes perpendicular to the longitudinal direction of the seal member 1. In the first embodiment, the longitudinal position of the slits 30 and 40 is different from the longitudinal position of the joint C. Referring to FIG. 6, a pair of slit surfaces H1 and H2 constituting slit 40 are both configured as mold section 20. As shown in FIG.

第１実施形態によれば、金型によって、段違い形状のスリット４０を製造することができ、スリット４０の傾斜角度を精度良く製造することができる。またシール部材１は長手方向途中に押出部１０を含むことから、長尺なシール部材１を効率良く製造することができる。 According to the first embodiment, the slit 40 having a stepped shape can be manufactured using a mold, and the inclination angle of the slit 40 can be manufactured with high precision. Furthermore, since the seal member 1 includes the extruded portion 10 midway in the longitudinal direction, a long seal member 1 can be manufactured efficiently.

ここで附言すると、図５を参照して、スリット面Ｈ１，Ｈ２の接続部に面取を設ける。面取の例として本実施形態では、円弧状の面取Ｒが設けられる。仮にスリット面Ｈ１，Ｈ２の接続部に面取りを設けない場合、金型を用いて成形しようとすると、金型の該当部分（中芯形状）が鋭利な先細形状となり、中芯形状が破損しやすく、長期間に亘ってシール部材１を型成形するには好ましくない。 To add here, referring to FIG. 5, a chamfer is provided at the connecting portion of the slit surfaces H1 and H2. As an example of the chamfer, in this embodiment, an arc-shaped chamfer R is provided. If a chamfer is not provided at the connecting part of the slit surfaces H1 and H2, when molding is attempted using a mold, the corresponding part of the mold (core shape) becomes a sharp tapered shape, and the core shape is easily damaged. This is not preferable for molding the seal member 1 over a long period of time.

そのため、取付後のスリット幅Ｌ１＝０．６ｍｍ程度とし、スリット面Ｈ１とＨ２の接続部を面取形状（面取の半径Ｒ＝０．３ｍｍ程度）にすることにより、使用する金型の中芯形状の先端が破損し難く、長期間シール部材１を型成形するのに好ましい。 Therefore, by setting the slit width L1 = approximately 0.6 mm after installation and making the connecting part of the slit surfaces H1 and H2 a chamfered shape (chamfer radius R = approximately 0.3 mm), it is possible to The tip of the core shape is difficult to damage, and is preferable for molding the sealing member 1 for a long period of time.

次に本発明の第２実施形態につき説明する。 Next, a second embodiment of the present invention will be described.

図１０および図１１は、本発明の第２実施形態を示す背面図であり、帯幅方向一側から他側をみた状態を表し、第１実施形態の図６および図９に対応する。図１０は取付前の状態、図１１は取付後の状態である。図１２はフード下面に取り付けられた第２実施形態のシール部材２を示す底面図であり、シール部材２の表面を示し、取付基部１１，２１の表面に対して略垂直な方向で見た状態を表す。第２実施形態につき、前述した実施形態と共通する構成については同一の符号を付して説明を省略し、異なる構成について以下に説明する。第２実施形態では、接合箇所Ｃの長手方向位置とスリット４０の長手方向位置が一致する。換言すると、第１領域Ｆａ全てが型部２０であり、第２領域Ｓａ全てが押出部１０である。 10 and 11 are rear views showing the second embodiment of the present invention, showing the state seen from one side in the band width direction to the other side, and correspond to FIGS. 6 and 9 of the first embodiment. FIG. 10 shows the state before installation, and FIG. 11 shows the state after installation. FIG. 12 is a bottom view showing the seal member 2 of the second embodiment attached to the lower surface of the hood, showing the surface of the seal member 2, viewed in a direction substantially perpendicular to the surfaces of the mounting bases 11 and 21. represents. Regarding the second embodiment, the same reference numerals are given to the same configurations as those of the above-described embodiments, and the explanation thereof will be omitted, and the different configurations will be explained below. In the second embodiment, the longitudinal position of the joint portion C and the longitudinal position of the slit 40 match. In other words, the entire first area Fa is the mold part 20, and the entire second area Sa is the extrusion part 10.

第２実施形態のスリット４０は、互いに対向する１対のスリット面Ｈ３，Ｈ４で構成され、各スリット面Ｈ３，Ｈ４は傾斜面である。第１実施形態のスリット４０とは異なり、第２実施形態のスリット４０のスリット面Ｈ４は、押出部１０側である。このため例えば、押出部１０の素形材を作成後に、素形材の端傾斜面になるように裁断して、スリット面Ｈ４が作成される。 The slit 40 of the second embodiment is composed of a pair of slit surfaces H3 and H4 facing each other, and each slit surface H3 and H4 is an inclined surface. Unlike the slit 40 of the first embodiment, the slit surface H4 of the slit 40 of the second embodiment is on the extrusion section 10 side. For this reason, for example, after creating the raw material of the extrusion part 10, the raw material is cut so as to have an inclined end surface, thereby creating the slit surface H4.

図１１を参照して、取付後のスリット４０の幅Ｌ２は、取付前の互い違い寸法Ｄ（図１０）よりも狭くなり、具体的には０．６ｍｍ以下である。またＬ２＝０ｍｍとなり完全に閉じてもよい。第２実施形態によれば、前述した第１実施形態と同様、フード１０２の開位置でシール基部１３，２３が垂れ下がることが防止され、フード前縁１０２ｄはシール部材２によって見栄え良くカバーされるとともに、シール部材２の表側から裏側に帯厚方向にみてスリット４０越しにフード下面（インナーパネル１０２ｂ）が見えてしまう事が防止される。 Referring to FIG. 11, the width L2 of the slit 40 after attachment is narrower than the staggered dimension D (FIG. 10) before attachment, and specifically is 0.6 mm or less. Alternatively, it may be completely closed with L2=0 mm. According to the second embodiment, similar to the first embodiment described above, the seal bases 13 and 23 are prevented from hanging down when the hood 102 is in the open position, and the front edge 102d of the hood is covered with a good appearance by the seal member 2. This prevents the lower surface of the hood (inner panel 102b) from being visible through the slit 40 when viewed in the band thickness direction from the front side to the back side of the sealing member 2.

次に本発明の第３実施形態につき説明する。 Next, a third embodiment of the present invention will be described.

図１３および図１４は、本発明の第３実施形態を示す背面図であり、帯幅方向一側から他側をみた状態を表し、第１実施形態の図６および図９に対応する。第３実施形態につき、前述した実施形態と共通する構成については同一の符号を付して説明を省略し、異なる構成について以下に説明する。第３実施形態のシール部材３は、前述したシール部材１，２と共通する基本構成を有するが、スリット４０を構成するスリット面が傾斜面ではなく、シール部材３の帯厚方向と平行である。 13 and 14 are rear views showing the third embodiment of the present invention, showing the state seen from one side in the band width direction to the other side, and correspond to FIGS. 6 and 9 of the first embodiment. Regarding the third embodiment, the same reference numerals are given to the same configurations as those of the above-described embodiments, and the explanation thereof is omitted, and the different configurations will be explained below. The seal member 3 of the third embodiment has the same basic configuration as the seal members 1 and 2 described above, but the slit surface forming the slit 40 is not an inclined surface but parallel to the band thickness direction of the seal member 3. .

スリット４０で隣り合う取付基部１１と取付基部２１は、図１３に示す取付前の状態で互い違い寸法Ｄだけ互い違いに開いているが、図１４に示す取付後の状態でスリット４０が狭くなって閉じる。図１４中、スリット幅Ｌ３＝０ｍｍであり、スリット４０は完全に閉じる。 The mounting bases 11 and 21 adjacent to each other at the slits 40 are open alternately by an alternating dimension D in the pre-installation state shown in FIG. 13, but the slits 40 narrow and close in the post-installation state shown in FIG. . In FIG. 14, the slit width L3 is 0 mm, and the slit 40 is completely closed.

第３実施形態によれば、前述した実施形態と同様、フードの開位置でシール基部１３，２３が垂れ下がることが防止され、フード前縁１０２ｄはシール部材３によって見栄え良くカバーされるとともに、シール部材３の表側から裏側に帯厚方向にみてスリット４０越しにフード下面（インナーパネル１０２ｂ）が見えてしまう事が防止される。なお第３実施形態のスリット４０は、前述した実施形態と同様、シール部材３の長手方向と直交して延びる。あるいは図示はしなかったが、第１～第３実施形態の変形例としてスリット４０は、シール部材３の長手方向に対して斜めに延びてもよい。 According to the third embodiment, similar to the embodiments described above, the seal bases 13 and 23 are prevented from hanging down in the open position of the hood, the front edge 102d of the hood is covered with a good appearance by the seal member 3, and the seal member The lower surface of the hood (inner panel 102b) is prevented from being seen through the slit 40 when viewed in the band thickness direction from the front side to the back side of 3. Note that the slit 40 of the third embodiment extends perpendicularly to the longitudinal direction of the seal member 3, similar to the embodiment described above. Alternatively, although not shown, as a modification of the first to third embodiments, the slit 40 may extend obliquely to the longitudinal direction of the seal member 3.

次に本発明の第４実施形態につき説明する。 Next, a fourth embodiment of the present invention will be described.

図１５および図１６は、本発明の第４実施形態を示す背面図であり、帯幅方向一側から他側をみた状態を表し、第１実施形態の図６および図９に対応する。第４実施形態につき、前述した実施形態と共通する構成については同一の符号を付して説明を省略し、異なる構成について以下に説明する。第４実施形態のシール部材４は、前述したシール部材１と共通する基本構成を有するが、スリット４０を構成するスリット面Ｈ５，Ｈ６が傾斜面ではなく段差面である。具体的には、スリット面Ｈ５，Ｈ６が階段状である。シール部材４の長手方向に関し、スリット面Ｈ５，Ｈ６の長手方向寸法は、後述するスリット幅Ｌ４よりも大きい。 15 and 16 are rear views showing the fourth embodiment of the present invention, showing the state seen from one side in the band width direction to the other side, and correspond to FIGS. 6 and 9 of the first embodiment. Regarding the fourth embodiment, the same reference numerals are given to the same configurations as those of the above-described embodiments, and the explanation thereof will be omitted, and the different configurations will be explained below. The seal member 4 of the fourth embodiment has the same basic configuration as the seal member 1 described above, but the slit surfaces H5 and H6 forming the slit 40 are not inclined surfaces but stepped surfaces. Specifically, the slit surfaces H5 and H6 are stepped. Regarding the longitudinal direction of the seal member 4, the longitudinal dimensions of the slit surfaces H5 and H6 are larger than the slit width L4, which will be described later.

また、前述したシール部材２と同様に、第４実施形態のスリット４０のスリット面Ｈ６は、押出部１０を作成後にスリット面Ｈ６が階段状になるように裁断すれば良いとも考えられるが、押出部（接合箇所Ｃよりも紙面左側）があまり硬くない為、前述した傾斜面Ｈ４のような平坦面に裁断する事は出来ても、階段状に裁断する事は困難である。そのため、第４実施形態のスリット４０は、第１実施形態のスリット４０と同様に、型成形で作成するのが好ましい。 Further, similar to the sealing member 2 described above, the slit surface H6 of the slit 40 in the fourth embodiment may be cut so that the slit surface H6 becomes step-like after the extrusion part 10 is created. Since the part (on the left side of the paper plane than the joining point C) is not very hard, it is difficult to cut into a step shape even though it is possible to cut into a flat surface like the above-mentioned inclined surface H4. Therefore, it is preferable that the slit 40 of the fourth embodiment be created by molding, similarly to the slit 40 of the first embodiment.

図１６を参照してシール部材４の取付後のスリット４０のスリット幅Ｌ４は、図１５に示す取付前の互い違い寸法Ｄよりも狭く、例えば０．６ｍｍあるいは０．６ｍｍ以下の所定値である。なお変形例として、Ｌ４＝０、つまりスリット４０は完全に閉じてもよい。 Referring to FIG. 16, the slit width L4 of the slit 40 after the seal member 4 is attached is narrower than the staggered dimension D before attachment shown in FIG. 15, for example, 0.6 mm or a predetermined value of 0.6 mm or less. Note that as a modification, L4=0, that is, the slit 40 may be completely closed.

第４実施形態によれば、前述した実施形態と同様、フードの開位置でシール基部１３，２３が垂れ下がることが防止され、フード前縁１０２ｄはシール部材４によって見栄え良くカバーされるとともに、シール部材４の表側から裏側に帯厚方向にみてスリット４０越しにフード下面（インナーパネル１０２ｂ）が見えてしまう事が防止される。なお第４実施形態では、スリット面Ｈ５，Ｈ６の階段形状が、帯厚寸法を２等分する２段とされる。あるいは図示しない変形例として、スリット面Ｈ５，Ｈ６の階段形状は、大小異なる２段とされてもよい。あるいは図示しない変形例として、スリット面Ｈ５，Ｈ６の階段形状は、３段以上の多段とされてもよい。 According to the fourth embodiment, similar to the embodiments described above, the seal bases 13 and 23 are prevented from hanging down in the open position of the hood, the front edge 102d of the hood is covered with a good appearance by the seal member 4, and the seal member The lower surface of the hood (inner panel 102b) is prevented from being seen through the slit 40 when viewed in the band thickness direction from the front side to the back side of the hood. In the fourth embodiment, the step shape of the slit surfaces H5 and H6 is two steps that equally divide the band thickness dimension into two. Alternatively, as a modification (not shown), the slit surfaces H5 and H6 may have two steps of different sizes. Alternatively, as a modification (not shown), the slit surfaces H5, H6 may have a multi-step shape of three or more steps.

本発明のシール部材１～４によれば、例えばフード前縁１０２ｄやヘッドライト１０６が独特なデザインを有するためにフード前縁１０２ｄとヘッドライト１０６の隙間を封止するシール部材１～４の断面形状が長手方向の部位によって断面形状が大きく複雑に変化する場合であっても、第１領域Ｆａおよび第２領域Ｓａを開口縁１０１ａの形状に合致するよう適切に配置することができ、開口縁１０１ａを確実にシールすることができる。またフード１０２を起立させて開位置にしても、シール部材１～４はフード１０２に見栄え良く取付固定された状態を保持する。 According to the seal members 1 to 4 of the present invention, for example, since the hood front edge 102d and the headlight 106 have a unique design, the cross section of the seal members 1 to 4 sealing the gap between the hood front edge 102d and the headlight 106. Even if the cross-sectional shape changes greatly and complicatedly depending on the longitudinal region, the first region Fa and the second region Sa can be appropriately arranged to match the shape of the opening edge 101a, and the opening edge 101a can be reliably sealed. Further, even when the hood 102 is erected to the open position, the seal members 1 to 4 remain attached and fixed to the hood 102 with a good appearance.

また本発明によれば、従来のようなエンジンフードの前縁が車体の左縁から右縁まで直線状に延びる形状でも適用可能であること勿論、フロントグリルの前縁と、ヘッドライトの前縁が相互に不揃いであっても、適用可能である。 Further, according to the present invention, it is possible to apply the engine hood even if the leading edge of the engine hood extends in a straight line from the left edge to the right edge of the vehicle body as in the conventional case. It is applicable even if they are not aligned with each other.
