Description

本発明は、車両の給油口付近を被覆して、給油口付近への泥や水等の侵入を防止する被覆部材に関する。   The present invention relates to a covering member that covers the vicinity of a fuel filler opening of a vehicle and prevents intrusion of mud, water, and the like near the filler opening.

車両に燃料を供給するための給油口は、燃料タンクから延びるインレットフィラーパイプの先端部から構成される。燃料タンクは車体の下方などに配設される。車体の一部を構成する外側パネル(所謂サイドメンバアウタ)には、インレットフィラーパイプの先端部を車体の外側に導くための開口(外側開口)が形成されている。燃料タンクの配置位置や車体の形状によっては、車体の一部を構成する内側パネル(所謂ホイルハウスアウタ)にも、インレットフィラーパイプの先端部を車体の外側に導くための開口(内側開口)が形成されている場合もある。   A fuel filler port for supplying fuel to the vehicle is constituted by a tip portion of an inlet filler pipe extending from the fuel tank. The fuel tank is disposed below the vehicle body. An outer panel (so-called side member outer) constituting a part of the vehicle body is formed with an opening (outer opening) for guiding the tip of the inlet filler pipe to the outside of the vehicle body. Depending on the position of the fuel tank and the shape of the vehicle body, the inner panel (so-called wheelhouse outer) that forms part of the vehicle body also has an opening (inner opening) for guiding the tip of the inlet filler pipe to the outside of the vehicle body. It may be formed.

ところで、外側パネルの外側面は車体の外側外部に露出する。内側パネルの内側面は車体の内側外部に露出する。このため、雨水などが外側開口や内側開口を介して車体の内部に侵入するおそれがある。車体の内部への雨水等の侵入を抑制するために、筒状の被覆部材によって外側開口(または外側開口と内側開口)を覆う技術が提案されている(例えば、特許文献1参照)。   By the way, the outer surface of the outer panel is exposed outside the vehicle body. The inner surface of the inner panel is exposed outside the vehicle body. For this reason, rainwater or the like may enter the inside of the vehicle body through the outer opening or the inner opening. In order to suppress intrusion of rainwater or the like into the interior of the vehicle body, a technique for covering the outer opening (or the outer opening and the inner opening) with a cylindrical covering member has been proposed (for example, see Patent Document 1).

特許文献1の被覆部材を模式的に表す断面図を図9に示す。特許文献1の被覆部材600は、外側開口140を覆う外側被覆部101を持つ。特許文献1の被覆部材における外側被覆部101は、係合爪161を一体に持つ補強部160と、補強部160を覆うラバー被覆部170とを持つ。係合爪161は外周方向に突出する爪状をなす。係合爪161の突出端部の外周面は外側開口140の内周面よりも大径である。したがって、外側被覆部101を外側開口140に取り付けると、係合爪161の突出端部が外側開口140の内周面と係合する。   A cross-sectional view schematically showing the covering member of Patent Document 1 is shown in FIG. The covering member 600 of Patent Document 1 has an outer covering portion 101 that covers the outer opening 140. The outer covering portion 101 in the covering member of Patent Document 1 has a reinforcing portion 160 that integrally has an engaging claw 161 and a rubber covering portion 170 that covers the reinforcing portion 160. The engaging claw 161 has a claw shape protruding in the outer peripheral direction. The outer peripheral surface of the protruding end of the engaging claw 161 has a larger diameter than the inner peripheral surface of the outer opening 140. Therefore, when the outer covering portion 101 is attached to the outer opening 140, the protruding end portion of the engaging claw 161 is engaged with the inner peripheral surface of the outer opening 140.

特許文献1の被覆部材によると、外側被覆部101を外側開口140に圧入する際に、係合爪161が撓んで外側開口140の内周面を乗り越え、外側開口140の周縁部(以下、外側周縁部141と呼ぶ)の内側面に係合する。このため、特許文献1の被覆部材によると、外側被覆部101を車体の外側周縁部141に容易に取り付け得る。   According to the covering member of Patent Document 1, when the outer covering portion 101 is press-fitted into the outer opening 140, the engaging claw 161 is bent to overcome the inner peripheral surface of the outer opening 140, and the peripheral portion of the outer opening 140 (hereinafter referred to as the outer portion). Engage with the inner surface of the peripheral portion 141. For this reason, according to the covering member of Patent Document 1, the outer covering portion 101 can be easily attached to the outer peripheral edge portion 141 of the vehicle body.

しかし、図9に示すように、係合爪161の取り付け面161aと補強部160の外周面160bとがなす角βは鈍角である。このため、外側周縁部141の径方向長さが短い場合(外側開口140の開口径が大きい場合)には、外側周縁部141は係合爪161の取り付け面161aにただ載置されるだけになる可能性が高い。この場合には、外側被覆部101によって外側周縁部141を充分にシールできない。外側パネル400は、一般に金属からなる大型の部材であるため、比較的成形精度に劣る。このため、外側周縁部141の径方向長さにばらつきが生じる可能性が高く、外側被覆部101によって外側周縁部141を充分にシールできない不具合が生じる可能性が高い。したがって特許文献1の被覆部材によると、雨水等が車体の内部に侵入する問題を依然解決できない問題があった。   However, as shown in FIG. 9, the angle β formed by the mounting surface 161 a of the engaging claw 161 and the outer peripheral surface 160 b of the reinforcing portion 160 is an obtuse angle. For this reason, when the radial length of the outer peripheral edge portion 141 is short (when the opening diameter of the outer opening 140 is large), the outer peripheral edge portion 141 is merely placed on the mounting surface 161a of the engaging claw 161. Is likely to be. In this case, the outer peripheral edge 141 cannot be sufficiently sealed by the outer covering portion 101. Since the outer panel 400 is a large member generally made of metal, it is relatively inferior in molding accuracy. For this reason, there is a high possibility that the radial length of the outer peripheral edge portion 141 will vary, and there is a high possibility that the outer peripheral edge portion 141 cannot be sufficiently sealed by the outer covering portion 101. Therefore, according to the covering member of Patent Document 1, there is still a problem that the problem of rainwater and the like entering the inside of the vehicle body still cannot be solved.

さらに、特許文献1の被覆部材における係合爪161は、ゴム製のラバー被覆部170で被覆されている。このため、係合爪161を外側開口140に圧入する際の抵抗が大きくなる。よって、特許文献1の被覆部材は、車体への取り付け作業性に劣る問題もあった。
特開2005−125949号公報
Furthermore, the engaging claw 161 in the covering member of Patent Document 1 is covered with a rubber rubber covering portion 170. For this reason, the resistance at the time of press-fitting the engaging claw 161 into the outer opening 140 is increased. Therefore, the covering member of Patent Document 1 also has a problem that it is inferior in mounting workability to the vehicle body.

本発明の被覆部材の取り付け方法は、下記の(6)を備えることが好ましい。
(6)上記押圧連結部は弾性体からなる。
The method for attaching the covering member of the present invention preferably comprises the following (6).
(6) The pressing connection portion is made of an elastic body.

本発明の第1の被覆部材および第2の被覆部材は、弾性材料からなるシール部材と、硬質材料からなりシール部材に一体化されている規制部材とを持つ。規制部材のフランジ部は、外側開口の周縁部(外側周縁部)の外側面を覆う。規制部材の爪部は、外側周縁部の内側面の少なくとも一部に当接する。シール部材の規制シール部は、脚部およびフランジ部の内周面(または脚部の内周面)を覆う。シール部材の圧縮シール部は、外側周縁部の外側面とフランジ部の内側面との間に介在する。このため、第1の被覆部材および第2の被覆部材は、爪部とフランジ部とで、外側周縁部と圧縮シール部とを挟み込む。また、フランジ部の内側面と爪部の外側面との最短距離L1は、圧縮シール部の肉厚L2と外側開口の周縁部(外側周縁部)の肉厚L3との和よりも小さい。このため圧縮シール部は、フランジ部と外側周縁部との間に圧縮状態で介在し、両者に圧接する。よって、本発明の第1の被覆部材および第2の被覆部材によると、規制部材とシール部材とによって外側周縁部を充分にシールでき、雨水等の車体内部への侵入を抑制できる。また、規制部材とシール部材とは外側周縁部を厚さ方向にシールするため、外側周縁部の位置が外側−内側方向にばらついた場合や、外側周縁部の肉厚にバラツキがある場合にも、充分なシール性能を発揮する。   The first covering member and the second covering member of the present invention have a sealing member made of an elastic material and a regulating member made of a hard material and integrated with the sealing member. The flange part of a control member covers the outer surface of the peripheral part (outer peripheral part) of an outer side opening. The claw portion of the restricting member contacts at least a part of the inner side surface of the outer peripheral edge portion. The restriction seal portion of the seal member covers the inner peripheral surface of the leg portion and the flange portion (or the inner peripheral surface of the leg portion). The compression seal portion of the seal member is interposed between the outer surface of the outer peripheral edge portion and the inner surface of the flange portion. For this reason, the first covering member and the second covering member sandwich the outer peripheral edge portion and the compression seal portion between the claw portion and the flange portion. Further, the shortest distance L1 between the inner surface of the flange portion and the outer surface of the claw portion is smaller than the sum of the thickness L2 of the compression seal portion and the thickness L3 of the peripheral portion (outer peripheral portion) of the outer opening. For this reason, the compression seal portion is interposed between the flange portion and the outer peripheral edge portion in a compressed state, and is pressed against both. Therefore, according to the first covering member and the second covering member of the present invention, the outer peripheral edge can be sufficiently sealed by the regulating member and the sealing member, and intrusion of rainwater or the like into the vehicle body can be suppressed. In addition, since the regulating member and the seal member seal the outer peripheral edge in the thickness direction, even when the position of the outer peripheral edge varies in the outer-inner direction or when the thickness of the outer peripheral edge varies. Exhibits sufficient sealing performance.

さらに、爪部の外側面と脚部の外周面とがなす角αは、0°よりも大きく90°以下である。このため爪部は、外側周縁部の径方向長さが短い場合(外側開口の開口径が大きい場合)にも、外側周縁部の内側面に当接する。したがって、外側周縁部の径方向長さが短い場合にも、爪部とフランジ部とは外側周縁部を挟み込むことができ、かつ、圧縮シール部は充分に圧縮してフランジ部を外側周縁部とに圧接する。よって、本発明の第1の被覆部材および第2の被覆部材によると、雨水等の車体内部への侵入を抑制できる。   Furthermore, the angle α formed by the outer surface of the claw and the outer peripheral surface of the leg is greater than 0 ° and 90 ° or less. For this reason, a nail | claw part contact | abuts to the inner surface of an outer periphery part also when the radial direction length of an outer periphery part is short (when the opening diameter of an outer side opening is large). Therefore, even when the radial length of the outer peripheral edge portion is short, the claw portion and the flange portion can sandwich the outer peripheral edge portion, and the compression seal portion is sufficiently compressed so that the flange portion becomes the outer peripheral edge portion. Press contact. Therefore, according to the first covering member and the second covering member of the present invention, it is possible to suppress intrusion of rainwater or the like into the vehicle body.

さらに、本発明の第1の被覆部材および第2の被覆部材によると、爪部はシール部材で覆われていないため、爪部を外側開口に圧入する際の抵抗は小さくて済む。よって本発明の第1の被覆部材および第2の被覆部材は、車体への取り付け作業性に優れる。   Furthermore, according to the first covering member and the second covering member of the present invention, since the claw portion is not covered with the seal member, the resistance when the claw portion is press-fitted into the outer opening may be small. Therefore, the 1st covering member and the 2nd covering member of the present invention are excellent in workability to attachment to a vehicle body.

本発明の第2の被覆部材において、規制部材は樹脂材料からなり、シール部材はこの樹脂材料と融着可能な熱可塑性エラストマ材料からなる。そして、規制部材とシール部材とは一体成形されてなる。このため、本発明の第2の被覆部材における規制部材とシール部材とは融着して強固に一体化する。さらに、規制部材には脚部の内周側と外周側とを連通する規制連通口が設けられており、シール部材の規制シール部は規制連通口を通じて圧縮シール部に連続する。このため、規制部材とシール部材とは脱離し難い。よって、本発明の第2の被覆部材は、外側周縁部に対するシール性により一層優れる。すなわち本発明の第2の被覆部材は、雨水等の車体内部への侵入をさらに抑制できる。   In the second covering member of the present invention, the regulating member is made of a resin material, and the seal member is made of a thermoplastic elastomer material that can be fused to the resin material.

For this reason, the claw part and the flange part press the compression seal part over a wide range. The compression seal portion is securely pressed against the outer peripheral edge portion and the flange portion. Therefore, the 1st covering member and the 2nd covering member of the present invention provided with the above (2) are excellent in the sealing performance to an outer periphery part.

上記(3)を備える本発明の第1の被覆部材および第2の被覆部材は、シール部材とインレットフィラーパイプとの隙間を管シール部によってシールできるため、雨水等の車体内部への侵入をさらに抑制できる。   The first covering member and the second covering member according to the present invention having the above (3) can seal the gap between the seal member and the inlet filler pipe with the tube seal portion.

As shown in FIG. 1 and FIG. 2, the portion located at the lowermost portion of the coupling seal portion 33 when attached to the vehicle body is recessed toward the inner peripheral side.

図1に示すように、実施例1の被覆部材6は、車体の外側パネル4に形成されている外側開口40の周縁部(外側周縁部41)と、車体の内側パネル5に形成されている内側開口50の周縁部(内側周縁部51)とに取り付けられる。詳しくは、第1の規制部材10と外側シール部31とが外側周縁部41を挟み込み、第2の規制部材20と内側シール部32とが内側周縁部51を挟み込む。   As shown in FIG. 1, the covering member 6 according to the first embodiment is formed on the peripheral portion (outer peripheral portion 41) of the outer opening 40 formed on the outer panel 4 of the vehicle body and on the inner panel 5 of the vehicle body. It is attached to the peripheral edge (inner peripheral edge 51) of the inner opening 50. Specifically, the first restricting member 10 and the outer seal portion 31 sandwich the outer peripheral edge portion 41, and the second restricting member 20 and the inner seal portion 32 sandwich the inner peripheral edge portion 51.

実施例1の被覆部材6においては、第1の規制部材10の第1の脚部12が外側開口40の内周面に近接する。第1のフランジ部11は第1の圧縮シール部313を介して外側周縁部41の外側面410を覆う。第1の爪部13の第1当接面13aは、外側周縁部41の内側面411に当接する。このため、第1のフランジ部11と第1の爪部13とは第1の圧縮シール部313を介して外側周縁部41を挟み込む。   In the covering member 6 of the first embodiment, the first leg 12 of the first restricting member 10 is close to the inner peripheral surface of the outer opening 40. The first flange portion 11 covers the outer surface 410 of the outer peripheral edge portion 41 via the first compression seal portion 313. The first contact surface 13 a of the first claw portion 13 contacts the inner side surface 411 of the outer peripheral edge portion 41. For this reason, the first flange portion 11 and the first claw portion 13 sandwich the outer peripheral edge portion 41 via the first compression seal portion 313.

図3に示すように、第1のフランジ部11の内側面110と第1の爪部13の外側面(第1当接面13a)との最短距離L1は、第1の圧縮シール部313の肉厚L2と外側周縁部41の肉厚L3との和よりも小さく設定されている。このため、第1のフランジ部11と第1の爪部13とで外側周縁部41を挟み込むと、第1の圧縮シール部313は、第1のフランジ部11の内側面110と外側周縁部41の外側面410とに圧接して、外側周縁部41の外側面410に垂直な方向に圧縮する。第1の圧縮シール部313の圧縮長さは、L2およびL3の和と、L1と、の差(L0)である。このため第1の圧縮シール部313は、外側周縁部41の位置が外側−内側方向にばらついた場合や、外側周縁部41の肉厚にばらつきがある場合にも、このばらつきを吸収し、かつ、第1のフランジ部11の内側面110と外側周縁部41の外側面410とに圧接する。したがって、実施例1の被覆部材6は外側周縁部41に対するシール性に優れる。よって、実施例1の被覆部材6によると、雨水等の車体内部9への侵入を抑制できる。   As shown in FIG. 3, the shortest distance L1 between the inner side surface 110 of the first flange portion 11 and the outer side surface (first contact surface 13a) of the first claw portion 13 is equal to the first compression seal portion 313. It is set smaller than the sum of the thickness L2 and the thickness L3 of the outer peripheral edge 41. Therefore, when the outer peripheral edge portion 41 is sandwiched between the first flange portion 11 and the first claw portion 13, the first compression seal portion 313 is connected to the inner side surface 110 and the outer peripheral edge portion 41 of the first flange portion 11. The outer peripheral surface 410 is pressed against the outer peripheral surface 41 and compressed in a direction perpendicular to the outer peripheral surface 410 of the outer peripheral edge portion 41. The compression length of the first compression seal portion 313 is a difference (L0) between the sum of L2 and L3 and L1. For this reason, the first compression seal portion 313 absorbs this variation even when the position of the outer peripheral edge portion 41 varies in the outer-inner direction or when the outer peripheral edge portion 41 has a variation in thickness, and The inner surface 110 of the first flange portion 11 and the outer surface 410 of the outer peripheral edge portion 41 are pressed against each other. Therefore, the covering member 6 of Example 1 is excellent in the sealing performance with respect to the outer peripheral edge portion 41. Therefore, according to the covering member 6 of the first embodiment, intrusion of rainwater or the like into the vehicle interior 9 can be suppressed.

また、第2のフランジ部21と第2の爪部23とは、第2の圧縮シール部323を介して内側周縁部51を挟み込む。図示しないが、第2のフランジ部21の内側面と第2の爪部23の外側面(第2当接面23a)との最短距離L4は、第2の圧縮シール部323の肉厚L5と内側周縁部51の肉厚L6との和よりも小さく設定されている。このため、第2のフランジ部21と第2の爪部23とで内側周縁部51を挟み込むと、第2の圧縮シール部323は、第2のフランジ部21の内側面210と内側周縁部51の外側面510とに圧接して、内側周縁部51の外側面510に垂直な方向に圧縮する。このため第2の圧縮シール部323は、内側周縁部51の位置が外側−内側方向にばらついた場合や、内側周縁部51の肉厚にばらつきがある場合にも、このばらつきを吸収し、かつ、第2のフランジ部21の内側面210と内側周縁部51の外側面510とに圧接する。よって、実施例1の被覆部材6は内側周縁部51に対するシール性にも優れる。   Further, the second flange portion 21 and the second claw portion 23 sandwich the inner peripheral edge portion 51 via the second compression seal portion 323. Although not shown, the shortest distance L4 between the inner surface of the second flange portion 21 and the outer surface (second contact surface 23a) of the second claw portion 23 is the thickness L5 of the second compression seal portion 323. It is set smaller than the sum of the inner peripheral edge 51 and the thickness L6. Therefore, when the inner peripheral edge portion 51 is sandwiched between the second flange portion 21 and the second claw portion 23, the second compression seal portion 323 is connected to the inner side surface 210 and the inner peripheral edge portion 51 of the second flange portion 21. The outer peripheral surface 510 is pressed against the outer peripheral surface 510 and compressed in a direction perpendicular to the outer peripheral surface 510 of the inner peripheral edge 51. For this reason, the second compression seal portion 323 absorbs this variation even when the position of the inner peripheral edge 51 varies in the outer-inner direction or when the inner peripheral edge 51 has a variation in thickness, and The inner surface 210 of the second flange portion 21 and the outer surface 510 of the inner peripheral edge 51 are pressed against each other. Therefore, the covering member 6 of Example 1 is also excellent in the sealing performance with respect to the inner peripheral edge 51.

さらに、第1の圧縮シール部313は第1のリップ315を持つため、外側周縁部41の外側面410に線接触する。このため第1の圧縮シール部313は、外側周縁部41の外側面410に対するシール面圧に優れる。よって実施例1の被覆部材6は外側周縁部41に対するシール性に優れる。同様に、第2の圧縮シール部323は第2のリップ325を持つため、内側周縁部51の外側面510に対するシール面圧に優れる。よって、実施例1の被覆部材6は内側周縁部51に対するシール性にも優れる。   Further, since the first compression seal portion 313 has the first lip 315, the first compression seal portion 313 is in line contact with the outer surface 410 of the outer peripheral edge portion 41. For this reason, the first compression seal portion 313 is excellent in the seal surface pressure against the outer surface 410 of the outer peripheral edge portion 41. Therefore, the covering member 6 of Example 1 is excellent in the sealing performance with respect to the outer peripheral edge portion 41. Similarly, since the second compression seal portion 323 has the second lip 325, the seal pressure against the outer surface 510 of the inner peripheral edge portion 51 is excellent. Therefore, the covering member 6 of Example 1 is also excellent in the sealing performance with respect to the inner peripheral edge 51.

なお、雨水等は、外側周縁部41の外周側から内周側に向けて流れ込み、車体内部9に侵入する。また、内側周縁部51の内周側から外周側に向けて流れ込み、車体内部9に侵入する。実施例1の被覆部材6においては、第1のリップ315は第1の規制部材10の外周方向かつ内側に向けて突出する。また、第2のリップ325は第2の規制部材20の内周方向かつ内側に向けて突出する。このため、第1のリップ315および第2のリップ325は、雨水等の進入経路上流側に向けて突出している。よって、実施例1の被覆部材6は、第1のリップ315および第2のリップ325によって雨水等を遮断できるため、車体内部9への雨水等の侵入をより確実に抑制できる。   Note that rainwater or the like flows from the outer peripheral side of the outer peripheral edge portion 41 toward the inner peripheral side, and enters the interior 9 of the vehicle body. Further, the air flows from the inner peripheral side of the inner peripheral edge portion 51 toward the outer peripheral side, and enters the inside 9 of the vehicle body. In the covering member 6 according to the first embodiment, the first lip 315 protrudes in the outer peripheral direction and the inner side of the first restricting member 10. Further, the second lip 325 protrudes inwardly and inward of the second restricting member 20. For this reason, the 1st lip 315 and the 2nd lip 325 protrude toward the approach path | route upstream, such as rain water. Therefore, since the covering member 6 according to the first embodiment can block rainwater and the like by the first lip 315 and the second lip 325, the intrusion of rainwater and the like into the vehicle interior 9 can be more reliably suppressed.

さらに、第1の爪部13の外側面(第1当接面13a)と、第1の脚部12の外周面123とがなす角αは90°であるため、第1の爪部13は外側周縁部41の内側面411に面接触する。このため、第1の爪部13と第1のフランジ部11とは、第1の圧縮シール部313を広範囲にわたって押圧する。よって第1の圧縮シール部313は、外側周縁部41と第1のフランジ部11とに確実に圧接する。よって、実施例1の被覆部材6は外側周縁部41に対するシール性に優れる。同様に、第2の爪部23の外側面(第2当接面23a)と、第2の脚部22の外周面223とがなす角αは90°であるため、第2の圧縮シール部323は内側周縁部51と第2のフランジ部21とに確実に圧接する。よって、実施例1の被覆部材6は内側周縁部51に対するシール性にも優れる。   Furthermore, since the angle α formed by the outer surface (first contact surface 13a) of the first claw portion 13 and the outer peripheral surface 123 of the first leg portion 12 is 90 °, the first claw portion 13 is Surface contact is made with the inner side surface 411 of the outer peripheral edge portion 41. For this reason, the 1st nail | claw part 13 and the 1st flange part 11 press the 1st compression seal part 313 over a wide range. Therefore, the first compression seal portion 313 is securely pressed against the outer peripheral edge portion 41 and the first flange portion 11. Therefore, the covering member 6 of Example 1 is excellent in the sealing performance with respect to the outer peripheral edge portion 41. Similarly, since the angle α formed by the outer surface (second contact surface 23a) of the second claw portion 23 and the outer peripheral surface 223 of the second leg portion 22 is 90 °, the second compression seal portion 323 is in pressure contact with the inner peripheral edge 51 and the second flange 21. Therefore, the covering member 6 of Example 1 is also excellent in the sealing performance with respect to the inner peripheral edge 51.

さらに、第1の規制シール部311は第1の規制連通口122の内部と、第1のフランジ連通口14の内部とに入り込んでいる。このため、外側シール部31は第1の規制部材10から脱離し難い。よって、実施例1の被覆部材6は外側周縁部41に対するシール性に優れる。同様に、第2の規制シール部321は第2の規制連通口222の内部と、第2のフランジ連通口24の内部とに入り込んでいる。このため、内側シール部32は第1の規制部材10から脱離し難い。よって実施例1の被覆部材6は内側周縁部51に対するシール性にも優れる。   Further, the first restriction seal portion 311 enters the inside of the first restriction communication port 122 and the inside of the first flange communication port 14. For this reason, the outer seal portion 31 is unlikely to be detached from the first restricting member 10. Therefore, the covering member 6 of Example 1 is excellent in the sealing performance with respect to the outer peripheral edge portion 41. Similarly, the second restriction seal portion 321 enters the inside of the second restriction communication port 222 and the inside of the second flange communication port 24. For this reason, the inner seal portion 32 is unlikely to be detached from the first restricting member 10. Therefore, the covering member 6 of Example 1 is also excellent in the sealing performance with respect to the inner peripheral edge 51.

さらに、内側シール部32に形成されている管シール部326は、インレットフィラーパイプ7の外周面に圧接する。このため、実施例1の被覆部材6によると、内側シール部32とインレットフィラーパイプ7との隙間を管シール部326によってシールできるため、雨水等の車体内部9への侵入をさらに抑制できる。   Further, the pipe seal portion 326 formed on the inner seal portion 32 is in pressure contact with the outer peripheral surface of the inlet filler pipe 7. For this reason, according to the covering member 6 of the first embodiment, the gap between the inner seal portion 32 and the inlet filler pipe 7 can be sealed by the tube seal portion 326, so that intrusion of rainwater or the like into the vehicle interior 9 can be further suppressed.

さらに、第1の脚本体部120および第2の脚本体部220は略円筒状をなすため、第1の規制部材10および第2の規制部材20(特に第1の脚本体部120および第2の脚本体部220)は径方向および軸方向に変形し難い。このため、実施例1の被覆部材6における第1の規制部材10は、第1の圧縮シール部313および外側周縁部41を安定に挟み込む。第2の規制部材20もまた第2の圧縮シール部323および内側周縁部51を安定に挟み込む。このことによっても、実施例1の被覆部材は外側周縁部41に対するシール性および内側周縁部51に対するシール性に優れる。   Further, since the first leg main body 120 and the second leg main body 220 are substantially cylindrical, the first restricting member 10 and the second restricting member 20 (particularly the first leg main body 120 and the second leg main member 120). The leg main body 220) is not easily deformed in the radial direction and the axial direction. For this reason, the 1st control member 10 in the coating | coated member 6 of Example 1 pinches | interposes the 1st compression seal part 313 and the outer periphery peripheral part 41 stably. The second restricting member 20 also stably sandwiches the second compression seal portion 323 and the inner peripheral edge portion 51. Also by this, the coating | coated member of Example 1 is excellent in the sealing performance with respect to the outer periphery 41, and the sealing performance with respect to the inner periphery 51.

実施例1の被覆部材6を車体に取り付ける作業は、金属製の押圧治具8を用いて行う。実施例1の被覆部材6の取り付け方法を以下に説明する。   The operation of attaching the covering member 6 of Example 1 to the vehicle body is performed using a metal pressing jig 8. A method for attaching the covering member 6 according to the first embodiment will be described below.

図4に示すように、押圧治具8は第1押圧部81と第2押圧部82と連結押圧部83とを持つ。第1押圧部81は略板状をなす。第1押圧部81の外径は第1のフランジ部11の内径よりも大きい。第2押圧部82は略板状をなす。第2押圧部82の外径は第1のフランジ部11の内径よりも小さく、第2のフランジ部21の内径よりも大きい。連結押圧部83はコイルバネからなる。連結押圧部83の一端は第1押圧部81に固着されている。連結押圧部83の他端は第2押圧部82に固着されている。連結押圧部83の外径は第1のフランジ部11の内径よりも小さい。   As shown in FIG. 4, the pressing jig 8 has a first pressing portion 81, a second pressing portion 82, and a connecting pressing portion 83. The first pressing portion 81 has a substantially plate shape. The outer diameter of the first pressing portion 81 is larger than the inner diameter of the first flange portion 11. The second pressing part 82 has a substantially plate shape. The outer diameter of the second pressing portion 82 is smaller than the inner diameter of the first flange portion 11 and larger than the inner diameter of the second flange portion 21. The connection pressing part 83 is made of a coil spring. One end of the connection pressing portion 83 is fixed to the first pressing portion 81. The other end of the connection pressing portion 83 is fixed to the second pressing portion 82. The outer diameter of the connection pressing portion 83 is smaller than the inner diameter of the first flange portion 11.

(準備工程)
押圧治具8の第2押圧部82と連結押圧部83の一部とを被覆部材6の内部に挿入し、第2押圧部82を第2のフランジ部21および第2の規制シール部321の外側に配置する。また、第1押圧部81を第1のフランジ部11および第1の規制シール部311の外側に配置する。このとき、第2押圧部82は第2の規制シール部321の外側面に当接する。第1押圧部81と第1の規制シール部311の外側面とは離間している。
(Preparation process)
The second pressing portion 82 of the pressing jig 8 and a part of the connecting pressing portion 83 are inserted into the covering member 6, and the second pressing portion 82 is inserted into the second flange portion 21 and the second restriction seal portion 321. Place outside. Further, the first pressing portion 81 is disposed outside the first flange portion 11 and the first restriction seal portion 311. At this time, the second pressing portion 82 contacts the outer surface of the second restriction seal portion 321. The first pressing portion 81 and the outer surface of the first restriction seal portion 311 are separated from each other.

(押圧工程)
準備工程終了後、押圧治具8を被覆部材6とともに外側開口40の外側から内側に向けて押圧する。すると、先ず第2押圧部82が第2のフランジ部21を内側に押圧する。第2のフランジ部21が内側に押圧されると、第2のフランジ部21に一体化されている第2の脚部22および第2の爪部23もまた内側に押圧され、内側開口50の内側に押し込まれる。第2の脚部22および第2の爪部23が内側開口50の内側に押し込まれると、第2のフランジ部21と第2の爪部23とが内側周縁部51を挟み込む。
(Pressing process)
After the preparation step, the pressing jig 8 is pressed together with the covering member 6 from the outside of the outer opening 40 toward the inside. Then, first, the second pressing portion 82 presses the second flange portion 21 inward. When the second flange portion 21 is pressed inward, the second leg portion 22 and the second claw portion 23 integrated with the second flange portion 21 are also pressed inward, and the inner opening 50 It is pushed inward. When the second leg portion 22 and the second claw portion 23 are pushed into the inner opening 50, the second flange portion 21 and the second claw portion 23 sandwich the inner peripheral edge portion 51.

連結押圧部83は、第2の脚部22および第2の爪部23が内側開口50の内側に押し込まれるときに、圧縮方向に弾性変形する。すると、第1押圧部81が第1の規制シール部311の外側面に当接し、第1のフランジ部11を内側に押圧する。第1のフランジ部11が内側に押圧されると、第1のフランジ部11に一体化されている第1の脚部12および第1の爪部13もまた内側に押圧され、外側開口40の内側に押し込まれる。第1の脚部12および第1の爪部13が外側開口40の内側に押し込まれると、第1のフランジ部11と第1の爪部13とが外側周縁部41を挟み込む。   The connection pressing portion 83 is elastically deformed in the compression direction when the second leg portion 22 and the second claw portion 23 are pushed into the inner opening 50. Then, the 1st press part 81 contact | abuts to the outer surface of the 1st control seal | sticker part 311, and presses the 1st flange part 11 inside. When the first flange portion 11 is pressed inward, the first leg portion 12 and the first claw portion 13 integrated with the first flange portion 11 are also pressed inward, and the outer opening 40 It is pushed inward. When the first leg portion 12 and the first claw portion 13 are pushed inside the outer opening 40, the first flange portion 11 and the first claw portion 13 sandwich the outer peripheral edge portion 41.

実施例1の被覆部材6の取り付け方法によると、被覆部材6を外側周縁部41に取り付ける工程と、被覆部材6を内側周縁部51に取り付ける工程と、を一工程(押圧工程)にすることができる。よって、実施例1の被覆部材6の取り付け方法は、取り付け作業性に優れる。   According to the method for attaching the covering member 6 of the first embodiment, the step of attaching the covering member 6 to the outer peripheral edge portion 41 and the step of attaching the covering member 6 to the inner peripheral edge portion 51 are made into one step (pressing step). it can. Therefore, the attachment method of the covering member 6 of Example 1 is excellent in attachment workability.

さらに、第1の爪部13はシール部材3で覆われていないため、第1の爪部13を外側開口40に圧入する際の抵抗は小さくて済む。第2の爪部23もまたシール部材3で覆われていないため、第2の爪部23を内側開口50に圧入する際の抵抗は小さくて済む。よって実施例1の被覆部材6は、車体への取り付け作業性に優れる。   Further, since the first claw portion 13 is not covered with the seal member 3, the resistance when the first claw portion 13 is press-fitted into the outer opening 40 may be small. Since the 2nd nail | claw part 23 is also not covered with the sealing member 3, the resistance at the time of press-fitting the 2nd nail | claw part 23 in the inner side opening 50 may be small. Therefore, the covering member 6 of Example 1 is excellent in workability for attachment to the vehicle body.

実施例1の被覆部材6における第1の規制部材10および第2の規制部材20は樹脂材料であるPPからなるが、本発明の被覆部材6における第1の規制部材10および第2の規制部材20の材料は、これに限定されない。本発明の被覆部材6における第1の規制部材10および第2の規制部材20はシール部材3よりも硬質の材料からなる。第1の規制部材10および第2の規制部材20の材料としては、PP等の樹脂材料が好ましく用いられるが、マグネシウム、アルミニウム、鉄等の金属材料を用いても良い。シール部材3は弾性材料からなる。シール部材3の材料としては、ゴムやエラストマおよびこれらを含む混合材料等が好ましく用いられる。   The first restricting member 10 and the second restricting member 20 in the covering member 6 of the first embodiment are made of PP which is a resin material, but the first restricting member 10 and the second restricting member in the covering member 6 of the present invention. The 20 materials are not limited to this. The first restricting member 10 and the second restricting member 20 in the covering member 6 of the present invention are made of a material harder than the seal member 3. As materials for the first regulating member 10 and the second regulating member 20, resin materials such as PP are preferably used, but metal materials such as magnesium, aluminum, and iron may be used. The seal member 3 is made of an elastic material. As the material of the seal member 3, rubber, elastomer, a mixed material containing these, or the like is preferably used.

実施例1の被覆部材6は第1のリップ315と第2のリップ325とを持つが、本発明の被覆部材6は第1のリップ315および第2のリップ325を持たなくても良い。好ましくは、第1の圧縮シール部323には外側周縁部41の外側面410に圧接しかつ線接触する部分を設けるのが良く、第2の圧縮シール部323には内側周縁部51の外側面510に圧接しかつ線接触する部分を設けるのが良い。   Although the covering member 6 of the first embodiment has the first lip 315 and the second lip 325, the covering member 6 of the present invention may not have the first lip 315 and the second lip 325. Preferably, the first compression seal portion 323 may be provided with a portion that is in pressure contact with the outer surface 410 of the outer peripheral edge portion 41 and is in line contact, and the second compression seal portion 323 is provided with an outer surface of the inner peripheral edge portion 51.

Specifically, the first restriction seal portion 311 enters the first restriction communication port 122 and continues to the inner peripheral end of the first compression seal portion 313 through the first restriction communication port 122.

内側シール部32は、第2の圧縮シール部323と第2の規制シール部321とを持つ。第2の圧縮シール部323は第2のフランジ部21の内側面210を覆う。第2の圧縮シール部323は、実施例1の被覆部材6における第2の圧縮シール部と略同形状である。第2の規制シール部321は、第2の圧縮シール部323に連続している。第2の規制シール部321は第2の脚部22の内周面224を覆う。詳しくは、第2の規制シール部321は第2の規制連通口222の内部に延び、第2の規制連通口222を通じて第2の圧縮シール部323の内周側端部に連続する。   The inner seal portion 32 has a second compression seal portion 323 and a second restriction seal portion 321. The second compression seal portion 323 covers the inner surface 210 of the second flange portion 21. The second compression seal portion 323 has substantially the same shape as the second compression seal portion in the covering member 6 of the first embodiment. The second restriction seal portion 321 is continuous with the second compression seal portion 323. The second restriction seal portion 321 covers the inner peripheral surface 224 of the second leg portion 22. Specifically, the second restriction seal portion 321 extends into the second restriction communication port 222 and continues to the inner peripheral side end of the second compression seal portion 323 through the second restriction communication port 222.

実施例2の被覆部材6における第1の規制部材10および第2の規制部材20はPPからなり、シール部材3はPPとTPO(オレフィン系熱可塑性エラストマ)との混合材料からなる。シール部材3はPPを含むため、第1の規制部材10および第2の規制部材20と融着可能である。また、実施例2の被覆部材6におけるシール部材3と、第1の規制部材10と、第2の規制部材20とはインサート成形(一体成形)されている。このため、シール部材3と第1の規制部材10と第2の規制部材20とは、融着して一体化している。さらに、第1の規制シール部311は第1の規制連通口122の内部に入り込み、第2の規制シール部321は第2の規制連通口222の内部に入り込んでいる。このため、シール部材3と第1の規制部材10と第2の規制部材20とは強固に一体化されている。よって、実施例2の被覆部材6におけるシール部材3は第1の規制部材10および第2の規制部材20から脱離し難い。よって、実施例2の被覆部材6は外側周縁部41に対するシール性と内側周縁部51に対するシール性とにより一層優れ、雨水等の車体内部9への侵入をより一層抑制できる。   The first restricting member 10 and the second restricting member 20 in the covering member 6 of the second embodiment are made of PP, and the seal member 3 is made of a mixed material of PP and TPO (olefin-based thermoplastic elastomer). Since the seal member 3 includes PP, the seal member 3 can be fused to the first restriction member 10 and the second restriction member 20. Further, the seal member 3, the first restricting member 10, and the second restricting member 20 in the covering member 6 of the second embodiment are insert-molded (integrally formed). For this reason, the seal member 3, the first regulating member 10, and the second regulating member 20 are fused and integrated. Further, the first restriction seal portion 311 enters the inside of the first restriction communication port 122, and the second restriction seal portion 321 enters the inside of the second restriction communication port 222. For this reason, the seal member 3, the first restricting member 10, and the second restricting member 20 are firmly integrated. Therefore, the sealing member 3 in the covering member 6 of Example 2 is difficult to be detached from the first restricting member 10 and the second restricting member 20. Therefore, the covering member 6 according to the second embodiment is more excellent in the sealing performance with respect to the outer peripheral edge portion 41 and the sealing performance with respect to the inner peripheral edge portion 51 and can further suppress the intrusion of rainwater or the like into the vehicle body interior 9.

さらに、第1の圧縮シール部313は第1のフランジ部11の内側面110に融着している。このため、実施例2の被覆部材6は、第1の規制シール部311で第1のフランジ部11の外周面111や外側面112を覆わなくても、シール部材3と第1のフランジ部11とが強固に一体化する。第2の圧縮シール部323もまた第2のフランジ部21の内側面210に融着している。このため、実施例2の被覆部材6は、第2の規制シール部321で第2のフランジ部21の外周面211や外側面212を覆わなくても、シール部材3と第2のフランジ部21とが強固に一体化する。よって、実施例2の被覆部材6は、軽量化でき、かつ安価に製造できる。   Further, the first compression seal portion 313 is fused to the inner side surface 110 of the first flange portion 11. For this reason, the covering member 6 of Example 2 does not cover the outer peripheral surface 111 and the outer surface 112 of the first flange portion 11 with the first restriction seal portion 311, and the seal member 3 and the first flange portion 11. Are firmly integrated. The second compression seal portion 323 is also fused to the inner surface 210 of the second flange portion 21. For this reason, the covering member 6 of Example 2 does not cover the outer peripheral surface 211 and the outer surface 212 of the second flange portion 21 with the second restriction seal portion 321, and the seal member 3 and the second flange portion 21. Are firmly integrated. Therefore, the covering member 6 of Example 2 can be reduced in weight and manufactured at low cost.

実施例3の被覆部材6は、実施例1の被覆部材と同様に、外側周縁部41に対するシール性および内側周縁部51に対するシール性に優れ、雨水等の車体内部9への侵入を抑制できる。   Similar to the covering member of the first embodiment, the covering member 6 of the third embodiment is excellent in the sealing performance with respect to the outer peripheral edge portion 41 and the sealing performance with respect to the inner peripheral edge portion 51, and can suppress intrusion of rainwater or the like into the vehicle body interior 9.

実施例1〜実施例3の被覆部材6は、何れも第2の規制部材20および内側シール部32を持つが、本発明の被覆部材6は第2の規制部材20および内側シール部32を持たなくても良い。すなわち、本発明の被覆部材6は、内側周縁部51に取り付けなくても良い。例えば、燃料タンクが内側周縁部51の外側に配設されている場合など、車体に内側開口50が形成されていない場合には、第1の規制部材10と外側シール部31とを外側周縁部41に取り付けるとともに、外側シール部31の内周側に管シール部326を形成すればよい。この場合には、管シール部326がインレットフィラーパイプ7に圧接してシール部材3とインレットフィラーパイプ7との隙間をシールするため、車体内部9に雨水等が侵入するおそれはない。よって、この場合には第2の規制部材20、内側シール部32および連結シール部33は不要である。   Each of the covering members 6 of the first to third embodiments has the second restricting member 20 and the inner seal portion 32, but the covering member 6 of the present invention has the second restricting member 20 and the inner seal portion 32. It is not necessary. That is, the covering member 6 of the present invention may not be attached to the inner peripheral edge 51. For example, when the inner opening 50 is not formed in the vehicle body, such as when the fuel tank is disposed outside the inner peripheral edge 51, the first restricting member 10 and the outer seal part 31 are connected to the outer peripheral edge. The pipe seal portion 326 may be formed on the inner peripheral side of the outer seal portion 31 while being attached to 41. In this case, since the pipe seal portion 326 is pressed against the inlet filler pipe 7 and seals the gap between the seal member 3 and the inlet filler pipe 7, there is no possibility that rainwater or the like enters the vehicle body interior 9. Therefore, in this case, the second restricting member 20, the inner seal portion 32, and the connection seal portion 33 are unnecessary.

なお、実施例1〜実施例3の被覆部材6は、第1のフランジ部21と第1の脚部12と第1の爪部13とを一体形成しているが、これらの一部を別体で形成して一体化しても良い。同様に、第2のフランジ部21と第2の脚部22と第2の爪部23との一部を別体で形成しても良い。   In addition, although the coating | coated member 6 of Example 1- Example 3 has integrally formed the 1st flange part 21, the 1st leg part 12, and the 1st nail | claw part 13, these parts are different. It may be formed by a body and integrated. Similarly, a part of the second flange portion 21, the second leg portion 22, and the second claw portion 23 may be formed separately.
