　本開示は、車両用外装部品のシール構造に関する。 The present disclosure relates to a seal structure for vehicle exterior parts.
　特許文献１には、自動車用ドアミラー（以下、ドアミラー）が開示されている。このドアミラーは、フロントドアに固定されるベース部材と、ベース部材に取り付けられるミラーハウジングとを備えている。ミラーハウジングには、ミラー本体が取り付けられている。 Patent Document 1 discloses an automobile door mirror (hereinafter referred to as a door mirror). This door mirror includes a base member fixed to the front door and a mirror housing attached to the base member. A mirror body is attached to the mirror housing.
　ベース部材は、フロントドアの側面視略三角形の隅部形状に合わせて側面視略三角形状である。ベース部材は、硬質の合成樹脂製である。ベース部材の背面には、環状のリブ壁が突設されている。 The base member has a substantially triangular shape in side view to match the corner shape of the front door, which is substantially triangular in side view. The base member is made of hard synthetic resin. An annular rib wall protrudes from the back surface of the base member.
　ベース部材は、フロントドアのミラー取付部にガスケットを介して固定されている。ガスケットは、ポリエチレンなどの軟質の合成樹脂製である。ガスケットは、リブ壁の先端に接触している。ガスケットの背面には、スポンジゴム製のシール材が接着固定されている。このシール材が、フロントドアのサッシュレインフォースとガスケットとによって挟まれることで圧縮されている。 The base member is fixed to the mirror mounting part of the front door via a gasket. The gasket is made of soft synthetic resin such as polyethylene. A gasket contacts the tip of the rib wall. A sealing material made of sponge rubber is adhered and fixed to the back surface of the gasket. This sealing material is compressed by being sandwiched between the sash reinforcement of the front door and the gasket.
　こうしたドアミラーにおいては、ベース部材の環状リブによって、ガスケット及びシール材がサッシュレインフォースに向けて押圧されている。これにより、ガスケットとフロントドアとの間のシール圧が高められている。 In such a door mirror, the annular rib of the base member presses the gasket and sealing material toward the sash reinforcement. This increases the sealing pressure between the gasket and the front door.

　こうしたドアミラーのシール構造においては、ガスケットとは別体のシール材が設けられている。そのため、部品点数が多くなるという問題がある。 In this door mirror sealing structure, a sealing material separate from the gasket is provided. Therefore, there is a problem that the number of parts increases.
　なお、こうした問題は、上述したドアミラーのシール構造に限られるものではなく、車両の対象部位を覆うように設けられるベース部材と、ガスケットとを備える車両用外装部品のシール構造においては、共通して生じる。 Such a problem is not limited to the sealing structure of the door mirror described above, but is common to the sealing structure of the vehicle exterior part provided with the base member provided so as to cover the target portion of the vehicle and the gasket. occur.
　上記課題を解決するための車両用外装部品のシール構造は、車両の対象部位を覆うように設けられて車両用外装部品を構成するベース部材と、樹脂製のガスケットと、を備えている。前記ガスケットは、前記対象部位と前記ベース部材との間に設けられる本体部と、板状の折り返し部と、前記本体部と前記折り返し部との間に設けられて前記本体部に対して前記折り返し部を回動可能に連結するヒンジ部と、を有している。前記折り返し部は、前記ヒンジ部を起点として前記本体部と重なるように折り返されており、前記対象部位に対して接触することで前記対象部位との間をシールする突条を有している。 A seal structure for a vehicle exterior component for solving the above problems includes a base member that is provided to cover a target portion of the vehicle and constitutes the vehicle exterior component, and a resin gasket. The gasket includes: a main body portion provided between the target portion and the base member; and a hinge portion pivotally connecting the portions. The folded portion is folded back so as to overlap with the main body portion starting from the hinge portion, and has a ridge that seals with the target portion by coming into contact with the target portion.
　同構成によれば、ガスケットの折り返し部が、ヒンジ部を起点として折り返されることで本体部と重なっている。そして、折り返し部に設けられた突条が車両の対象部位に対して接触することでガスケットと対象部位との間がシールされる。 According to the same configuration, the folded portion of the gasket overlaps the main body portion by folding back with the hinge portion as the starting point. Then, the ridges provided on the folded portion come into contact with the target portion of the vehicle, thereby sealing between the gasket and the target portion.
　このように、ガスケットの本体部と折り返し部とがヒンジ部を介して一体に形成されているため、ガスケットとは別体のシール材を省略することができる。また、突条が、本体部に対してヒンジ部を介して連結された折り返し部に設けられているため、突条の形状の自由度及び寸法精度を高めることができる。 In this way, since the main body portion and the folded portion of the gasket are integrally formed via the hinge portion, a sealing material separate from the gasket can be omitted. In addition, since the ridges are provided in the folded portion that is connected to the main body via the hinge portion, it is possible to increase the flexibility and dimensional accuracy of the shape of the ridges.
　したがって、シール性を確保しつつ、部品点数を低減することができる。 Therefore, it is possible to reduce the number of parts while ensuring sealing performance.
　上記車両用外装部品のシール構造において、前記折り返し部における前記突条とは反対側の面には、凹溝が設けられており、前記突条は、前記凹溝によって中空となっていることが好ましい。 In the seal structure for the vehicle exterior component, a concave groove is provided on a surface of the folded portion opposite to the ridge, and the ridge is hollow due to the concave groove. preferable.
　同構成によれば、突条及び凹溝の各々の形状や大きさに応じて、車両の対象部位から受ける突条の弾性反発力を容易に変更することができる。したがって、突条によるシール圧の設定の自由度を高めることができる。 According to this configuration, it is possible to easily change the elastic repulsive force of the ridges received from the target portion of the vehicle according to the shape and size of each of the ridges and the grooves. Therefore, it is possible to increase the degree of freedom in setting the sealing pressure by the ridges.
　また、上記構成によれば、折り返し部において突条が設けられている部分の板厚が部分的に大きくなることを抑制できる。これにより、ヒケなどの成形不良の発生を抑制できるため、突条の寸法精度を一層高めることができる。 In addition, according to the above configuration, it is possible to suppress a partial increase in the plate thickness of the portion where the protrusion is provided in the folded portion. As a result, it is possible to suppress the occurrence of molding defects such as sink marks, so that the dimensional accuracy of the protrusions can be further improved.
　上記車両用外装部品のシール構造において、前記突条は、前記対象部位に向かって先細状の断面形状を有していることが好ましい。 In the seal structure for the vehicle exterior component, it is preferable that the ridge has a cross-sectional shape that tapers toward the target portion.
　同構成によれば、突条の接触面積が小さくなるため、突条によるシール圧が高められるようになる。したがって、ガスケットと対象部位との間のシール性を向上できる。 According to this configuration, the contact area of the ridges is reduced, so the sealing pressure by the ridges can be increased. Therefore, it is possible to improve the sealing performance between the gasket and the target portion.
　上記車両用外装部品のシール構造において、前記本体部は、第１係合部を有しており、前記折り返し部は、前記本体部に対して前記折り返し部が重なっている状態において前記第１係合部に係合する第２係合部を有していることが好ましい。 In the above seal structure for a vehicle exterior component, the main body portion has a first engaging portion, and the folded portion is configured to engage the first engaging portion when the folded portion overlaps the main body portion. It is preferable to have a second engagement portion that engages the junction.
　同構成によれば、本体部の第１係合部と折り返し部の第２係合部とが係合することにより、本体部に対して折り返し部が重なっている状態が保持されるようになる。したがって、簡単な構成によって、本体部に対して折り返し部が重なっている状態を保持することができる。 According to this configuration, the first engaging portion of the main body portion and the second engaging portion of the folded portion are engaged with each other, so that the state in which the folded portion overlaps the main body portion is maintained. . Therefore, it is possible to maintain the state in which the folded portion overlaps the main body portion with a simple configuration.
　上記車両用外装部品のシール構造において、前記対象部位は、前記ガスケットよりも軟質な軟質部材を含み、前記突条は、前記軟質部材に対して接触することで前記軟質部材との間をシールしていることが好ましい。 In the seal structure for vehicle exterior parts, the target portion includes a soft member that is softer than the gasket, and the ridge seals with the soft member by coming into contact with the soft member. preferably.
　同構成によれば、対象部位を構成する軟質部材がガスケットよりも軟質であるため、突条が軟質部材に対して食い込みやすくなる。したがって、ガスケットと軟質部材との間のシール性を向上できる。 According to this configuration, since the soft member that constitutes the target portion is softer than the gasket, the ridges can easily bite into the soft member. Therefore, it is possible to improve the sealing performance between the gasket and the soft member.
　上記車両用外装部品のシール構造において、前記ベース部材は、硬質樹脂製であり、前記本体部は、前記折り返し部と重なり合う板部と、前記板部から前記ベース部材の内面に向かって突出する突出部とを有しており、前記突出部は、前記ベース部材の内面に対して面接触していることが好ましい。 In the seal structure for vehicle exterior parts, the base member is made of a hard resin, and the main body includes a plate portion that overlaps the folded portion and a protrusion that protrudes from the plate portion toward the inner surface of the base member. It is preferable that the protruding portion is in surface contact with the inner surface of the base member.
　同構成によれば、ガスケットの突出部がベース部材の内面に面接触することで、ベース部材及びガスケットの剛性を互いに高めることができる。これにより、突条によるシール圧を高めることができる。したがって、ガスケットと対象部位との間のシール性を向上できる。 According to this configuration, the protruding portion of the gasket is in surface contact with the inner surface of the base member, so that the rigidity of the base member and the gasket can be enhanced. Thereby, the sealing pressure by the protrusion can be increased. Therefore, it is possible to improve the sealing performance between the gasket and the target portion.
　また、上記構成によれば、ベース部材及びガスケットの剛性を互いに高めるためにベース部材の内面に設けられるリブの高さを小さくできる、あるいは当該リブを省略できる。したがって、ベース部材の内面にリブを設定することに起因してベース部材の意匠面にヒケなどの成形不良が発生することを抑制することができる。 Further, according to the above configuration, the height of the rib provided on the inner surface of the base member can be reduced or the rib can be omitted in order to increase the rigidity of the base member and the gasket. Therefore, it is possible to suppress the occurrence of molding defects such as sink marks on the design surface of the base member due to setting the ribs on the inner surface of the base member.
　上記車両用外装部品のシール構造において、前記突出部は、前記板部の板厚方向において前記突条と重なり合う位置に設けられていることが好ましい。 In the seal structure of the vehicle exterior component, it is preferable that the protruding portion is provided at a position overlapping with the ridge in the plate thickness direction of the plate portion.
　同構成によれば、ガスケットのうち突条が設けられている部分の剛性が突出部によって的確に高められる。これにより、突条によるシール圧を一層高めることができる。したがって、ガスケットと対象部位との間のシール性を一層向上できる。 According to the same configuration, the rigidity of the portion of the gasket where the protrusion is provided is appropriately increased by the projecting portion. Thereby, the sealing pressure by the protrusion can be further increased. Therefore, it is possible to further improve the sealing performance between the gasket and the target portion.
　上記車両用外装部品のシール構造において、前記ベース部材の内面と前記突出部とは、凹凸の関係により位置決めされていることが好ましい。 In the seal structure of the vehicle exterior component, it is preferable that the inner surface of the base member and the projecting portion are positioned by an uneven relationship.
　同構成によれば、ベース部材の内面とガスケットの突出部とが、凹凸の関係により位置決めされている。これにより、ベース部材の内面とガスケットの突出部とが面接触している状態が保持される。したがって、ベース部材及びガスケットの剛性を互いに高めることができるといった効果をより確実に奏することができる。 According to this configuration, the inner surface of the base member and the projecting portion of the gasket are positioned according to the uneven relationship. As a result, the state in which the inner surface of the base member and the projecting portion of the gasket are in surface contact is maintained. Therefore, the effect of increasing the rigidity of the base member and the gasket can be achieved more reliably.
　上記車両用外装部品のシール構造において、前記車両用外装部品は、車両のアウタミラーであり、前記対象部位は、車両のフロントドアに設けられていることが好ましい。 In the seal structure for the vehicle exterior component, it is preferable that the vehicle exterior component is an outer mirror of the vehicle, and the target portion is provided on the front door of the vehicle.
　同構成によれば、車両のアウタミラーのシール性を確保しつつ、部品点数を低減することができる。 According to the same configuration, it is possible to reduce the number of parts while ensuring the sealing performance of the vehicle's outer mirror.
　本開示によれば、シール性を確保しつつ、部品点数を低減することができる。 According to the present disclosure, it is possible to reduce the number of parts while ensuring sealing performance.

　この状態において、ドアレインフォース８３の内側から、図示しないボルトが、ベース本体１２の雌ねじ部１３ｂに螺入されることによって、アウタミラー１０がフロントドア８０に取り付けられている。 In this state, the outer mirror 10 is attached to the front door 80 by screwing a bolt (not shown) into the female screw portion 13b of the base body 12 from the inside of the door reinforcement 83 .
　ガスケット２０の突条２６は、ガラスラン３０の保持部３１に対して接触している。このことにより、突条２６は、折り返し部２５とガラスラン３０との間をシールしている。 The ridge 26 of the gasket 20 is in contact with the holding portion 31 of the glass run 30 . As a result, the protrusion 26 seals between the folded portion 25 and the glass run 30 .
　なお、本実施形態におけるドアレインフォース８３及びガラスラン３０が、本開示に係る車両の対象部位に相当する。また、ガラスラン３０が本開示に係る軟質部材に相当する。すなわち、本実施形態では、車両の対象部位は軟質部材を含む。また、第１係合突起２４Ａ及び第１係合孔２４Ｂが本開示における第１係合部に相当する。また、第２係合孔２８Ａ及び第２係合突起２８Ｂが本開示における第２係合部に相当する。 It should be noted that the door reinforcement 83 and the glass run 30 in this embodiment correspond to target parts of the vehicle according to the present disclosure. Also, the glass run 30 corresponds to the soft member according to the present disclosure. That is, in this embodiment, the target portion of the vehicle includes the soft member. Also, the first engaging protrusion 24A and the first engaging hole 24B correspond to the first engaging portion in the present disclosure. Also, the second engaging hole 28A and the second engaging protrusion 28B correspond to the second engaging portion in the present disclosure.
　本実施形態の作用効果について説明する。 The effects of this embodiment will be explained.
　（１）ガスケット２０の折り返し部２５が、ヒンジ部２９を起点として折り返されることで本体部２１と重なっている。そして、折り返し部２５に設けられた突条２６が、ガラスラン３０の保持部３１に対して接触することで、折り返し部２５とガラスラン３０との間がシールされる。 (1) The folded portion 25 of the gasket 20 overlaps the main body portion 21 by folding back with the hinge portion 29 as a starting point. The protrusion 26 provided on the folded portion 25 contacts the holding portion 31 of the glass run 30 , thereby sealing the space between the folded portion 25 and the glass run 30 .
　このように、ガスケット２０の本体部２１と折り返し部２５とがヒンジ部２９を介して一体に形成されているため、ガスケット２０とは別体のシール材を省略することができる。また、突条２６が、本体部２１に対してヒンジ部２９を介して連結された折り返し部２５に設けられているため、突条２６の形状の自由度及び寸法精度を高めることができる。 As described above, since the main body portion 21 and the folded portion 25 of the gasket 20 are integrally formed via the hinge portion 29, a sealing material separate from the gasket 20 can be omitted. Moreover, since the ridges 26 are provided on the folded portion 25 connected to the main body 21 via the hinge portion 29, the degree of freedom in the shape of the ridges 26 and the dimensional accuracy can be enhanced.
　したがって、シール性を確保しつつ、部品点数を低減することができる。 Therefore, it is possible to reduce the number of parts while ensuring sealing performance.
　（２）折り返し部２５における突条２６とは反対側の面には、凹溝２７が設けられており、突条２６は、凹溝２７によって中空となっている。 (2) A recessed groove 27 is provided on the surface of the folded portion 25 opposite to the protrusion 26 , and the protrusion 26 is hollow due to the recessed groove 27 .
　こうした構成によれば、突条２６及び凹溝２７の各々の形状や大きさに応じて、ガラスラン３０から受ける突条２６の弾性反発力を容易に変更することができる。したがって、突条２６によるシール圧の設定の自由度を高めることができる。 With such a configuration, the elastic repulsive force of the ridges 26 received from the glass run 30 can be easily changed according to the shape and size of each of the ridges 26 and the grooves 27 . Therefore, the degree of freedom in setting the sealing pressure by the protrusion 26 can be increased.
　また、上記構成によれば、折り返し部２５において突条２６が設けられている部分の板厚が部分的に大きくなることを抑制できる。これにより、ヒケなどの成形不良の発生を抑制できるため、突条２６の寸法精度を一層高めることができる。 Further, according to the above configuration, it is possible to suppress a partial increase in the plate thickness of the portion where the protrusion 26 is provided in the folded portion 25 . As a result, it is possible to suppress the occurrence of molding defects such as sink marks, so that the dimensional accuracy of the protrusions 26 can be further improved.
　（３）突条２６は、ガラスラン３０に向かって先細状の断面形状を有している。 (3) The ridge 26 has a tapered cross-sectional shape toward the glass run 30 .
　こうした構成によれば、突条２６の接触面積が小さくなるため、突条２６によるシール圧が高められるようになる。したがって、ガスケット２０とガラスラン３０との間のシール性を向上できる。 With such a configuration, the contact area of the ridges 26 is reduced, so that the sealing pressure by the ridges 26 can be increased. Therefore, the sealing performance between the gasket 20 and the glass run 30 can be improved.
　（４）本体部２１は、第１係合突起２４Ａを有しており、折り返し部２５は、本体部２１に対して折り返し部２５が重なっている状態において第１係合突起２４Ａに係合する第２係合孔２８Ａを有している。 (4) The body portion 21 has a first engagement projection 24A, and the folded portion 25 is engaged with the first engagement projection 24A in a state where the folded portion 25 overlaps the body portion 21. It has a second engagement hole 28A.
　こうした構成によれば、本体部２１の第１係合突起２４Ａと折り返し部２５の第２係合孔２８Ａとが係合することにより、本体部２１に対して折り返し部２５が重なっている状態が保持されるようになる。したがって、簡単な構成によって、本体部２１に対して折り返し部２５が重なっている状態を保持することができる。 According to such a configuration, the first engagement protrusion 24A of the body portion 21 and the second engagement hole 28A of the folded portion 25 are engaged with each other, thereby preventing the folded portion 25 from overlapping the body portion 21. will be retained. Therefore, it is possible to maintain the state in which the folded portion 25 overlaps the main body portion 21 with a simple configuration.
　（５）ガラスラン３０は、ガスケット２０よりも軟質な軟質部材により構成されており、突条２６は、ガラスラン３０に対して接触することでガラスラン３０との間をシールしている。 (5) The glass run 30 is made of a softer material than the gasket 20 , and the protrusion 26 contacts the glass run 30 to seal the glass run 30 .
　こうした構成によれば、ガラスラン３０を構成する軟質部材がガスケット２０よりも軟質であるため、突条２６がガラスラン３０に対して食い込みやすくなる。したがって、ガスケット２０とガラスラン３０との間のシール性を向上できる。 With such a configuration, the soft member that constitutes the glass run 30 is softer than the gasket 20 , so the ridges 26 can easily bite into the glass run 30 . Therefore, the sealing performance between the gasket 20 and the glass run 30 can be improved.
　（６）ベース部材１１は、硬質樹脂製である。また、本体部２１は、折り返し部２５と重なり合う板部２２と、板部２２からベース部材１１の内面に向かって突出する突出部２３Ａ，２３Ｂ，２３Ｃを有している。突出部２３Ａ，２３Ｂ，２３Ｃは、ベース部材１１の内面に対して面接触している。 (6) The base member 11 is made of hard resin. Further, the body portion 21 has a plate portion 22 overlapping the folded portion 25 and projecting portions 23A, 23B, and 23C projecting from the plate portion 22 toward the inner surface of the base member 11 . The protrusions 23A, 23B, and 23C are in surface contact with the inner surface of the base member 11 .
　こうした構成によれば、突出部２３Ａ，２３Ｂ，２３Ｃがベース部材１１の内面に面接触することで、ベース部材１１及びガスケット２０の剛性を互いに高めることができる。これにより、突条２６によるシール圧を高めることができる。したがって、ガスケット２０とガラスラン３０との間のシール性を向上できる。 According to such a configuration, the protruding portions 23A, 23B, and 23C are in surface contact with the inner surface of the base member 11, so that the rigidity of the base member 11 and the gasket 20 can be enhanced. Thereby, the sealing pressure by the protrusion 26 can be increased. Therefore, the sealing performance between the gasket 20 and the glass run 30 can be improved.
　また、上記構成によれば、ベース部材１１及びガスケット２０の剛性を互いに高めるためにベース部材１１の内面に設けられるリブを省略できる。したがって、ベース部材１１の内面にリブを設定することに起因してベース部材１１の意匠面にヒケなどの成形不良が発生することを抑制することができる。 Further, according to the above configuration, the ribs provided on the inner surface of the base member 11 can be omitted in order to increase the rigidity of the base member 11 and the gasket 20 together. Therefore, it is possible to suppress the occurrence of molding defects such as sink marks on the design surface of the base member 11 due to setting the ribs on the inner surface of the base member 11 .
　（７）第２突出部２３Ｂは、板部２２の板厚方向において突条２６と重なり合う位置に設けられている。 (7) The second protruding portion 23B is provided at a position overlapping the ridge 26 in the plate thickness direction of the plate portion 22 .
　こうした構成によれば、ガスケット２０のうち突条２６が設けられている部分の剛性が第２突出部２３Ｂによって的確に高められる。これにより、突条２６によるシール圧を一層高めることができる。したがって、ガスケット２０とガラスラン３０との間のシール性を一層向上できる。 According to such a configuration, the rigidity of the portion of the gasket 20 where the protrusion 26 is provided is appropriately increased by the second projecting portion 23B. Thereby, the sealing pressure by the protrusion 26 can be further increased. Therefore, the sealing performance between the gasket 20 and the glass run 30 can be further improved.
　（８）第２突出部２３Ｂに設けられた位置決め凹部２３１と、ベース部材１１の内面に設けられた位置決め凸部１８とが嵌合している。 (8) The positioning concave portion 231 provided on the second protruding portion 23B and the positioning convex portion 18 provided on the inner surface of the base member 11 are fitted.
　こうした構成によれば、ベース部材１１の内面とガスケット２０の第２突出部２３Ｂとが面接触している状態が保持される。したがって、ベース部材１１及びガスケット２０の剛性を互いに高めることができるといった効果をより確実に奏することができる。 According to such a configuration, the state in which the inner surface of the base member 11 and the second projecting portion 23B of the gasket 20 are in surface contact is maintained. Therefore, the effect of increasing the rigidity of the base member 11 and the gasket 20 can be achieved more reliably.
