Abstract

PROBLEM TO BE SOLVED: To provide a technology which locks a long-length resin member to a vehicle body by regulating the movement of the resin member in a direction orthogonal to a longitudinal direction of the resin member, and can absorb the elongation of the resin member caused by thermal expansion in the longitudinal direction of the resin member, in a resin member attachment structure which attaches the long-length resin member to the vehicle body.SOLUTION: When a resin member 30 is elongated in a vehicle width direction by thermal expansion, a lock face 62 maintains an abutment state on a lock end face 43, and an attachment part 40 moves as an arrow a. An attachment part 50 does not move in a vehicle body fore-and-aft direction, but can move to only in the vehicle width direction. That is, a position of the resin member 30 in a fore-and-aft direction with respect to a vehicle body is held, and only the elongation of the resin member 30 in the vehicle width direction can be absorbed.

Description

本発明は、長尺の樹脂部材を車体に取り付ける樹脂部材取付構造の改良に関する。   The present invention relates to an improvement in a resin member mounting structure for mounting a long resin member to a vehicle body.

自動車の車体には、装飾用の部品が取り付けられる。装飾用の部品には樹脂製のものがあり、この樹脂部材を金属製の車体に取り付ける技術として、クリップを用いた技術が知られている（例えば、特許文献１（図１）参照。）。   A decorative part is attached to the body of an automobile. Some decorative parts are made of resin, and as a technique for attaching the resin member to a metal vehicle body, a technique using a clip is known (for example, see Patent Document 1 (FIG. 1)).

この特許文献１に示される技術は、車体を構成する金属製の車体パネルに矩形状の取付孔を設け、この取付孔にクリップの一端を係止する。取付孔とクリップの間には隙間が無く、クリップは車体パネルに対して固定される。クリップの他端には、車体パネルに重ねられる基部と、この基部に設けられる円柱状の軸部と、この軸部の先端に設けられるフランジ部とが形成されている。   In the technique disclosed in Patent Document 1, a rectangular mounting hole is provided in a metal vehicle body panel constituting a vehicle body, and one end of a clip is locked in the mounting hole. There is no gap between the mounting hole and the clip, and the clip is fixed to the vehicle body panel. At the other end of the clip, a base portion that is overlaid on the vehicle body panel, a columnar shaft portion that is provided at the base portion, and a flange portion that is provided at the tip of the shaft portion are formed.

樹脂部材の裏面には、クリップを嵌め込む装着部が設けられている。クリップの軸部を、装着部の導入溝に導入すると、装着部の抜け止め縁にフランジ部が引っ掛かり、樹脂部材が車体に取り付けられる。導入溝の嵌め込み方向の奥には、導入溝の幅よりも大きい径の円形状の穴が形成されている。この穴の径は、クリップの軸部の外径よりも大きいので、穴に対して軸部ができる。結果、クリップに対して樹脂部材は所定量の移動が可能となる。   A mounting portion into which a clip is fitted is provided on the back surface of the resin member. When the shaft portion of the clip is introduced into the introduction groove of the mounting portion, the flange portion is caught by the retaining edge of the mounting portion, and the resin member is attached to the vehicle body. A circular hole having a diameter larger than the width of the introduction groove is formed at the back in the fitting direction of the introduction groove. Since the diameter of the hole is larger than the outer diameter of the shaft portion of the clip, a shaft portion is formed with respect to the hole. As a result, the resin member can move a predetermined amount with respect to the clip.

樹脂部材の成形状態や取付状態によっては、嵌め込み方向の最も奥で、クリップの軸部が穴に当接することがある。嵌め込み方向に対して直交する方向（嵌め込み直交方向）に樹脂部材が長尺の場合、樹脂部材は熱膨張によって長手方向に伸びようとする。しかし、軸部が嵌め込み方向の最も奥で穴に接しているため、嵌め込み直交方向へは、穴の移動が規制される。結果、樹脂部材は、長手方向（嵌め込み直交方向）への熱膨張による伸びが吸収できなくなる。   Depending on the molding state and mounting state of the resin member, the shaft portion of the clip may come into contact with the hole at the innermost end in the fitting direction. When the resin member is long in the direction orthogonal to the fitting direction (the fitting orthogonal direction), the resin member tends to extend in the longitudinal direction due to thermal expansion. However, since the shaft portion is in contact with the hole at the back of the fitting direction, the movement of the hole is restricted in the fitting orthogonal direction. As a result, the resin member cannot absorb the elongation due to thermal expansion in the longitudinal direction (direction perpendicular to the fitting direction).

複数の取付部４０は、樹脂部材３０の長手方向に沿って離間して配置されている。複数の開口部４１は、取付部４０の取付方向及び樹脂部材３０の長手方向に対して直交する方向に向いており複数の固定部材５０に掛け止められる位置に配置されている。樹脂部材３０は、車体後方から固定部材５０に向けて移動させるだけで、複数の取付部４０が、複数の固定部材５０に掛け止められる。樹脂部材３０は、車体２０に取り付けられた状態において、車体前後方向及び上下方向への移動が規制されている。   The plurality of attachment portions 40 are arranged apart from each other along the longitudinal direction of the resin member 30. The plurality of openings 41 are disposed in positions that are oriented in the direction orthogonal to the mounting direction of the mounting portion 40 and the longitudinal direction of the resin member 30 and are latched by the plurality of fixing members 50. By simply moving the resin member 30 from the rear of the vehicle body toward the fixing member 50, the plurality of attachment portions 40 are latched on the plurality of fixing members 50. When the resin member 30 is attached to the vehicle body 20, movement in the vehicle longitudinal direction and the vertical direction is restricted.

また、樹脂部材３０は、車幅方向に長尺の部材であるため、熱膨張により車幅方向に伸びる。熱膨張による樹脂部材３０の伸びは、金属製の車体２０の伸びよりも大きい。このため、樹脂部材３０を車体２０に取り付けるには、樹脂部材３０の車幅方向への伸びを許容できる構造が必要である。以下、樹脂部材取付構造の詳細について説明する。   Moreover, since the resin member 30 is a long member in the vehicle width direction, it extends in the vehicle width direction due to thermal expansion. The elongation of the resin member 30 due to thermal expansion is larger than the elongation of the metal vehicle body 20. For this reason, in order to attach the resin member 30 to the vehicle body 20, a structure capable of allowing the resin member 30 to extend in the vehicle width direction is required. Details of the resin member mounting structure will be described below.

図４及び図５に示されるように、固定部材５０は、車体２０のフランジ部２３の下方から貫通穴２５に通されるとともに係止される車体側固定部５１と、この車体側固定部５１の下部に設けられるとともにフランジ部２３の下側に重ねられる平板状の基部５２と、この基部５２と、この基部５２からフランジ部２３とは反対側へ延びる第１腕部５３と、この第１腕部５３の先端から基部５２に沿って車体方向に延びる第２腕部５４とを有する。   As shown in FIGS. 4 and 5, the fixing member 50 is passed through the through hole 25 from below the flange portion 23 of the vehicle body 20 and is locked, and the vehicle body side fixing portion 51. A flat plate-like base 52 provided on the lower side of the flange portion 23 and superimposed on the lower side of the flange portion 23, the base portion 52, a first arm portion 53 extending from the base portion 52 to the opposite side of the flange portion 23, and the first A second arm portion 54 extending in the vehicle body direction along the base portion 52 from the distal end of the arm portion 53.

基部５２と、第１腕部５３と、第２腕部５４とは、樹脂部材３０の長手方向から見て略Ｕ字状に形成されている。また、固定部材５０は、第２腕部５４の先端に一体的に形成されるとともに、基部５２に対向している係止爪部６１を有する。係止爪部６１は、取付部４０の開口部４１に当接する平面状の係止面６２と、係止面６２の反対側に形成され係止爪部６１の頂点から先端に向けて傾斜する爪部側傾斜面６３と、係止面６２の基端側に凹んだ凹部６４とを有する。凹部６４を形成することで、係止面６２を基端側に広く形成することができる。   The base 52, the first arm 53, and the second arm 54 are formed in a substantially U shape when viewed from the longitudinal direction of the resin member 30. The fixing member 50 has a locking claw portion 61 that is formed integrally with the distal end of the second arm portion 54 and faces the base portion 52. The locking claw portion 61 is formed on the opposite side of the locking surface 62 with a flat locking surface 62 that contacts the opening 41 of the mounting portion 40, and is inclined from the apex of the locking claw portion 61 toward the tip. It has a claw portion-side inclined surface 63 and a concave portion 64 that is recessed on the proximal end side of the locking surface 62. By forming the recess 64, the locking surface 62 can be widely formed on the base end side.

基部５２の縁５５には、この縁５５から周囲へ延びた弾性を有するカバー５６が一体に形成され、基部５２がフランジ部２３に取り付けられた状態で、カバー５６の先端がフランジ部２３当接している。このため、基部５２の周りは、カバー５６によって覆われている。カバー５６は、基部５２の縁５５から先端に向かって傾斜するカバー側傾斜面５７を有する。   A cover 56 having elasticity extending from the edge 55 to the periphery is integrally formed on the edge 55 of the base portion 52, and the front end of the cover 56 contacts the flange portion 23 in a state where the base portion 52 is attached to the flange portion 23. ing. For this reason, the periphery of the base 52 is covered with the cover 56. The cover 56 has a cover-side inclined surface 57 that is inclined from the edge 55 of the base portion 52 toward the tip.

また、樹脂部材３０の取付部４０は、基部５２と第２腕部５４との間の溝５８に、挿入且つ基部５２に当接可能な挿入部４２を有する。この挿入部４２に開口部４１が形成されており、開口部４１は、取付部３０の取付方向及び樹脂部材３０の長手方向に直交する方向に向いている。開口部４１の内面のなかの、樹脂部材３０の長手方向に沿った取付方向側の端面は、係止爪部６１の係止面６２を係止するための、取付方向と略直交し且つ平面状の係止端面４３が形成されている。   The mounting portion 40 of the resin member 30 has an insertion portion 42 that can be inserted into and abutted against the base portion 52 in a groove 58 between the base portion 52 and the second arm portion 54. An opening 41 is formed in the insertion portion 42, and the opening 41 faces in a direction orthogonal to the mounting direction of the mounting portion 30 and the longitudinal direction of the resin member 30. The end surface on the mounting direction side along the longitudinal direction of the resin member 30 in the inner surface of the opening 41 is substantially perpendicular to the mounting direction and is a plane for locking the locking surface 62 of the locking claw portion 61. A locking end surface 43 is formed.

挿入部４２は、基部５２に面した平板状に形成されており、挿入部４２のなかの第２腕部５４に対向する面は、先端に向かって薄肉となる傾斜面４４に形成されている。さらに、挿入部４２の先端には、基部５２に向かって滑らかに屈曲した屈曲部４５が形成されており、この屈曲部４５は、挿入された状態で基部５２に当接している。   The insertion portion 42 is formed in a flat plate shape facing the base portion 52, and the surface of the insertion portion 42 that faces the second arm portion 54 is formed as an inclined surface 44 that becomes thinner toward the tip. . Further, a bent portion 45 that is smoothly bent toward the base portion 52 is formed at the distal end of the insertion portion 42, and the bent portion 45 is in contact with the base portion 52 in the inserted state.

樹脂部材３０は、本体部３２に車体２０との間をシールするためのシール部材３３が設けられている。固定部材５０の車体側固定部５１には、爪５９が設けられており、この爪５９がフランジ部２３の貫通穴２５に係止されている。なお、固定部材５０を取付部４０に取り付ける際の挿入方向を取付方向とする。   The resin member 30 is provided with a seal member 33 for sealing between the body portion 32 and the vehicle body 20. A claw 59 is provided in the vehicle body side fixing portion 51 of the fixing member 50, and the claw 59 is engaged with the through hole 25 of the flange portion 23. In addition, let the insertion direction at the time of attaching the fixing member 50 to the attachment part 40 be an attachment direction.

図６〜図８に示されるように、取付部４０は、挿入部４２先端の車幅方向全体にわたって屈曲部４４が形成されているので、リブの役割を果たし、取付部４０の剛性を向上させることができる。このため、取付部４０の先端側が変形し難くなり、取付部４０を固定部材５０に強固に係止することができる。   As shown in FIGS. 6 to 8, the attachment portion 40 is formed with a bent portion 44 over the entire vehicle width direction at the distal end of the insertion portion 42, and thus serves as a rib to improve the rigidity of the attachment portion 40. be able to. For this reason, the distal end side of the attachment portion 40 is hardly deformed, and the attachment portion 40 can be firmly locked to the fixing member 50.

また、挿入部４０の両縁４６には、一対のリブ４７が設けられている。このため、挿入部４２の長手方向の剛性を向上させることができ、樹脂部材３０を取り付けた後も、挿入部４２が撓み難くなり、樹脂部材３０の好適な取付位置を維持することができる。   A pair of ribs 47 are provided on both edges 46 of the insertion portion 40. For this reason, the rigidity of the longitudinal direction of the insertion part 42 can be improved, and even after attaching the resin member 30, the insertion part 42 becomes difficult to bend and the suitable attachment position of the resin member 30 can be maintained.

図７〜図９に示されるように、固定部材５０は、第１腕部５３の先端から基部５２に沿って第２腕部５４の両側に延びる一対の第３腕部６５，６５を有している。一対の第３腕部６５，６５は、第２腕部５４に対して離間するとともに、基部５２に向かって弾性を有し、一対の第３腕部６５，６５の先端部６６，６６は、挿入部４２の当接部分４８，４８に当接している。   As shown in FIGS. 7 to 9, the fixing member 50 has a pair of third arm portions 65, 65 extending from the distal end of the first arm portion 53 to both sides of the second arm portion 54 along the base portion 52. ing. The pair of third arm portions 65, 65 are separated from the second arm portion 54 and have elasticity toward the base 52, and the tip portions 66, 66 of the pair of third arm portions 65, 65 are It abuts against the abutting portions 48 of the insertion portion 42.

樹脂部材３０の長手方向における、取付部４０の係止端面４３の幅はＬ１であり、一対のリブ４７，４７間の内幅はＬ２である。また、樹脂部材３０の長手方向における、固定部材５０の係止爪部６１の幅はＬ３であり、一対の第３腕部６５の外幅はＬ４である。車幅方向の位置決め基準となる取付部４０においては、Ｌ３＜Ｌ１であり、Ｌ４＜Ｌ２である。すなわち、取付部４０は、固定部材５０に対して車幅方向に移動可能である。（詳細後述。）   In the longitudinal direction of the resin member 30, the width of the locking end surface 43 of the mounting portion 40 is L1, and the inner width between the pair of ribs 47, 47 is L2. Further, the width of the locking claw portion 61 of the fixing member 50 in the longitudinal direction of the resin member 30 is L3, and the outer width of the pair of third arm portions 65 is L4. In the mounting portion 40 serving as a positioning reference in the vehicle width direction, L3 <L1 and L4 <L2. That is, the attachment portion 40 is movable in the vehicle width direction with respect to the fixed member 50. (Details will be described later.)

以上に述べた樹脂部材取付構造の作用を次ぎに説明する。
図５、図９に示されるように、樹脂部材３０の車体２０への取付は、予め車体２０に固定部材５０を固定し、車体後方から固定部材５０に向かって、樹脂部材３０の取付部４０を移動させる。 Next, the operation of the resin member mounting structure described above will be described.
As shown in FIGS. 5 and 9, the resin member 30 is attached to the vehicle body 20 in advance by fixing the fixing member 50 to the vehicle body 20 in advance, and from the rear of the vehicle body toward the fixing member 50. Move.

固定部材５０には、係止爪部６１の爪部側傾斜面６３と、カバー５６のカバー側傾斜面５７とが、車体後方に向かって広がるように形成されている。一方、取付部４０には、傾斜面４４によって挿入部４２が先細りに形成され、先端には屈曲部４５が形成されているため、挿入部４２の先端が細く且つ断面視で湾曲して形成されている。結果、挿入部４２を、固定部５０の溝５８に容易に挿入することができる。   The fixing member 50 is formed with a claw portion-side inclined surface 63 of the locking claw portion 61 and a cover-side inclined surface 57 of the cover 56 so as to spread toward the rear of the vehicle body. On the other hand, since the insertion portion 42 is tapered by the inclined surface 44 and the bending portion 45 is formed at the tip of the attachment portion 40, the tip of the insertion portion 42 is thin and curved in a sectional view. ing. As a result, the insertion portion 42 can be easily inserted into the groove 58 of the fixing portion 50.

また、固定部材５９は、係止面６２の基端側に凹部６４が形成されているため、小さいスペースであっても、係止面６２の面積を広くすることができる。結果、取付部４０の開口部４１に形成された係止端面４３を受けやすくでき、強固に取付部４０を係止することができる。   Further, since the fixing member 59 has the concave portion 64 formed on the proximal end side of the locking surface 62, the area of the locking surface 62 can be widened even in a small space. As a result, the engagement end surface 43 formed in the opening 41 of the attachment portion 40 can be easily received, and the attachment portion 40 can be firmly engaged.

次に車幅方向における、位置決め基準の取付部と、樹脂部材の熱膨張による伸びを吸収する取付部とについて説明する。
図１０は位置決め基準の取付部を車体前方から見た図であり、図２及び図３に示した複数の固定部材５０と取付部４０のなかの、一組の固定部材５０と取付部４０は、一対の第３腕部６５，６５の外幅がＬ４であり、一対のリブ４７，４７間の内幅がＬ５であり、Ｌ４とＬ５が略同一に設定されている。このため、車幅方向において、固定部材５０に対して、取付部４０の移動が規制され、車幅方向の位置決めがなされる。 Next, a positioning reference mounting portion and a mounting portion that absorbs elongation due to thermal expansion of the resin member in the vehicle width direction will be described.
FIG. 10 is a view of the positioning reference mounting portion as viewed from the front of the vehicle body. Among the plurality of fixing members 50 and mounting portions 40 shown in FIG. 2 and FIG. The outer width of the pair of third arm portions 65, 65 is L4, the inner width between the pair of ribs 47, 47 is L5, and L4 and L5 are set substantially the same. For this reason, in the vehicle width direction, the movement of the attachment portion 40 is restricted with respect to the fixed member 50, and positioning in the vehicle width direction is performed.

一方、図１１は樹脂部材の熱膨張による伸びを吸収する取付部を車体前方から見た図であり、固定部材５０と取付部４０において、一対の第３腕部６５，６５の外幅がＬ４であり、一対のリブ４７，４７間の内幅がＬ２であり、Ｌ４＜Ｌ２に設定されている。このため、車幅方向において、固定部材５０に対して、取付部４０の移動が許容される。   On the other hand, FIG. 11 is a view of the attachment portion that absorbs elongation due to thermal expansion of the resin member as seen from the front of the vehicle body. In the fixing member 50 and the attachment portion 40, the outer width of the pair of third arm portions 65, 65 is L4. The inner width between the pair of ribs 47, 47 is L2, and L4 <L2. For this reason, the movement of the attachment portion 40 is allowed with respect to the fixing member 50 in the vehicle width direction.

また、図１０の固定部材５０と、図１１の固定部材５０とは、寸法が等しい共通の部材であり、固定部材を生産するための金型を共通にして、部品コストを抑えることができる。また、樹脂部材３０のおいては、複数の取付部４０のなかの１箇所だけ寸法を変更するだけですみ、別途金型を用意する必要がなく、全体としても製造コストを低減できる。なお、位置決め基準とする取付部４０は、任意の位置でよいが、樹脂部材３０の車幅方向中央に近い取付部４０であることが好ましい。このようにすることで、樹脂部材３０の熱膨張による伸びを、基準位置の左右に振り分けることができる。   Further, the fixing member 50 in FIG. 10 and the fixing member 50 in FIG. 11 are common members having the same dimensions, and a die for producing the fixing member can be used in common to reduce the component cost. Further, in the resin member 30, it is only necessary to change the dimension of one of the plurality of mounting portions 40, and it is not necessary to prepare a separate mold, and the manufacturing cost can be reduced as a whole. In addition, although the attachment part 40 used as a positioning reference | standard may be arbitrary positions, it is preferable that it is the attachment part 40 near the vehicle width direction center of the resin member 30. FIG. By doing in this way, the elongation by the thermal expansion of the resin member 30 can be distributed to the right and left of the reference position.

次に樹脂部材の熱膨張による伸びを吸収する取付部の作用を説明する。
図１２（ａ）は熱膨張を受ける前の状態を示す図であり、車幅方向において、係止爪部６１と開口部４１との間には隙間がある。また、車幅方向において、一対の第３腕部６５，６５と一対のリブ４７，４７との間にも隙間がある。樹脂部材３０が熱膨張により車幅方向に伸びると、係止面６２が係止端面４３に当接した状態を維持し、取付部４０は矢印ａのように移動する。 Next, the effect | action of the attachment part which absorbs the elongation by the thermal expansion of a resin member is demonstrated.
FIG. 12A is a diagram showing a state before thermal expansion, and there is a gap between the locking claw 61 and the opening 41 in the vehicle width direction. Further, there is a gap between the pair of third arm portions 65 and 65 and the pair of ribs 47 and 47 in the vehicle width direction. When the resin member 30 extends in the vehicle width direction due to thermal expansion, the state in which the locking surface 62 is in contact with the locking end surface 43 is maintained, and the mounting portion 40 moves as indicated by an arrow a.

図１２（ｂ）は熱膨張後の状態を示す図であり、車幅方向右側の第３腕部６５の側面は、リブ４７に当接している。また、係止爪部６１の係止面６２は、取付部５０の係止端面４３に当接した状態である。このように、取付部５０は、車体前後方向においては移動ぜずに、車幅方向にのみ移動することができる。すなわち、図１において、車体２０に対して、樹脂部材３０の前後方向の位置は保持し、樹脂部材３０の車幅方向の伸びのみを吸収することができる。なお、樹脂部材３０の熱膨張による伸びが小さい場合は、第３腕部６５にリブ４７が当接しない。   FIG. 12B is a diagram illustrating a state after thermal expansion, and the side surface of the third arm portion 65 on the right side in the vehicle width direction is in contact with the rib 47. Further, the locking surface 62 of the locking claw portion 61 is in contact with the locking end surface 43 of the mounting portion 50. As described above, the attachment portion 50 can move only in the vehicle width direction without moving in the longitudinal direction of the vehicle body. That is, in FIG. 1, the position of the resin member 30 in the front-rear direction can be maintained with respect to the vehicle body 20, and only the elongation of the resin member 30 in the vehicle width direction can be absorbed. When the elongation due to thermal expansion of the resin member 30 is small, the rib 47 does not contact the third arm portion 65.

以上に述べた締結構造をまとめて以下に記載する。
図１２に示されるように、開口部４１の内面のなかの、取付方向側の端面は、係止爪部６１の係止面６２を係止するための、取付方向と略直交し且つ平面状の係止端面４３を構成し、係止爪部６１の係止面６２は、平面状に形成されており、係止端面４３に係止面６２が当接しているので、樹脂部材３０の長手方向に対して直交する方向へは、樹脂部材３０の移動を規制して車体から離れないように係止できる。また、樹脂部材３０の長手方向において、平面状の係止端面４３の幅が、平面状の係止爪部６１の幅よりも大きく設定されているので、樹脂部材３０の長手方向へは、樹脂部材３０の熱膨張による伸びを吸収できる。 The fastening structure described above is summarized and described below.
As shown in FIG. 12, the end surface on the attachment direction side of the inner surface of the opening 41 is substantially perpendicular to the attachment direction for engaging the engagement surface 62 of the engagement claw portion 61 and is planar. The locking end surface 43 of the locking claw 61 is formed in a flat shape, and the locking surface 62 is in contact with the locking end surface 43, so that the length of the resin member 30 is long. In a direction perpendicular to the direction, the movement of the resin member 30 can be restricted so as not to leave the vehicle body. Further, in the longitudinal direction of the resin member 30, the width of the planar locking end surface 43 is set to be larger than the width of the planar locking claw portion 61. The elongation due to the thermal expansion of the member 30 can be absorbed.

図５に示されるように、固定部材５０は、係止爪部６１の係止面６２の基端側に凹んだ凹部６４を有しているので、係止面６２を広く形成することができる。平面状の係止面６２と平面上の係止端面４３とを広い面積で当接させることができ、係止を強固にして、固定部材５０から樹脂部材３０が外れることを防止できる。   As shown in FIG. 5, the fixing member 50 has a recessed portion 64 that is recessed on the proximal end side of the locking surface 62 of the locking claw portion 61, so that the locking surface 62 can be formed widely. . The planar locking surface 62 and the planar locking end surface 43 can be brought into contact with each other over a wide area, and the locking can be strengthened to prevent the resin member 30 from being detached from the fixing member 50.

図５に示されるように、固定部材５０と樹脂部材３０は、係止爪部６１が係止端面４３に当接するとともに、基部５２が挿入部４２に当接しているので、挿入部４２は、基部５２及び第２腕部５４に向かう方向へも移動が規制される。結果、挿入部４２から見て基部５２及び第２腕部５４に向かう方向への、樹脂部材３０の移動を規制し、安定して固定することができる。   As shown in FIG. 5, the fixing member 50 and the resin member 30 have the locking claw 61 abutting on the locking end surface 43 and the base 52 abutting on the insertion portion 42. Movement is also restricted in the direction toward the base 52 and the second arm 54. As a result, the movement of the resin member 30 in the direction toward the base 52 and the second arm portion 54 when viewed from the insertion portion 42 can be restricted and stably fixed.

図５及び図９に示されるように、挿入部４２を、基部５２と第２腕部５４との間に挿入する際、傾斜面４４と屈曲部４５によってガイドでき、容易に挿入できる。   As shown in FIGS. 5 and 9, when the insertion portion 42 is inserted between the base portion 52 and the second arm portion 54, it can be guided by the inclined surface 44 and the bent portion 45 and can be easily inserted.

図５に示されるように、屈曲部４５は、挿入された状態で基部５２に当接しているので、屈曲部４５の一部分によって当接と取付性の向上を達成できる。   As shown in FIG. 5, since the bent portion 45 is in contact with the base portion 52 in the inserted state, it is possible to achieve improvement in contact and attachment by a part of the bent portion 45.

図５に示されるように、基部５２が車体２０に取り付けられた状態で、カバー５６の先端が車体２０に当接することで、基部５２の周りをカバー５６によって覆うように構成されているので、基部５２が車体２０に当接する部分を覆い隠すことができる。   As shown in FIG. 5, the base 52 is attached to the vehicle body 20, and the front end of the cover 56 abuts the vehicle body 20, so that the base 52 is covered with the cover 56. A portion where the base 52 contacts the vehicle body 20 can be covered.

図５に示されるように、カバー５６は、基部５２の縁から先端に向かって傾斜している。挿入部４２を、基部５２と第２腕部５４との間に挿入する際、カバー５６の傾斜によって挿入部４２をガイドでき、容易に挿入できる。   As shown in FIG. 5, the cover 56 is inclined from the edge of the base 52 toward the tip. When inserting the insertion part 42 between the base part 52 and the 2nd arm part 54, the insertion part 42 can be guided by the inclination of the cover 56, and it can insert easily.

図５に示されるように、固定部材５０と取付部４０とは、樹脂部材３０の長手方向に複数組設けられ、そのうちの一組は、一対のリブ４７，４７間の内幅に対して、一対の第３腕部６５，６５の外幅を略同一に設定されているので、取付部４０のリブ４７，４７間の内幅を変更するだけで、固定部材５０は共通のまま、基準点となる取付部４０と、熱膨張による伸びを許容する取付部４０とを有することができる。   As shown in FIG. 5, a plurality of sets of the fixing member 50 and the attachment portion 40 are provided in the longitudinal direction of the resin member 30, and one set of the fixing member 50 and the mounting portion 40 is in relation to the inner width between the pair of ribs 47, 47. Since the outer widths of the pair of third arm portions 65, 65 are set to be substantially the same, only the inner width between the ribs 47, 47 of the mounting portion 40 is changed, and the fixing member 50 remains common and the reference point And a mounting portion 40 that allows elongation due to thermal expansion.

尚、実施例では、樹脂部材３０を、車体２０のライセンスプレート１２上方を装飾するガーニッシュとしたが、これに限定されず、車体２０の左右や前面に取り付ける樹脂部材や、樹脂部材を車体に対して傾斜して取り付けたり、樹脂部材の長手方向が上下方向になるように取り付ける場合であっても差し支えない。   In the embodiment, the resin member 30 is a garnish that decorates the upper part of the license plate 12 of the vehicle body 20, but is not limited to this, and the resin member attached to the left and right or the front surface of the vehicle body 20 or the resin member is attached to the vehicle body. Even if it is attached so that the longitudinal direction of the resin member is in the vertical direction, there is no problem.

また、実施例では、車体２０に固定部材５０を設け、樹脂部材３０に取付部４０を設けたが、これに限定されず、樹脂部材３０に固定部材５０を設け、車体２０に取付部４０を設けても差し支えない。   In the embodiment, the fixing member 50 is provided on the vehicle body 20 and the mounting portion 40 is provided on the resin member 30. However, the present invention is not limited to this, and the fixing member 50 is provided on the resin member 30 and the mounting portion 40 is provided on the vehicle body 20. It can be provided.
