Description
本発明は、車両に装着されたルーフモールのキャリア取付用の開口部を塞ぐキャップの取付構造に関する。 The present invention relates to a cap mounting structure that closes an opening for mounting a carrier on a roof molding attached to a vehicle.
車両に装着されたルーフモールに、ルーフラック、キャリアバー等のキャリア装置を取り付けるための開口部を有し、この開口部をキャリア装置の未取付時に着脱自在のキャップで塞ぐ構造として、例えば特許文献１が挙げられる。
特許文献１のルーフモールは、開口部に幅方向両側から内側に突出した一対の係止片とルーフモールの長手方向に沿った開口部の外側に係止孔を有し、この開口部を上面側から塞ぐ蓋部を有するキャップが、蓋部に裏面の幅方向両側から外側に突出した略Ｌ字形状のスライド爪と長手方向外側に向けて設けた係止爪を有する。
このような構造は、キャップをルーフモールの係止孔に向けてスライドさせると、キャップのスライド爪、係止爪がそれぞれルーフモールの係止片、係止孔に係止し、キャップを取り外す際には、キャップをルーフモールの係止孔とは反対側にスライドさせる操作と、スライド爪側を上に持ち上げる操作の２ステップ動作を行わないと取り外せないため、キャップがルーフモールから不本意なスライド動作により外れるのを防止できる。
しかし、キャップに設けたスライド爪が剛性を有する場合、例えばルーフモールが金属製の芯材と樹脂材で複合成形されてあり、樹脂材の厚みがバラツキにより厚くなるとスライド爪の開閉力は高くなり、逆に薄くなるとキャップの裏面とルーフモールの上面の間にスキが生じやすくなり、見栄えが悪くなる、風切り音が大きくなることなどが懸念される。
Patent document 1, for example, describes a structure in which a roof molding attached to a vehicle has an opening for attaching a carrier device such as a roof rack or carrier bar, and this opening is covered with a removable cap when the carrier device is not attached.
The roof molding of Patent Document 1 has a pair of locking pieces that protrude inward from both sides of the width of the opening and a locking hole on the outside of the opening along the longitudinal direction of the roof molding, and a cap with a lid that covers the opening from the top side has approximately L-shaped sliding claws that protrude outward from both sides of the width of the back surface of the lid and locking claws that are provided facing outward in the longitudinal direction.
With this structure, when the cap is slid toward the locking hole in the roof molding, the sliding claw and locking claw of the cap lock into the locking piece and locking hole in the roof molding, respectively.To remove the cap, a two-step operation is required: sliding the cap in the opposite direction from the locking hole in the roof molding, and lifting the sliding claw side up.This prevents the cap from coming off the roof molding due to an unintended sliding movement.
However, if the sliding claws on the cap are rigid, for example, if the roof molding is compositely molded from a metal core and a resin material, and the thickness of the resin material varies, the opening and closing force of the sliding claws will increase if the material becomes thicker, and conversely, if the material becomes thinner, gaps will be more likely to occur between the back surface of the cap and the top surface of the roof molding, which will result in a poor appearance and increased wind noise, raising concerns.
本発明は、ロバスト性の高いルーフモールのキャップ取付構造の提供を目的とする。 The present invention aims to provide a highly robust roof molding cap mounting structure.
本発明に係るルーフモールのキャップ取付構造は、車両に装着されたルーフモールのキャリア取付用の開口部を塞ぐキャップの取付構造であって、前記開口部は内側に対向して突出した一対のリブ部を複数組有し、前記キャップは前記ルーフモールの開口部を上面側から塞ぐ蓋部と、前記蓋部の裏面から下側に突出した支持部と、前記支持部の幅方向両側から外側に突出して前記ルーフモールの一対のリブ部の下面に弾性当接する一対の保持片を有し、前記ルーフモールのリブ部が前記キャップの蓋部と保持片の間に前後方向からスライド挿入されるものであることを特徴とする。 The roof molding cap mounting structure of the present invention is a cap mounting structure for closing an opening for mounting a carrier in a roof molding attached to a vehicle, wherein the opening has multiple pairs of ribs protruding inward in opposing directions, and the cap has a lid portion that closes the opening of the roof molding from above, a support portion that protrudes downward from the back surface of the lid portion, and a pair of retaining pieces that protrude outward from both widthwise sides of the support portion and elastically abut against the undersides of the pair of ribs of the roof molding, and the ribs of the roof molding are slidably inserted between the lid portion and the retaining pieces of the cap from the front-to-rear direction.
ここで、幅方向とはルーフモールを車両のルーフの前後方向に沿って装着した場合の車幅方向を、前後方向とは車両の前後方向を、外側とはルーフモールの開口部に対しての相対的な外側をいう。
本発明は、ルーフモール（例えば樹脂材の厚み）にバラツキがあっても、ロバスト性の高い、すなわちバラツキの影響を受けにくく、安定してルーフモールの開口部にキャップを取り付けられるように、キャップの蓋部と保持片の間でルーフモールのリブ部を弾性保持してバラツキを吸収するとともに、保持片の反発力によってキャップの上下方向のガタ付きを解消する。
Here, the width direction refers to the vehicle width direction when the roof molding is installed along the fore-and-aft direction of the vehicle roof, the fore-and-aft direction refers to the front-and-aft direction of the vehicle, and the outside refers to the outside relative to the opening of the roof molding.
The present invention provides a highly robust cap, i.e., one that is less susceptible to the effects of variations, even if there are variations in the roof molding (e.g., the thickness of the resin material), allowing the cap to be stably attached to the opening of the roof molding.The rib portion of the roof molding is elastically held between the lid portion of the cap and the retaining piece to absorb variations, and the repulsive force of the retaining piece eliminates any rattle of the cap in the vertical direction.
本発明において、前記キャップは蓋部の裏面と保持片との間にスライド凹部が形成されており、前記スライド凹部の底部と前記ルーフモールのリブ部の先端部との間に所定の隙間部を有しているものであってもよい。
このようにスライド凹部の底部となるキャップの支持部と、ルーフモールのリブ部の先端部との間に所定の隙間部を有していることで、支持部に連結した保持片が上下方向に撓みやすい。
また、この隙間部を調整することで、弾み力の調整が可能になる。
例えば、前記キャップの保持片は前記蓋部の裏面に対して根元部よりも先頭部の間隔の方が広く設定してあり、前記ルーフモールのリブ部の先端部の幅方向食い込み量が所定の範囲になっていてもよい。
キャップの保持片と蓋部の裏面との上下方向の間隔が、ルーフモールのリブ部側で広いことで、保持片は根元部側に隙間部を有して先頭部側がリブ部に弾性当接しやすく、スライド凹部にリブ部が食い込むことで、従来のスキが生じにくい。
In the present invention, the cap may have a slide recess formed between the back surface of the lid portion and the retaining piece, and may have a predetermined gap between the bottom of the slide recess and the tip of the rib portion of the roof molding.
In this way, by providing a predetermined gap between the support portion of the cap, which forms the bottom of the slide recess, and the tip of the rib portion of the roof molding, the retaining piece connected to the support portion is easily bent in the vertical direction.
Moreover, by adjusting this gap, it is possible to adjust the elasticity.
For example, the retaining piece of the cap may be set so that the distance from the back surface of the lid portion is wider at the tip than at the base, and the widthwise penetration amount of the tip of the rib portion of the roof molding may be within a predetermined range.
The vertical distance between the retaining piece of the cap and the back surface of the lid is wider on the rib side of the roof molding, so the retaining piece has a gap on the base side and the leading end side easily comes into elastic contact with the rib part, and the rib part bites into the slide recess, making it less likely that gaps will occur as in the past.
本発明において、前記ルーフモールはさらに前記開口部から長手方向に所定距離離間して設けた係止孔を有し、前記キャップはさらに前記蓋部の裏面に長手方向外側に向けて突出した係止爪を有し、前記ルーフモールの係止孔に前記キャップの係止爪が係止するものであってもよい。
また、前記キャップの保持片は前記蓋部の裏面から遠ざかるように前記係止爪側に突出した傾斜部を有するものであってもよい。
このような傾斜部により、キャップの蓋部と保持片の間にルーフモールのリブ部を誘い込みやすい。
In the present invention, the roof molding may further have a locking hole provided at a predetermined distance longitudinally from the opening, and the cap may further have a locking claw protruding longitudinally outward on the back surface of the lid portion, so that the locking claw of the cap engages with the locking hole of the roof molding.
The holding piece of the cap may have an inclined portion that projects toward the locking claw so as to move away from the rear surface of the lid portion.
Such an inclined portion makes it easier to guide the rib portion of the roof molding between the lid portion of the cap and the retaining piece.
本発明において、前記キャップは一対の保持片の近傍に前記ルーフモールの一対のリブ部の先端部に当接する幅位置決め部及び／又は仮位置決め部を有してもよい。
ルーフモールの開口部にキャップを仮付け（保持片を開口部に挿入）する際に仮位置決め部が、開口部にキャップを取り付け（保持片がリブ部に弾性当接）した状態で幅位置決め部が、ルーフモールの一対のリブ部の先端部に当接することで、ルーフモールに対するキャップの幅方向位置が安定する。
In the present invention, the cap may have width positioning portions and/or temporary positioning portions in the vicinity of the pair of holding pieces that come into contact with the tip ends of the pair of rib portions of the roof molding.
When temporarily attaching the cap to the opening of the roof molding (inserting the retaining piece into the opening), the temporary positioning portion abuts the tip ends of a pair of rib portions of the roof molding while the cap is attached to the opening (the retaining piece elastically abuts the rib portion), thereby stabilizing the widthwise position of the cap relative to the roof molding.
本発明によれば、ルーフモールの厚み等にバラツキがあってもキャップの蓋部と保持片の間でルーフモールのリブ部を弾性保持してバラツキを吸収するため、ロバスト性高くルーフモールの開口部にキャップを取り付けられる。
また、簡単な操作で確実にキャップを取り付けられるとともに、キャップがルーフモールから不本意に外れるのを防止できる。
According to the present invention, even if there is variation in the thickness of the roof molding, the rib portion of the roof molding is elastically held between the lid portion of the cap and the retaining piece, thereby absorbing the variation, allowing the cap to be attached to the opening of the roof molding with high robustness.
Furthermore, the cap can be securely attached with a simple operation, and the cap can be prevented from being accidentally removed from the roof molding.
本発明に係るルーフモールのキャップ取付構造例を、以下、図に基づいて説明する。
図１はキャップ１０を裏面側から、図２は表面側から見た状態であり、それぞれ（ａ）にルーフモール２０から取り外した状態、（ｂ）に取り付けた状態を示す。
本明細書において、ルーフモールを車両のルーフの前後方向に沿って装着した場合の車幅方向を幅方向といい、車両の前後方向、すなわちルーフモールの長手方向を前後方向という。
また、外側とはルーフモールの開口部に対しての相対的な外側をいう。
An example of a roof molding cap mounting structure according to the present invention will be described below with reference to the drawings.
1 shows the cap 10 as viewed from the rear side, and FIG. 2 shows it as viewed from the front side, with (a) showing the cap removed from the roof molding 20 and (b) showing the cap attached thereto.
In this specification, the width direction of the vehicle when the roof molding is attached along the fore-and-aft direction of the vehicle roof is referred to as the width direction, and the fore-and-aft direction of the vehicle, i.e., the longitudinal direction of the roof molding, is referred to as the fore-and-aft direction.
Also, the outside refers to the outside relative to the opening of the roof molding.
ルーフモール２０は、車両のルーフの前後方向に沿って装着される。
例えば図４に示すように、金属製の芯材２０ａと樹脂材２０ｂとで複合成形されている。
図１に示すように、ルーフモール２０はキャリア装置をルーフに取り付けるための開口部２１と、この開口部から長手方向に所定の距離を離間して設けた係止孔２４を有する。
開口部２１は、ルーフモールの長手方向に沿って細長の略矩形形状に形成してあり、開口面に沿って幅方向両側から内側に対向して突出された一対のリブ部を複数組有する。
本実施例は、開口部の一端２１ｂから長手方向に所定の距離を隔てた位置に一対の第１リブ部２２，２２と、係止孔２４側の他端２１ｃのコーナー部から内側に突出させた一対の第２リブ部２３，２３のほかに、第１及び第２リブ部の間に所定の間隔で一対の第３リブ部２６，２６と一対の第４リブ部２７，２７を有する例である。
なお、一対のリブ部を複数組有するとは、少なくとも第１及び第２リブ部を有するものであればよく、第１及び第２リブ部の間に有する一対のリブ部の数や間隔に特に制限はない。
例えば一対の第１リブ部の先端部２２ａ、２２ａが、幅方向に隙間Ｄを有して対向するように、各一対のリブ部の先端部間に隙間を有する。
開口部の一端２１ｂと第１リブ部２２との間は、後述するキャップの第１保持部１２（及び第１幅位置決め部１５ａ、１５ｂ）が上下方向に移動可能な幅寸法の逃げ開口部２１ａとなっている。
また、開口部の他端２１ｃから外側（図１における右側）に向けて所定の距離を隔てた位置に係止孔２４を有することで、他端２１ｃと係止孔２４の間はルーフモールの本体部を残したつなぎ部２５となっている。
The roof molding 20 is attached along the front-to-rear direction of the roof of the vehicle.
For example, as shown in FIG. 4, it is composite-molded with a metal core material 20a and a resin material 20b.
As shown in FIG. 1, the roof molding 20 has an opening 21 for attaching the carrier device to the roof, and a locking hole 24 provided at a predetermined distance in the longitudinal direction from the opening.
The opening 21 is formed in a generally rectangular shape that is elongated along the longitudinal direction of the roof molding, and has a plurality of pairs of rib portions that protrude inward from both sides in the width direction along the opening surface, facing each other.
This embodiment is an example having a pair of first rib portions 22, 22 located a predetermined distance longitudinally from one end 21b of the opening, a pair of second rib portions 23, 23 protruding inward from the corner portion of the other end 21c on the engagement hole 24 side, as well as a pair of third rib portions 26, 26 and a pair of fourth rib portions 27, 27 at a predetermined interval between the first and second rib portions.
In addition, having multiple pairs of rib portions means having at least first and second rib portions, and there are no particular restrictions on the number or spacing of pairs of rib portions between the first and second rib portions.
For example, the tip ends 22a, 22a of a pair of first rib portions are opposed to each other with a gap D in the width direction, and a gap is provided between the tip ends of each pair of rib portions.
Between one end 21b of the opening and the first rib portion 22 is an escape opening 21a having a width dimension that allows the first holding portion 12 (and first width positioning portions 15a, 15b) of the cap described later to move in the vertical direction.
In addition, by providing a locking hole 24 at a position a predetermined distance away from the other end 21c of the opening toward the outside (to the right in Figure 1), a connecting portion 25 is formed between the other end 21c and the locking hole 24, leaving the main body of the roof molding.
キャップ１０は、ルーフモールの開口部２１を上面側から塞ぐ蓋部１１を有する。
蓋部１１の裏面には、ルーフモールの一対のリブ部を弾性保持する保持部を有する。
本実施例は、一対の第１リブ部２２，２２、一対の第２リブ部２３，２３、一対の第３リブ部２６，２６、一対の第４リブ部２７，２７をそれぞれ弾性保持する第１保持部１２、第２保持部１３、第３保持部１６、第４保持部１７を有し、各保持部の形状が類似する。
なお、第１及び第２リブ部をそれぞれ保持する第１及び第２保持部を有するものであれば、必ずしも第３リブ部、第４リブ部、・・・を保持する第３保持部、第４保持部、・・・を有する必要はない。
以下、対応する第１保持部と第１リブ部を例に説明するが、「第１」を「第２、第３、第４、・・・」と読替えることで、対応する他の保持部とリブ部についても説明できる。
The cap 10 has a lid portion 11 that closes the opening 21 of the roof molding from the upper side.
The rear surface of the cover 11 has a retaining portion that elastically retains a pair of rib portions of the roof molding.
This embodiment has a first retaining portion 12, a second retaining portion 13, a third retaining portion 16, and a fourth retaining portion 17 that elastically retain a pair of first rib portions 22, 22, a pair of second rib portions 23, 23, a pair of third rib portions 26, 26, and a pair of fourth rib portions 27, 27, respectively, and the shapes of each retaining portion are similar.
In addition, as long as it has first and second retaining portions that respectively hold the first and second rib portions, it does not necessarily have to have third retaining portions, fourth retaining portions, etc. that hold the third rib portion, fourth rib portion, etc.
The following explanation will be given using the corresponding first retaining portion and first rib portion as an example, but by replacing "first" with "second, third, fourth, ...", other corresponding retaining portions and rib portions can also be explained.
第１保持部１２は、蓋部１１の裏面の幅方向略中央から下側に突出した略コ字形状の第１支持部１２ａと、第１支持部１２ａの幅方向両側から外側に突出した弾性変形可能な一対の第１保持片１２ｂ、１２ｂを有する。
図１（ｂ）に示すようにキャップ１０をルーフモール２０の開口部２１に取り付けた状態では、キャップの一対の第１保持片１２ｂ，１２ｂが、ルーフモールの一対の第１リブ部２２，２２の下面に弾性当接する。
この弾性当接した状態のＡ－Ａ線（幅方向）断面を、図４に示す。
図４に示すように一対の第１保持片１２ｂ、１２ｂは、第１支持部１２ａからそれぞれ幅Ｌ１，Ｌ２を有して幅方向外側に延在している。
第１保持片１２ｂは、蓋部１１と第１支持部１２ａとで第１スライド凹部１２ｄを形成し、この第１スライド凹部は、支持部１２ａの幅方向外面が底部１２ｆとなって幅方向外側に開口している。
一対の第１リブ部２２、２２は、それぞれ第１スライド凹部１２ｄ、１２ｄを形成する蓋部１１の裏面と第１保持片１２ｂ、１２ｂに弾性狭持される。
この狭持された状態で、一対の第１スライド凹部の底部１２ｆ、１２ｆは、一対のリブ部の先端部２２ａ、２２ａとの間にそれぞれ隙間部Ｄ１、Ｄ２を有している。
ルーフモールの一対の第１リブ部２２，２２は、一対の第１スライド凹部１２ｄ、１２ｄに沿って前後方向から相対的に挿入スライドされるが、各第１保持片１２ｂは根元部（底部１２ｆ）側を起点として、先頭部１２ｅ側が下方向ｆ１、ｆ２に押し下げられるように撓み、蓋部１１の裏面との上下方向の間隔は根元部よりも先頭部１２ｅ側が広く設定されている。
これにより、一対の第１リブ部の先端部２２ａの幅方向食い込み量は、それぞれＬ１－Ｄ１，Ｌ２－Ｄ２となっている。
なお、隙間部Ｄ１＋Ｄ２は、一対の第１リブの先端部２２ａ、２２ａ間の隙間Ｄから、第１支持部１２ａの幅を差し引くことで求まる。
本実施例は、図１（ａ）に示すように第１保持片１２ｂが、蓋部１１の裏面から遠ざかるように後述する係止爪側１４に突出した第１傾斜部１２ｃを有する。
リブ部がスライド凹部に前後方向にスライド挿入される際に、傾斜部１２ｃと蓋部１１の上下方向の間隔が広いことで、傾斜部が誘い込み部として作用し、保持片１２ｂと蓋部１１の間にリブ部２２が挿入されやすくなる。
The first holding portion 12 has a first support portion 12a that is approximately C-shaped and protrudes downward from approximately the center of the width of the back surface of the lid portion 11, and a pair of elastically deformable first holding pieces 12b, 12b that protrude outward from both sides of the width of the first support portion 12a.
As shown in Figure 1(b), when the cap 10 is attached to the opening 21 of the roof molding 20, the pair of first retaining pieces 12b, 12b of the cap elastically abut against the underside of the pair of first rib portions 22, 22 of the roof molding.
A cross section taken along line AA (widthwise direction) in this elastically abutting state is shown in FIG.
As shown in FIG. 4, the pair of first holding pieces 12b, 12b extend outward in the width direction from the first support portion 12a with widths L1 , L2, respectively.
The first holding piece 12b forms a first slide recess 12d with the cover portion 11 and the first support portion 12a, and this first slide recess has a bottom 12f that is the widthwise outer surface of the support portion 12a and opens outward in the widthwise direction.
The pair of first rib portions 22, 22 are elastically held between the rear surface of the cover portion 11 forming the first slide recesses 12d, 12d and the first holding pieces 12b, 12b.
In this sandwiched state, the bottoms 12f, 12f of the pair of first slide recesses have gaps D1 , D2 respectively between them and the tip ends 22a, 22a of the pair of rib portions.
A pair of first rib portions 22, 22 of the roof molding are inserted and slid relatively from the front to back along a pair of first slide recesses 12d, 12d, but each first retaining piece 12b bends from the root portion (bottom portion 12f) side so that the front portion 12e side is pushed downward in directions f1 and f2 , and the vertical distance between the front portion 12e and the back surface of the cover portion 11 is set wider on the front portion 12e side than on the root portion.
As a result, the widthwise indentations of the tip ends 22a of the pair of first rib portions are L 1 -D 1 and L 2 -D 2 , respectively.
The gap D 1 +D 2 is calculated by subtracting the width of the first support portion 12 a from the gap D between the tip ends 22 a of the pair of first ribs.
In this embodiment, as shown in FIG. 1A, the first holding piece 12b has a first inclined portion 12c that protrudes toward a locking claw side 14 (described later) so as to move away from the rear surface of the cover portion 11.
When the rib portion is slid forward and backward into the slide recess, the wide vertical distance between the inclined portion 12c and the lid portion 11 causes the inclined portion to act as a guide portion, making it easier for the rib portion 22 to be inserted between the retaining piece 12b and the lid portion 11.
キャップ１０は図１に示すように、蓋部１１の裏面に長手方向外側に向けて突出する係止爪１４を有する。
係止爪１４は、第２保持部１３の長手方向外側に位置して弾性変形する断面略Ｌ字状で、キャップの裏面との間に挿入溝を形成してルーフモール本体部の厚みを入れ込む。
また、長手方向外側先端にルーフモールの係止孔２４に向けて突出する係止突部を有し、この係止突部がつなぎ部２５に係止する。
キャップ１０はさらに、保持部の近傍に一対のリブ部の先端部に当接する幅位置決め部及び／又は仮位置決め部を有する。
例えば、第１保持部１２の係止爪１４側の近傍に第１仮位置決め部１８ａ、１８ｂを有し、ルーフモールの逃げ開口部２１ａに第１保持部１２を挿入する際に、この第１仮位置決め部が一対の第１リブ部の先端部２２ａ、２２ａにそれぞれ当接する。
これにより、キャップの保持部とルーフモールのリブ部の幅方向位置が対応しやすくなる。
また、第１保持部１２の係止爪１４とは反対側の近傍に第１幅位置決め部１５ａ、１５ｂを有し、図１（ｂ）に示すようにキャップ１０をルーフモールの開口部２１に取り付けた状態で、第１幅位置決め部が一対の第１リブ部の先端部２２ａ、２２ａに当接する。
これにより、一対のスライド凹部の底部が、一対のリブ部の先端部との間に所定の隙間部を有していても、開口部に取り付けるキャップの幅方向位置が安定する。
なお、本実施例は、蓋部の裏面から下側に一対の仮位置決め部１８ａ、１８ｂ、一対の幅位置決め部１５ａ、１５ｂがそれぞれ突出する例であるが、第２保持部１３の係止爪側の近傍に設けた第２幅位置決め部１５ｃのように、幅方向に延在する１つの仮位置決め部、幅位置決め部が一対のリブ部の先端部に当接してもよい。
また、第４保持部１７の係止爪１４側の近傍にも第４仮位置決め部１８ｃ、１８ｄを設けた例を示すが、例えば第３保持部の近傍に第３仮位置決め部を有してもよい。
As shown in FIG. 1, the cap 10 has a locking claw 14 on the back surface of the lid portion 11 that protrudes outward in the longitudinal direction.
The locking claw 14 is located longitudinally outside the second holding portion 13 and has a generally L-shaped cross section that is elastically deformable, and forms an insertion groove between itself and the back surface of the cap to fit the thickness of the roof molding main body.
The outer longitudinal end of the roof molding has a locking projection that projects toward the locking hole 24 of the roof molding, and this locking projection is locked to the connecting portion 25 .
The cap 10 further has width positioning portions and/or temporary positioning portions in the vicinity of the holding portion that abut against the tip ends of the pair of ribs.
For example, the first retaining portion 12 has first temporary positioning portions 18a, 18b near the locking claw 14 side, and when the first retaining portion 12 is inserted into the escape opening 21a of the roof molding, these first temporary positioning portions abut against the tip ends 22a, 22a of a pair of first rib portions, respectively.
This makes it easier for the widthwise positions of the holding portion of the cap and the rib portion of the roof molding to correspond to each other.
In addition, the first retaining portion 12 has first width positioning portions 15a, 15b near the opposite side of the locking claw 14, and when the cap 10 is attached to the opening 21 of the roof molding as shown in Figure 1 (b), the first width positioning portions abut against the tip ends 22a, 22a of the pair of first rib portions.
This stabilizes the widthwise position of the cap attached to the opening, even if there is a predetermined gap between the bottoms of the pair of slide recesses and the tip ends of the pair of ribs.
In this embodiment, a pair of temporary positioning portions 18a, 18b and a pair of width positioning portions 15a, 15b each protrude downward from the back surface of the lid portion, but it is also possible for one temporary positioning portion or width positioning portion extending in the width direction to abut the tip portions of a pair of rib portions, such as the second width positioning portion 15c provided near the locking claw side of the second retaining portion 13.
In addition, although an example is shown in which the fourth temporary positioning portions 18c and 18d are provided near the locking claw 14 side of the fourth holding portion 17, the third temporary positioning portion may be provided near the third holding portion, for example.
キャップ１０をルーフモール２０の開口部２１に取り付ける手順を、図３、５に基づいて説明する。
キャップ１０を取り外した図３（ａ）の状態から（ｂ）に示すように、キャップ１０の第１保持部１２と第１幅位置決め部１５ａ、１５ｂをルーフモール２０の逃げ開口部２１ａに臨ませるようにして、キャップ１０の第２保持部１３、第３保持部１６、第４保持部１７及び係止爪１４を開口部２１に納める。
この際、第１仮位置決め部１８ａ、１８ｂが一対の第１リブ部の先端部２２ａ、２２ａに当たっている。
この状態から、キャップ１０を前後方向（図３における右方向）にスライドさせながら押し込むと、ルーフモール２０の各リブ部がキャップ１０の各スライド凹部に沿ってスライドし、弾性を有する係止爪１４がキャップの裏面から下方向に開くようにして、キャップがスライドする。
このとき、ルーフモールのリブ部の下側にキャップの傾斜部が入り込みながら、保持片がリブ部の下面に弾性当接する。
例として、図５（ａ）から（ｂ）に第１及び第３保持片の動きを示すが、第１及び第３リブ部２２、２６の下側に第１及び第３傾斜部１２ｃ、１６ｃが入り込んだ後、第１及び第３保持片１２ｂ、１６ｂが各リブ部の下面に当接する。
図３（ｃ）に、キャップ１０がルーフモール２０の開口部２１に取り付いた状態を示す。
キャップ１０の係止爪１４が弾性復帰し、係止爪の係止突部がルーフモールの係止孔２４内に突出係止し、ロックされている。
この状態では、第１幅位置決め部１５ａ、１５ｂが一対の第１リブ部２２，２２の先端部に、第２幅位置決め部１５ｃが一対の第２リブ部２３，２３の先端部に当たっている。
なお、キャップ１０をルーフモール２０から取り外す場合には、キャップ１０を図３における左方向にスライドしてキャップ１０の各保持片、係止爪１４をそれぞれルーフモール２０の各リブ部、係止孔２４から外した後、キャップ１０を持ち上げることができる。
The procedure for attaching the cap 10 to the opening 21 of the roof molding 20 will be described with reference to FIGS.
As shown in Figure 3(b) from the state in which the cap 10 is removed, the first retaining portion 12 and first width positioning portions 15a, 15b of the cap 10 are brought into contact with the escape opening 21a of the roof molding 20, and the second retaining portion 13, third retaining portion 16, fourth retaining portion 17 and locking claw 14 of the cap 10 are placed in the opening 21.
At this time, the first provisional positioning portions 18a, 18b abut against the tip ends 22a, 22a of the pair of first rib portions.
From this state, when the cap 10 is pushed in while sliding it in the front-to-rear direction (to the right in Figure 3), each rib portion of the roof molding 20 slides along each slide recess of the cap 10, and the elastic locking claws 14 open downward from the back surface of the cap, causing the cap to slide.
At this time, the inclined portion of the cap fits under the rib portion of the roof molding, and the holding piece elastically abuts against the lower surface of the rib portion.
As an example, Figures 5(a) and (b) show the movement of the first and third retaining pieces. After the first and third inclined portions 12c and 16c enter the underside of the first and third rib portions 22 and 26, the first and third retaining pieces 12b and 16b abut against the underside of each rib portion.
FIG. 3C shows the cap 10 attached to the opening 21 of the roof molding 20 .
The locking claw 14 of the cap 10 returns elastically, and the locking projection of the locking claw projects into the locking hole 24 of the roof molding and is locked.
In this state, the first width positioning portions 15a, 15b abut against the tip ends of the pair of first rib portions 22, 22, and the second width positioning portion 15c abuts against the tip ends of the pair of second rib portions 23, 23.
When removing the cap 10 from the roof molding 20, the cap 10 can be slid to the left in Figure 3 to release the retaining pieces and locking claws 14 of the cap 10 from the rib portions and locking holes 24 of the roof molding 20, and then the cap 10 can be lifted up.
例えば、従来の例として、キャップに設けたスライド爪が剛性を有する場合を、図６に示す。
図６に示すルーフモール２０１は、金属製の芯材２０１ａと樹脂材２０１ｂで複合成形されており、その開口部の幅方向両側から内側に突出した一対の第一係止片に、キャップ１０１の蓋部の裏面から突出した略Ｌ字形状の剛性を有する一対の第一スライド爪１２１、１２１が係止している。
例えばバラツキにより樹脂材２０１ｂの厚みが薄くなると、キャップ１０１の裏面とルーフモール２０１の上面の間にスキｄが生じやすくなる。
これに対して、本発明は図４に示すように、スライド凹部の底部１２ｆとリブ部の先端部２２ａとの間に所定の隙間を有しているので、保持片１２ｂが撓みやすく、ルーフモールの厚みのバラツキを吸収するのが容易である。
また、保持片の先頭部１２ｅ側が、蓋部１１の裏面からの離間距離が根元部側よりも広くなるように設定してあるので、リブ部がスライド凹部に食い込み、従来のスキｄが生じるのを防ぎやすい。
For example, as a conventional example, FIG. 6 shows a case where the slide claw provided on the cap has rigidity.
The roof molding 201 shown in Figure 6 is compositely molded from a metal core material 201a and a resin material 201b, and a pair of first locking pieces protruding inward from both sides of the width of the opening are engaged with a pair of rigid, approximately L-shaped first slide claws 121, 121 protruding from the back surface of the lid portion of the cap 101.
For example, if the thickness of the resin material 201b becomes thin due to variations, a gap d is likely to occur between the back surface of the cap 101 and the upper surface of the roof molding 201.
In contrast, as shown in Figure 4, the present invention has a predetermined gap between the bottom 12f of the slide recess and the tip 22a of the rib portion, so that the retaining piece 12b is easily bent and can easily absorb variations in the thickness of the roof molding.
In addition, the leading end 12e of the holding piece is set so that the distance from the rear surface of the lid 11 is wider than that from the base end, so that the rib portion bites into the slide recess, making it easier to prevent the conventional gap d from occurring.
