しかし、特許文献１では、固定部材の脚部の外側だけに溶着面部を形成し、該溶着面部に樹脂成形品との溶着箇所を設けるので、十分な溶着強度を得るためには、溶着面部を脚部の外側に広く配設する必要があり、省スペース化を実現できない。   However, in Patent Document 1, since the welding surface portion is formed only on the outer side of the leg portion of the fixing member, and the welding portion with the resin molded product is provided on the welding surface portion, in order to obtain sufficient welding strength, the welding surface portion is formed. It is necessary to dispose widely on the outside of the leg portion, and space saving cannot be realized.

本発明は、かかる点に鑑みてなされたものであり、その目的とするところは、省スペース化を実現することにある。   The present invention has been made in view of such points, and an object of the present invention is to realize space saving.

上記の目的を達成するため、本発明は、脚部の内側に溶着面部を形成し、脚部内側の溶着面部に溶着箇所を設けたことを特徴とする。   In order to achieve the above object, the present invention is characterized in that a welding surface portion is formed inside the leg portion, and a welding location is provided in the welding surface portion inside the leg portion.

具体的には、第１の発明は、固定部材が、開放部を有する脚部と、該脚部の一端部に形成された座面部とを有し、上記座面部には、係合部が形成されているか、又は上記係合部を有する係合部材が取り付けられ、上記固定部材が溶着された樹脂成形品を、上記係合部を取付体の被係合部に係合させることで上記取付体に取り付けた取付構造を対象とし、次のような解決手段を講じた。   Specifically, in the first invention, the fixing member has a leg portion having an open portion and a seat surface portion formed at one end portion of the leg portion, and the engaging portion has an engaging portion on the seat surface portion. An engagement member having an engagement portion formed or attached to the resin molded product to which the fixing member is welded is engaged with the engagement portion of the attachment body to engage the engagement portion. The following solutions were taken for the mounting structure attached to the mounting body.

すなわち、第１の発明は、上記樹脂成形品には、凸部が形成され、上記固定部材の脚部の他端部には、上記座面部との間に空間部を有するように溶着面部が一体に形成され、上記溶着面部における上記脚部に囲まれた領域には、挿通孔が貫通形成され、上記樹脂成形品の凸部は、上記固定部材の挿通孔に挿通されて該挿通孔周縁に溶着されていることを特徴とする。   That is, according to the first aspect of the present invention, a convex portion is formed on the resin molded product, and a welding surface portion is provided at the other end portion of the leg portion of the fixing member so as to have a space portion between the seat surface portion. An insertion hole is formed through the region of the welding surface portion surrounded by the leg portion, and the convex portion of the resin molded product is inserted through the insertion hole of the fixing member to form a peripheral edge of the insertion hole. It is characterized by being welded to.

第２の発明は、第１の発明に係る樹脂成形品の取付構造において、上記固定部材の溶着面部における上記脚部に囲まれた領域のうち、上記開放部に隣接する領域には、上記開放部側に向かって上記座面部から遠ざかるように当該座面部に対して傾斜する傾斜面部が形成され、上記挿通孔は、上記溶着面部の傾斜面部に形成されていることを特徴とする。   According to a second invention, in the resin molded product mounting structure according to the first invention, in the region surrounded by the leg portion in the welding surface portion of the fixing member, the region adjacent to the opening portion has the opening. An inclined surface portion that is inclined with respect to the seat surface portion is formed so as to move away from the seat surface portion toward the portion side, and the insertion hole is formed in the inclined surface portion of the welding surface portion.

第３の発明は、第１又は２の発明に係る樹脂成形品の取付構造において、上記固定部材の座面部には、上記係合部材が取り付けられていることを特徴とする。   According to a third aspect of the present invention, in the resin molded product mounting structure according to the first or second aspect of the present invention, the engaging member is mounted on the seat surface portion of the fixing member.

第４の発明は、第１〜３のいずれか１つの発明に係る樹脂成形品の取付構造において、上記樹脂成形品には、被係止部を有する被組付体が組み付けられ、上記固定部材の溶着面部は、上記脚部の他端部から張り出すように形成され、上記固定部材の溶着面部における上記脚部に外側から近接する箇所には、上記被組付体の被係止部に係止される係止部が形成されていることを特徴とする。   According to a fourth aspect of the present invention, in the resin molded product mounting structure according to any one of the first to third aspects of the present invention, an assembled body having a locked portion is assembled to the resin molded product, and the fixing member The welding surface portion is formed so as to project from the other end portion of the leg portion, and the portion of the welding surface portion of the fixing member that is close to the leg portion from the outside is connected to the locked portion of the assembly. A locking portion to be locked is formed.

第１の発明によれば、固定部材の脚部の内側に溶着箇所を設ける分、取付強度の確保に必要な脚部外側の溶着箇所を削減又は廃止できるので、脚部の外側に配設する溶着面部を縮小又は廃止し、省スペース化を実現できる。   According to the first aspect of the present invention, since the welded portion is provided inside the leg portion of the fixing member, the welded portion outside the leg portion necessary for securing the mounting strength can be reduced or eliminated. Space-saving can be realized by reducing or eliminating the weld surface.

また、挿通孔周りの溶着面部が脚部に囲まれて補強され、撓みにくくなっているので、溶着面部の撓みによる樹脂成形品のぐらつきを防止できる。   Moreover, since the welding surface part around the insertion hole is reinforced by being surrounded by the leg part and is difficult to bend, the wobbling of the resin molded product due to the bending of the welding surface part can be prevented.

第２の発明によれば、挿通孔の周縁部が、開放部に隣接し、かつ開放部側に向かって上記座面部から遠ざかるように傾斜しているので、溶着器を開放部から挿入して樹脂成形品の凸部先端に当接させる際、挿通孔の周縁部が溶着器に干渉しにくい。したがって、溶着作業が容易になる。   According to the second invention, the peripheral portion of the insertion hole is adjacent to the opening portion and is inclined so as to be away from the seat surface portion toward the opening portion side, so that the welder is inserted from the opening portion. When contacting the tip of the convex part of the resin molded product, the peripheral edge of the insertion hole is unlikely to interfere with the welder. Therefore, welding work is facilitated.

第３の発明によれば、係合部が破損したとき、係合部材を交換するだけで修理でき、固定部材を交換する必要がないので、修理費用を削減できる。   According to the third invention, when the engaging portion is broken, it can be repaired only by exchanging the engaging member, and it is not necessary to replace the fixing member, so that the repair cost can be reduced.

第４の発明によれば、固定部材の脚部の内側に溶着箇所を設ける分、取付強度の確保に必要な脚部外側の溶着箇所が減るので、脚部の外側に係止部の配設スペースを確保しやすい。   According to the fourth aspect of the present invention, since the welded portion on the outside of the leg portion necessary for securing the mounting strength is reduced by providing the welded portion on the inner side of the leg portion of the fixing member, the engagement portion is disposed on the outer side of the leg portion. Easy to secure space.

次に、車体３のＣピラー部にＣピラートリム１５が取り付けられた状態で、上記のように構成されたＤピラートリム１３を、固定部材２７を介して車体３のルーフサイドレール５及びＣピラートリム１５に取り付ける手順を説明する。まず、図７に示すように、Ｄピラートリム１３の縦リブ３１及び横リブ３３の先端面における第１溶着凸部３７形成箇所及び第２溶着凸部３９形成箇所を除く領域に、固定部材２７の溶着面部５３の裏面を当接させるとともに、Ｄピラートリム１３の第１溶着凸部３７を固定部材２７の第１挿通孔５５に挿通し、Ｄピラートリム１３の第２溶着凸部３９を固定部材２７の第２挿通孔５９に挿通する。この状態で、Ｄピラートリム１３の第１溶着凸部３７が固定部材２７の第１突出板部５７よりも突出している。そして、この状態で、図８に示すように、作業者が超音波溶着器８７を開放部４１ｃから空間部Ｓに挿入してＤピラートリム１３の第１溶着凸部３７の先端に当接させ、超音波振動させることにより、Ｄピラートリム１３の第１溶着凸部３７を固定部材２７の第１挿通孔５５周縁に溶着させる。作業者は、超音波溶着器８７が第１突出板部５７に当接したことを認識すると、超音波溶着器８７を第１溶着凸部３７から離し、溶着作業を終了する。このとき、第１挿通孔５５の周縁部が、開放部４１ｃに隣接し、かつ開放部４１ｃ側に向かって座面部４３から遠ざかるように傾斜しているので、第１挿通孔５５の周縁部が超音波溶着器８７に干渉しにくい。したがって、溶着作業が容易である。また、第１挿通孔５５の周縁部に第１突出板部５７が形成されているので、超音波溶着器８７が第１突出板部５７に当接したときに超音波溶着器８７を第１溶着凸部３７から離すようにすることで、第１挿通孔５５の周縁部が溶融し過ぎることを防止できる。また、同様に、Ｄピラートリム１３の第２溶着凸部３９の先端に超音波溶着器８７を当接させ、超音波振動させることにより、Ｄピラートリム１３の第２溶着凸部３７を固定部材２７の第２挿通孔５９周縁に溶着させる。これにより、固定部材２７をＤピラートリム１３に溶着できる。   Next, in a state where the C pillar trim 15 is attached to the C pillar portion of the vehicle body 3, the D pillar trim 13 configured as described above is attached to the roof side rail 5 and the C pillar trim 15 of the vehicle body 3 via the fixing member 27. The installation procedure will be described. First, as shown in FIG. 7, the fixing member 27 is formed in a region excluding the first welding convex portion 37 forming portion and the second welding convex portion 39 forming portion on the front end surfaces of the vertical rib 31 and the horizontal rib 33 of the D pillar trim 13. While making the back surface of the welding surface part 53 contact, the 1st welding convex part 37 of the D pillar trim 13 is inserted in the 1st penetration hole 55 of the fixing member 27, and the 2nd welding convex part 39 of the D pillar trim 13 is made into the fixing member 27 of the fixing member 27. The second insertion hole 59 is inserted. In this state, the first welding convex portion 37 of the D pillar trim 13 protrudes from the first protruding plate portion 57 of the fixing member 27. In this state, as shown in FIG. 8, the operator inserts the ultrasonic welder 87 into the space S from the opening portion 41 c and makes contact with the tip of the first welding convex portion 37 of the D pillar trim 13. The first welding convex portion 37 of the D pillar trim 13 is welded to the periphery of the first insertion hole 55 of the fixing member 27 by ultrasonic vibration. When the operator recognizes that the ultrasonic welder 87 has come into contact with the first protruding plate portion 57, the operator separates the ultrasonic welder 87 from the first weld convex portion 37 and ends the welding operation. At this time, the peripheral edge portion of the first insertion hole 55 is inclined so as to be adjacent to the opening portion 41c and away from the seat surface portion 43 toward the opening portion 41c side. It is difficult to interfere with the ultrasonic welder 87. Therefore, welding work is easy. In addition, since the first protruding plate portion 57 is formed at the peripheral edge portion of the first insertion hole 55, the ultrasonic welder 87 is moved to the first position when the ultrasonic welder 87 contacts the first protruding plate portion 57. By separating from the welding convex part 37, it can prevent that the peripheral part of the 1st penetration hole 55 melt | dissolves too much. Similarly, the ultrasonic welder 87 is brought into contact with the tip of the second weld convex portion 39 of the D pillar trim 13 and is ultrasonically vibrated, whereby the second weld convex portion 37 of the D pillar trim 13 is fixed to the fixing member 27. The second insertion hole 59 is welded to the periphery. Thereby, the fixing member 27 can be welded to the D pillar trim 13.

次に、クリップ２８の第１首部７９を固定部材２７の座面部４３の貫通孔４５に開放口４７から挿入することで、クリップ２８を固定部材２７に取り付ける。   Next, the clip 28 is attached to the fixing member 27 by inserting the first neck 79 of the clip 28 into the through hole 45 of the seating surface portion 43 of the fixing member 27 through the opening 47.

そして、上述のように固定部材２７及びクリップ２８を取り付けたＤピラートリム１３を、クリップ２８の差し込み部７３がルーフサイドレール５の取付孔５ａに対応し、固定部材２７の第１係止部６７がＣピラートリム１５の切欠部１５ａの周縁部に対応し、かつ第２係止部６９がＣピラートリム１５の係止孔１５ｂに対応するようにしてルーフサイドレール５側（上方）に押し付ける。これにより、クリップ２８の爪部７３ｂが取付孔５ａ周縁に当接して内側に撓みながら取付孔５ａを通過し、固定部材２７の第１係止部６７の爪部６７ｂがＣピラートリム１５の切欠部１５ａの周縁部に当接して脚部４１側（図５中右側）に撓みながら切欠部１５ａを通過し、第２係止部６９の爪部６９ｃが係止孔１５ｂの周縁部に当接して脚部４１側（図５中左側）に撓みながら係止孔１５ｂを通過する。そして、クリップ２８の差し込み部７３がルーフサイドレール５の取付孔５ａに挿入係止（係合）され、クリップ２８の当接片部７９がルーフサイドレール５の取付孔５ａの周縁部に車室側から当接する。また、固定部材２７の第１係止部６７がＣピラートリム１５の切欠部１５ａに係止され、第２係止部６９がＣピラートリム１５の係止孔１５ｂに係止される。   Then, the D pillar trim 13 to which the fixing member 27 and the clip 28 are attached as described above, the insertion portion 73 of the clip 28 corresponds to the attachment hole 5a of the roof side rail 5, and the first locking portion 67 of the fixing member 27 is The C pillar trim 15 is pressed against the roof side rail 5 side (upward) so as to correspond to the peripheral edge of the cutout portion 15 a of the C pillar trim 15 and so that the second locking portion 69 corresponds to the locking hole 15 b of the C pillar trim 15. As a result, the claw portion 73b of the clip 28 abuts the periphery of the attachment hole 5a and bends inward to pass through the attachment hole 5a, and the claw portion 67b of the first locking portion 67 of the fixing member 27 15a abuts the peripheral edge of 15a and passes through the notch 15a while bending toward the leg 41 (right side in FIG. 5), and the claw 69c of the second locking part 69 contacts the peripheral edge of the locking hole 15b. It passes through the locking hole 15b while being bent toward the leg 41 side (left side in FIG. 5). Then, the insertion portion 73 of the clip 28 is inserted and locked (engaged) in the mounting hole 5a of the roof side rail 5, and the contact piece 79 of the clip 28 is located on the peripheral edge of the mounting hole 5a of the roof side rail 5. Contact from the side. Further, the first locking portion 67 of the fixing member 27 is locked to the notch portion 15 a of the C pillar trim 15, and the second locking portion 69 is locked to the locking hole 15 b of the C pillar trim 15.

したがって、本実施形態によれば、固定部材２７の脚部４１の内側に溶着箇所を設ける分、取付強度の確保に必要な脚部４１外側の溶着箇所を削減又は廃止できるので、脚部４１の外側に配設する溶着面部５３を縮小又は廃止し、省スペース化を実現できる。   Therefore, according to the present embodiment, since the welding location is provided inside the leg portion 41 of the fixing member 27, the welding location outside the leg portion 41 necessary for securing the mounting strength can be reduced or eliminated. Space-saving can be realized by reducing or eliminating the welding surface portion 53 disposed on the outside.

また、第１挿通孔５５周りの溶着面部５３が脚部４１に囲まれて補強され、撓みにくくなっているので、溶着面部５３の撓みによるＤピラートリム１３のぐらつきが防止される。   Further, since the welding surface portion 53 around the first insertion hole 55 is reinforced by being surrounded by the leg portions 41 and is difficult to bend, the wobbling of the D pillar trim 13 due to the bending of the welding surface portion 53 is prevented.

また、傾斜面部５３ａが開放部４１ｃ側に向かって座面部４３から遠ざかるように座面部４３に対して傾斜しているので、溶着面部５３における脚部４１に囲まれた領域を座面部４３と平行に形成した場合に比べ、溶着面部５３における脚部４１に囲まれた領域と脚部４１との連結部分の長さが長くなる。したがって、脚部４１の剛性が高められ、脚部４１の撓みによるＤピラートリム１３のぐらつきが防止される。   In addition, since the inclined surface portion 53 a is inclined with respect to the seat surface portion 43 so as to be away from the seat surface portion 43 toward the open portion 41 c, the region surrounded by the leg portions 41 in the welding surface portion 53 is parallel to the seat surface portion 43. Compared with the case where it forms, the length of the connection part of the area | region enclosed by the leg part 41 and the leg part 41 in the welding surface part 53 becomes long. Therefore, the rigidity of the leg portion 41 is increased, and the wobble of the D pillar trim 13 due to the bending of the leg portion 41 is prevented.

また、クリップ２８の差し込み部７３が破損したとき、クリップ２８を交換するだけで修理でき、固定部材２７を交換する必要がないので、修理費用を削減できる。   Further, when the insertion portion 73 of the clip 28 is damaged, it can be repaired only by replacing the clip 28, and it is not necessary to replace the fixing member 27, so that the repair cost can be reduced.

また、クリップ２８の爪部７３ｂの撓みやすさを調整する場合にも、クリップ２８を交換するだけで調整でき、固定部材２７を交換する必要がないので、調整費用を削減できる。   Further, when adjusting the ease of bending of the claw portion 73b of the clip 28, it can be adjusted only by replacing the clip 28, and it is not necessary to replace the fixing member 27, so that the adjustment cost can be reduced.

また、固定部材２７の溶着面部５３の第１係止部６７形成箇所及び第２係止部６９形成箇所が脚部４１に近接して補強され、撓みにくくなっているので、溶着面部５３の撓みによるＣピラートリム１５のぐらつきが防止される。   Further, the first locking portion 67 formation portion and the second locking portion 69 formation portion of the welding surface portion 53 of the fixing member 27 are reinforced near the leg portion 41 and are difficult to bend. The wobbling of the C pillar trim 15 due to is prevented.

また、固定部材２７の脚部４１の内側に溶着箇所を設ける分、取付強度の確保に必要な脚部４１外側の溶着箇所が減るので、脚部４１の外側に第１係止部６７及び第２係止部６９の配設スペースを確保しやすい。   Further, since the number of welding locations outside the leg portion 41 necessary for securing the mounting strength is reduced by providing the welding location inside the leg portion 41 of the fixing member 27, the first locking portion 67 and the first engagement portion 67 are provided outside the leg portion 41. It is easy to secure an arrangement space for the two locking portions 69.

なお、本実施形態では、固定部材２７に差し込み部７３を有するクリップ２８を取り付けたが、固定部材２７に係合部としての差し込み部７３を一体に形成してもよい。   In the present embodiment, the clip 28 having the insertion portion 73 is attached to the fixing member 27, but the insertion portion 73 as an engaging portion may be integrally formed with the fixing member 27.

また、本実施形態では、溶着面部５３を脚部４１の他端部から張り出すように形成したが、溶着面部５３における脚部４１に囲まれた領域だけで溶着面部５３を構成してもよい。   In the present embodiment, the welding surface portion 53 is formed so as to protrude from the other end portion of the leg portion 41, but the welding surface portion 53 may be configured only by the region surrounded by the leg portion 41 in the welding surface portion 53. .

また、本実施形態では、溶着面部５３における第１挿通孔５５形成箇所を３方向から囲むように脚部４１を形成したが、２方向から囲むように形成してもよい。   Moreover, in this embodiment, although the leg part 41 was formed so that the 1st insertion hole 55 formation location in the welding surface part 53 might be surrounded from three directions, you may form so that it may surround from two directions.
