Description

本発明は、自動車の車内に取り付けられた内装トリムに、カップホルダーやアームレストなどの内装用部材を精度良く取り付ける構造に関する。
The present invention relates to interior trim attached to the interior of a motor vehicle, it relates the interior member such as a cup holder or armrest accurately mounting structure.

自動車は、様々なユーザーの嗜好に適合させるため、年々、多様化・高品質化が進められていることにより、その車内には、様々なカップホルダーやアームレストなどの内装用部材が取り付けられるようになっており、このような内装用部材を取り付ける構造も数多く開発されている。   In order to adapt to the tastes of various users, automobiles have been diversified and improved in quality year by year so that interior parts such as various cup holders and armrests can be installed inside the car. Many structures for attaching such interior members have been developed.

内装用部材の取り付け構造１の一例として、図１８に示すように、内装用部材２から適宜の箇所において突設された複数の筒状の取付部３と、内装用部材取付孔４が設けられた内装トリム５とを、内装トリム５の裏側から内装用部材取付孔４に挿通したネジ６で螺合する取り付け構造１が挙げられる（特許文献１）。   As an example of the interior member mounting structure 1, as shown in FIG. 18, a plurality of cylindrical mounting portions 3 projecting at appropriate locations from the interior member 2 and interior member mounting holes 4 are provided. There is an attachment structure 1 in which the interior trim 5 is screwed with a screw 6 inserted through the interior trim attachment hole 4 from the back side of the interior trim 5 (Patent Document 1).

特許文献１の取り付け構造１によれば、内装トリム５に設けられた内装用部材取付孔４の位置に応じて、内装トリム５に対する内装用部材２の位置決めをすることができる。
特開２０００−３４３９９７号公報（図３） According to the mounting structure 1 of Patent Document 1, the interior member 2 can be positioned with respect to the interior trim 5 in accordance with the position of the interior member mounting hole 4 provided in the interior trim 5.
JP 2000-343997 A (FIG. 3)

ところが、上述したようにユーザーの嗜好が多様化している現在、同一車種に対して複数のグレードや複数のオプションパーツが用意されることが多く、ユーザーは、自分の嗜好にあったグレードやオプションパーツを選べるようになっている。このため、あるグレードでは内装トリムに取り付けられている内装用部材が、別のグレードでは取り付ける必要がないという場合が当然に生じる。   However, as user preferences have diversified as described above, multiple grades and multiple optional parts are often prepared for the same vehicle type, and users can choose grades and optional parts that suit their preferences. Can be selected. For this reason, the case where an interior member attached to the interior trim in one grade does not need to be attached in another grade naturally occurs.

このような場合、内装用部材２を取り付けるための内装用部材取付孔４が設けられた内装トリム５と、内装用部材取付孔４がない内装トリム５とを予め準備するのはコストアップの原因となることから、内装用部材取付孔４がない内装トリム５のみを準備しておき、必要に応じてプレスやエンドミル加工などといった二次加工によって内装用部材取付孔４を穿設するようにしている。   In such a case, preparing the interior trim 5 provided with the interior member mounting hole 4 for mounting the interior member 2 and the interior trim 5 without the interior member mounting hole 4 in advance causes cost increase. Therefore, only the interior trim 5 without the interior member mounting hole 4 is prepared, and the interior member mounting hole 4 is drilled by secondary processing such as pressing or end milling as necessary. Yes.

しかし、二次加工で穿設した内装用部材取付孔４は、その位置精度が低くなるだけでなく、その断面が真円でなく歪んだ円となる（つまり、真円度が低い）おそれがあり、内装トリム５に設けられた内装用部材取付孔４の位置に応じて内装用部材２の位置が決まる特許文献１の内装用部材２の取り付け構造１では、内装トリム５に対して内装用部材２を精度良く取り付けることができないという問題があった。   However, the interior member mounting hole 4 drilled by the secondary processing not only has a low positional accuracy, but also has a risk that the cross section is not a perfect circle but a distorted circle (that is, the roundness is low). In the mounting structure 1 of the interior member 2 of Patent Document 1 in which the position of the interior member 2 is determined according to the position of the interior member mounting hole 4 provided in the interior trim 5, the interior trim 5 is used for interior. There was a problem that the member 2 could not be attached with high accuracy.

本発明は、このような従来技術の問題に鑑みて開発されたものである。それゆえに本発明の主たる課題は、内装用部材取付孔の位置精度や真円度が低くても内装用部材の取り付け位置精度を高くすることのできる自動車の内装用部材の取り付け構造を提供することにある。
The present invention has been developed in view of such problems of the prior art. Therefore a main object of the present invention provide a mounting structure of the interior member of the vehicle can be positioned accurately and roundness of the interior member mounting hole to improve the mounting position accuracy of the interior member even at low There is.

Further, as shown in FIG. 3, the guide plate 38 b is disposed on the upper side toward the back surface of the interior trim 14, and the guide plate 38 c is disposed on the lower side toward the back side of the interior trim 14. Has been.

ガイド板３８ａ、３８ｂ、３８ｃにおける内装用部材取付孔３４を臨む（「内装用部材取付孔３４を囲む」をも含む概念）面は、それぞれ取付部２０の先端面２０ａをガイドするガイド面４４ａ、４４ｂ、４４ｃとなっている。   The surfaces facing the interior member mounting holes 34 in the guide plates 38a, 38b, and 38c (concepts that also include “surrounding the interior member mounting holes 34”) are guide surfaces 44a that guide the distal end surface 20a of the mounting portion 20, respectively. 44b and 44c.

これらガイド面４４ａ、４４ｂ、４４ｃについて詳述すると、ガイド板３８ａのガイド面４４ａは、図２に示すように、その一方端縁４４ａ１が内装トリム本体３０の裏面に接続されており、他方端縁４４ａ２が当接面４０に接続されている。また、ガイド面４４ａは、一方端縁４４ａ１と他方端縁４４ａ２との間における他方端縁４４ａ２寄りの位置４４ａ３で屈曲され、その断面が「ヘ字状」に形成されている。つまり、ガイド面４４ａは、当接面４０に直交する直交面４６ａと、当接面４０に向けて傾斜する傾斜面４８ａとで構成されている。   The guide surfaces 44a, 44b and 44c will be described in detail. As shown in FIG. 2, the guide surface 44a of the guide plate 38a has one end edge 44a1 connected to the back surface of the interior trim body 30, and the other end edge. 44 a 2 is connected to the contact surface 40. The guide surface 44a is bent at a position 44a3 near the other end edge 44a2 between the one end edge 44a1 and the other end edge 44a2, and its cross section is formed in a “h” shape. That is, the guide surface 44 a includes an orthogonal surface 46 a that is orthogonal to the contact surface 40 and an inclined surface 48 a that is inclined toward the contact surface 40.

ガイド面４４ｂは、図３に示すように、その一方端縁４４ｂ１が内装トリム本体３０の裏面に接続されており、他方端縁４４ｂ２が当接面４０に接続されている。また、ガイド面４４ｂは、一方端縁４４ｂ１と他方端縁４４ｂ２との間における他方端縁４４ｂ２寄りの位置４４ｂ３で屈曲され、その断面が「ヘ字状」に形成されている。つまり、ガイド面４４ｂは、当接面４０に直交する直交面４６ｂと、当接面４０に向けて傾斜する傾斜面４８ｂとで構成されている。   As shown in FIG. 3, the guide surface 44 b has one end edge 44 b 1 connected to the back surface of the interior trim main body 30, and the other end edge 44 b 2 connected to the contact surface 40. The guide surface 44b is bent at a position 44b3 near the other end edge 44b2 between the one end edge 44b1 and the other end edge 44b2, and its cross section is formed in a “h” shape. That is, the guide surface 44 b includes an orthogonal surface 46 b that is orthogonal to the contact surface 40 and an inclined surface 48 b that is inclined toward the contact surface 40.

ガイド面４４ｃは、その一方端縁４４ｃ１が内装トリム本体３０の裏面に接続されており、他方端縁４４ｃ２が当接面４０に接続されている。また、ガイド面４４ｃは、他のガイド面４４ａ、４４ｂとは異なり、その断面は直線状に形成されている。つまり、ガイド面４４ｃは、他のガイド面４４ａ、４４ｂとは異なり、当接面４０に向けて傾斜する傾斜面だけで構成されている。   One end edge 44c1 of the guide surface 44c is connected to the back surface of the interior trim main body 30, and the other end edge 44c2 is connected to the contact surface 40. Further, unlike the other guide surfaces 44a and 44b, the guide surface 44c has a linear cross section. That is, unlike the other guide surfaces 44a and 44b, the guide surface 44c includes only an inclined surface that is inclined toward the contact surface 40.

ガイド面４４ａ、４４ｂ、４４ｃで囲繞された空間の断面は、当接面４０に近づくにつれて小さくなっていき、当接面４０の近傍で当接面４０と同じになる。また、上述したように、当接面４０の一辺の長さは、取付部２０の先端面２０ａの直径よりもやや大きく形成されており、当接面４０の近傍におけるガイド面４４ａ、４４ｂ、４４ｃで囲繞された空間は、ガイド面４４ａ、４４ｂ、４４ｃにガイドされた取付部２０の先端部が嵌入する嵌入部５０となる。   The cross section of the space surrounded by the guide surfaces 44 a, 44 b, 44 c becomes smaller as it approaches the contact surface 40 and becomes the same as the contact surface 40 in the vicinity of the contact surface 40. Further, as described above, the length of one side of the contact surface 40 is slightly larger than the diameter of the tip surface 20a of the mounting portion 20, and the guide surfaces 44a, 44b, 44c in the vicinity of the contact surface 40 are formed. The space surrounded by is a fitting portion 50 into which the tip of the mounting portion 20 guided by the guide surfaces 44a, 44b, 44c is fitted.

次に、内装トリム１４に内装用部材１２を取り付ける手順について説明する。図４に示すように、射出成形された段階の内装トリム１４には内装用部材取付孔３４が設けられていないので、この内装トリム１４に内装用部材１２を取り付ける場合には、プレスやエンドミル加工などといった二次加工により、内装用部材取付孔形成部位Ｒに内装用部材取付孔３４を穿設する。なお、穿設する内装用部材取付孔３４の位置および真円度についての精度は、あまり高く設定する必要がなく、内装トリム１４に対する内装用部材１２の取付精度が１ｍｍ以下のオーダーであれば、数ｍｍオーダーでよい。また、穿設する内装用部材取付孔３４の大きさも内装用部材１２の取付部２０の断面よりも大きく形成されていれば高い精度は必要ない。   Next, a procedure for attaching the interior member 12 to the interior trim 14 will be described. As shown in FIG. 4, since the interior trim 14 at the stage of injection molding is not provided with the interior member attachment hole 34, when the interior member 12 is attached to the interior trim 14, press or end mill processing is performed. The interior member attachment hole 34 is formed in the interior member attachment hole formation region R by secondary processing such as. The accuracy of the position and roundness of the interior member mounting hole 34 to be drilled does not need to be set very high, and if the mounting accuracy of the interior member 12 to the interior trim 14 is on the order of 1 mm or less, It may be on the order of several mm. Further, if the size of the interior member mounting hole 34 to be drilled is formed larger than the cross section of the mounting portion 20 of the interior member 12, high accuracy is not necessary.

穿設された内装用部材取付孔３４に内装用部材１２の取付部２０を挿通すると、取付部２０の先端面２０ａの周縁２０ｂがいずれかのガイド面４４ａ、４４ｂ、４４ｃに当接する。そして、引き続き内装用部材１２を内装トリム１４に向けて移動させていくと、先端面２０ａの周縁２０ｂはいずれかのガイド面４４ａ、４４ｂ、４４ｃ上を摺動し、取付部２０の先端面２０ａは、嵌入部５０に近づいていき、最終的に嵌入部５０に嵌入して当接面４０に当接する。この段階で内装トリム１４に対する内装用部材１２の位置決めが完了する（図５、６参照）。   When the mounting portion 20 of the interior member 12 is inserted into the bored interior member mounting hole 34, the peripheral edge 20b of the distal end surface 20a of the mounting portion 20 comes into contact with any one of the guide surfaces 44a, 44b, 44c. Then, when the interior member 12 is continuously moved toward the interior trim 14, the peripheral edge 20b of the distal end surface 20a slides on any of the guide surfaces 44a, 44b, 44c, and the distal end surface 20a of the mounting portion 20 is moved. Approaches the fitting portion 50, finally fits into the fitting portion 50, and comes into contact with the contact surface 40. At this stage, the positioning of the interior member 12 with respect to the interior trim 14 is completed (see FIGS. 5 and 6).

そして、取付部２０の先端面２０ａを当接面４０に当接させた後、ネジ１５を当接部３６の貫通孔４２から取付部２０の内側にねじ込むことにより、取付部２０の先端面２０ａと当接面４０とを固定する。この段階で内装トリム１４に対する内装用部材１２の取付が完了する（図７、８参照）。   Then, after the front end surface 20a of the attachment portion 20 is brought into contact with the contact surface 40, the screw 15 is screwed into the attachment portion 20 from the through hole 42 of the contact portion 36, whereby the front end surface 20a of the attachment portion 20 is obtained. And the contact surface 40 are fixed. At this stage, the attachment of the interior member 12 to the interior trim 14 is completed (see FIGS. 7 and 8).

このように、内装トリム１４に対する内装用部材１２の位置は、内装用部材１２を取り付ける場合において内装トリム１４に設けられた内装用部材取付孔３４の位置精度等とは関係なく、予め内装トリム１４に設けられた位置決め部材３２によって決められる。このため、二次加工によって設けられた内装用部材取付孔３４の位置精度や真円度が低くても、位置決め部材３２を精度良く形成しておくことにより、内装トリム１４に対する内装用部材１２の取り付け位置精度を高くすることができる。   As described above, the position of the interior member 12 relative to the interior trim 14 is determined in advance regardless of the positional accuracy of the interior member mounting hole 34 provided in the interior trim 14 when the interior member 12 is attached. The positioning member 32 is provided. For this reason, even if the positional accuracy and roundness of the interior member mounting hole 34 provided by the secondary processing are low, the positioning member 32 is formed with high precision, so that the interior member 12 with respect to the interior trim 14 can be formed. Mounting position accuracy can be increased.

また、位置決め部材３２の当接面４０を取付部２０の先端面２０ａに対してネジ１５で固定することにより、位置決め部材３２を介して内装用部材１２を内装トリム１４に固定することができるので、内装トリム１４に取り付けられた内装用部材１２に大きな衝撃が加わったとしても、その衝撃は内装トリム１４の表面に直接加わることがない。このため、内装用部材１２に大きな荷重が加わって内装トリム１４の表面が破損するのを防止することができる。   Further, the interior member 12 can be fixed to the interior trim 14 via the positioning member 32 by fixing the contact surface 40 of the positioning member 32 to the distal end surface 20 a of the mounting portion 20 with the screw 15. Even if a large impact is applied to the interior member 12 attached to the interior trim 14, the impact is not directly applied to the surface of the interior trim 14. For this reason, it is possible to prevent a large load from being applied to the interior member 12 and damage to the surface of the interior trim 14.

なお、本実施例の変形例として、図９に示すように、内装トリム１４の裏側に向かって下側に配設されたガイド板３８ｃのガイド面４４ｃの形状を、他のガイド面４４ａ、４４ｂと同様に、一方端縁４４ｃ１と他方端縁４４ｃ２との間における他方端縁４４ｃ２寄りの位置４４ｃ３で屈曲してその断面を「ヘ字状」に形成し、ガイド面４４ｃを、当接面４０に直交する直交面４６ｃと、当接面４０に向けて傾斜する傾斜面４８ｃとで構成してもよい。この場合、当接面４０、ガイド面４４ｂの直交面４６ｂおよびガイド面４４ｃの直交面４６ｃで囲繞された空間が、取付部２０の先端が嵌入する嵌入部５０となる。   As a modification of the present embodiment, as shown in FIG. 9, the shape of the guide surface 44c of the guide plate 38c disposed on the lower side toward the back side of the interior trim 14 is changed to the other guide surfaces 44a, 44b. In the same manner as above, the cross section is bent at a position 44c3 between the one end edge 44c1 and the other end edge 44c2 and close to the other end edge 44c2, and the cross section thereof is formed into a “h” shape. You may comprise by the orthogonal surface 46c orthogonal to, and the inclined surface 48c which inclines toward the contact surface 40. FIG. In this case, the space surrounded by the contact surface 40, the orthogonal surface 46b of the guide surface 44b, and the orthogonal surface 46c of the guide surface 44c becomes the fitting portion 50 into which the tip of the mounting portion 20 is fitted.

また、他の変形例として、図１０に示すように、ガイド板３８ｂのガイド面４４ｂを当接面４０に向けて傾斜する傾斜面としてもよい。この場合、当接面４０、ガイド面４４ｂおよびガイド面４４ｃで囲繞された空間のうち当接面４０の近傍部分が、取付部２０の先端が嵌入する嵌入部５０となる。   As another modification, the guide surface 44b of the guide plate 38b may be an inclined surface that is inclined toward the contact surface 40 as shown in FIG. In this case, in the space surrounded by the contact surface 40, the guide surface 44b, and the guide surface 44c, a portion in the vicinity of the contact surface 40 becomes the fitting portion 50 into which the tip of the mounting portion 20 is fitted.

さらに、他の変形例として、図１１に示すように、ガイド板３８ｂのガイド面４４ｂを２箇所（４４ｂ３および４４ｂ４）で屈曲させることにより、直交面４６ｂ、傾斜面４８ｂ、および直交面４６ｂと傾斜面４８ｂとの間に配設され、当接面４０に平行な平行面５２ｂで構成し、同様にして、ガイド板３８ｃのガイド面４４ｃも直交面４６ｂ、傾斜面４８ｂ、および直交面４６ｃと傾斜面４８ｃとの間に配設され、当接面４０に平行な平行面５２ｃで構成してもよい。この場合、当接面４０、ガイド面４４ｂの直交面４６ｂおよびガイド面４４ｃの直交面４６ｃで囲繞された空間が、取付部２０の先端が嵌入する嵌入部５０となる。   Furthermore, as another modified example, as shown in FIG. 11, the guide surface 44b of the guide plate 38b is bent at two locations (44b3 and 44b4), so that the orthogonal surface 46b, the inclined surface 48b, and the orthogonal surface 46b are inclined. Similarly, the guide surface 44c of the guide plate 38c is inclined with the orthogonal surface 46b, the inclined surface 48b, and the orthogonal surface 46c. You may comprise between the surface 48c and the parallel surface 52c parallel to the contact surface 40. In this case, the space surrounded by the contact surface 40, the orthogonal surface 46b of the guide surface 44b, and the orthogonal surface 46c of the guide surface 44c becomes the fitting portion 50 into which the tip of the mounting portion 20 is fitted.

上記変形例は、位置決め部材３２の略角錐台形状の上下側面であるガイド板３８ｂ、３８ｃを用いて説明したが、これらの変形例を略角錐台形状の左右側面にあるガイド板３８ａに適用することもできる。   Although the said modification was demonstrated using the guide plates 38b and 38c which are the upper and lower sides of the substantially pyramidal shape of the positioning member 32, these modifications are applied to the guide plates 38a which are on the left and right sides of the substantially pyramidal shape. You can also.

（第２の実施例）
第２の実施例に係る自動車の内装用部材の取り付け構造１０（図１２〜図１３）は、第１の実施例と同じく、内装用部材１２を自動車の車内に取り付けられる内装トリム１４に取り付ける構造であるが、内装用部材１２の取付部２０の先端部が当接部３６に設けられた嵌込孔６４に嵌め込まれる点が第１の実施例と相違している。 (Second embodiment)
An automobile interior member mounting structure 10 (FIGS. 12 to 13) according to the second embodiment is the same as the first embodiment, in which the interior member 12 is attached to an interior trim 14 attached to the interior of the automobile. However, it differs from the first embodiment in that the tip of the mounting portion 20 of the interior member 12 is fitted into the fitting hole 64 provided in the contact portion 36.

内装用部材１２は、ポリプロピレン（もちろん、ＡＢＳ樹脂、アクリル樹脂、ポリカーボネート、金属など他の材質を用いてもよい）を射出成形して製造されており、内装用部材本体１６と、基部１８と、取付部２０と、横方向補強部材２２と、縦方向補強部材２４と、内装トリム１４の表面に当接する内装トリム当接部２５とで一体に形成されている。   The interior member 12 is manufactured by injection-molding polypropylene (of course, other materials such as ABS resin, acrylic resin, polycarbonate, metal, etc.), and includes an interior member body 16, a base 18, The mounting portion 20, the lateral reinforcing member 22, the vertical reinforcing member 24, and the interior trim contact portion 25 that contacts the surface of the interior trim 14 are integrally formed.

内装用部材本体１６には、上述したように、内装用部材本体１６から水平に延出された、図示しないトノカバーを載置するための載置部２６と、載置したトノカバーを係止するための係止ピン２８とが一体に形成されている。   As described above, the interior member main body 16 extends horizontally from the interior member main body 16 to hold the placement portion 26 for placing a tonneau cover (not shown) and the placed tonneau cover. The locking pin 28 is integrally formed.

取付部２０は、内装用部材本体１６に一体に形成された基部１８をベースとして内装用部材１２から突設された段付きの円柱部材であり、内装用部材１２から突設された円柱状の基部太軸部６０と、基部太軸部６０の先端面６０ａから突設され、基部太軸部６０よりも細く形成された円柱状の先端細軸部６２とで構成されており、基部太軸部６０の先端面６０ａと先端細軸部６２の側面とで段が形成されている。また、先端細軸部６２の長さは、後述する位置決め部材３２の当接部３６の厚みよりも長く形成されている。なお、取付部２０の形状は、角柱状であってもよい。   The mounting portion 20 is a stepped columnar member projecting from the interior member 12 with a base 18 formed integrally with the interior member body 16 as a base, and a columnar member projecting from the interior member 12. The base thick shaft portion 60 and a columnar tip thin shaft portion 62 projecting from the distal end surface 60a of the base thick shaft portion 60 and formed narrower than the base thick shaft portion 60 are configured. A step is formed by the tip surface 60 a of the portion 60 and the side surface of the tip thin shaft portion 62. Moreover, the length of the distal end thin shaft portion 62 is formed to be longer than the thickness of a contact portion 36 of a positioning member 32 described later. Note that the shape of the mounting portion 20 may be a prismatic shape.

横方向補強部材２２および縦方向補強部材２４は、基部１８に対する取付部２０の取り付け強度を高めるため、取付部２０を中心として放射状に設けられたリブである。
The horizontal direction reinforcing member 22 and the vertical direction reinforcing member 24 are ribs provided radially around the mounting portion 20 in order to increase the mounting strength of the mounting portion 20 with respect to the base portion 18.

内装トリム１４は、自動車の内面に取り付けられる内張り材であり、内装用部材１２と同様に、ポリプロピレン（もちろん、ＡＢＳ樹脂、アクリル樹脂、ポリカーボネート、金属など他の材質を用いてもよい）を射出成形して製造されており、内装トリム本体３０と位置決め部材３２と、内装トリム本体３０に対する位置決め部材３２の取り付け強度を高めるために設けられた補強部材３３とで一体に形成されている。
The interior trim 14 is a lining material that is attached to the inner surface of the automobile, and like the interior member 12, polypropylene (of course, other materials such as ABS resin, acrylic resin, polycarbonate, metal, etc. may be used) is injection molded. The interior trim main body 30, the positioning member 32, and the reinforcing member 33 provided to increase the attachment strength of the positioning member 32 to the interior trim main body 30 are integrally formed.

また、内装トリム１４には、内装用部材１２の取付部２０を挿通するための内装用部材取付孔３４が穿設されているが、射出成形によって製造された段階の内装トリム１４には、この内装用部材取付孔３４が形成されておらず、内装用部材１２を取り付ける場合にのみ、プレスやエンドミル加工などといった二次加工によって内装トリム１４に内装用部材取付孔３４が穿設される。   The interior trim 14 has an interior member mounting hole 34 for inserting the mounting portion 20 of the interior member 12. The interior trim 14 at the stage of being manufactured by injection molding includes The interior member mounting hole 34 is not formed, and the interior member mounting hole 34 is formed in the interior trim 14 by secondary processing such as pressing or end milling only when the interior member 12 is mounted.

位置決め部材３２は、内装トリム１４に対する内装用部材１２の位置決めを行うための部材であり、内装トリム１４の裏面（内装用部材１２が取り付けられる面と反対の面）において、内装用部材取付孔３４を臨む位置に設けられている（なお、「内装用部材取付孔３４を臨む位置」とは、「内装用部材取付孔３４を囲む位置」をも含む概念である。）。   The positioning member 32 is a member for positioning the interior member 12 with respect to the interior trim 14, and the interior member mounting hole 34 is provided on the back surface (the surface opposite to the surface on which the interior member 12 is attached) of the interior trim 14. ("The position facing the interior member mounting hole 34" is a concept including "a position surrounding the interior member mounting hole 34").

また、位置決め部材３２は、略角錐台形状に形成されており、この略角錐台形状の天面にあたる当接部３６と、側面にあたるガイド部３８とを有している。また、ガイド部３８の底端（つまり、略角錐台形状の底）は、内装トリム本体３０の裏面に一体的に接続されている。なお、位置決め部材３２の形状は、略円錐台形状であってもよい。   The positioning member 32 is formed in a substantially truncated pyramid shape, and includes a contact portion 36 corresponding to the top surface of the substantially truncated pyramid shape and a guide portion 38 corresponding to the side surface. Further, the bottom end of the guide portion 38 (that is, the bottom having a substantially truncated pyramid shape) is integrally connected to the back surface of the interior trim body 30. The shape of the positioning member 32 may be a substantially truncated cone shape.

当接部３６は、内装用部材取付孔３４が設けられた場合、当該内装用部材取付孔３４に対向する位置に配設された板材であり、その略中央部には、取付部２０の先端細軸部６２が嵌め込まれる嵌込孔６４が挿入方向Ｚに設けられている。また、前述したように、取付部２０の先端細軸部６２の長さは、当接部３６の厚みよりも長く形成されているので、嵌込孔６４に嵌め込まれた先端細軸部６２の先端部は、嵌込孔６４から露出するようになる。また、当接部３６における内装用部材取付孔３４に対向する面は、嵌込孔６４に取付部２０の先端細軸部６２が嵌め込まれたとき、取付部２０の基部太軸部６０の先端面６０ａと当接する当接面４０となっている。   When the interior member mounting hole 34 is provided, the abutting portion 36 is a plate material disposed at a position facing the interior member mounting hole 34. A fitting hole 64 into which the thin shaft portion 62 is fitted is provided in the insertion direction Z. Further, as described above, since the length of the distal end thin shaft portion 62 of the mounting portion 20 is formed to be longer than the thickness of the abutting portion 36, the distal end thin shaft portion 62 fitted in the insertion hole 64 has a length. The tip end portion is exposed from the fitting hole 64. Further, the surface of the abutment portion 36 that faces the interior member attachment hole 34 is the tip of the base thick shaft portion 60 of the attachment portion 20 when the tip thin shaft portion 62 of the attachment portion 20 is fitted in the fitting hole 64. The contact surface 40 is in contact with the surface 60a.

当接面４０は、略正方形状（位置決め部材３２が略円錐台形状である場合には、略円形状）に形成されており、その一辺の長さは、取付部２０における基部太軸部６０の先端面６０ａの直径よりもやや大きく形成されている。また、当接面４０と内装トリム本体３０との距離は、基部太軸部６０の先端面６０ａが当接面４０に当接したとき、内装用部材１２の横方向補強部材２２の内装トリム側端縁２２ａや内装トリム当接部２５の内装トリム側端縁２５ａが内装トリム本体３０の表面（内装用部材１２が取り付けられる側の面）に当接するように設定されている。   The contact surface 40 is formed in a substantially square shape (a substantially circular shape when the positioning member 32 has a substantially truncated cone shape), and the length of one side thereof is the base thick shaft portion 60 in the mounting portion 20. The tip surface 60a is slightly larger than the diameter. Further, the distance between the abutment surface 40 and the interior trim main body 30 is such that when the distal end surface 60a of the base thick shaft portion 60 abuts against the abutment surface 40, the interior trim side of the lateral reinforcing member 22 of the interior member 12 The edge 22a and the interior trim side edge 25a of the interior trim contact portion 25 are set so as to contact the surface of the interior trim main body 30 (the surface on the side where the interior member 12 is attached).

ガイド部３８は、上述したように、略角錐台形状（あるいは略円錐台形状）の位置決め部材３２の側面にあたり、３つのガイド板３８ａ、３８ｂ、３８ｃを組み合わせて形成されている。このため、略角錐台形状を構成する４つの側面中の１面には、ガイド板が配設されていないことになる。なお、このようにしたのは、射出成型時における型抜きのし易さを考慮したものであり、射出成形後に４つ目の側面にガイド板を取り付け、位置決め部材３２の略角錐台形状を構成する全ての側面にガイド板を配設するようにしてもよい。   As described above, the guide portion 38 is formed by combining three guide plates 38a, 38b, and 38c on the side surface of the positioning member 32 having a substantially truncated pyramid shape (or substantially truncated cone shape). For this reason, the guide plate is not disposed on one of the four side surfaces constituting the substantially truncated pyramid shape. Note that this was done in consideration of the ease of punching during injection molding, and a guide plate was attached to the fourth side surface after injection molding to form a substantially pyramidal shape of the positioning member 32. Guide plates may be provided on all side surfaces.

ガイド板３８ａは、図１２に示すように、内装トリム１４の裏面に向かって左側に配設されている。また、ガイド板３８ｂは、図１３に示すように、内装トリム１４の裏面に向かって上側に配設されており、さらに、ガイド板３８ｃは、内装トリム１４の裏側に向かって下側に配設されている。   As shown in FIG. 12, the guide plate 38 a is disposed on the left side toward the back surface of the interior trim 14. Further, as shown in FIG. 13, the guide plate 38 b is disposed on the upper side toward the back surface of the interior trim 14, and the guide plate 38 c is disposed on the lower side toward the back side of the interior trim 14. Has been.

ガイド板３８ａ、３８ｂ、３８ｃの内装用部材取付孔３４を臨む面は、それぞれ取付部２０の先端面２０ａをガイドするガイド面４４ａ、４４ｂ、４４ｃとなっている。   The surfaces of the guide plates 38a, 38b, and 38c facing the interior member mounting holes 34 are guide surfaces 44a, 44b, and 44c that guide the distal end surface 20a of the mounting portion 20, respectively.

これらガイド面４４ａ、４４ｂ、４４ｃについて詳述すると、ガイド板３８ａのガイド面４４ａは、図１２に示すように、その一方端縁４４ａ１が内装トリム本体３０の裏面に接続されており、他方端縁４４ａ２が当接面４０に接続されている。また、ガイド面４４ａは、一方端縁４４ａ１と他方端縁４４ａ２との間における他方端縁４４ａ２寄りの位置４４ａ３で屈曲され、その断面が「ヘ字状」に形成されている。つまり、ガイド面４４ａは、当接面４０に直交する直交面４６ａと、当接面４０に向けて傾斜する傾斜面４８ａとで構成されている。   The guide surfaces 44a, 44b and 44c will be described in detail. As shown in FIG. 12, the guide surface 44a of the guide plate 38a has one end edge 44a1 connected to the back surface of the interior trim body 30, and the other end edge. 44 a 2 is connected to the contact surface 40. The guide surface 44a is bent at a position 44a3 near the other end edge 44a2 between the one end edge 44a1 and the other end edge 44a2, and its cross section is formed in a “h” shape. That is, the guide surface 44 a includes an orthogonal surface 46 a that is orthogonal to the contact surface 40 and an inclined surface 48 a that is inclined toward the contact surface 40.

ガイド面４４ｂは、図１３に示すように、その一方端縁４４ｂ１が内装トリム本体３０の裏面に接続されており、他方端縁４４ｂ２が当接面４０に接続されている。また、ガイド面４４ｂは、一方端縁４４ｂ１と他方端縁４４ｂ２との間における他方端縁４４ｂ２寄りの位置４４ｂ３で屈曲され、その断面が「ヘ字状」に形成されている。つまり、ガイド面４４ｂは、当接面４０に直交する直交面４６ｂと、当接面４０に向けて傾斜する傾斜面４８ｂとで構成されている。   As shown in FIG. 13, one end edge 44 b 1 of the guide surface 44 b is connected to the back surface of the interior trim main body 30, and the other end edge 44 b 2 is connected to the contact surface 40. The guide surface 44b is bent at a position 44b3 near the other end edge 44b2 between the one end edge 44b1 and the other end edge 44b2, and its cross section is formed in a “h” shape. That is, the guide surface 44 b includes an orthogonal surface 46 b that is orthogonal to the contact surface 40 and an inclined surface 48 b that is inclined toward the contact surface 40.

また、ガイド面４４ｃも同様に、その一方端縁４４ｃ１が内装トリム本体３０の裏面に接続されており、他方端縁４４ｃ２が当接面４０に接続されている。また、ガイド面４４ｃは、一方端縁４４ｃ１と他方端縁４４ｃ２との間における他方端縁４４ｃ２寄りの位置４４ｃ３で屈曲され、その断面が「ヘ字状」に形成されている。つまり、ガイド面４４ｃは、当接面４０に直交する直交面４６ｃと、当接面４０に向けて傾斜する傾斜面４８ｃとで構成されている。   Similarly, one end edge 44 c 1 of the guide surface 44 c is connected to the back surface of the interior trim main body 30, and the other end edge 44 c 2 is connected to the contact surface 40. Further, the guide surface 44c is bent at a position 44c3 between the one end edge 44c1 and the other end edge 44c2 and close to the other end edge 44c2, and the cross section is formed in a “h” shape. That is, the guide surface 44 c includes an orthogonal surface 46 c that is orthogonal to the contact surface 40 and an inclined surface 48 c that is inclined toward the contact surface 40.

このように、ガイド面４４ａ、４４ｂ、４４ｃで囲繞された空間の断面は、当接面４０に近づくにつれて小さくなっていき、当接面４０の近傍で当接面４０と同じになる。また、上述したように、当接面４０の一辺の長さは、基部太軸部６０の先端面６０ａの直径よりもやや大きく形成されている。   As described above, the cross section of the space surrounded by the guide surfaces 44 a, 44 b, 44 c becomes smaller as it approaches the contact surface 40 and becomes the same as the contact surface 40 in the vicinity of the contact surface 40. Further, as described above, the length of one side of the contact surface 40 is formed to be slightly larger than the diameter of the distal end surface 60 a of the base thick shaft portion 60.

次に、内装トリム１４に内装用部材１２を取り付ける手順について説明する。射出成形された段階の内装トリム１４は、内装用部材取付孔３４が設けられていないので、この内装トリム１４に内装用部材１２を取り付ける場合には、プレスやエンドミル加工などといった二次加工により、所定の位置に内装用部材取付孔３４を穿設する。なお、穿設する内装用部材取付孔３４の位置および真円度についての精度は、あまり高く設定する必要がなく、内装トリム１４に対する内装用部材１２の取付精度が１ｍｍ以下のオーダーであれば、数ｍｍオーダーでよい。また、穿設する内装用部材取付孔３４の大きさも内装用部材１２の取付部２０における基部太軸部６０の断面よりも大きく形成されていれば高い精度は必要ない。   Next, a procedure for attaching the interior member 12 to the interior trim 14 will be described. Since the interior trim 14 at the stage of injection molding is not provided with the interior member mounting hole 34, when the interior member 12 is attached to the interior trim 14, by secondary processing such as pressing or end milling, An interior member mounting hole 34 is formed at a predetermined position. The accuracy of the position and roundness of the interior member mounting hole 34 to be drilled does not need to be set very high, and if the mounting accuracy of the interior member 12 to the interior trim 14 is on the order of 1 mm or less, It may be on the order of several mm. Further, if the size of the interior member mounting hole 34 to be drilled is formed larger than the cross section of the base thick shaft portion 60 in the mounting portion 20 of the interior member 12, high accuracy is not necessary.

穿設された内装用部材取付孔３４に内装用部材１２の取付部２０を挿通すると、取付部２０における先端細軸部６２の先端面６２ａの周縁６２ｂがいずれかのガイド面４４ａ、４４ｂ、４４ｃに当接する。そして、引き続き内装用部材１２を内装トリム１４に向けて移動させていくと、先端細軸部６２の先端面６２ａの周縁６２ｂが当該ガイド面４４ａ、４４ｂあるいは４４ｃ上を摺動することにより、先端細軸部６２の先端は、当接部３６に設けられた嵌込孔６４に近づき、当接面４０上を摺動して最終的に嵌込孔６４に嵌入する（図１４、１５参照）。   When the mounting portion 20 of the interior member 12 is inserted into the bored interior member mounting hole 34, the peripheral edge 62b of the distal end surface 62a of the distal end thin shaft portion 62 in the mounting portion 20 is one of the guide surfaces 44a, 44b, 44c. Abut. When the interior member 12 is continuously moved toward the interior trim 14, the peripheral edge 62b of the distal end surface 62a of the distal end thin shaft portion 62 slides on the guide surface 44a, 44b or 44c, thereby The tip of the thin shaft portion 62 approaches the fitting hole 64 provided in the contact portion 36, slides on the contact surface 40, and finally fits into the fitting hole 64 (see FIGS. 14 and 15). .

さらに、内装用部材１２を内装トリム１４に向けて移動させていくと、先端細軸部６２の先端部が嵌込孔６４から露出し、基部太軸部６０の先端面６０ａが当接面４０に当接する。この段階で内装トリム１４に対する内装用部材１２の位置決めが完了する（図１６、１７参照）。   Further, when the interior member 12 is moved toward the interior trim 14, the distal end portion of the distal thin shaft portion 62 is exposed from the fitting hole 64, and the distal end surface 60 a of the base thick shaft portion 60 is contacted with the contact surface 40. Abut. At this stage, the positioning of the interior member 12 with respect to the interior trim 14 is completed (see FIGS. 16 and 17).

そして、嵌込孔６４から露出した先端細軸部６２の先端部に予め熱しておいたリベット工具７０を押しつけることにより、先端細軸部６２の先端部６２ｃを変形させて締め付け頭７２を形成する。締め付け頭７２を形成することによって先端細軸部６２が位置決め部材３２に固定され、この段階で内装トリム１４に対する内装用部材１２の取付が完了する。   Then, by pressing a rivet tool 70 that has been heated in advance against the tip end of the tip thin shaft portion 62 exposed from the fitting hole 64, the tip portion 62c of the tip thin shaft portion 62 is deformed to form a tightening head 72. . By forming the fastening head 72, the distal thin shaft portion 62 is fixed to the positioning member 32, and the attachment of the interior member 12 to the interior trim 14 is completed at this stage.

このように、内装トリム１４に対する内装用部材１２の位置は、内装用部材１２を取り付ける場合において内装トリム１４に設けられた内装用部材取付孔３４の位置精度等とは関係なく、予め内装トリム１４に設けられた位置決め部材３２によって決められる。このため、二次加工によって設けられた内装用部材取付孔３４の位置精度や真円度が低くても、位置決め部材３２を精度良く形成しておくことにより、内装トリム１４に対する内装用部材１２の取り付け位置精度を高くすることができる。   As described above, the position of the interior member 12 relative to the interior trim 14 is determined in advance regardless of the positional accuracy of the interior member mounting hole 34 provided in the interior trim 14 when the interior member 12 is attached. The positioning member 32 is provided. For this reason, even if the positional accuracy and roundness of the interior member mounting hole 34 provided by the secondary processing are low, the positioning member 32 is formed with high precision, so that the interior member 12 with respect to the interior trim 14 can be formed. Mounting position accuracy can be increased.

また、取付部２０の先端細軸部６２を位置決め部材に固定することにより、位置決め部材３２を介して内装用部材１２を内装トリム１４に固定することができるので、内装トリム１４に取り付けられた内装用部材１２に大きな衝撃が加わったとしても、その衝撃は内装トリム１４の表面に直接加わることがない。このため、内装用部材１２に大きな荷重が加わって内装トリム１４の表面が破損するのを防止することができる。   Further, by fixing the distal end thin shaft portion 62 of the mounting portion 20 to the positioning member, the interior member 12 can be fixed to the interior trim 14 via the positioning member 32, so that the interior mounted on the interior trim 14 Even if a large impact is applied to the member 12, the impact is not directly applied to the surface of the interior trim 14. For this reason, it is possible to prevent a large load from being applied to the interior member 12 and damage to the surface of the interior trim 14.

本実施例では、先端細軸部６２を位置決め部材３２に固定する方法としてリベット締めする場合について説明したが、当該方法はこれに限定されるものではなく、例えば、先端細軸部６２と当接部３６の嵌込孔６４とを締まり嵌めにしてもよいし、先端細軸部６２と当接部３６とを熱融着してもよい。   In the present embodiment, the case where the tip thin shaft portion 62 is riveted as a method of fixing the distal end thin shaft portion 62 to the positioning member 32 has been described. However, the method is not limited to this. The fitting hole 64 of the portion 36 may be an interference fit, or the distal thin shaft portion 62 and the contact portion 36 may be heat-sealed.
