この発明は自動車に最適な単体外板の取付構造に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Application in Industry] The present invention relates to a mounting structure for a single outer panel most suitable for automobiles.
一般に自動車に樹脂を用いることは、自動車工学仝占第
１３巻「乗用車の車体」 （山海堂出版）に訂しく述べ
られている。In general, the use of resin in automobiles is clearly stated in Automotive Engineering Book Volume 13, ``Passenger Car Bodies'' (Sankaido Publishing).
従来における小体外板の構造としては、例えば、第６図

で取イ１ける固定タイプが知られている。For example, as shown in FIG. 6, the structure of a conventional small body skin is such that tm
3 to the vehicle body structure part 105 with bolts 107 and nuts 109
A fixed type is known that can be used for up to 1 hours.
この固定タイプは、車体外板１０１が合成樹脂製の場合
に、外気温によって伸縮するところから、伸縮の繰返し
により車体外板１０１に変形歪が発生し外観不良となる
恐れがあった。In this fixed type, when the vehicle body outer panel 101 is made of synthetic resin, it expands and contracts depending on the outside temperature, so repeated expansion and contraction may cause deformation and strain in the vehicle body outer panel 101, resulting in poor appearance.
そこで、前記問題を解消する手段として、例えば、第４

。Therefore, as a means to solve the above problem, for example, the fourth
Attachment of the vehicle body outer plate 101 (flange 103 or vehicle body structure
At least one of the mounting holes 111 and 113 of 05 is made into a long hole shape, and each mounting hole 111 and
1 to 1 to the threaded part of the bolt 107 inserted into 113.
09 is screwed and fixed, and the vehicle body outer plate 10 is fixed within the range of the elongated hole.
One possible method is to absorb the movement of 1 (in the direction of the arrow).

する等の問題が起きる。This means absorbs the amount of movement of the vehicle body outer plate 101 so that no unreasonable load is applied to the mounting flange 103 and no deformation strain occurs.
The contact surface of the vehicle body outer plate 105 that comes into contact with the flange 103 will cause the paint film to peel off, which is not desirable in terms of rust prevention. Therefore, sealing defects are likely to occur.Furthermore, in the case of J:, problems such as a5 being within the range of the elongated hole may cause the vehicle body outer panel 101 to rattle, resulting in quality deterioration.
そこで、この発明は外観品質を確保すると共に、しかも

にわたって屈曲可能な薄肉部を設けである。In order to achieve the above-mentioned object, the present invention provides a structure in which a flange is fixed to the vehicle body structure for attaching a vehicle body outer panel made of a material such as a synthetic resin, and a flange is attached from the main body of the vehicle body outer panel. A bendable thin portion is provided at least over a corner region in a portion continuing to the corner portion.

取付はフランジ及び主体部に無理な負荷は加わらず変形
歪は起きない。For example, when the vehicle body outer panel expands due to the influence of the outside temperature, the corner portion bends to accommodate the movement and absorb the expansion. This closed mounting does not apply excessive load to the flange or main body, and does not cause deformation or strain.
（実施例〕
以下、第１図の図面を参照しながらこの発明の一実施例
を詳細に説明する。(Embodiment) Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawing of FIG.
図中１は車体構造部を示しており、該車体構造部１には
車体外板３が取イ」けられている。In the figure, numeral 1 indicates a vehicle body structure, and a vehicle body outer plate 3 is attached to the vehicle body structure 1.
車体外板３は合成樹脂等の材質で形成され、車中方向に
長い主体部５と、該主体部５より突出（図面上方）され
た突出部７と、該突出部７より屈曲された取付はフラン
ジ９とから成っている。The vehicle body outer panel 3 is made of a material such as synthetic resin, and includes a main body portion 5 that is long in the direction of the interior of the vehicle, a protrusion portion 7 that protrudes from the main body portion 5 (upward in the drawing), and a mounting portion that is bent from the protrusion portion 7. consists of a flange 9.
取付はフランジ９は、該フランジ９と車体構造部１に穿
設された各取イ」孔１１・１１にシールパツキン１３を
介してボルト１５が貫通され、該ボルト１５のねじ部に
螺合されたナツト１７によって車体構造部１に固着され
ている。To install the flange 9, bolts 15 are passed through the holes 11, 11 drilled in the flange 9 and the vehicle body structure 1 through the seal packing 13, and screwed into the threaded portions of the bolts 15. It is fixed to the vehicle body structure 1 by a nut 17.
一方、前記車体外板３の主体部５から取イζ」けフラン
ジ９へ続く部位、即ち、突出部７の全領域にわたる板厚
【は生体部５の板厚Ｔに対して薄肉部１つとなっている
。これにより、各コーナ部ａ。On the other hand, the thickness of the portion of the vehicle body outer panel 3 continuing from the main body portion 5 to the flange 9, that is, the entire region of the protruding portion 7, is one thin portion compared to the thickness T of the living body portion 5. It has become. As a result, each corner portion a.
ｂは薄肉部１９によって屈曲可能なヒンジ機能が１４ら
れる形状となっている。b has a shape in which a bendable hinge function 14 is provided by a thin wall portion 19.
このように構成された車体外板３の取付構造において、
例えば、車体外板３が外気温の影響で膨張すると、取付

収し主体部５は動くようになる。このため、取付はフラ
ンジ９に無ｌＴな負荷は作用しないためシール不良は起
きず、また、変形歪の発生もない。In the mounting structure for the vehicle body outer plate 3 configured in this way,
For example, when the vehicle body outer panel 3 expands due to the influence of outside temperature, the main body portion 5 expands in the direction of arrow A since the attached flange 9 is in a fixed state. At this time, the thin protruding portion 7 is bent at the corner portions a and b, bends as shown by the chain line, absorbs the bending motion, and the main body portion 5 begins to move. Therefore, during installation, no load is applied to the flange 9, so sealing failure does not occur, and deformation strain does not occur.
この場合、突出部７の板厚［を主体部５の板厚Ｔ ニ対
し、てｔ＜２Ｔ／３の関係に設定すると共に突出部７の
長さＤを、Ｄ＞ＩＯＴの関係に設定した所、主体部５の
伸縮時に突出部７がコーナ部ａ。In this case, the plate thickness of the protrusion 7 is set to the plate thickness T of the main body part 5 in the relationship t<2T/3, and the length D of the protrusion 7 is set in the relationship D>IOT. However, when the main body portion 5 expands and contracts, the protruding portion 7 is at the corner portion a.
ｂより無理なく撓むことが判明し主体部５の動き市を確
実に吸収する好結果が得られた。It was found that the main body part 5 was able to bend more easily than b, and a good result was obtained in which the movement of the main body part 5 was reliably absorbed.

に設定した所一番良い実験結果が得られた。Further, as shown in FIG. 2, the main body portion 5 and the mounting may be provided with thin wall portions 19, 19 in the corner portions a and b following the flange 9, or as shown in FIG. Corner parts d and c are also provided almost in the middle of the protruding part 7, and thin parts 19 and 19 are provided in each corner part d and c area (where
Good results similar to those of the previous example were obtained. In addition, in the embodiment shown in FIG. 3, the best experimental results were obtained when the distance from both ends of the main body part 5 of the vehicle body outer panel 3 to the points 1-15 was set to approximately 5 mm. was gotten.

Since the darkness can be absorbed by the thin parts, no deformation distortion occurs on the outer skin of the car body. As a result, the appearance quality will not deteriorate by 10%. In addition, since no unreasonable load is applied to the mounting flange, the flange can be securely fixed around the mounting points, and a stable sealing state can be maintained for a long period of time.
