。(Prior art) Recently, in order to reduce the weight of automobile bodies,
Plastic-covered roof panels are sometimes used for roof panels that make up the roof of the vehicle (Utility Model Publication No. 58-82991).
(Refer to the publication number, etc.) The plastic roof panel (hereinafter referred to as the "Plus Deck Roof") can be attached to the metal roof frame of the car body by mechanical joining using bolts with rivets, or by adhesive bonding. There are two methods: a joining method and a method that uses both.

フレームとの接合部が破１０シたりするという問題があ
る。(Problems that the invention is unable to solve) By the way, if the material r1 of the above-mentioned plus deck roof is U,
FRP, especially its most typical glass fiber content 3
When using 0% SMC (sheet sailing compound), its linear expansion coefficient is approximately 14X10-6
(/'C), and the linear expansion coefficient of metal, such as steel, which is the constituent material of the roof frame when the plus deck roof is installed (approx. 12x10-6 (,/'C)
) is approximately equal to However, when using a clear plastic such as acrylic resin or PC (polycarbonate 1-), its linear expansion coefficient is approximately 66-70X10-G.
(/°C), and there is a considerable difference between the coefficient of linear expansion and that of steel. Therefore, there are problems in that the plastic roof may undergo abnormal deformation due to thermal expansion, or the joint between the plastic roof and the roof frame may break.
このような問題を解決するためには、プラスチックルー

ボルト止め箇所間の長さが長くなるため、温度上界時に
その部分でプラスブックルーフが人さく浮き上がり、プ
ラスチックルーフ全体が波打つような変形−を生じるの
で実施づることはできない。In order to solve these problems, it is necessary to reduce the rigidity of the joint between the plastic roof and the metal roof frame, and to absorb and alleviate the difference in thermal expansion between the two. . As a concrete solution to this problem, for example, in the case of bolted joints, it is conceivable to reduce the number of bolts vi (bolts/fastening points). But in this case,
Since the length between the bolted parts becomes long, the plastic roof will lift up at that part when the temperature reaches its upper limit, causing the entire plastic roof to become wavy and deformed, so this method cannot be implemented.
また、接着接合の場合、従来使用しでいる接着剤に比べ

という問題がある。Furthermore, in the case of adhesive bonding, it is conceivable to use an adhesive that is softer than the adhesives that have been used conventionally. but,
At this time, gently touch the entire periphery of the plastic roof with 1S.
If the plastic roof were to be adhesively bonded to the roof frame using adhesive, the rigidity of the bond would be significantly reduced, and the plastic roof would no longer be able to contribute to the rigidity of the vehicle body, especially torsional rigidity, as it did in the past! IR<
There is a problem.

防止し得るようにづるものである。The present invention has been made in view of these points, and its [] purpose is that the length of the portion of the plastic roof where the thermal expansion is large is the best in the diagonal direction. row, and based on this t row,
When attaching the Plus Boot Kloof to the metal roof frame of the car body by adhesive bonding, hard adhesives and soft adhesives should be used as appropriate to reduce the torsional rigidity of the car body. This is intended to effectively prevent deformation and damage caused by the difference in thermal expansion between the plus book roof and the roof frame.

成としたものである。(Another Means to Solve the Problem) In order to achieve the above object, the solution of the present invention is to provide a mounting structure in which a plastic roof is glued onto a metal roof frame of a vehicle body. The middle part of the side part is bonded with a hard adhesive, and the corner part of the plastic roof is bonded with a soft adhesive.

ックルーフの変形が有効に抑制されることになる。(Function) With the above configuration, the plastic roof is most likely to undergo thermal expansion in the diagonal direction, and the difference in thermal expansion with the metal roof frame increases, but the periphery of the plastic roof in this direction In other words, the corners of the plastic roof are bonded to the metal roof frame with a soft adhesive, so the above-mentioned difference in thermal expansion is absorbed and alleviated by the elasticity of this adhesive, resulting in the difference in thermal expansion. Deformation of the plus deck roof is effectively suppressed.

The periphery of the plus deck roof other than the corners, that is, the middle part of the side, is bonded to the metal roof frame with a hard adhesive, and the bonding rigidity between the plus deck roof and the roof frame is 1. This ensures that the torsional rigidity of the vehicle body does not deteriorate.

This is shown in Fig. 1.In other words, the middle portions of the four sides of the above-mentioned plus deck roof 7 are each bonded with hard adhesives 8, 8, etc., each having a high V-flag ratio in the bonded state. 6, and the four corners of the plastic roof 7 are bonded with soft adhesives 9, 9, etc., each having a small Young's modulus in the bonded state.As the hard adhesive 8, For example, a two-component urethane resin adhesive is used, and the Young's modulus in the adhesive state is approximately 5 k!

なる。Next, to explain the operation and effect of the above embodiment, when the 18 rectangular plastic roof 7 attached to the metal roof frame 6 of the vehicle body expands thermally, the plastic roof 7 expands in the diagonal direction. Since the length is longer than the length in the longitudinal direction or the width direction of the vehicle body, the largest thermal expansion occurs in the diagonal direction, and the difference in thermal expansion with the metal roof frame 6 is also large in that direction.

づることができる。In this case, the diagonal peripheral edges, that is, the four corners, of the plastic roof 7 are bonded to the metal roof frame 6 with soft adhesive 9, 9°, etc., respectively. , the thermal expansion difference in the diagonal direction is 9.9. ... is absorbed and relaxed by following the plastic roof 7 which undergoes large thermal expansion due to elastic deformation. As a result, deformation of the plus deck roof 7 due to the difference in thermal expansion can be effectively suppressed, and damage near the adhesive joint (periphery) of the plus deck roof 77 can be prevented.

The plus deck roof 7 effectively contributes to the torsional rigidity of the vehicle body and does not cause a decrease in the torsional rigidity of the vehicle body.

It is effective when applied to fairly large cases such as the case between Sujiru and Sujiru.
