る（例えば実開昭54−28807号公報）。 By the way, when this vehicle body panel is affected by heat such as direct sunlight, it reaches a considerably high temperature and expands.
In particular, car body panels made of synthetic resin have many advantages over panels made of steel sheets, such as being lighter and easier to manufacture, but on the other hand, because of their high coefficient of thermal expansion, It is prone to thermal distortion and thermal expansion deformation. For this purpose, a mounting structure has been provided in which a synthetic resin panel is fixed via a connecting member that allows the panel to expand and contract due to thermal expansion (for example, see Japanese Utility Model Application Publication No. 54-28807).

フレームにも適用できる。(Effects of the invention) According to this invention, since the elastic deformation portion deforms elastically to absorb the deformation force of the roof panel due to thermal expansion, if the synthetic resin roof panel expands under the influence of heat, In addition, the roof panel that receives this expansion force allows the elastic deformation part to elastically deform according to the force, efficiently avoiding the expansion force, and has a cutout opening along the longitudinal direction of the vehicle body frame. Therefore, it can be applied to any frame, such as a roof header extending in the width direction of the vehicle body or a roof rail extending in the front-rear direction, against expansion and contraction of the roof panel due to heat.
したがつて、ルーフパネルには熱歪や熱変形が
発生することがなくなり、常に適正なパネル形状
を維持することができる。 Therefore, thermal distortion and thermal deformation do not occur in the roof panel, and an appropriate panel shape can always be maintained.
また、弾性変形部を直接車体フレームに形成し
ているので、ルーフパネルの取付けに際しては、
結合部材の位置決め調整を要しないため、簡単に
取付けることができる。 In addition, since the elastic deformation part is formed directly on the vehicle frame, when installing the roof panel,
Since no positioning adjustment of the connecting member is required, installation is easy.

持される。 Even if the roof panel 11 itself expands due to the influence of heat such as direct sunlight, the roof panel of the automobile attached in this way will be able to maintain its elasticity to accommodate the expansion force. As shown by the imaginary line in FIG.
The deformation force at the time of one expansion is absorbed, thereby reliably eliminating the deformation phenomenon of the roof panel 11. For this reason, the roof panel 11 is not subjected to thermal distortion, etc., and the panel shape in its initial state with excellent aesthetic appearance is always maintained.

The elastic deformation part 44, which is made up of a circular notched groove 43 cut out to surround the bolt insertion hole 42 in a semicircular shape, also releases the restraint from the structure on the bolt insertion hole 42, causing thermal deformation force. It is given the elastic force that should be absorbed, and exhibits the required elastic deformation function.
