PURPOSE:To suppress the deformation of a plastic roof which is caused by the difference of thermal expansion by allowing the intermediate parts of four side parts of the plastic roof to adhere by the use of the hard adhesive and allowing four corner parts to adhere by the use of the soft adhesive. CONSTITUTION:The intermediate parts of four side parts of a plastic roof 7 are allowed to adhere by the hard adhesive 8 having a large Young's modulus in the adhesion state. Further, four corner parts of the plastic roof 7 are allowed to adhere by the soft adhesive 9 having a small Young's modulus in adhesion state. |
