  When the operation is started in this state and the temperature of the front lower panel 7 rises, the front lower panel 7 expands and tries to deform so that the warpage of the front lower panel 7 itself becomes straight. The front lower panel 7 cannot be deformed because the claw portion 16 of this is in contact with the middle portion 20 of the front lower panel assembly portion 18, and the front end portion 19 of the front lower panel assembly portion 18 and the end of the decorative band 10 are bent. The bent portion at the end of the decorative band 10 does not run over the front end portion 19 of the front lower panel assembling portion 18, and the bent portion at the end of the decorative band 10 is at the front surface while the gap with the portion remains 0.7mm. It is possible to prevent the tip 19 of the lower panel assembling part 18 from getting on.

  Further, when the operation is stopped from the operation state and the temperature of the front lower panel 7 decreases, the expanded front lower panel 7 shrinks and tries to deform to return to the warpage of the front lower panel 7 itself. The claw portion 16 of the front lower panel body 8 that has pressed the middle part 20 of the front lower panel assembly 18 strongly due to the expansion of the panel 7 returns to the original state, and returns to the contact state before the start of operation. It is.

  As described above, the claw portions 16 are formed at the upper ends of both ends of the front lower panel body 8 so as to be in contact with the middle portion 20 of the front lower panel assembly portion 18, thereby shortening the folding of both ends of the decorative band. The operation starts and the temperature of the lower front panel 7 rises while maintaining the state in which the folded portion of the decorative band and the curved surface portion of the end portion of the lower front panel are in close contact with each other. Even if the panel 7 itself is warped so as to be straightened, the claw portion 16 comes into contact with the middle portion 20 and the bent portion of the end of the decorative band 10 rides on the front end portion 19 of the front lower panel assembly portion 18. It is possible to prevent the generation of sound when riding.

  Further, even if the operation is stopped and the temperature of the front lower panel 7 is lowered and the front lower panel 7 is deformed so as to return to the warped state before the start of heating, the middle part 20 of the front lower panel assembly 18 is strongly pressed. Since the nail | claw part 16 of the front lower panel main body 8 which it had returned returns to the original state and returns to the contact state before a driving | operation start, the bending part of the edge of the decorative band 10 is the front-end | tip part 19 of the front lower panel assembly | attachment part 18. It is possible to prevent the generation of sound when returning from the state where the vehicle is mounted.
