ある。In Fig. 2, (10) is the sheet of the cover (2), (1 is the surface side (outside) of the sheet with a weather-resistant elastic material such as rubber, and (12) is the back side (inside) of the sheet (the spacer). ) is an elastic material filled with reinforcing fabric such as nylon, and (13) is an air chamber between the elastic material (1) of the sheet and the elastic material filled with reinforcing fabric (12) (when air is introduced, it swells as shown in Figure (b)). Ruru.In Figure 2, the figure (al) is normal (when no gas is introduced into the air chamber),
Figure (b) is an example of snow removal (when gas is introduced into the air chamber).
