  The cover member 36 is fixed to the upper portion of the outer peripheral foundation 6 by sandwiching the airtight member 48 and the third cover 42 between the outer peripheral foundation 6 and the base 16. Of the cover member 36, the first cover 38 and the second cover 40 are continuous in a crank shape, and the second cover 40 presses the upper end portion of the inner heat insulating material 30 against the outer peripheral foundation 6.

  In the basic heat insulating structure of the present embodiment, a decorative cover 50 is provided to cover the outer heat insulating material 28 mounted on the outdoor side of the outer peripheral foundation 6.

  The decorative cover 50 is a nonflammable cover made of metal. The decorative cover 50 covers the entire surface of the outer heat insulating material 28 except for the surface facing the outer peripheral foundation 6. The decorative cover 50 preferably has a pattern or color coordinated with the exterior material 26 on the building 2 side.

  Furthermore, the basic heat insulating structure of the present embodiment includes a draining member 52 that is attached to the upper part on the outdoor side of the outer peripheral foundation 6.

  The draining member 52 includes a fixed piece 54 that is fixed to the surface of the base 16 on the outdoor side, and a draining piece 56 that extends from the lower end of the fixed piece 54.

  The draining piece 56 has a bent portion at an intermediate portion thereof. The draining piece 56 is fixed to the base 16 so that a half part above the bent part becomes an inclined piece 58 and a half part below the bent part becomes a hanging piece 60.

  The inclined piece 58 is an inclined piece so as to be positioned on the outdoor side as it goes downward. The suspended piece 60 is suspended from the lower end of the inclined piece 58 in the vertical direction.

  The hanging piece 60 is provided so as to press against the upper end portion of the outer heat insulating material 28 from the outdoor side. In the present embodiment, the drooping piece 60 presses against the outer heat insulating material 28 via the decorative cover 50.
