Further, since the heat insulating body 14 is attached to the outer peripheral side surface 12a of the frame body 12 so that the ribs 12b of the left and right outer peripheral side surfaces 12a of the frame body 12 are exposed, the frame body 11 is attached to the opening 2 of the foundation 1 and then the frame body. It is possible to improve the adhesion with the foamed synthetic resin 5 filled in the gap between the 11 and the opening 2.

The lid 21 is made of a foamed synthetic resin (for example, Styrofoam) and has heat insulating properties. Further, as shown in FIGS. 1 to 3, the lid body 21 is formed in a substantially square plate shape that can be fitted into the opening 15. As shown in FIG. 6A, the lid body 21 has two convex portions (first engaged portions) 22 protruding downward from the lower surface 21a. These two convex portions 22 are formed in a shape and position in which the lid 21 is fitted and engaged with the two concave portions 17 when the lid 21 is arranged in the opening 15. That is, the two convex portions 22 are also arranged apart from each other along the longitudinal direction A.

As shown in FIGS. 1 to 3, the lid body 21 has a grip portion 23 protruding from the outer surface 21c exposed to the outside when the lid body 21 is attached to the frame body 11. As shown in FIG. 6A, the grip portion 23 is arranged slightly below the upper end of the lid 21 and in the center of the longitudinal direction A, and extends along the longitudinal direction A.

At the upper end of the lid 21, the two convex portions 22 of the lid 21 are fitted into the two recesses 17, and the upper end of the lid 21 is pushed inward along the width direction B to form a frame. A lock member 25 is provided to engage with the convex portion 18 of the body 11 to lock the lid 21. The lock member 25 is made of synthetic resin and is arranged at the center of the lid 21 in the longitudinal direction A. The lock member 25 includes a mounting portion 26 attached to the upper end portion of the lid 21, an elastic support portion 27 bent and extending from the mounting portion 26, and a convex portion formed at the tip of a corner portion of the elastic support portion 27. It has (second engaged portion) 28.

As shown in FIG. 6A, the elastic support portion 27 extends outward from the mounting portion 26 along the width direction B above the grip portion 23, then bends downward once, and then moves in the width direction B. It is formed so as to extend outward along the line. The convex portion 28 is formed so as to extend along the longitudinal direction A at the upper end of the corner portion of the portion that bends downward of the elastic support portion 27.

When the opening 15 is closed by such a lid 21, the two convex portions 22 of the lid 21 are fitted into the two concave portions 17, and the upper end portion of the lid 21 is inside along the width direction B. When the convex portion 28 is pushed toward the surface, the elastic support portion 27 is once bent downward so that the convex portion 28 gets over the convex portion 18, and then returns. That is, the elastic support portion 27 can be elastically deformed so as to engage the convex portion 28 with the convex portion 18. As a result, the convex portion 28 and the convex portion 18 are engaged with each other, and the lid body 21 is locked to the frame body 11. At this time, since the frame body 11 has two concave portions 17 and one convex portion 18, and the lid body 21 has two convex portions 22 and one convex portion 28, the lid body 21 has an opening of the frame body 11. It can be attached by engaging with 15 at three points. Therefore, the lid 21 can be fixed to the frame 11 without rattling, and the airtightness between the frame 11 and the lid 21 is improved. On the other hand, when the tip 27a of the elastic support portion 27 is pressed downward so as to approach the grip portion 23 while the lid body 21 is locked to the frame body 11, the engagement between the convex portion 28 and the convex portion 18 is released. The elastic support portion 27 bends downward, and the convex portion 28 moves downward. Then, the lid body 21 is framed by gripping the grip portion 23 in a state where the convex portion 28 and the convex portion 18 are disengaged and pulling the upper end portion of the lid body 21 outward along the width direction B. It can be removed from the body 21.
