The periphery (four sides) of the heat insulating material 3 is elastically deformed when the heat insulating material 3 is fitted into the shaft assembly, and has a blade shape as an elastic deformation portion for sealing a gap with the shaft assembly. A flexure (adjuster mechanism) 10 is provided. The flexible piece 10
The heat insulating material 3 itself is formed by forming a slit 11 at the time of molding. The slit 11 has a depth in the thickness direction of the heat insulating material 3 and is formed inside the outermost peripheral edge of the heat insulating material 3 from the outdoor side to the outdoor side along the outermost peripheral edge. A flexible piece 10 as an elastically deformable portion is formed on the outer side of the. Therefore, the flexible piece 10 can flex freely by the amount of the slit 11.
