The outer frame with a strip lip formed therein is inserted into the opening formed in the outer wall, and this outer frame is fixed to the outer wall using a fastening tool that has two clamping plates at both ends of the bolt. This is done by simultaneously holding the outer wall and two strips between two holding plates, and
A plurality of hooks are provided on the outer periphery of the outer frame so that the hooks are parallel to the outer surface of the outer frame and their hooks face toward the inner wall and on the inside. The inner frame, which has a convex and convex portion formed thereon and a folded edge that is folded outward at the outer circumference of the inner end and is hooked to the inner surface of the inner wall, is inserted into the opening formed in the inner wall and fixed to the opening in the outer wall. The uneven portion formed on the inner frame is engaged with the hook of the outer frame, and the elastic material provided on the outer circumferential surface of the inner end of the outer frame is pressed against the inner circumferential surface of the outer end of the inner frame. It is designed to ensure that the hook and the concave and convex portions of the inner frame are interlocked.

（作用）フツクと凹凸部の咬合を弾性水蜜材の押圧によ
つて確実にする。(Function) The engagement between the hook and the uneven portion is ensured by the pressure of the elastic material.

An edge portion that is hooked to the outer surface of the outer wall 9 is formed on the outer peripheral portion of the outer end, and two lips 10, 10 are formed on the outer circumferential surface at an interval that is approximately equal to or slightly smaller than the thickness of the outer wall 9.
This outer frame 8 is inserted into an opening formed in the outer wall 9, and is clamped by fasteners 11 having two clamping plates at both ends of the bolt. It is fixed to the outer wall 9. A plurality of hooks 12 are provided on the outer periphery of the outer frame 8, parallel to the outer periphery of the outer frame 8, with their hooks facing toward the inner wall 13 and on the inside. In the figure, reference numeral 14 denotes an inner frame, and an uneven portion 15 for engaging with the hooks 12 is formed on the outer periphery of the outer end thereof. To fix the outer frame 8 and the inner frame 14, first fix the outer frame 8 to the outer wall 9 with fasteners 11 as described above, and then attach the inner frame 14 to the opening of the inner wall 13. 16, and push in the uneven portion 15 of the inner frame 14 until the hooks 12 of the outer frame 8 and the folded edge 17 provided at the inner end of the inner frame 14 come into contact with the inner surface of the inner wall 13. In addition, the inner end of the outer frame 8 is brought into contact with the outer circumferential surface of the outer frame 8, that is, the inner frame 14, so as to be pressed in the direction of waterproofing and opening the outer end of the inner frame 14 (the direction in which the uneven portion 15 and the hooks 12... are more interlocked). The elastic water absorbing material 18 is provided in the portion. Furthermore, it is preferable to provide the honey material 19 on the inner surface of the folded edge 17 of the inner frame 14. FIG. 2 is a perspective view showing the entire outer frame 8 and inner frame 14 described in FIG. 1.
