PROBLEM TO BE SOLVED: To provide an inspection port device enabling a frame member to be stably installed on wall materials with different thickness.SOLUTION: An inspection port device according to this invention comprises: a frame member, which is disposed along a circumference of an inspection port formed on a wall material that divides between an indoor space and a space behind a wall; a tabular cover member, which is installed so as to block an opening of the frame member; and a clamp part on the reverse side of the wall, which is engageably and disengageably installed to the frame member. The frame member comprises: an engaged part on the reverse side of the wall, which is formed on the space side behind the wall of the frame member; and a wall material contact part, which is formed on the indoor space side of the frame member and sandwiches the wall material between the wall material contact part and the clamp part on the reverse side of the wall. The clamp part on the reverse side of the wall comprises: an engaging part on the reverse side of the wall, which engageably and disengageably engages with the engaged part on the reverse side of the wall; and a clamp body part on the reverse side of the wall, which is disposed so as to face the wall material contact part across the wall material in a state where the engaging part on the reverse side of the wall engages with the engaged part on the reverse side of the wall. A spacer is disposed between the wall material on the circumference of the inspection port and the clamp body part on the reverse side of the wall.SELECTED DRAWING: Figure 2 |
