The frame member comprises: a first side member, which extends along one side of the circumference of the inspection port; a second side member, which extends along the other side of the circumference of the inspection port and intersects with the first side member at a predetermined angle; and a corner connection member, which is disposed at a joint part of the first side member and the second side member in order to connect the first side member and the second side member with each other. The first and second side members have side walls that are disposed so as to face to each other on the circumference of the inspection port. An engaged part is formed on an end of the side wall on the wall back space side. The corner connection member has an engaging part that engages with the engaged part.SELECTED DRAWING: Figure 2 |
