It is possible to prevent the temporary clip 20 from being accidentally dropped. When temporarily fixed, the position of the fixing screw hole 17 in the fixing piece portion 15 of each support member 2 coincides with the position of the screw insertion space 12 of the frame main plate portion 5 in each of the other pair of lid frame members 3b.

  After the lid frame 3 with the support member is inserted into the square opening S, the frame main plate portion 5 in each of the other pair of the lid frame members 3b facing each other is fixed to the fixing piece portion 15 of each support member 2 through the screw insertion space 12. The fixing screw 11 is inserted into the screw hole 17 and fastened to each other opening edge L facing each other, thereby fixing each support member 2 to each pair of opening edges B facing each other. Thereafter, in order to attach the lid face plate 8, the lid frame 3 is pulled out from the square opening S, the temporary fixing clip 20 is removed, and the fixing screw 11 at the location where the screw insertion space 12 does not correspond is tightened. In the fourth embodiment, each support member 2 has the fixing piece portion 15 and the spring piece portion 19 that are orthogonally connected along the perpendicular plane of the corner of the rectangular opening S. Since the position of the support member 2 can be set and fixed at any position along the surface, the optimal locking position of the spring piece portion 19 with respect to each pair of cover frame members 3a facing the inspection port lid 1 is set. It is possible to secure the optimum position by fixing the fixing piece 15 at the set position.
