When screwed into the pair of filtration floor plates 1c, 1c, the pair of filtration floor plates 1c, 1c are made to face each other via the elastic sheet 3. By doing so, the pair of filtration floor plates 1c, 1c can be more sufficiently tightened by the connecting protrusions 2, and the impact force acting on the filtration floor plates 1c can be absorbed by the elastic sheet 3, so that each filtration is performed. The thickness of the floor board 1c can be made thin. Further, by sandwiching the elastic sheet 3 between the pair of filtration floor plates 1c, 1c, the tightening force of the pair of filtration floor plates 1c, 1c can be adjusted. The elastic sheet 3 is preferably about 3 to 5 mm, for example. The elastic sheet 3 may be in contact with the entire back surface of the filtration floor plate 1c, or may be in contact with only the vicinity of the connecting protrusion 2. Further, as shown in FIG. 5, taking into consideration the thickness of the filter floor plate 1c and the size of the connecting protrusions 2, an annular screw seat 1m is formed around the screw hole 1k of the filter floor plate 1c to reinforce. You may Further, the screw seat 1k is not limited to the one integrally formed with the filtration floor plate 1c, and instead of the screw seat 3, an annular member or a strip plate member is provided separately from the filtration floor plate 1c, and the filtration floor plate 1c is provided. You may make it attach to 1c.
