A latching member that can be A holding member that is a cylindrical body formed of a plate material, the upper part having a divergent part and a horizontal part that extends horizontally outward from the upper part, and capable of holding the upper part of the hooking member with the base member; The holding member and the foundation are formed in a rectangular plate shape having an opening larger in diameter than the upper end opening of the end-spreading portion of the holding member, and placed on the holding member so that the opening is substantially concentric with the holding member. A filter cloth partition provided with a retainer, comprising: a pressing member that presses each horizontal portion of the member; and a fastening means that is attached to the partition plate and fastens the base member and the clamping member with the pressing member. There are excellent practical effects such as easy and reliable attachment to the plate in the vertical state possible.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. As shown in FIG. 1, the retainer suspends a filter cloth 4 with a retainer 3 suspended in a through hole 2 of a partition plate 1 that is horizontally stretched in a dust collector cabinet (not shown). The installation device is a short cylindrical body having a body formed of a plate material, and can be placed on the partition plate 1 so as to be substantially concentric with the through-hole 2, and the upper body 5 is bent inward and extends horizontally. A base member 7 having an opening 6 through which the retainer 3 can penetrate, and a base body 7 having a central body formed of a plate material; and an upper end of the retainer 3. The body is fixed substantially concentrically to the body, and the upper body 8 has a divergent shape and is formed to correspond to the inverted head-shaped spherical portion of the base member 7 and can be hooked substantially in accordance with this. And the lower part has a smaller diameter than the opening 6 of the base member 7 A hook member 9; and a body having a cylindrical body formed of a plate material. The body has a divergent part 10 at its upper part and a horizontal part 11 extending horizontally outward from the upper part, and the divergent part 10 is The hooking member 9 and the base member 7 can be hooked to the inverted head-cut spherical portion, the outer diameter of the lower part is shorter than the inner diameter of the retainer 3, and the divergent portion 10 is the hooking portion. A clamping member 12 capable of clamping the upper portion of the member 9 with the inverted truncated spherical portion of the base member 7; a rectangular shape having an opening 13 having a diameter larger than that of the upper end opening of the divergent portion 10 of the clamping member 12; A pressing member 14 that forms a plate shape and is placed on the clamping member 12 so that the opening 13 is substantially concentric with the clamping member 12 and presses the horizontal portions of the clamping member 12 and the base member 5; The above Riita are constituted by this and is attached to the 1 and bolts and nuts 15, 16 as clamping means tightening the horizontal portion 11 of the pressing member 12.

The pressing member 12 is configured such that the peripheral portion of the horizontal portion 11 is bent downward and the upper portion is loosely fitted to the base member 7.

Next, a procedure for hanging a filter cloth 4 having a retainer 3 in the through hole 2 of the partition plate 1 will be described. First, after the filter cloth 4 having the retainer 3 provided therein is passed through the through-hole 2, the end-spreading portion 8 of the hooking member 9 is temporarily placed on the upper portion 5 of the base member 7 that forms the inverted head-cut spherical shape. Subsequently, the retainer 3 is swung in three dimensions with the contact point of the base member 7 and the latching member 9 as a fulcrum, and the end-expanded portion 8 of the retainer 3 is turned upside down. Familiarize with the spherical upper part 5. As a result, the retainer 3 and the filter cloth 4 are respectively hooked on the base member 7 and the partition plate 1 and hung in a substantially vertical shape by its own weight. Next, the sandwiching member 12 is placed on the upper portion 5 of the base member 7 while being suspended vertically and is loosely fitted, and then the pressing member 14 is placed on the sandwiching member 12 so as to be substantially concentric with the sandwiching member 12. Then, the bolts 15 and 15 are penetrated. Thereafter, the nuts 16 and 16 are screwed onto the bolts 15 and 15 to fasten the pressing member 14 and fix the retainer 3 to the partition plate 1.

In the above-described embodiment, the portion 5 bent inside the base member 7 and the end-spreading portion 10 of the hooking member 9 form an inverted truncated spherical shape, but are not limited thereto. Of course, for example, the same effect can be obtained even when the inverted conical shape is used.
