It is made of synthetic resin such as polypropylene or nylon, and is made of the same synthetic resin as the lower case body 1 which has an open upper end and has an outlet pipe 1a at the center of the bottom wall, and has an inlet pipe 2a on one side. The upper case body 2 in the shape of a rectangular dish is provided, and a filter element e, in which a filter material such as filter paper or nonwoven fabric is corrugated and a sealing material S is attached to the upper peripheral edge, is mounted on the intermediate step portion of the lower case body 1. The upper case body 2 is placed on the upper case body 2, and the upper case body 2 is attached to a plurality of peripheral portions (usually 4 places) of the lower case body 1 by a metal clip member 3 such as a steel plate or a copper plate. It is designed to be detachably fastened.

7 and 8 show the clip member 3 described above.
And a box-shaped holder portion 4 that bulges outward and is open at the top and bottom is formed at a plurality of locations around the open end of the lower case body 1, and a right-angled triangle is formed inside the box-shaped holder portion 4. A vertically oriented partition 4b for guiding is provided along the side of the case body 1 along the height thereof, and horizontal pieces 4c orthogonal to this are provided on both sides, and the bottom is divided by the partition 4b. One window hole 4d and a shelf portion 4e that travels inward from the outer wall 4a are provided. On the other hand, the clip member 3 is made of a strip plate that is slightly thinner than the inner width of the box-shaped holder portion 4 and has an arcuate body. The portion 3a and a linear portion 3b bent from one end (lower end in the figure) of the main body portion 3a in a substantially radius direction of curvature, a hook portion 3c inverted from the front end portion to the main body portion and the other end (upper end). Bent in the radius of curvature and bent in the opposite direction at Is formed by the hook 3d, slightly wider cut-split 3e the partition piece 4b is provided from the linear portion 3b of the one end toward the hook portion 3c.

The clip member 3 is inserted in such a manner that the bifurcated hook portion 3c at the tip end is inserted from the lower side of the holder portion 4 through the window hole 4d so as to sandwich the partition 4b, and is assembled in the two-dot chain line state of FIG. When the upper case body 2 is covered on the lower case body 1, the clip member 3 is erected in a solid line state, and the bent base end portion is hooked on the open end step portion of the upper case body 2.

When the clip member 3 is removed from the step of the upper case body 2, the clip member 3 goes from the solid line position to the middle one-dot chain line position to the two-dot chain line position where the linear portion 3b contacts the wall surface of the lower case body 1. In the above-described conventional clip member attaching device, since the holder portion 4 on the case body side does not have a means for restricting the rotation of the clip member 3, the clip member 3 is removed, and the handle portion is rotated. Three
If an excessive force is applied to d or an external force is applied to the clip member 3 in the free state, the clip member 3 will rotate below the lower limit position as indicated by the dotted line in FIG. When the angle θ between 3a and the linear portion 3b at one end is deformed so as to open, and the clip member 3 is erected in this state and the case bodies 1 and 2 are fastened again, the angle θ becomes large. By this, the clip member 3
, The hook portion 3c faces upward at the tightening position, and the hook portion 3c does not make surface contact with the horizontal piece 4c, and the normal fastening function for the case body is lost.
Moreover, the clip member 3 may fall off the holder portion 4 during the rotation.

Therefore, an object of the present invention is to provide a mounting device which prevents the clip member from being deformed, maintains a normal fastening function even when it is used for a long period of time, and is not likely to fall off.
