The filter member F is suspended in the leg pieces 13b in the lid member 13 so as to be inserted into the inside from the opening arranged on the upper face of a case main body 15, and the lid member 13 is pushed down so as to rotate the link pieces 14, and then, the filter element 11 is advanced with the frame body 12 by means of the link pieces 14, so that the packing material is brought into pressure contact with the wall face of the case main body 15, and consequently, tight sealing is accomplished. |
