After bending e, a spatial notch 11g is formed. Since the cutout portion 11g is larger than the width of the claw portion 4a of the retaining member 4, when the flange portion 11c is rotated and the cutout portion 11g and the claw portion 4a are overlapped with each other, the claw portion 4a and the flange portion 4a are overlapped. The engagement with the portion 11c is released. Therefore, when the flexible duct 10 is pulled, the connecting member 11 can be easily pulled out together. Therefore, it is extremely easy to remove the flexible duct from the chamber body. In this embodiment, the structure in which the flange portion is provided at the end of the flexible duct to connect to the connecting short pipe has been shown, but the flexible duct is directly connected to the connecting short pipe, and the connecting portion is fixed with tape or the like. You can also Further, although the packing is configured to be fitted in the concave groove of the connecting short pipe, the packing may be directly attached to the outer periphery of the connecting short pipe without providing the concave groove.
