Abstract

PROBLEM TO BE SOLVED: To facilitate and ensure mutual connections by arranging an external convex part toward the inside of a box on the inner periphery side of a duct connecting port and forming an internal convex part for abutting thereon. SOLUTION: With an external convex part 37 on the flexible duct side being set to the position of a concave part 28 on the box side, an inner extension tube for connection 36 is inserted into a protruding body 23 until the external convex part 37 reaches the inside of the box beyond an internal convex part 25. Then, the inner extension tube for connection 36 is rotated by a specified amount around a tube axis, and the external convex part 37 is abutted on the internal convex part 25 toward the inside of the box. As a result, unless the inner extension tube for connection 36 is rotated further, the flexible duct will not come off from the box. And, by fixing a packing 35 as in the case of the foregoing, a connecting structure in a stable and rigid condition is obtained easily.
