のである。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drainage hose according to the present invention will be described below in more detail with reference to an embodiment shown in the drawings. In FIG. 1, reference numeral 1 denotes a hose, which is made of a soft synthetic resin material such as polyethylene or polypropylene, which is a dechlorinated material, and is integrally formed into a desired length (80 to 90 cm) by a blow molding method. Things. An opening at one end of the hose main body 1 forms a joint 2 having a diameter that can be inserted into a drain (not shown) of a drain trap on the sink side, and a length inserted from the joint 2 into the drain. The flange 4 to which the flat packing 3 can be attached is formed.
In addition, a cap nut 5 made of a hard synthetic resin is inserted from the opening at the other end of the hose main body 1 so that the joint 2 can be screwed to the drain port in a watertight manner. In addition, flexibility is imparted by forming a spiral or annular bellows 6 in which thick portions and thin portions are alternately continuous over substantially the entire length of the hose main body 1.
