<p><P>PROBLEM TO BE SOLVED: To completely prevent water leakage in a cabinet while establishing combination between slidability and bendability by using a simple structure. <P>SOLUTION: A hose body 1 is bendably formed of a flexible material, and many rigid rings 2, which are composed of a protrusion 2a annularly protruding in a radial direction, are protrusively provided at each proper interval in the axial direction of a hose, on the outer peripheral surface 1a of the hose body 1. The rigid rings 2 are arranged in such a manner that the interval between the rigid rings 2 has such a dimension that a hose-swollen part 1b, swollen and deformed along with the bending of the hose body 1, is not protruded from a leading end 2a' of the protrusion 2a. Thus, a bending ratio is high because the whole hose H is bent only by bending the hose body 1; since only the leading end 2a' of the protrusion 2a of each rigid ring 2 comes into contact with a hose passage C3, an area of the contact between both of them is very small; and water is prevented from intruding into the hose body 1, even if the whole extracted hose is soaked in the water. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
