HOSE FOR VACUUM CLEANER

摘要

PROBLEM TO BE SOLVED: To provide a hose for a vacuum cleaner with fine flexibility and tensile-resistant force and which is made of a soft synthetic resin that has no possibility to generate delamination in a tube wall even if the hose is bent. SOLUTION: A hollow spiral projecting strip 2 in which a metallic line for conducting 3 is installed at the outer peripheral face of an inner layer pipe 1 made of a soft synthetic resin is fixed unitedly and an outer layer pipe 6 which is made of a soft synthetic resin is fixed at the whole face of the periphery of the inner layer pipe 1 including the hollow spiral projecting stripe 2. Then, plural number of first reinforcing wires 4 which imparts tensile-resistant force so as to be paralleled with longitudinal direction to the hose are provided at the outer peripheral face of the inner layer pipe 1 and the first reinforcing wires 4 are pressed to the inner layer pipe 1 by second reinforcing wires 5 which are fixed by being spirally wound around the middle of the peripheral face between the hollow spiral projection stripe part 2, 2.
