<p><P>PROBLEM TO BE SOLVED: To provide a vacuum cleaner hose in which used amount of an electric wire is drastically reduced by eliminating an overcrowding structure of the electric wire, the issue of conventional vacuum cleaner hose, to drastically reduce the manufacturing cost of the hose lightened but more flexible. <P>SOLUTION: This vacuum cleaner hose is formed by spirally winding and sticking a band-shaped material having hollow protrusions connected to each other in a line. The hose 1 is formed of one row of the band-shaped material 2 in which the hollow protrusions 4a are classified into hollow protrusions 4 inserted with the electric wire 5 from hollow protrusions 4a inserted with no electric wires 5, or the hose is formed of two rows of the band-shaped materials 2, 2 in which only one row of band-shaped material 2 is inserted with the electric wire 5, or the electric wire 5 is separately inserted into two band-shaped materials 2, 2 so that a required amount of the electric wire 5 to be inserted into the hose 1 is reduced by the hollow protrusions 4a inserted with no electric wires 5. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
