PROBLEM TO BE SOLVED: To provide a suction hose of a vacuum cleaner, which solves the following inconveniences that a conventional suction hose of the electric cleaner has a rugged inner wall and therefore dust adheres to or engages with the same, to thereby hinder dust from smoothly passing through the hose to be sucked into a cleaner main body, and that the conventional suction hose is insanitary because ticks and bacteria can grow in the hose and a child can attach his/her mouth to a suction port of the suction hose by playing a prank. SOLUTION: There is provided a new suction hose of the vacuum cleaner, which has an inner wall with no rugged portion. COPYRIGHT: (C)2004,JPO&NCIPI
