A vacuum cleaner wherein a hose, a pipe and suction nozzle, which are connected to a vacuum cleaner main body incorporating therein a motor fan, are formed with a suction air passage as well as an exhaust air passage for making air exhausted from the motor fan circumfluently flow. The pipe is composed of an inner cylindrical portion having a substantially circular section and forming the suction air passage, and an outer cylindrical portion a part of which is uniformly formed with the inner cylindrical portion and which covers the inner cylindrical portion to form the exhaust air passage. There can be achieved for a light-weighted and slim-sized arrangement of the pipe through which the suction air passage and the exhaust air passage extends without the fear of dust plugging, and a vacuum cleaner of exhaust circumfluently flowing type can be easily put into to practice. <IMAGE> |
