The present invention is related to a suction pipe of a vacuum cleaner which permits arbitrary stretching and control of the length of the suction pipe which is combined with a vacuum cleaner. The suction pipe of results in a more compact and stable operational structure whose length can be controlled arbitrarily. An outer pipe is drawn from an inner pipe by sliders elastically combined to the outer side of the outer pipe in the longitudinal direction. The movement of the sliders in any one direction detaches stoppers from respective control homes of the inner pipe. The stoppers are combined with their control homes when the sliders are returned to their original locations.
