Abstract
A vacuum cleaner includes a vacuum suction pipe through which impurities are collected together with air. A suction side plate has a central hole which corresponds with the vacuum suction pipe so that the vacuum suction pipe is fitted in the central hole. A holding plate is spaced apart from the suction side plate. A spring unit connects the suction side plate with the holding plate to elastically adjust a distance between the suction side plate and the holding plate.
