PROBLEM TO BE SOLVED: To provide a vacuum cleaner which prevents a surface of its electrostatically flocked wheel from being entwined with lint, hair, and the like, and has an intake part whose running noise is reduced even on a boarded floor. SOLUTION: A front wheel 14 which rotates back and forth by an axle 13 fixed in a case 2 below the intake part 1 as a running support means is applied on both edges of a front end of the bottom surface of the case 2, and a rear wheel 16 which also rotates back and forth by a rotation shaft 15 as a running support is applied so as to be positioned in the middle in width direction of a rear end. The rear wheel 16 comprises a wheel part 17 and a body part 18 on whose surface bristles 19 are electrostatically flocked. The bristles 19 are smoothed by heat treatment after flocked electrostatically. Therefore, the purposes are attained, such as improvement in its operation when moving the intake part 1 back and forth, right and left, reduction of its tumbling noise on the boarded floor, and prevention of scratch on the floor. Moreover, the wheel is designed to prevent its surface from being entwined with lint, hair, dust, and the like. COPYRIGHT: (C)2004,JPO&NCIPI
