PURPOSE: A pipe cleaning device is provided to remove dust or foreign matters from the inside of the pipe efficiently and easily by moving the flexible shaft casing back and forth in the pipe, and to improve working efficiency by calculating the length of the flexible shaft casing and varying the gap of the roller according to the thickness of the flexible shaft casing. CONSTITUTION: A pipe cleaning device comprises a winding part(20) winding a flexible shaft casing(10), a brush(12) formed in the end of a wire cable inserted to the flexible shaft casing, a turning motor integrally rotating the wire cable with the brush, a couple of roller supporting parts(50,50a) formed at the side of the winding part and composed of an upper supporting plate and a lower supporting plate, a feeding roller(30a) rotating in the roller supporting part and feeding the flexible shaft casing, a guide roller placed in the roller supporting part of the feeding roller to guide the flexible shaft casing, an rpm detecting sensor(80) detecting rpm at the side of the feeding roller, a driving unit having a driven gear in the lower part of the feeding roller, a driving gear and a driving motor, and a control unit controlling speed, forward rotation and reverse rotation of the driving unit. The gap with the roller is varied by sliding the roller supporting part along the guide.
