PURPOSE: A suction nozzle for a vacuum cleaner is provided to efficiently clean the corners of a wall surface by easily moving the suction nozzle along the wall surface. CONSTITUTION: Rotary shafts are vertically installed at the front center and both corners of a casing(42). Rollers(46,47,48) are rotatably installed at the rotary shafts, respectively, and partially protrude outside the casing. The rollers are rotated on the rotary shafts so that a suction nozzle(40) easily moves along a wall surface.
