Abstract
A brush head of a vacuum cleaner can pivot in a horizontal direction as well as a vertical direction with respect to a suction pipe, so as to easily clean an area narrower than the width of the brush head. The brush head of a vacuum cleaner includes a body which is detachably coupled to a suction pipe and is formed with a suction hole for sucking dust. A hollow cylindrical pivoting part is integrally formed with the body at a rear central portion of the body and is formed with a roller receiving cut along a periphery of the lower surface of the pivoting part. A cylindrical pivot supporting member is inserted into the pivoting part to support a horizontal pivoting movement of the pivoting part. The pivot supporting member is formed with a communicating space at its peripheral wall which communicates with the suction hole and the suction pipe, and is provided with a roller at its rear bottom surface. And, a pair of elastic bands are mounted to support the connection between the pivoting part and the pivot supporting member. One end of each elastic band is caught on the pivot supporting member and the other end of each elastic band is caught on the body. The elastic bands are disposed symmetrically on both sides of the body.
