PROBLEM TO BE SOLVED: To effectively discharge hair-like dust and powdery dust brushed off and taken inside. SOLUTION: A corner brush 22 is fixed on an external support member 33, where a base cloth 41 is adhered to the peripheral surface of a protruding part 48 of the external support member 33, with the edge of the base cloth 41 inserted into a circular groove 49 of the external support member 33, Then, an internal support member 32 is fitted onto the external support member 33, pressing brush bristles 42 at their roots 51 so tightly that the root part has a higher density than the brush end part. This makes hairs caught by the brush bristles 42 less likely to move up toward the center, and prevents them from easily getting entangled with the root part of the brush bristles 42. Furthermore, a radial and outward air flow is generated by six blades 52 provided on the inner support member 32 and four blades 47 provided on the front part of the external support member 33, in order to blow off the hairs that are otherwise almost getting entangled with the root part of the brush bristles 42.
