To provide a rotary brush for a road sweeper, and a road sweeper, in which the rotary brush need not be removed with a rotation shaft from the road sweeper even when brush members are abraded.

The brush members 2 are fixed by a screw 5 through a presser plate 80 at eight positions in the circumferential direction of a cylindrical shaft member 4 in such a way as to be deflected from each other along the length of the shaft member 4 by specified length in a zigzag way to be fixed along the whole shaft member 4 to form a main brush 1. Since the brush members 2 are fastened by the screw, the brush member 2 can be removed by removing the screw 5 as the shaft member 4 is installed on a bearing on the road sweeper.
