PROBLEM TO BE SOLVED: To provide a strong and inexpensive rotating roll brush, suitably diverting a keyed shaft for forming a disk type rotating roll brush to a shaft of a channel type rotating roll brush. SOLUTION: In this rotating roll brush, flanges 12, 13 are integrally fitted in both end openings of a cavity 10' of a coil brush 10 formed of a channel brush 7, the coil brush 10 is externally fitted to a shaft 11 to fit the shaft 11 to the inner peripheral surfaces of the flanges 12, 13 at both ends, and a projection key 11a of the shaft 11 is key-connected to a recess key 16 formed in the inner peripheral edges of both end flanges 12, 13. A bar 17 is extended between both end flanges 12, 13, the inner surface 17a of the bar 17 is superposed and supported on the projection key 11a of the shaft 11, and an intermediate flange 20 fitted between both end flanges 12, 13 of the coil brush 10 is supported on the outer surface 11b of the bar 11.
