Abstract
A cleaning rotary brush 1 comprises a hard base 3 mounted to a rotary shaft and a plurality of ridged projections 27 formed on and projecting from the working surface of the base 3, the tops of said ridged projections 27 in contact with an object to be cleaned while rotating in substantially the same plane. The ridged projections 27 are made of a polyvinyl acetal porous elastomer and disposed continually on a plurality of phantom setting lines 31 extending from inner reference, points 31a on the side of the center of rotation 35 of the working surface to outer reference points 31b on the side of the outer periphery 17b of the working surface. The length L1 in a longitudinal direction of said ridged projections 27 is made longer than the length D1 in a widthwise direction of the ridged projections 27. Thus, the spent cleaning liquid containing dirt or particles scrubbed from the portion to be cleaned is guided by the ridged projections 27, led adequately to outer reference points 31b, and rapidly drained off to the outside of the system.
