Abstract (en)
A cleaning sponge roller of PVAt is provided, which has improved durability without damaging cleaning performance. The roller is composed of a porous polyvinylacetal material which is elastic in a wet state, comprising a generally cylindrical roller body 3 and a plurality of projections 5 formed integrally on an outer peripheral surface 3a of said roller body for cleaning an object to be cleaned by having tops 5a of the projections 5 rotate in contact with a surface of the object. Each of said projections 5 comprises a tapering projection base portion 11 extending from the outer peripheral surface 3a of the roller body 3 and a projection end portion 13 having substantially the same cross sectional shape from a top end 11b of the projection base portion 11 to the top 5a of the projection. <IMAGE>
