When a line inclined with respect to one imaginary line is used as the second imaginary line, the second imaginary line is inclined with respect to the central axis, and the sponge body and the spacer are alternately mounted on the shaft body. Is attached to the shaft body obliquely by the center hole, and the sponge body is supported by the spacer and attached to the shaft body obliquely.

  In the sponge roll of the present invention, the sponge body includes a plurality of convex pieces protruding from the outer periphery.

  According to the present invention, for example, when the surface of an object to be cleaned such as a glass substrate is cleaned with cleaning water or the like, dust or the like separated from the object to be cleaned can be poured into the sponge bodies, that is, into the gap. Thereby, dust etc. can be prevented from remaining on the surface of the sponge roll. That is, the sponge roll of the present embodiment has a self-cleaning function, so that the clean state of the surface of the sponge roll that is always in contact with the object to be cleaned can be maintained. Moreover, since the sponge body adjacent to the gap is set obliquely with respect to the shaft body, generation of brush marks on the surface of the object to be cleaned such as a glass substrate can be prevented.
