Patent ID: 7159276

Claim:
A rotary cleaning body comprising: a cylindrical mounting meter which is formed of a deformable material and has a cylindrical outer surface, and which comprises: (i) a plurality of recessed receiving grooves in the outer cylindrical surface that are spaced apart circumferentially around the mounting meter and that extend axially along the mounting meter, and (ii) a plurality of recessed stopper grooves that are formed in the outer cylindrical surface of the mounting member between adjacent ones of the receiving grooves; a plurality of cleaning members, each of which has a base end secured in a corresponding one of the receiving grooves to be attached to the mounting member so as to extend along the axial direction of the mounting meter and protrude outward in a radial direction of the mounting meter; an axial member inserted through a center of said mounting member; a plurality of supporting meters which prevent unintentional displacement of the cleaning meters at axial ends of the receiving grooves, and each of which comprises a plurality of fitting protrusions that are insertable into the stopper grooves, respectively, so as to secure the mounting member to the axial member; and wherein when the supporting members are coupled to the axial member, the coupling of the supporting members to the mounting member via the fitting protrusions and stopper grooves causes the mounting member to be spirally twisted such that the receiving grooves are shaped into spirals, and the mounting member is supported in the twisted state due to the coupling of the supporting members to the mounting member via the fitting protrusions and stopper grooves.
