Title:
Brush roller
Document Type and Number:
Japanese Patent JP6163081
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce a decrease tendency of an elastic force of a brush roller with the lapse of use time thereby stabilizing an efficiency of washing during a long time.SOLUTION: A brush roller 1 is configured from a PVAt-based porous raw material, and has a substantially cylindrical-shaped roll body 3 and plural projections 5. The plural projections 5 integrally project from an outer peripheral surface 12 of the roll body 3 to an apex 5a. The roll body 3 is fixedly supported to a rotary shaft 2 in the shaft fitting state such that the rotary shaft 2 is inserted in an inner diameter part of the roll body 3. The projection 5 is brought into rotational contact with a cleaned surface 11 of a flat tabular cleaned body 10 having a thin wall, thereby cleaning the cleaned surface 11. In the shaft fitting state such that the rotary shaft 2 is inserted in the inner diameter part of the roll body 3, a maximum thickness D of the brush roller 1, which is a distance from an outer periphery 2a of the rotary shaft 2 to the apex 5a of the projection 5, is equal to 45% or more of a maximum radius Rb of the brush roller 1 which is a distance from a center S of rotation of the rotary shaft 2 to the apex 5a of the projection 5.
