Abstract
Official abstract text for this publication.
A resin member capable of inhibiting generation of particles due to repeated bending thereof is provided. A rolling diaphragm 5 composed of a resin member has one surface formed as a liquid contact surface 37 a , repeatedly bends when used, and has flexibility. A surface roughness of the liquid contact surface 37 a at a portion 371 that bends is less than 0.40 μm as an arithmetic average roughness, and a total light reflectance of the liquid contact surface 37 a at the portion 371 that bends is not less than 2.0%.
First claim
Opening claim text (preview).
The invention claimed is: 1. A resin member having one surface formed as a liquid contact surface, the resin member repeatedly bending when used, the resin member having flexibility, wherein the resin member is a diaphragm for a pump, the diaphragm having: a surface roughness of the liquid contact surface at a portion that bends is less than 0.40 μm as an arithmetic average roughness, a total light reflectance of the liquid contact surface at the portion that bends is not less than 2.0%, a cross-sectional shape of the liquid contact surface at the portion that bends is a shape in which recesses and projections are alternately continuous, the recesses are formed by concave curved surfaces, wherein the recesses have no flat surface at a bottom of the concave curved surfaces, and ends of the projections are formed as sharp ends, wherein the projections have no flat surfaces at an end of the sharp ends.
