Abstract
A member having a sliding contact surface that exerts a reduced frictional force when making sliding contact with a prescribed member and retains the lubricating oil more uniformly is provided. The sliding contact surface is a honed surface having flat plateau parts and groove parts. As calculated in regard to the sliding contact surface by using a mean line derived from a cross-sectional curve of the sliding contact surface in accordance with ISO 13565-1, a ten-point average roughness is 0.6-7.0 μm, a load length ratio at a cut level of 20% is 60-98%, an effective load roughness is 0-1 μm, and a mean value of intervals between the groove parts having a depth of 0.2 μm or greater from the mean line is 79-280 μm.
