Abstract
A bearing member according to an embodiment of the present invention is formed into a single cylindrical shape or a cylindrical shape divided into arcs along a circumferential direction, and is assembled to a housing on an outer peripheral side of the bearing member. The bearing member includes an outer peripheral surface provided on a side opposed to an inner peripheral surface of the housing. A maximum height Rz (μm) of a surface roughness of the outer peripheral surface is set as 2.00 μm≤Rz≤4.00 μm, and a value of ratio between an average protruding-peak height Rpk (μm) and a load length rate Mr1 (%), that is a load curve parameter for the surface roughness is set as 0.010≤Rpk/Mr1≤0.100.
