A thin-wall bearing, comprising a retainer () formed in a divided type having a plurality of resin plate-like members (), (), . . . curved along an inner ring () and an outer ring (). The retainer () comprises pockets () opening to the axial end part thereof and rollingly holding balls (). Slit-like through holes () extending in the axial direction and opening to the axial end part where the opening parts () of the pockets () are positioned are formed at the center parts of pillars () between the pockets () and () adjacent to each other. As a result, the thin-wall bearing can have excellent lubricity.

Thin-wall bearing

In the slide member, a recessed and projected pattern is formed in a slide surface of a mother member of the slide member allowed to slide in contact with a mating member, recessed portions of the recessed and projected pattern are filled with a lubricant, and the area ratio of the recessed portions is set in a range of 30 to 70% while the depth thereof is set for 10 .mu.m or less. The slide member is able to secure the lubricating property, wear resisting property and seize-up resisting property of the slide surface thereof with the recessed and projected pattern formed therein for a long period.
