Claim:
A sliding bearing comprising: a first bearing body having an annular surface; a second bearing body which is superposed on said first bearing body so as to be rotatable about an axis of said first bearing body, and has an annular surface opposed to the annular surface of said first bearing body; and a synthetic resin-made annular sheet which is interposed between the annular surfaces and slidably abuts against at least one of said bearing bodies, said second bearing body having a projection formed integrally on the annular surface thereof, and said sheet being interposed between said projection and the annular surface of said first bearing body and slidably abuts against the annular surface of said first bearing body, said projection includes at least an inner annular projection disposed on an inner peripheral portion of the annular surface of said second bearing body and an outer annular projection disposed on the annular surface of said second bearing body radially outwardly of and substantially concentrically with said inner annular projection, said inner and outer annular projections abutting against said sheet, said second bearing body being formed on the annular surface thereof with a recess which is surrounded by said outer annular projection, and by which said inner annular projection is surrounded, an annular closed space being formed between said annular sheet and the annular surface of said first bearing body and corresponding to said recess, said annular closed space, in which a fluid is filled, being closed by said annular sheet and the annular surface of said first bearing body.
