Patent ID: 8596661

Claim:
A thrust sliding bearing comprising: a synthetic resin-made annular first bearing body having an annular upper surface and a first engaging projection; a synthetic resin-made annular second bearing body which is superposed on said first bearing body so as to be relatively rotatable about an axis of said first bearing body and has an annular lower surface opposed to the annular upper surface of said first bearing body; thrust sliding bearing means interposed between the annular upper surface of said first bearing body and the annular lower surface of said second bearing body and having at least one of a lower surface and an upper surface which is in slidable contact with at least one of the annular upper surface of said first bearing body and the annular lower surface of said second bearing body; an annular upper cover having a second engaging projection engaging the first engaging projection of said first bearing body; and an annular metal plate interposed between an annular upper surface of said second bearing body and a lower surface of said annular upper cover such that a lower surface of said annular metal plate is brought into contact with the annular upper surface of said second bearing body and an upper surface thereof is brought into contact with the lower surface of said annular upper cover, wherein said annular upper cover includes a hollow cylindrical portion having the second engaging projection and a first annular plate portion formed integrally with the hollow cylindrical portion, and said annular metal plate includes a second annular plate portion which is in contact with the annular upper surface of said second bearing body and an annular lower surface of the first annular plate portion of said annular upper cover, a third annular plate portion disposed in a through hole defined by an inner peripheral surface of the first annular plate portion of said annular upper cover, and an annular stepped portion whose one side is formed integrally with the second annular plate portion and whose other side is integrally formed with the third annular plate portion, the third annular plate portion being provided with an annular inner peripheral surface having a smaller diameter than inside diameters of annular inner peripheral surfaces of said first and second bearing bodies.
