Thrust sliding bearing and combination mechanism of the thrust sliding bearing and piston rod with coil spring

摘要

A thrust sliding bearing includes an synthetic resin-made annular bearing body having an annular upper surface, an annular outer peripheral surface, and an annular lower surface; a synthetic resin-made annular bearing body having an annular lower surface; a sheet metal-made reinforcement member having an annular lower surface and an annular upper surface; a synthetic resin-made thrust sliding bearing piece interposed between the annular upper surface of the reinforcement member and the annular lower surface of the bearing body; and a synthetic resin-made radial sliding bearing piece disposed between an annular inner peripheral surface of a hollow cylindrical portion of the reinforcement member and an annular outer peripheral surface of a hollow cylindrical portion of the bearing body.

主权项

1. A thrust sliding bearing comprising: a synthetic resin-made annular first bearing body having an annular upper surface and an annular lower surface; 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; a sheet metal-made reinforcement member having an annular lower surface and an annular upper surface opposed to the annular lower surface of said second bearing body; and thrust sliding bearing means interposed between the annular upper surface of said reinforcement member and the annular lower surface of said second bearing body,
wherein said first bearing body is adapted to receive at the annular lower surface thereof one end of a coil spring, and wherein said reinforcement member includes an annular plate portion having the annular lower surface of said reinforcement member and the annular upper surface of said reinforcement member, and a hollow cylindrical portion extending integrally from an inner peripheral edge of the annular plate portion in an axial direction.
