Abstract
A sliding bearing includes: an upper casing; a synthetic resin-made lower casing which is superposed on the upper casing so as to be rotatable about an axis in a circumferential direction relative to the upper casing; a synthetic resin-made sliding bearing piece disposed in an annular space between the upper casing and the lower casing; and a synthetic resin-made seal member for sealing respective other annular end portions, communicating with the outside, of a gap on an inner peripheral side and a gap on an outer peripheral side in a radial direction between the upper casing and the lower casing, the gap and the gap respectively communicating with the annular space at their one annular end portions.

A synthetic resin-made thrust sliding bearing comprising:
- a synthetic resin-made upper casing;
- a synthetic resin-made lower casing superposed on said upper casing so as to be rotatable about an axis relative to said upper casing;
- a synthetic resin-made sliding bearing piece disposed between the upper casing and the lower casing;
- and a synthetic resin-made seal member integrally having a flexible inner peripheral-side annular seal portion for sealing a gap between radially inner peripheral sides of said upper casing and said lower casing, a flexible outer peripheral-side annular seal portion for sealing a gap between radially outer peripheral sides of said upper casing and said lower casing, and a connecting portion disposed in a recessed groove of the lower casing for connecting the inner peripheral-side annular seal portion and the outer peripheral-side annular seal portion to each other.
