A caster wherein the web of the bifurcated frame for the wheel and the carrier for the frame define a plain thrust bearing which allows the frame to swivel relative to the carrier about an axis extending at right angles to the axis of the wheel. The frame and the carrier have abutting surfaces and are held against axial movement away from each other by a ring-shaped coupling.
