ABSTRACT:
A caster includes a wheel, and a connecting shaft mechanism for holding the wheel in position; the shaft mechanism includes a sleeve consisting of two half parts, and a supporting shank member, which is held in the sleeve at an upper end, and with which the wheel is connected; the supporting shank member is formed with two flat portions, which face outwards in opposite directions; the sleeve half parts are connected together by means of bolts with inward sides thereof facing each other; each of the sleeve half parts has a flat portion on the inward side thereof; the flat portions of the sleeve half parts touch respective ones of the flat portions of the supporting shank member for preventing angular displacement of the supporting shank member relative to the sleeve.
