A wheel, primarily intended for food trolleys and the like. The drawing figure is a vertical cross-sectional view through the wheel and an associated trolley, the vertical side face (23) and bottom (24) of which are shown. The wheel has no hub in the traditional sense but is attached to the trolley close to its outer periphery. The wheel comprises an outer annular member (3), an inner annular member (10), rolling elements (6) and a lateral moulding (15). The inner annular member (10) consists of a segment of a circle, i.e. it has an open ring-shape with an engagement rib (14) arranged to be pushed into nesting relationship with the lateral moulding (15). The moulding is provided with screw holes (19) through which the wheel may be secured to the trolley by means of screws (20). |
