A bearing fitting between the castor body (3) and the trolley body of pushable trolley, which enables the castor body to pivot relative to the trolley, comprises a vertical tube (1), forming a part of the trolley body, which is received in a socket (6) of the plastic body (3). The lower end of the vertical tube (1) is fitted with a plastic stopper (4). Between this plastic stopper (4) and the bottom of the receiving-socket (6) is a metal plate (5) acting as a bearing surface. A plastic cap (7) forming a splash guard surrounds the vertical tube (1) with compression tightness and from the cap (7) extends a sleeve (8) which surrounds the tube (1) and is rotatable relative to the socket (6). <IMAGE> |
