<p>The castor has a housing (10) with two projections (38, 38`) that are arranged in a lower area of the housing. The projections are provided adjacent to a shaft-shaped slide opening (16) which receives a slide having a through opening to receive a bolt (22). The projections laterally extend from a housing wall over a width of the opening (16) to frictionally support two hubs of wheels (26, 26`) in a braking position. The projections have semi-circular slots provided adjacent to recesses in wall sections. The slide and the housing are made up of polypropylene or polyamide plastic.</p> |
