The invention relates to a twin-wheel caster provided with a housing containing a journal opening on a top side thereof, which is oriented in a substantially vertical direction for receiving a pivot connecting a roller to a furniture or another object, a shaft-shaped slide opening on the lower side thereof, which is laterally offset with respect to the journal opening and used for receiving a cross head supported by the housing with the aid of a spring, wherein the cross head has a through opening which is oriented in a substantially perpendicular direction with respect to the shaft-shaped slide opening and receives a swivel pin bearing two wheels, is placed in the housing in such a way that it is slidable between rolling and braking positions and recesses embodied in the slide opening limiting walls and used for passing the swivel pin. The housing has two projections which are arranged in the internal space thereof, adjacent to the slide opening, laterally extend from the housing wall and frictionally support two hubs of the wheels in the braking position.
A twin-wheel caster comprising a housing having an essentially vertically oriented, top-side pin opening receiving a pivot pin which connects the caster to an item of furniture or to another object, a shaft-shaped, bottom-side slide opening in the housing which is offset laterally with respect to the pin opening and receives a slide which is supported in the slide opening via a spring and can be displaced between a rolling position and a braking position, a passage opening provided in the slide, oriented essentially transversely with respect to the slide opening and containing an axle pin bearing wheels, and recesses provided in the housing wall bounding the slide opening for passage of the axle pin, characterized in that the housing has, in its lower region, two projections which adjoin the slide opening, protrude laterally from the housing wall and frictionally support the hubs of the wheels in the braking position.
