Abstract
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.
