TARPAULIN STRUCTURE

The invention relates to a tarpaulin superstructure for a movable substructure, such as a truck, a trailer, a semitrailer, a railway wagon, a dump truck or a container, comprising a top frame to which a tarpaulin made of weather-resistant material can be attached, wherein the top frame comprises a plurality of struts which can be moved along at least one guide, wherein the end of the top frame comprises an end runner which can be raised to open the superstructure and lowered to close the superstructure. A tarpaulin superstructure where the end runner is not lifted by the airstream is provided according to the invention in that an air deflection part is arranged at an end of the end runner, by means of which air deflection part the airstream is converted into a force in the closing direction of the end runner.
