Abstract: A fixing board, for an attraction-fastening type freight carrying device to be mounted on the roof of a motor vehicle, has been improved. The fixing board is composed of a magnetic attraction force contact plate, a film-like suction-cup, and a releasing handle. The magnetic attraction force contact plate has a three-layer structure comprising a soft magnet plate, an iron plate and smooth thin-film sheet coated on the iron plate. The iron plate has a plurality of grooves radially extending, which are elongated dead-end grooves. Further, the magnetic attraction force contact plate has a through-hole into which a substantially cylindrical seal lip extending from the suction film is inserted so as to make an air value. This air hole takes on a closed state when the freight carrying device is installed on the vehicle roof, and takes on an open state when being removed therefrom. The film-like suction-cup is formed throughout the circumference of the magnetic attraction force contact plate.

Abstract: An automobile roof carrier of the invention is mainly composed of a magnetic base portion, a gripping portion for removal, a covering member and a loading article holding portion. The covering member is integrally jointed over the magnetic base portion while the magnetic base portion is covered by the covering member except in the attractive surface of the magnetic base portion and the gripping portion for removal. Combined integrally in the upper part of the covering member is a loading article holding portion which is able to be opened and closed. A supplementary cover which is able to be opened and closed is attached to the covering member so that the gripping portion for removal may be hidden and exposed. There is provided a first locking mechanism for maintaining the closed state of the supplementary cover, whereas there is provided a second locking mechanism for maintaining the closed state of the loading article holding portion.
