PURPOSE:To prevent a reduction in heat-collecting efficiency from occurring due to the tarnishing of the surface of a transparent plate by fitting a cleaning member to at least one of a pair of movable members which can move along the upper and the lower surface of the transparent plate of a solar heat collector and are attracted to each other by magnetic force. CONSTITUTION:A pair of magnets 6, 7 are placed on the upper and the lower side of the transparent plate 5 and are attracted to each other by the magnetic force, with the plate 5 therebetween. The cleaning members 9, 9' such as a fabric are fixed to the lower surface of the upper-side magnet 6 and the upper surface of the lower-side magnet 7, and are in contact with the upper surface 10 and the lower surface 10' of the transparent plate 5, respectively. Since the transparent plate 5 is generally stained more easily on the upper surface 10 than on the lower surface 10', the lower-side cleaning member 9' may be omitted by fitting the cleaning member 9 to only the magnet 6.
