PURPOSE:To facilitate the regulation of the position of a heat collecting pipe, permit the absorption of shock as well as the release of expansion and contraction due to thermal expansion and reduce heat loss to a heat collecting case by a method wherein the heat collecting pipe is supported by a bent elastic member. CONSTITUTION:A plurality of mirrors are arranged in parallel on a base table and a heat collecting unit 1, equipped with a heat collecting pipe 4, is arranged above said mirrors to collect solar beams, reflected by said mirrors, to the heat collecting pipe 4. The heat collecting pipe 4 is supported by a bent elastic member 5 consisting of a wire. As a result, the regulation of the position of the heat collecting pipe 4 may be facilitated and shock may be absorbed. Further, expansion and contraction due to thermal expansion may be released by sliding between the heat collecting pipe 4 and the elastic member 5 while heat loss from the heat collecting pipe 4 to a heat collecting case may be reduced.
