PURPOSE:To widen a heliostatic movable range, by a construction wherein a flat mirror is turnably supported on a tip part of a mirror-supporting bar directed to a light-collecting surface, and an end of a sunward pointing bar having the same length as that of the mirror-supporting bar is turnably fitted to an end part of the flat mirror. CONSTITUTION:The mirror-supporting bar 32 turnably supporting the center of rotation of the flat mirror 10 is fixed on a rotary base 34. An expansion bar 40 is fixed to the center of rotation of the mirror 10, and is disposed on a bisector of the angle theta formed between the direction of the sun 28 and the direction of the light-collecting surface 26. In addition, an end of the sunward pointing bar 44 is turnably fitted to the center of rotation of the mirror 10, and the other end thereof is rotatably connected to an end of a connecting bar 46 the other end of which is connected to the lower end of the expansion bar 40, and the bar 44 is directed in the sunward direction 48. An end of a connecting bar 50 having the same length as that of the bar 46 is turnably connected to the lower end of the bar 40, and the other end thereof is turnably connected to a lower end part of the bar 32. |
