PROBLEM TO BE SOLVED: To reduce weight in a support part which supports a mechanism for deflecting a reflection surface.SOLUTION: A solar light collector has: a main shaft part which is long in an axial direction; a rotation mechanism which rotates the main shaft part; a tabular reflection part 3; and a tabular opposing part 6. The reflection part 3 has a reflection surface 30 spreading in an axial direction and in a width direction perpendicular to the axial direction as an upper surface, and its lower surface is fixed at the main shaft part. The opposing part 6 extends to both sides of the width direction from the main shaft part, and both end parts of the width direction oppose to both end parts of the reflection part 3 in the width direction, in the axial direction and in a center normal direction perpendicular to the width direction. A deflection mechanism 7 which changes a deflection amount of the reflection part 3 and the opposing part 6 according to the rotation of the main shaft part is provided between an end part of the reflection part 3 and an end part of the opposing part 6. When the deflection mechanism 7 moves the end part of the reflection part 3 simultaneously with the end part of the opposing part 6 in the opposite directions with respect to the center normal direction, reaction forces acting on the deflection mechanism 7 from the reflection part 3 and the opposing part 6 are cancelled with each other, so that the deflection mechanism 7 can be supported by a light-weight support part. |
