PROBLEM TO BE SOLVED: To avoid a contact between a measuring apparatus and a ground surface.SOLUTION: A supporting device 1 supports a measuring apparatus 15 vertically moved and positioned by a vertical moving device 25. The supporting device 1 is equipped with a stopper 20; and a frame 2 swingably attached to the stopper 20, attached to the vertically moving device 25 on one side over the stopper 20, and attached with the measuring apparatus 15 on the other side. The frame 2 is equipped with a first lateral frame 3 and a second lateral frame 4; a first vertical frame 5, a second vertical frame 6, and a third vertical frame 7 respectively provided between one ends, between the other ends, and between center portions of the first lateral frame 3 and the second lateral frame 4; and coupling pins 8a-8f rotatably coupling the first vertical frame 5, the second vertical frame 6, and the third vertical frame 7 and the first lateral frame 3 and the second lateral frame 4. The stopper 20 is attached to the third vertical frame 7. The first vertical frame 5 is attached to the vertical moving device 25, and the measuring apparatus 15 is attached to the second vertical frame 6. |
