<p>PROBLEM TO BE SOLVED: To easily provide a stable installation state without causing looseness, and to easily provide even waterproofness when necessary, in a support device for installing an apparatus in an installation part such as a rooftop.SOLUTION: A fixing support device 11 is provided for fastening and fixing by a nut 14 by holding receiving hardware 15 for receiving an installation object to a support bolt 13 erected in an installation part 12, and an upper side angle changing mechanism part 21 is arranged on the upper side of the receiving hardware 15, and a lower side angle changing mechanism part 31 is arranged on the lower side, and these are fastened and fixed toward the installation part by a nut 14. The lower end of the lower side angle changing mechanism part 31 is provided with an elastic material 40 to be brought into pressure contact with an installation surface 12 when the upper side angle changing mechanism part 21 is fastened by the nut 14, and prevents looseness of the nut 14, and water cutoff performance is provided between the installation surface 12 and itself. The upper side angle changing mechanism part 21 and the lower side angle changing mechanism part 31 are formed with relatively sliding convex spherical surfaces 26 and 36 and concave spherical surfaces 27 and 37, to absorb an inclination of the support bolt 13.</p> |
