<p><P>PROBLEM TO BE SOLVED: To provide an attachment device for a roof-top installation which can easily rotate the head of a bolt and enables workability to be improved. <P>SOLUTION: A male screw shaft 4B extending downward from a head 4A of a bolt 4 is inserted downward from above into a push-in member 2 to press from above a roof-top installation, a solar panel 30, which is mounted on a rail member 40 installed on a roof 50. When the head 4A of the bolt 4, which is rotated, applies a downward pressurization load to the push-in member 2, the solar panel 30 is caught and fixed by the push-in member 2 and the rail member 40. Consequently, the height position of the head 4A of the bolt 4 is the same with the height position of the top face of the solar panel 30 at the arrangement position of the bolt 4 or is higher than it. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
