PROBLEM TO BE SOLVED: To provide a roof hook which is composed of a plurality of members for connecting a profile rail as a member of a solar module alignment fixing system to a roof lower structure.SOLUTION: In a roof hook 200 which is composed of a plurality of members, a fixed member 210 is a right-angle angle profile having first and second fixed-side leg pieces, and the second fixed-side leg piece 212 has a first serration contour 213 at a face at the first fixed-side leg piece 211 side. In a connecting member 220, first and second connecting leg pieces have parallel longitudinal extension directions, and are connected to each other at their middle portions. The first connecting leg piece 221 has a second serration contour 225 at a face at the middle portion side, pressure is made to act on the second fixed-side leg piece and the first connecting leg piece in a state that the first serration contour and the second serration contour are fixed, thus hindering the relative movement of the connecting member and the fixed member, and in a state that the contours are not fixed, the relative movement of the connecting member and the fixed member is permitted.SELECTED DRAWING: Figure 3 |
