The clip 1 comprises an upper member 21 and a lower member 22. The upper member 21 includes: an upper body 25 which is placed on both the lips; a supporting piece 28 extending from the upper body to a top face of the lower wall; an abutting piece 31 extending from the upper body to cross a lower side of the lower wall and is abutted to a side face 9 of the vertical wall; and a via hole 38 formed in the upper body. The lower member 22 includes: a bolt 23 which includes a head 52 to be abutted to the upper body in the proximal end thereof, and is put through the via hole into the ceiling joist; and a female screw hole 42 to which a distal end of the bolt is threaded, and holds the lips between the lower member 22 and the upper body by threading a screw member into the female screw hole. |
