PROBLEM TO BE SOLVED: To provide a crossing brace in which a connection member for rotatably connecting two body pipes to each other can be joined to the body pipes in an inexpensive and less bulky manner with pressing work.SOLUTION: The crossing brace includes the two body pipes having grooved portions formed on the single sides of intermediate point portions with pressing work, and the connection member for rotatably connecting both body pipes to each other. The connection member consists of two U-shaped plate materials abutting each other in the opposite directions, and a rivet to be inserted into through-holes of intermediates of the connection plate materials. The two body pipes are connected to each other by looping and fixing the two U-shaped plate materials of the connection members onto the intermediate point portions with pressing work in the state of storing a head portion and a front end caulked portion of the rivet in the grooved portions, respectively. |
