PROBLEM TO BE SOLVED: To provide a connection mechanism of hanging rods for a ceiling board which are easily connected. SOLUTION: A vertically long insertion hole is formed in a main board part 4 of one side hanging rod 1 for a ceiling board, and base board parts 21 which are projected from end parts and butted on side faces of the main board part of the one side hanging rod 1 and U-shaped connecting projection parts 23 which are extended from the base board parts 21 are provided in the end parts of the other side hanging rod 1. The connecting projection parts 23 are press-fitted in the insertion hole 10, edges f of folding parts 24 are brought into contact with the side faces of the main board part 4 at the peripheral edge of the insertion hole, as a result, the connecting projection parts 23 are connected inseparably to the insertion hole 10. In this structure, even though the U-shaped connecting projection parts 23 which are projected in the one side of the hanging rod for a ceiling board are simply brought into press fitting in the insertion hole 10 which is formed in the main board part 4 of the other side hanging rod 1 for a ceiling board, connection is easy, assembling is simple and skills are not required. |
