ABSTRACT:
A joint structure for a structural bar assembly, wherein a first bar and a hollow second bar are assembled by inserting of fitting a web of the first bar into a transverse slot of the second bar, and by restoring a stopper plate of the web elastically or forcibly to an upwardly inclined state so as to allow a top end of the stopper plate to engage or contact with an inner surface of a front wall of the second bar after the stopper plate passes through the slot. Joint portions of the first bar and the second bar are not pressed or hit strongly. There is no fear of rusting and eroding in the joint portions owing to injury of plating or painting layers.
