PROBLEM TO BE SOLVED: To provide a joint device of a structure, which enhances axial dimensional accuracy in a coupled state, eliminates play in a joint body, and allows the paired joint bodies to be coupled and disassembled through one-touch operation. SOLUTION: Characteristically, this joint device of the structure is equipped with a pair of fixing rings which are fixed to truss members and have butting surfaces butting against each other when the truss members are coupled to each other, the joint bodies 6 which are provided on the outer peripheries of the fixing rings 5, a plurality of fitting protrusions 12 which are provided at the tips of the joint bodies 6 and axially protruded at prescribed intervals along a circumferential direction, fitting recesses 13 which are formed among the fitting protrusions 12, and locking hook parts 14 which are provided in the fitting protrusions 12 and circumferentially locked to the fitting protrusions 12 of the other-side joint body 6 so as to regulate axial movement; in the fitting protrusions 12 and fitting recesses 13 of the paired joint bodies 6, the fitting protrusions 12 and fitting recesses 13 of one-side joint body 6 are mutually fitted into the fitting recesses 13 and fitting protrusions 12 of the other- side joint body 6 in an axial direction; and the hook part 14 has an engaging surface 14a which is inclined in the direction of the tip of the fitting protrusion 12 with respect to a surface perpendicular to the axial direction of the joint body 6.
