Abstract
A three-dimensional framed structure is built up by interconnecting rod members end to end by knuckle members. Each rod member includes, at either end, a sleeve in which a connecting bolt is axially inserted from the inner side, and a rotary member disposed at an outer end of the sleeve in such a manner that each said rotary member is not turnable relative to the connecting bolt and is movable axially relative thereto. A temporarily holding means is carried by the sleeve. The temporarily holding means can project outwardly from an outer peripheral surface of the sleeve to temporarily hold the bolt from being axially moved relative to the rotary member until the bolt is screwed into one of screw holes of one of the knuckle members to some extent, and the temporarily holding means can be retracted into the sleeve, until it is flush with the outer peripheral surface of the sleeve, when the bolt is screwed into the one screw hole of the knuckle member to some extent.
