PURPOSE: A space truss for constructing a three-dimensional structure is provided to prevent a linear bolt from becoming separated from a linear sleeve pipe using a linear pin. CONSTITUTION: A space truss for constructing a three-dimensional structure comprises a connector(110), a linear bolt(120), a linear sleeve pipe(130), a cone(140), and a post pipe(150). Multiple screw grooves(112) are formed on the outer surfaces of the connector. The linear bolt is composed of a screw part(122), a shaft part(124), and a head part(126). The screw part is inserted into the insertion grooves of the connector. The shaft part is integrally connected to the screw part. The head part is integrally connected to the shaft part. The linear sleeve pipe is coupled to the shaft part of the linear bolt to reinforce the strength of the linear bolt. The cone is located between the linear bolt and the linear sleeve pipe and has a through hole(142) in which the shaft part is inserted. The post pipe is connected to the cone.
