CONSTITUTION: A space frame comprises a plurality of arm units(15) and connection members(70). The arm unit comprises a rod(20), a cover member(30), a fixing member(40), a joining unit(50), and a sealing unit(60). The rod comprises a hollow portion inside. The cover member is fixed to the end of the rod, and comprises a support hole. One end of the fixing member is inserted into the support hole, and the other end comprises a head portion(42) supported to the cover member. The joint portion connects the fixing member to the connection member. The sealing portion is installed between the cover member and the head portion, and prevents the inflow of moisture into the rod. As to the connection member, the arm units are connected to each other to form a structure.
