Therefore, there is a problem that the number of parts is increased and it takes time and cost to manufacture the members, and further, it is necessary to identify each part at the time of assembling, which requires a lot of time. In addition, when the truss structure can be deployed and stored, the intersection angle of the members of the hinge of the truss structure during the deployment and storage process differs for each hinge, making it very difficult to calculate all intersection angles. Met.
