Abstract: PURPOSE:To achieve compaction and lightweight by constructing a hinge mechanism in such a way as to provide both divided truss members with expanding force by the elastic force of elastic members guided by a guide member so as to be elastically deformed at the time of being enclosed. CONSTITUTION:When a truss structure unit is in the enclosed state, that is, both divided members 3A1, 3A2 are in the bent positions, a guide member 14 in a hinge mechanism 10 is positioned on the opposite side to the divided members 3A1, 3A2 against a pivot 12, and the path of a wire 15 engaged with the V groove 14a of the guide member 14 becomes long, so that both coil springs 16 are elastically deformed in large degree to be in the extended state. Large tensile force thereby acts upon the wire 15, and the rotational moment obtained by multiplying the lever length from the center of the pivot 12 to the V groove 14a by the tensile force acts upon the divided members 3A1, 3A2 so as to provide both divided members 3A1, 3A2 with expanding force by the rotational moment. As the elastic members are thus disposed making efficient use of the space in the divided truss members, the hinge mechanism can be compacted as well as the whole volume of the expanding truss structure can be made small.
