摘要： PROBLEM TO BE SOLVED: To make it possible to increase the distances between connection points for multiple expanding and contracting members and a base structure and to increase the storability and rigidity, and to facilitate attitude and position precision control in space by using link mechanisms which can be expanded synchronously with an expansion structure to be supported. SOLUTION: The expanding and contracting members 1 to 3 are coupled with the expansion structure 40 through universal joints 4 to 6 and there coupled with link mechanism 11, 12, and 13 through joints 7, 8, and 9. After the link mechanisms 11 to 13 are expanded with the driving force of a spiral spring, the latch mechanism of a hinge operates to restrict the relative rotation of a rod-shaped member and thus a truss structure is approximately obtained to form a rigid structure. The expanding and contracting members 1 to 3 move two cylindrical members through the driving of a motor to vary the relative distance between the expansion structure 40 and base structure 30, and the expansion structure is rotated on a spherical joint 10 as a pivot point around a pitch axis, a roll axis, and a yaw axis to perform attitude control.

摘要： PROBLEM TO BE SOLVED: To prevent deformation by mounting a shape retaining member called a loading path between members of more than one quadrilateral linking mechanism adjacent to each other in a stored condition and between more than one module structure. SOLUTION: Many loading paths 32, 33, 34, 35 are provided along the circumferences of six sets of quadrilateral linking mechanisms 14, 15 to 19 arranged radially and in the quadrilateral linking mechanism 14, two loading paths 32, 33 are attached to one outside member 22. In addition, the loading paths 34, 35 in adjacent positions like the loading paths attached to the quadrilateral linking mechanisms 14, 19 can be linked together and separated. In addition, by fitting the loading paths 32 to 35 in mutually adjacent positions, their relative movements are constrained, and an expansive truss structure is arranged in a rocket faring in a completely stored state. Therefore, even when an external force or vibration is applied, interference between more than one member prevents the quadrilateral linking mechanisms form deforming.
