PURPOSE: To reduce installation area in a folded state by connecting either one end part or the other end part of a connecting member to the first or second structure side through a rotating hinge so as to enable relative rotation to the first and second structures, around the inner part as the center.
CONSTITUTION: When one connecting member 30 is oscillated around one end part as a fulcrum so that the other end part comes close to a first structure 10, the other end part of the connecting member 30 moves linearly in the circumferential direction around the inner part and also moves radially. At this time, a second structure 20 is rotated around the inner part and rotated through a rotating hinge 60 in relation to the other end part of the connecting member 30. As a result, the other end part of the other connecting member 30 also moves circumferentially around the inner part along with the second structure 20, that is, the other connecting member 30 is also oscillated around one end part as a fulcrum only by the quantity corresponding to the rotating quantity of the second structure 20. The installation area of an expansion structure in the folded state can thereby be made small.
