A two-dimensional movement closed-link structure (1) for supporting a moving object (2) so that the moving object (2) can freely move in a plane is provided with a fixed link (50), a first link (10) one end of which is rotatably connected to one end of the fixed link (50), a second link (20) one end of which is rotatably connected to the other end of the first link (10), a third link (30) one end of which is rotatably connected to the other end of the second link (20), and a fourth link (40) one end of which is rotatably connected to the other end of the third link (30) and the other end of which is rotatably connected to the other end of the fixed link (50), the second link (20) having joint parts (21, 22) at both ends at which the second link (20) is connected, and a bar part (23) for integrally combining the joint parts (21, 22) at both ends thereof, and the moving object (2) being disposed in the bar part (23) of the second link (20). By this configuration, the rigidity with which the moving object is supported can be maintained, movement precision can be enhanced, and a wide range of mobility can be maintained. |
