  • the joint member 110B has a circular opening 110a. Furthermore, a recess 115 (also called a notch) is provided in communication with the opening 110a.
  • the recess 115 of the joint member 110B has a shape corresponding to the protrusion 138 of the fixing member 130B (in other words, the recess 115 and the protrusion 138 have a key-keyhole relationship).
  • the width in one direction of the protrusion 138 of the fixing member 130B is smaller than the width in one direction of the recess 115 of the joint member 110B.
  • the width in one direction of the protrusion of the fixing member 130B is smaller than the width in one direction of the recess 115 of the joint member 110 so that a gap of about several millimeters is formed when the fixing member 130B is fitted into the joint member 110.
  • the convex portion 138 of the fixing member 130B fits into the concave portion 115 of the joint member 110B, fixing the position of the fixing member 130B and stabilizing the assembled structure 100B.
  • FIG. 21 is a schematic perspective view of the fixing member 130C according to this embodiment.
  • FIG. 22 is a schematic view showing a method of assembling the assembly structure 100C according to this embodiment.
  • the fixing member 130C extends on the side having the first recess 133.
  • the fixing member 130C has a notch 139 at a position corresponding to each surface of the joint member 110C.
  • the notch 139 includes a first notch 139a and a second notch 139b extending in the direction in which the fixing member 130C extends (fifth direction D5).
  • the first notch 139a and the second notch 139b are provided in a continuous manner and are perpendicular to each other at a predetermined position.
  • the width W139a of the first notch 139a and the width W139b of the second notch 139b are larger than the width W127 of the third columnar portion of the frame member 120 and smaller than the width W129 of the tip protrusion 129.
  • the frame member 120 is inserted into the joint member 110A, and then the fixing member 130C is inserted.
  • the fixing member 130C has the cutout portion 139, it can be inserted to the back without contacting the frame member 120A even if it is longer in the longitudinal direction than in the second embodiment.
  • the fixing member 130 is inserted until it contacts the end of the first cutout portion 139a.
  • the fixing member 130 is rotated clockwise. This action causes the frame member 120 to contact the end of the second cutout portion 139b.
  • the screw 140 is inserted through the through hole 131 of the fixing member 130 to fasten the frame member 120 facing the fixing member 130 to the screw 140.
  • the movement of the frame member 120 is suppressed by the cutout portion 139 together with the first recess 133 of the fixing member 130. This makes it possible to resist forces from a direction intersecting the extension direction of the frame member 120. This makes it possible to stabilize the structure of the assembled structure 100C.
  • the cutout portion 139 has a shape (first cutout portion 139a and second cutout portion 139b) that extends in one direction (longitudinal direction) and intersects at a predetermined position, but the present invention is not limited to this.
  • FIG. 23 is a schematic perspective view of another aspect of the fixing member 130C according to this embodiment. As shown in FIG. 23, the cutout portion 139 may be provided so as to extend in a direction (diagonal direction) that intersects with the direction in which the fixing member 130C extends (longitudinal direction).
  • the width W139 of the cutout portion 139 is larger than the width W127 of the third columnar portion of the frame member 120 and smaller than the width W129 of the tip protrusion 129. This configuration can also resist a force from the extension direction of the frame member 120, as in the cases of FIGS. 21 and 22. This can stabilize the structure in the assembled structure.
  • Fig. 24 is a schematic perspective view of a fixing member 130D according to this embodiment.
  • Fig. 25 is a schematic view showing a method of assembling an assembly structure 100D according to this embodiment.
  • a screw portion 133c is provided in the first recess 133 on the first surface 130Da side of the fixing member 130D.
  • the fixing member 130D does not have a through hole or a second recess.
  • the second surface 130Db facing the first recess 133 may be flat, or may have a recess 136 large enough to fit the tip of a flat-head screwdriver.
  • the screw portion 133c is inserted into the screw hole 129a of the lower frame member 120A-3 arranged opposite the fixing member 130D. As a result, all of the frame members 120 are fixed.
  • the joint member 110 has a cubic structure as a hexahedral structure, but the present invention is not limited to this.
  • the joint member 110 may be a rectangular parallelepiped.
  • the joint member 110 is not limited to a hexahedron and may be a tetrahedron depending on the application.
  • the joint member 110 may have a spherical structure.
  • the opening 110a is a square, but the present invention is not limited to this.
  • the opening 110a may be a rhombus, parallelogram, rectangle, or a polyhedron such as a triangle, hexagon, or star.
  • the opening is a circle, but the present invention is not limited to this.
  • the opening may be an ellipse or another shape having a curve.
