In a self-assembly frame component prepared by the present invention, a bolt is in contact with the bottom of a head unit, and has a non-fixated column unit in a shape of permitting the rotation of a strip when inserted into a fastening hole on the strip. A column shaped fixated column unit is placed between the non-fixated column unit and a cylindrical body, has the shortest diameter which is longer than the diameter of the cylindrical body, and has a cross section in a figure shape other than a rotational symmetrical circle in all directions. The strip is formed in a plate shape, and has fastening holes in a shape of penetrating the plate surface. At least one of the fastening holes are formed to be combined with the fixated column unit of the bolt. Thus, when the fixated column unit is inserted into the fastening hole, the rotation of the strip to a shaft of the bolt is to be restricted. Therefore, when fastening multiple strips, the fastening state of the bolt and the nut can be stably maintained using only one nut without using two or three nuts. |
