PURPOSE: To obtain a fixing structure of an arbitrary shape and save a wood resource by a method wherein a fixing member is made of a metal, joining parts are provided in the fixing part, and a plurality of fixing members are three-dimensionally joined through the joining parts to fix packages.

CONSTITUTION: A fixing member 1 consists of right and left frames 2 and frames 3 connecting the frames 2 to each other. The frames are made of a metal. The right and left frames are each composed of a bottom surface 2a and a side surface 2b to be L-shaped in a cross section. Slots 4 are provided in the side surface 2b. In a container 5, packages 8 each of which is a box 6 contained in a frame 7 are loaded. A space S may be sometimes generated between the container 5 and the packages 8. In this case, the packages 8 are fixed using the fixing members 1. Namely, three fixing members 1 are used by connecting the slots 4 to each other by bolts to form a triangular structure 9. The structure 9 is disposed in the space S.
