  However, the brake assembly of the drum brake usually has various shapes depending on the type of automobile to be used, such as the shape of the bracket chamber and the thickness of the brake drum (the height of the cylindrical portion).

  And since the conventional packing materials and methods as described above are formed using wood and nails, nailing is necessary, so there are many work steps for unpacking and packing. There is a problem that the efficiency is poor, skill is required for the work, and the material is discarded every time, so that the cost is increased.

  Also, it is not possible to pack articles with cylindrical parts of different shapes for each type with the same packing material, and each time a differently shaped frame must be formed. Different parts had to be prepared, the work efficiency was poor, the work required skill, and the cost was high.

  Furthermore, an empty space was generated in the wooden frame, and the efficiency of storage and transportation was poor. In particular, when a wooden frame is stored in a container having a predetermined volume, the arrangement of the brake assembly in the wooden frame is limited. For example, when the wooden frame is arranged with a step up and down, the wooden frame is moved up and down. It was impossible to stack the layers, and the number of brake assemblies stored in the container decreased, and this problem was remarkable.

  Therefore, the present invention reduces the number of work steps for packing or unpacking, and enables packing of articles having cylindrical parts such as brake assemblies having different shapes with the same packing material, The purpose is to facilitate and increase the efficiency of the work, and to pack the drum-type parts at a low cost.
