PROBLEM TO BE SOLVED: To provide a structure of packaging parts having an impact resistance and a cushioning characteristic kept in balance to secure the quality of a contained part. SOLUTION: A holding plate A having cut-outs A prolonged from one edge to the other in the vertical direction near to the both sides of a corrugated fiberboard cut in a predetermined size and horizontal cut-outs A prolonged in an inner direction from predetermined places on both sides and a holding plate B having cut-outs B and horizontal cut-out B formed in the same manner as in the holding plate A in a corrugated fiberboard cut in a predetermined size, are assembled in parallel crosses by inserting the cut-outs A and B each other to form an inner partition part. Then a reinforcing plate A having cut-outs C, which can be inserted in the horizontal cut-out A each other, on a corrugated fiberboard cut in a predetermined size and a reinforcing plate B having cut-outs D, which can be inserted in the horizontal cut-out B each other, in the same manner as in the reinforcing plate A, are mounted so that each end edges come in contact with the four outer side surfaces of the inner partition part or are close to them.
