Abstract

PURPOSE:To prevent load from adding to the spring for attaching a grille even when grilles are stored being piled up by a method wherein protective pieces are cut and erected on one surface of a front holder and in a hole which is formed between the protective pieces, a spring fixing part of the grille is fitted. CONSTITUTION:A front holder 11, which protects a grille 3, is formed in a cylindrical shape with a buffer plate material such as corrugated fiberboard, etc. On one plane 11a an H shaped cut-out B is provided, and protective pieces 12, which are formed by this cut-out B, are bent by bending lines A, and a vertical erecting surface 12a and a protective surface 12b, which is in parallel with the plane 11a, are formed on the plane 11a. By the cutting out and erecting of the protective pieces 12, a hole 13 is formed on the plane 11a. The grille 3 is enveloped by the front holder 11, and end parts of the front holder 11 are bonded by a sealing tape 14. At this time, a spring fixing part 3a of the grille 3 is fitted in the hole 13 on the front holder 11, and its position is fixed. Although a spring 5 protrudes from the hole 13, the side of the spring 5 is protected by the erecting surface 13a of the protective pieces 12, and the tip of the spring 5 is protected by the protective surface 12b.
