Description

  The present invention relates to a backpack for a school bag, which is fixed to an upper part of a back pad of a school bag body.

  Conventionally, as shown in FIGS. 9 to 12, this type of shoulder belt mounting tool is fixed to the upper portion of the backrest portion T of the school bag body R, and rotates between the mounting plate 11 and the upper lid plate 12. It is assumed that an insertion portion 14 having an insertion hole 14a opened integrally is formed at the upper part of the pair of left and right coupling bodies 13 sandwiched freely. The upper end of the shoulder belt B is inserted into these insertion holes 14a, and the shoulder belt B is riveted through the rivet hole 14b provided in the insertion portion 14 through the rivet 15 (Patent Document 1).

  Therefore, the pair of backpack belts B that are riveted in this way are attached to the backpack belt fixture in a state of facing almost directly above the school bag body R. Therefore, when the user carries the school bag, the school bag body R is always pulled obliquely upward, and the shoulder belt B is kept in close contact with the user's back. It is said that B is not displaced from the shoulder due to the weight of the school bag during use, and the school bag feels heavy without feeling heavy.
