PURPOSE:To improve the usability by forming a side wall which forms the accommodation part of a knapsack body, so as to be opened and closed. CONSTITUTION:A side wall 4 which forms an accommodation part 1 is connected in separable manner with front and rear walls 7 and 8 by the fasteners 5 and 6 which are arranged from the upper edge to the lower edge in the front and rear parts. The side wall 4 is connected with the front and rear walls 7 and 8 by upwardly moving the opening/closing metal fittings 5a and 6a of both the fasteners, and the side wall 4 is separated from the front and rear walls 7 and 8 by downwardly moving both the opening/closing metal fittings 5a and 6a, and the side wall 4 can be opened as shown by the chained line in the Fig.1, having a bottom wall 9 part as base point. Further, a reinforcing metal fitting 10 is interposed between the front and back members 4a and 4b which form the side wall 4, and is fixed between the front and back members 4a and 4b by caulking the front and back members 4a and 4b by a pin 11. Accordingly, when a textbook is put in/out from an accommodation part, the side wall is opened without opening an upper cover, and the textbook can be put in/out. |
