  However, the conventional file box shown in FIG. 4 has a large number of parts because the perforated disc 15 and the eyelet 14 are used to fasten the upper plate 4, the lower plate 5 and the eyelet plate 12. As a result, there are disadvantages that the number of manufacturing processes increases as much as the eye catches, the operation time is increased, and the cost is increased.

 Further, since the perforated disk 15 is weighted on the upper plate 4 and the heads of the eyelets 14 protrude outward, when the plurality of file boxes are stored side by side in the cabinet, the protruding holes The head of the perforated disk 15 or the eyelet 14 hits the side plate of the adjacent file box and is difficult to store. As a result, a gap is created and the storage area is increased, and the file boxes cannot be arranged in order and stored in the cabinet, and the inside of the cabinet may not be used effectively.

 In addition, since the file box is made of several kinds of materials such as resin and metal, it is necessary to separate the materials for each material when discarding, and thus there is a problem that recycling is not easy.

  Therefore, the present invention reduces the number of parts without using a perforated disk or eye, reduces the number of manufacturing steps, and makes it easy to store the file box in the cabinet. It is possible to provide a file box that can be easily recycled.

  The file box of the present invention includes a bottom plate, pressing plates provided on both sides of the bottom plate, front and rear plates connected to the top and bottom of the bottom plate, an upper plate connected to both sides of the front plate, and a rear plate. A lower plate connected to both sides of the plate is integrally formed, a long slot for locking is formed on the bottom plate side of each lower plate, and a lower plate is connected to the bottom plate side of each upper plate. The locking pieces inserted into the locking long holes and locked are connected via the notches, the presser plate, the lower plate, and the upper plate are sequentially stacked, and the locking pieces on the upper plate are the locking lengths for the lower plate. The lower plate is inserted into the hole and locked to the back side of the lower plate, and the lower plate is pressed against the upper plate by the elasticity of the press plate.

    Since the file box of the present invention can be formed with a single sheet without using a perforated disk or eyelet, the number of parts can be reduced, and the number of manufacturing processes can be reduced by that amount. Since the perforated disk and the projection by the eyes are eliminated, the file box is not easily interfered with by a step on the inner side surface of the cabinet, and can be stored smoothly. Moreover, the inside of a cabinet can be utilized effectively.

  In addition, since the file box of the present invention can be formed of a single sheet of material, there is no need to use other materials such as metal eyelets, so there is no need to separate when recycling after use. Easy.
