As shown in FIG. 3A, the wedge means 20 includes a fixed wedge 25 provided on a guide frame 21 fixed on the bottom plate 11,
It has a movable wedge 26 provided on the movable side plate 12a. The guide frame 21 is formed by bending a steel plate into a substantially U shape, and a relatively low first guide plate 22 provided along the peripheral edge of the bottom plate 11 and a relatively high second guide plate 22 provided in parallel with the first guide plate 22. It has a guide plate 23 and is fixed to the bottom plate 11 by spot welding at a horizontal portion connecting the two plates 22 and 23. The lower end portion of the movable side plate 12a is made of a steel plate, and that portion is bent outward to form a sliding plate 27 corresponding to the first guide plate 22, and its cross-sectional shape is a substantially upward U-shape. There is. Therefore, the movable side plate 12a is positioned and supported inside the guide frame 21 in the plane direction (left and right direction on the paper surface), and is slidable in the plane direction.

The fixed wedge 25 and the movable wedge 26 respectively include the lower ends of the second guide plate 23 and the movable side plate 12a as shown in FIG.
As shown in (a), (b) or FIG. 5 (a), a base material made of a steel plate is cut along three sides of a U-shape, and the remaining one side is extruded outward to form a tongue piece. The free end surface is a wedge surface 28. The shape of the tongue is not limited to this shape, and as shown in FIG. 5 (b), the base material is cut into two sides of the L shape, and the inside of the cut is pushed laterally into a letter shape. You may form. Further, the amount by which the tongue piece is extruded from the base material is set to the thickness of the base material.

The wedge surfaces 28 are arranged on the same plane, and when the movable wedge 26 moves in the horizontal direction together with the movable side plate 12a, they abut and overlap each other. Both wedges 2
The dimensions of 5 and 25 are about 40 mm in X in FIG.
Y is set to 15 mm on one side and 12 mm on the other side, and as a result, the inclination angle a of the wedge surface 28 where the fixed wedge 25 and the movable wedge 26 abut each other becomes about 4.3 degrees, and friction causes the engagement position. Is held immobile at.

In this embodiment, a part of the plate material is cut,
The wedge surface 28 of the fixed wedge 25 and the movable wedge 26 is formed by extruding the cut surface laterally. Therefore, even if the wedge surface 28 has a narrow width, it is possible to improve the accuracy of the squareness with respect to the guide frame 21 and the movable side plate 12a as the base material. Also, since the wedge surface 28 can be made narrow,
The space for accommodating the fixed wedge 25 and the movable wedge 26 can be made narrow, and the internal capacity of the transport packaging box 10 can be increased.

Next, a method of attaching the movable side plate 12a to the bottom plate 11 will be described. First, the bottom plate 11 is placed on the floor, and the movable side plate 12a of the guide frame 21 is placed at a position where the fixed wedge 25 and the movable wedge 26 do not collide with each other. Guide plate 22 and second

According to the first aspect of the present invention, since the wedge surfaces of the fixed wedge and the movable wedge that abut against each other are cut and extruded from the side plate or the guide frame as the base material, the fixed wedge and the movable wedge are cut. Even if and are relatively narrow, an accurate wedge surface can be obtained. Therefore, the disengagement operation of the wedge means is easy, and the disassembling work of the transport packaging box becomes easy. Further, since the wedge means having the wedge surface having a relatively small area can be housed in the relatively narrow space between the side plate and the guide frame, the internal capacity of the packaging box is not reduced. According to the invention of claim 2, the fixed wedge and the movable wedge, which are plate-shaped tongue pieces, are arranged on the same plane, so that the distance between the guide frame and the side plate can be further reduced, and the package for transportation is provided. The inner volume of the box can be increased. According to the invention of claim 3, the plate-shaped tongues forming the fixed wedge and the movable wedge can secure sufficient rigidity even if the plate thickness is thin, and can minimize the distance between the guide frame and the side plate. It is possible to increase the internal capacity of the shipping box. According to the invention of claim 4, when the fixed wedge and the movable wedge are in an abutting state, they are prevented from deviating from each other in the surface direction. Therefore, like the first guide plate 22, separation in the surface direction is prevented. There is no need to provide special means, the structure is simple, and the wedge means can be easily processed. And so on.
