[Problems to be solved by the device]

The pillar 7 as described above is usually formed into a C-shaped cross section by bending a long metal plate along its longitudinal direction. At the time of forming the pillar, the pillar 7 shown in FIG. The sides 7a, 7b, 7c can be accurately dimensioned by bending the metal plate according to the dimensions, but the dimension L on the open side varies greatly depending on the bending angle between the sides 7a, 7b, 7c. , It is necessary to make the angle between the sides exactly right, but it is very difficult to bend the metal plate to make the corners exactly right, and the dimension L on the open side is Very easy to make an error.
And in this case, considering the return at the time of bending the metal plate, there is a tendency that it is inevitably folded inward from a right angle,
As a result, the sides 7b and 7c of the column 7 are inclined inwardly of the right angle with respect to the side 7a, and the open side is likely to be narrowed. However, in the conventional strut mounting structure in which the lower end opening of the strut 7 is externally fitted to the strut fixing member 14 when the strut 7 is mounted to the base frame 8 or the like of the shelf 1 as described above, If the open side of the column is narrowed, it becomes extremely difficult to fit the lower end opening onto the column fixing member 14 and to attach it. For this reason, it is necessary to perform strict dimensional control in the manufacturing process of the columns, which is troublesome.

In view of the above points, the present invention is a pillar mounting structure for a movable shelf or the like, and is capable of being mounted even if the molding dimension of the pillar is not always stipulated and the opening side is narrowed, thereby manufacturing the pillar. It is to streamline the process.

[Means for solving the problem]

In order to achieve the above-mentioned object, the pillar mounting structure for a movable shelf or the like according to the present invention constitutes a base frame by front and rear frames and a plurality of vertical frames connecting the front and rear frames, and the vertical frame is at least It is formed of a bottom side and vertical sides on both sides thereof, and front and rear ends thereof are joined to the front and rear frames, and a column supporting member is attached to the bottom side portion at a predetermined distance from the front and rear frames. The lower end of the support column is supported in an internally fitted state between the front or rear frame and both vertical sides of the vertical frame and the support member.
