Next, as shown in FIG. 5, the tool (20) is inserted into the hexagonal hole (19), and the connecting rod (15) is rotated in the tightening direction, so that the upper and lower engaging members (12) (13) Are tightened in a direction close to each other, the two adjacent unit partition panels (1) and (1) are firmly connected to each other, and the adjacent unit partition panels (1) are connected to each other in the same manner. By sequentially connecting, a main partition panel (2) continuous in the left-right direction is formed.
[0028]
Further, as shown in FIG. 6, a connecting mechanism (A) in the unit partition panel (1) constituting the sub partition panel (3) is provided on the front surface of the main partition panel (2) thus formed. The upper end of the engaging claw (12a) into the upper rail member (5) and the lower engaging claw (13a) into the lower rail member (6). The Since the upper and lower engaging members (12) and (13) are loosely fitted to the connecting rod (15), the engaging claws (12a) and (13a) have an upward piece (5a) and a downward piece (6a). Can be inserted into the rail members (5) and (6).
[0029]
Next, as shown in FIG. 7, by inserting the tool (20) into the hexagonal hole (19) of the connecting rod (15) and rotating in the tightening direction, the degree of screwing into the square nut (16) is increased. If the diameter is increased, the engagement claw (12a) is closely engaged with the upward piece (5a) of the upper rail member (5) by the contact between the enlarged diameter head (15b) and the upper engagement member (12). By the contact between the square nut (16) and the lower engaging member (13), the engaging claw (13a) is tightened so as to closely engage the downward piece (6a) of the lower rail member (6). The connection between the main partition panel (2) and the sub partition panel (3) is completed.
[0030]
As shown in FIG. 1, when the sub-partition panel (3) is constituted by a plurality of unit partition panels (1), they are connected in the same manner as in the main partition panel (2) with their orientations in the front-rear direction. That's fine.
[0031]
In the modification shown in FIG. 8, the upper and lower engaging members (12) and (13) are formed by bending a plate material. However, both side portions of the plate material are bent inwardly and vertically. A pair of hook-shaped engaging claws (12a) (13a) is formed at the tip of the bent piece.
