The rear half piece 2 is attached to the rear surface of the rear plate P1 and the front half piece 3 is attached to the rear surface of the front plate P2 in a predetermined state by attaching screws 29, respectively. This attachment is performed with the plate material P1,
If P2 is a wall, ceiling, floor, counter, or other panel material that requires on-site assembly, it can be performed at the time of factory shipment. Further, when the plate members P1 and P2 are plate members or the like for furniture construction, the furniture members can be assembled at the same time. In a state where the joining piece 21 of the front half piece 3 is fitted to the sliding guide rail 7 of the rear half piece 2,
The joining piece 21 is moved along the joining piece 5 of the rear half tool 2, and both the plate members P1 and P2 are butted to each other in the front-rear direction. Then, in the rear half piece 2 and the front half piece 3, those first
And the second engaging portion are engaged with each other. In this state, the swing lever 17 is tilted backward as shown in FIG. 4, the biasing screw 11 of the biasing mechanism 12 is tightened, and the pressure receiving piece 13 is pushed backward.
As a result, the engagement state of the first and second engagement portions is strengthened and never disengaged. As shown in FIG. 4, since the operation piece 14 of the swing lever 17 is inclined upward toward the rear, the following operation can be performed.
That is, before the plates P1 and P2 are abutted, the swing lever 17 in the front half 3 is tilted rearward, and the plates P1 and P2 are abutted in the same manner as above. The swing lever 17 allows the operating piece 14 to naturally move over the biasing screw 11 and the standing piece 10,
Simultaneously with the engagement of the first and second engaging portions, the rocking lever 17 (pressure receiving piece 13) is automatically set to the biasing mechanism 12 (however, tightening of the biasing screw 11 after setting is necessary. ).

In the present invention, it is of course possible to connect the rear half piece 2 and the front half piece 3 in the vertical direction or the like. In addition, the first engaging portion (the first engaging pin 6 and the first cutout portion 2
3) and the second engaging portion (the second engaging pin 22 and the second cutout portion 8) may be only one of them. In this case, the positional relationship between the engagement pin and the notch is relative to the rear half piece 2 and the front half piece 3 (that is, when considering from the relationship between the biasing mechanism 12 and the swing lever 17). Is. The structures and shapes of these first and second engaging portions are not limited at all. Further, the urging direction of the urging mechanism 12 is also opposite to that of the above-described embodiment when the pressure receiving piece 13 of the rocking lever 17 is structured so as not to ride over the urging mechanism 12 (disposed on the front side). become. The swing lever 17 may be swingable in the left-right direction.

[0013]

The present invention has the following effects due to the above-mentioned configuration. Since the urging mechanism acts so as to strengthen the engaged state of both coupling halves, no gap is created between the two in the coupled state of the plate members. Further, the work of connecting the plate members to each other can be performed extremely easily and surely.
