This drawer is composed of a rectangular frame which forms a storage space for storage, a bottom plate of a rectangular frame and a front panel mounted on a rectangular frame, which has a handle. The assembling process of the drawer having the above-described structure is performed by assembling the four plate members to form a square frame and assembling the square frame to the bottom plate. Then, the front plate larger than the plate members constituting the square frame is mounted on the plate frame of the square frame. Since the front plate is larger than the rectangular frame, the frame of the rectangular frame is fixed to the central area of the front plate so as to be overlapped, and then the mounting operation is performed with the fastening screw.

However, the fixing devices are not obstructed and aligned with respect to the plate surface movement of the plates in the overlapped state. In order to position the rectangular frame plate so that it overlaps the central region of the front plate, the user marks the mounting position of the frame plate on the front plate. Afterwards, the user must move the front plate and align the frame of the frame with the mounting position shown and fix it with the fixing device. Since it is necessary to perform various processes in this way, there is a problem that mounting work is troublesome and work time is long.

[ The user inserts the first latching support 41 into the second latching support 42 so that the latching portion 43 is caught by the plate material 2. [

Thus, the user fastens the fastening screws to the flat plate materials 2, 2-1 to attach the two plate materials 2, 2-1.

In the above-described embodiment, the clamping member 30 is rotated by screwing to clamp the flat plate materials 2 and 2-1. However, as in the case of the first fixing rims 21-32, It may be implemented so as to clamp the flat plate material 2, 2-1.

In another embodiment, the clamping member 30 may be provided to clamp the flat plate material using an elastic member such as a refrigerator door.

Since the thickness of the flat plate materials 2 and 2-1 may vary and overlapping positions on the stairs may vary, a small strip rod may be provided and inserted between the clamping arm 2 and the flat plate materials 2 and 2-1 So as to be properly fixed.

The second latching support 42 may be elastically urged by the elastic member in a direction to be inserted into the first latching support 41 so as to prevent the flat plate material 2 and 2-1 from being separated. The second latching support 42 may further include an elastic member for applying elasticity to rotate in the clamping direction. Thus, it is possible to always prevent the engaging portion 43 of the separation preventing member 40 from separating the flat plate materials 2, 2-1.

The flat plate materials 2 and 2-1 can be easily inserted by the clamp overlapping clamping device 10 with the clamper arms 20 having a stepped shape to have a shape in which the plates are overlapped to be shifted along the plate surface direction . The flat plate materials 2 and 2-1 which are superimposed and shifted along the plate surface direction by the clamping member 30 can be clamped and fixed. The separation preventing member 40 can prevent the flat sheet material 2, 2-1 from deviating in the sheet surface direction. Thus, the mounting operation of the flat plate material 2 and the flat plate material 2-1 can be performed easily and stably with accuracy.
