Is attached to the bottom surface of the end of the cut-out bottom surface P2 of the panel P2 with a screw nail (not shown) or the like. When the base material B1 and the base material B2 are brought into contact with each other, the positioning portion 22c is mounted. The receiving portion 21a is provided to have dimensions up to the same plane as the vertical surface 21a1 '.

The vertical wall 21c1 of the guide notch 21c of the first member 21 and the hanging portion 2 of the second member 22
Ratchets 2R1 and 2R2 are formed on the opposing surface 22b 'of 2b, respectively, and the second member 22 attached to the cutout bottom surface P2' of the second panel P2 is lowered to lower the vertical wall 21c1 and the vertical wall 21c1. When the opposing surfaces 22b 'are brought into contact with each other, the ratchet 2R1 and the ratchet 2R2 mesh with each other, so that the movement in the opposite direction is prevented thereafter. As a result, the same operation as in the first embodiment is obtained.

In the first embodiment, the whole is made of hard plastic, but in this embodiment, metal is used, so that the material has strength but the elasticity of the material itself is smaller than that of hard plastic. However, the cavity 22
Since b ′ is formed, elasticity is imparted to the entire structure, and engagement with the counterpart member 21 is performed smoothly.

Although the above embodiment has been described with reference to a wooden floor panel, the present invention is not limited to this and can be applied to a wall or a roof panel.
