Title:
COVER FOR SCREW HOLE
Document Type and Number:
Japanese Patent JP3520497
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To fit a cover for screw hole to a plurality of sash structural angles, each of which has different thickness, without coming off therefrom, and prevent it from protruding from the surface of the structural angle too large.
SOLUTION: A plurality of hooks 2 are integrally-formed on the back surface 1a of a surface 1, and have first, second, third locking parts 3, 4, 5 respectively so that the dimension between each of the locking part and the back surface 1a of the surface 1 may be different from each other respectively and displaced respectively inwardly and outwardly. The hooks 2 are elastically-deformed inwardly to an extent corresponding to the thickness, and one locking part is brought into contact with the opening edge of the back surface of a hole, thus it is possible to fit a cover for screw hole to a plurality of structural angles, each of which has different thickness, without coming off therefrom, and prevent the surface 1 from protruding from the surface of the structural angle too large.
