摘要

PROBLEM TO BE SOLVED: To facilitate work setting a fastening metal fitting in an inner through slit. ;SOLUTION: In the press plate piece 10 of a fastening metal fitting A one pair of turning end edges 15 disposed at a 180° rotation symmetry position centering the center point (a) of the press plate piece 10 having a shape of the cutting-off vicinities of the apexes of its corner portions are formed so that the length d5 of a line segment (b) joining an arbitrary point (f) and the center point (a) is 1/2 of the slit width d3 of the inner through slit 4 of plate material B with slit or less. A turning operation turning the direction of the press plate piece 10 in the inner through slit 4 is made to be possible.;COPYRIGHT: (C)1999,JPO
