To provide a fastening fitting in which mounting workability is not complicated and fear of that a welded portion of a pressing fitting is removed or the pressing fitting is deformed even if it is repeatedly trodden by a caterpillar of a heavy vehicle at any time is made less.

Both side edges in a width direction of the pressing fitting (20) having a cross section shape having a center in a width direction swelled as compared with both side edges in the width direction are fixed to a steel plate deck (31) by welding, and a base part (10A) of a D type eye plate (10) engaged with a hook of a lashing chain is inclinably engaged with the pressing fitting. Whereas, the pressing fitting is manufactured by a steel material having a hot forging organization. Both ends (21) in a longitudinal direction of the pressing fitting may be swelled/formed to a thick portion as compared with a central portion.
