Claims

[Claims for Utility Model Registration] (1) The distal end portion forms a tapered portion that becomes larger in diameter toward the open end, and a plurality of slits extending in the axial direction from the open end are provided, and any one of the slits The sleeve has a base engagement groove formed in each slit, and is formed into a rectangular shape with a bolt hole for a bolt that tapers toward the tip in the center, and the side plates on the opposing sides are bent downward to form a concave bottom or A locking member formed into an engaging piece that holds a stopper formed at the bottom of the convex portion, and a cut-off cone nut having a tapered portion that becomes larger in diameter toward the tip and an inner diameter that becomes larger toward the base end. The tapered part of the cone nut is joined to the tapered part of the tip of the sleeve, and the claw provided at the periphery of the bolt hole of the rotation prevention member is engaged with the base engagement groove, and the cone nut is pulled up by a pulling means. A fastening fitting for corrugated steel plate, characterized in that it is provided with means for moving the cone nut toward the base of the sleeve by moving the cone nut toward the base of the sleeve. (2) A tip engaging groove is formed in one of the slits of the sleeve, and a projection is provided on the tapered portion that becomes larger in diameter toward the tip of the cone nut, and the projection is engaged with the tip engaging groove. A fastening fitting for a corrugated steel plate according to claim 1.
