To provide a grooved nut capable of suspending and supporting an object to be lifted easily and safely while preventing damage of the object to be lifted and a wire even when the object to be lifted has an extremely large weight.SOLUTION: A grooved nut is a nut 1 screwed to a bolt part included in an object to be lifted which is suspended and supported by a wire. The grooved nut has a flange part 3 provided with a groove part 2 in an outer periphery so as to prevent positional deviation of the wire in a thickness direction when the wire is wound around it. The grooved nut is screwed to the bolt part and the wire is wound around the groove part 2 of the flange part 3 so as to make it possible to suspend and support the object to be lifted with the wire.SELECTED DRAWING: Figure 1
【課題】吊上げ対象物の重量が極めて大きい場合であっても、吊上げ対象物及びワイヤの傷損が防止され、吊上げ対象物の容易、かつ、安全な吊下げ支持を可能とする溝付きナットを提供すること。【解決手段】ワイヤにより吊下げ支持される吊上げ対象物が有するボルト部に螺合されるナット1であって、ワイヤが巻掛けられたときにワイヤの太さ方向の位置ずれを防止する溝部2が外周に設けられたフランジ部3を有し、ボルト部に螺合され、フランジ部3の溝部2にワイヤが巻掛けられ、ワイヤによる吊上げ対象物の吊下げ支持を可能とすることを特徴とする溝付きナット。【選択図】図1
