PROBLEM TO BE SOLVED: To provide a lifting attachment capable of easily suspending an object to be held without utilizing the peripheral edge part of the object to be held. SOLUTION: A body 1 is inserted in the engaging hole of an object to be held with a protrusion part 16a of an handle member 16 not locked in a groove 8a of a column part 8.When a tang member 11 passes an engaging hole, the handle member 16 and a rod member 15 are slid upward by the energizing force of a spring 18, a tang member 13 is revolved to a protrusion position B, and an engaging surface 13 is engaged with the peripheral part of the engaging hole of the object to be held, and the lifting attachment is attached to the object to be held. Meanwhile, when, in this state, the handle member 1 is pressed downward, the tang member 11 is positioned in a containing position A and the handle member 16 is rotated such that the torsion of the spring 18 is dissolved, and the protrusion part 16a is locked in the groove 8a. This holds the containment position A of the tang member 11 and allows the lifting attachment to be removed from the object to be held. COPYRIGHT: (C)2004,JPO
