To solve the problem of a conventional sling wherein since a damping rubber is fixed to the lower plate of a lower lifting lug, the damping rubber may be damaged and a lower lifting bolt may drop due to the damage.

This sling comprises a first member 2, a second member 3, an elastic body (rubber columnar body 4), and a nut fastening surface body 5. The first member 2 is fitted to an upper lifting bolt. The second member 3 comprises an arm part 15 fitted to the leg part 7 of the first member 2 rotatably around the rotation center axis, a lower plate 80 connecting the lower end parts of the arm part 15 to each other, and an elongated hole 17 formed in the lower plate 80 along the rotation center axis. The elastic body is disposed on the upper surface side of the lower plate 80. The nut fastening surface body 5 is disposed on the lower surface side of the lower plate 80. The nut fastening surface body, the second member, and the elastic body are connected to the lower lifting bolt 26. As the lower lifting bolt is moved in the elongated hole, the nut fastening surface body and the elastic body can be moved along the lower plate.
