  Further, the tip 27 of the round hook portion 23 is brought into contact with the inner surface 32 a of the opening in the side plate portion 32. As a result, the tip 27 of the round hook portion 23 contacts the inner surface 32 a of the opening in the side plate portion 32 as an action point (third action point). The acting force vector 19 acting on the third acting point acts on the surface 32a of the side plate portion 32 while being inclined so as to have a component directed upward.

  In this way, different three-direction acting force vectors 17 to 19 act on the first, second and third action points. Therefore, the load applied to the channel member 30 can be dispersed and damage to the channel member 30 can be suppressed.

  When the lifting tool 1 is attached to the channel member 30, the tip 27 (third action point), the rotating shaft 15 (fulcrum), and the force point 25 of the round hook portion 23 are arranged so as not to be aligned. For example, by adjusting the position of the rotating shaft 15 according to the shape of the round hook portion 23, the length of the intermediate portion 21, and the shape of the hanging portion 22, the third action point, the fulcrum point, and the force point 25 are obtained. , Arrange them so that they are not aligned.

  Moreover, it arrange | positions so that the angle | corner which the direction which goes to the power point 25 from the rotating shaft 15 (fulcrum) and a perpendicular downward direction may be 90 degrees or less. For example, by adjusting the position of the rotary shaft 15 according to the shape of the hanging portion 22 and the length of the intermediate portion 21, the angle formed by the direction from the fulcrum to the force point 25 and the vertically downward direction is 90 ° or less. .
