Accordingly, the regulation member 24 tends to be pulled and moved. As the restriction member 24 is pulled and moved, the engaging portion 26 pushes the next locking claw 25 against the component force so as to rotate the restricting member 24 around the rotation axis X2, and the engaging portion 26 moves to the next position. By passing over the locking claw 25, the restricting member 24 is pulled and moved, that is, the swinging of the tension sprocket 16 in the tension applying direction is allowed, and the next locking claw 25 is engaged with the engaging portion 26. Movement of the regulating member 24 in the direction opposite to the tension applying direction by the force of the spring 17, that is, swinging of the tension sprocket 16 in the direction opposite to the tension applying direction is prevented, and tension is applied to the pull-up chain 11. Then, the tension of the raising chain 11 becomes the set value.

It may be done. In this case, the regulating member 24 is pulled by a tension spring so that the swinging force in the direction in which the locking claw 25 engages with the engaging portion 26 acts on the regulating member 24 around the rotation axis X2 as a component force. . In addition,
The spring 17 is stretched between the tip of the regulating member 24 and the fixed spring receiver 21. As a result, the same effect as that of the above embodiment can be obtained.
