Attachment: The upper end of an arm 3 of a required length is attached to one end of the arm mount 2 so that it can rotate up and down, and the stopper member of the spring assembly m (having a horizontally angular shape) is attached to the lower end of the arm 3. Horizontal receiving plate 3a for supporting
A spring 7 is disposed between the arm 3 and the mounting base 2 to constantly urge the arm 3 to rotate toward the spanner body 1 side, and an operating wire 9 is connected to the upper end of the arm 3. Further, a spring assembly for a nuclear fuel assembly is provided, in which an abutment plate 10 is attached to the arm mount 2, which extends on the opposite side of the arm 3 and regulates the posture of the mount 2 and the arm 3 with respect to the fuel assembly. removal device.
