PURPOSE:To adjust the force clamping a stack to uniformly distribute on the whole surface of the stack by placing a plurality of springs between a clamping plate and an end plate, and increasing the resiliency of a spring arranged in the center of the end plate than that of springs arranged in its surroundings. CONSTITUTION:A spring 13a in the center of an end plate has larger resiliency compared with a plurality of springs 13b,...13b arranged in its surroundings. Clamping bolts 15 are passed between four corners of a clamping plate 11 on the base side and four ends of a clamping plate 12 having an X shape on the upper side through spacers 14. By adjusting the nuts 16 at both ends of the clamping bolts 15, the clamping plates 11, 12 are clamped to clamp a stack 10. When the stack 10 is clamped by adjusting the nuts 16, the clamping force is applied to the stack from the clamping plate 12 by the resiliency of springs 13a, 13b,...13b. Therefore, the clamping force is uniformly distributed in a surface direction of the stack 10. |
