PURPOSE:To uniformly fasten cells by rotationally moving all bolts including a fastening bolt at the center for additional fastening even in states where plural cell blocks are layered. CONSTITUTION:A cell block 1 into which plural unit cells are layer is placed between upper and lower fastening plates 2, 3 and fastened with fastening bolts 4, 5 penetrating the upper and lower fastening plates 2, 3. A bevel 71 is mounted at either one end or both ends of the fastening bolt 5 arranged at the center, and a shaft 6 which has a bevel gear 72 meshed with the bevel gear 71 at one end is extended to the direction perpendicular to the layer direction of the cell block 1. A manual-operation handle 8 or a rotation driving source 8' such as a motor and a rotary actuator is connected to the extension from the fastening plate 2 outward. The handle 8 is rotated or the rotation driving source 8' is actuated to rotationally move the fastening bolt 5 at the center via the shaft 6 and the bevel gears 71, 72 rotated for additional fastening. |
