PROBLEM TO BE SOLVED: To provide a power supply device capable of improving assembly working efficiency by extremely lessening mounting processes by bolts or the like, in assembling of the power supply device in which cell modules are stacked in a thickness direction.SOLUTION: A top-side receiving surface 11a (a concave surface) in a concave shape downward from the top so as to receive a restraining rod 14 from above is formed on a top surface of each cell module 11, and the top-side receiving surface 11a and an outer periphery surface of the restraining rod 14 are attached firmly through a rubber member 15 (an elastic member) in a compressed state. Therefore, as the concave shape of the top-side receiving surface 11a and a convex shape of the outer periphery surface of the restraining rod 14 are fitted each other, each cell module 11 is fixed in movement with respect to the restraining rod 14 in a direction orthogonal to an arrangement direction of the cell modules 11. |
