RESTRAINT JIG OF POWER STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a restraint jig of a power storage device capable of simply performing restraint work in which variation of a load applied to a case is suppressed.SOLUTION: A restricting jig 30 of a secondary battery 10 includes: a restraint plate 31 arranged in the outside of each long side wall 12d; and a bolt 32 and a nut 33 which couple a pair of restraint plates 31 in the lamination direction. The restraint plate 31 includes: a contact surface 31b which comes into contact with the outer surface of the long side wall 12d; a reference surface 31c which aligns with the outer surface of a bottom wall ; and a relief part 35 which separates the corner 12g of a case 11 and the restraint plate 31 from each other in a state where the relief part is more recessed than the contact surface 31b in the thickness direction of the restraint plate 31, and the outer surface of the bottom wall and the reference surface 31c are aligned with each other.
