Abstract
A pair of end plates disposed respectively at end faces of a battery stack are connected by bind bars and apply pressure to the battery stack to immobilize the battery stack. Each of the end plates includes a locking hole extending along a surface of the end plate. The end plate is fixed to a base plate by a fixing bolt inserted through the locking hole. The locking hole includes a deformation space that allows deformation of the fixing bolt when cell reaction force of the battery stack is caused.
