Abstract
A power supply device disposes an end plate at each end of a battery stack in a stacked direction of the battery stack, and couples a binding bar to the end plate, so as to fix battery cells. The binding bar includes a plate-shaped bar that extends in the stacked direction, and an engagement block that is provided on a plate-shaped bar and protrudes toward an outer peripheral face of the end plate. The engagement block is inserted into a fixing hole provided in the plate-shaped bar and fixed to an inner peripheral face of the fixing hole. The end plate includes a fitting part, to which the engagement block is guided, on the outer peripheral face of the end plate, and includes a stopper that is disposed closer to the battery stack with respect to the fitting part and abuts the engagement block.
