The present invention provides a vehicle-used power storage device, and an object of the invention is to prevent damage to cables of the power storage device when a vehicle receives a back collision. A package battery (12) mounted at the rear body of the vehicle includes: a battery module (20); a PCU (23) connected with the battery module (20); a front holding component (15) and a rear holding component (16) which clamp and hold the battery module and the PCU (23) from the front and back sides, respectively; and a cooling fan (27) mounted on the back surface of the rear holding component (16) through a bracket (31). The front and back load that the bracket (31) can withstand is smaller than the front and back load that the rear holding component (16) can withstand, so that if a collision load caused by back collision is applied to the cooling fan (27), the bracket (31) is deformed and absorbs the impact, thereby preventing the rear holding component from deformation. Therefore, relative displacement of the battery module and the PCU (23) can be prevented, and the damage to the cables connecting the battery module and the PCU is thereby prevented. |
