5. The power supply device for a vehicle according to claim 4,

wherein a cooling air passage is formed to send a cooling air to a battery storage space divided by the dividing wall, and

further an air passage opening is formed at the outer surface, and is connected to the cooling air passage with consecutive space.

6. The power supply device for a vehicle according to claim 1,

wherein each of the nickel hydride batteries has a cylindrical outer case, and a covering portion having a curved surface along surfaces of the plurality of the cylindrical nickel hydride batteries is formed in the storage case.

7. The power supply device for a vehicle according to any claim 1,

wherein each of the nickel hydride batteries is held in a horizontal posture in the storage case.

8. The power supply device for a vehicle according to claim 1,

wherein the power supply device is capable of being installed in a vehicle having idling stop function, and both of the lead-acid battery and the power supply device are capable of being charged with power of regenerative power generation of the vehicle.

9. A vehicle having the power supply device according to claim 5, comprising:

an engine for driving;

a radiator for cooling the engine for driving; and

a cooling fan for forcibly blowing air to the radiator,

wherein the cooling air passage is disposed in an air passage of the cooling fan.

10. A vehicle having the power supply device according to claim 1, comprising:

an engine for driving; and

an alternator driven by the engine, or a regenerative braking of the vehicle,

wherein the power supply device is charged by the alternator at the regenerative braking, and the vehicle has idle stop function.
