<P>PROBLEM TO BE SOLVED: To suppress deterioration in a capacitor unit for a carrying vehicle for driving a tire not only by an engine, but also by the capacitor unit. <P>SOLUTION: There are provided the tire 2, the engine 3 and a motor 4 for driving the tire 2, the capacitor unit 5 connected to a feeding path to the motor 4, and a battery 6 connected to a charge path to the capacitor unit 5. The capacitor unit 5 comprises a case 11, at least one capacitor element 12 stored in the case 11, a temperature sensor 13 for detecting temperature inside the case 11, and first and second blowers 14, 15 for cooling inside the case 11. When the temperature detected by the temperature sensor 13 is lower than set temperature, the first blower 14 is driven. When the temperature detected by the temperature sensor 13 becomes higher than the set temperature, the first and second blowers 14, 15 are driven. <P>COPYRIGHT: (C)2007,JPO&INPIT |
