PROBLEM TO BE SOLVED: To provide a car for the tire replacement work in which no problems attributable to the power supply including the adverse effect on the tire replacement work by the vibration occur. SOLUTION: While a car is traveling, an alternator 21 is driven by the rotation of an engine, and the generated power is charged in a working battery 22. During the tire replacement work, the engine is stopped, the 12V DC current of the working battery 22 is supplied to a first inverter 23, and converted into the 100V single phase AC current. The converted AC current is further converted into the 200V three-phase AC current by a second inverter 24, and supplied to a tire changer 12. Vibration generation during the tire replacement work is prevented thereby, and the balance adjusting work by a wheel balancer 13 sensible to the vibration can be performed with high accuracy and in a short time. Since neither noise nor exhaust gas is generated, this system is environment-friendly. COPYRIGHT: (C)2005,JPO&NCIPI
