Abstract: PROBLEM TO BE SOLVED: To enable the use of an air conditioner without running an engine during parking by providing a power feeding socket, feeder line attachment/ detachment detecting means and power feeding switch control means or the like. SOLUTION: The ON/OFF of a power feeding switch 9 is controlled based on a signal from a sensor 15 as the feeder line attachment/detachment detecting means for detecting whether an external feeder line is connected to a power feeding socket 12 or not. While the power feeding switch 9 is turned on and power is used, a power charge is calculated corresponding to the used power from power quantity 10 and displayed and in addition to a parking charge, the power charge is automatically settled from a card or coins. Thus, even when the engine is stopped during parking, the on-vehicle cooler or heater can be used by feeding power from a parking meter 1.
