To ensure that an energy supply operation can be performed safely and smoothly on a vehicle having a plurality of energy ports such as a charging port, charging ports for supplying electric energy to a high voltage battery and a fuel supply port for supplying fuel to a fuel tank are provided in a vehicle body as energy supply ports. The fuel supply port and charging ports are respectively provided with lid members that are switched between a closed state and an open state by respective lock mechanisms. When closure of one lid member is released, all of the other lid members are prohibited from being switched to the open state, and therefore the number of energy supply ports having an open lid member is limited to one.
