A charging method in a feeder-lineless traffic system in which an electric storage unit of a vehicle running on a predetermined pathway with the use of a power of the electric storage unit mounted on the vehicle is charged from a charger set up on the pathway, wherein a contact charging way in which a power feeder (24, 50) connected to the charger set up on the ground is made into contact with a power receiver (6, 60) mounted on a vehicle is carried out to charge power to the electric storage unit of the vehicle when the vehicle comes to a stop, the power receiver is a planar contactor which is secured to the roof of the vehicle, which is extended in a vehicle advancing direction, having a predetermined thickness, and the power feeder is composed of a pair of feeding shoes each of which is provided to a ground structure arranged each of opposite sides of the planar contactor, through the intermediary of a link mechanism so as to be movable to and from the planar contactor, and means for urging the pair of feeding shoes with a resilient force in a direction in which the pair of feeding shoes approach each other so as to press the feeding shoes against the planar contactor inserted between the pair of feeding shoes, characterized by converting a commercial electric power by the charger and a charge control unit of the charger into a DC power which is chargeable directly into the electric storage unit, and charging the DC power into the electric storage unit through the intermediary of the power feeder (24, 50) and the power receiver (6, 60) while a current value of the DC power is controlled, when the vehicle runs in a running direction and the planar contactor is inserted between the pair of feeding shoes, the vehicle comes to a stop so that the charging to the vehicle is started, or when a return electric cylinder is operated during coming-in of the vehicle so that the pair of feeding shoes are set at a position separated from the planar contactor, and when the planar contactor is inserted between the pair of feeding shoes, the pair of feeding shoes are made into contact with the planar contactor so that the charging to the vehicle is started. a pair of feeding shoes each of which is provided to a ground structure arranged each of opposite sides of the planar contactor, through the intermediary of a link mechanism so as to be movable to and from the planar contactor, and means for urging the pair of feeding shoes with a resilient force in a direction in which the pair of feeding shoes approach each other so as to press the feeding shoes against the planar contactor inserted between the pair of feeding shoes, characterized by converting a commercial electric power by the charger and a charge control unit of the charger into a DC power which is chargeable directly into the electric storage unit, and charging the DC power into the electric storage unit through the intermediary of the power feeder (24, 50) and the power receiver (6, 60) while a current value of the DC power is controlled, when the vehicle runs in a running direction and the planar contactor is inserted between the pair of feeding shoes, the vehicle comes to a stop so that the charging to the vehicle is started, or when a return electric cylinder is operated during coming-in of the vehicle so that the pair of feeding shoes are set at a position separated from the planar contactor, and when the planar contactor is inserted between the pair of feeding shoes, the pair of feeding shoes are made into contact with the planar contactor so that the charging to the vehicle is started.
