PURPOSE:To facilitate the electricity feeding work and secure safety in the nonfeeding of electricity by installing an electricity feeding collector and a cover for opening/closing the collector on an electricity feeding station side, and installing an on-vehicle collector which contacts the electricity feeding collector on an unmanned transport vehicle side. CONSTITUTION:When electricity is supplied from an electricity feeding station 1 on the ground to an unmanned transport vehicle 7, an operating device 21 on the electricity feeding station 1 side is operated when the unmanned transport vehicle 7 stops on the side part of the electricity feeding station 1, and an electricity feeding device 20 is turned, and pushed outside. At this time, a gear 29a is revolved by a gear 26 fixed on a link 24b through a direct connecting gear shaft 26a, and one cover 30a is-turning opened in the counter-clockwise direction. Further, the gear 29b is revolved in the opposite direction by the gear 29a, and the other cover 30b is turning-opened in the clockwise direction. Accordingly, each electricity feeding collector 32a, 32b is allowed to contact the on-vehicle collector 9a, 9b on the unmanned transport vehicle 7 side, free from trouble. |
