PURPOSE:To provide a feed device for automatically charging a battery of an unmanned carrier car which is designed so that no arc is generated at terminals for charging of feeding and receiving sides even if an unexpected accident occurs. CONSTITUTION:A title item is provided with a connection-conformation means such as a contact-type sensor or non-contact-type sensor of a photo sensor etc., which consists of a limit switch 21 and a dog 22 which are placed at an activation distance which is larger than a spacing of each charge terminal of feeding/charging couplers 4 and 3 so that charging terminals 4A, 4B, 3A, and 3B of the feeding coupler 4 and the receiving coupler 3 are placed at a position where they are activated after they contact and performs control so that no charge current is allowed to flow between charge terminals of the feeding coupler 4 and the receiving coupler 3 when operation of this connection- confirmation means cannot be conformed. |
