The invention relates to a device for conveying travelable bodies which are provided no driving source, on a fixed path. A plurality of travelable bodies can travel on the fixed path while aligned substantially in close contact with each other. Traveling power is transmitted to one of a plurality of travelable bodies which is positioned on at least one end of the alignment. The traveling power drives the travelable body with frictional force while pressing one side surface of the travelable body, and is transmitted to the travelable body while backing up the other side surface of the travelable body. A device to transmit traveling power is arranged on only a part of the fixed path.
