PURPOSE: To make the whole of a loading device light and compact by moving a carrying base singly in a fixed section and through a driving means with a movable frame in another section to reduce the moving distance of the carrying base to about one half of a distance required for load feeding.

CONSTITUTION: A carrying base 5 is pulled by a driving means to make an endless belt 19 rollingly move, and thereby moved before and behind on a movable frame 6. In this case, the carrying case 5 moves singly in a section equivalent to about one half of the movable frame 6 and with the movable frame 6 in a remaining section. In a working cycle, a moving distance of the carrying base 5 which is moved by the endless belt 19 being in charge of both carrying and travelling is satisfied by about one half of the whole of load feed distance. Thus a loading device can be formed to be wholly light and compact.
