Base plate mounting bar 13 having both ends fixed by welding or the like
It is composed of

Reference numeral 14 is a base plate mounting bar 1 of the fixed shelf frame 9.
3 is a base plate that covers the upper part of the bogie frame 1 rotatably attached to the carriage 3.

Reference numeral 15 denotes a movable shelf frame attached to the shelf frame supporting members 7, 7 at the front end of the bogie frame 1. The movable shelf frame 15 has its lower end portion slid vertically on the shelf frame supporting member 7 by a predetermined amount. A rear movable support column 16 movably mounted, and an inverted L-shaped front movable support column 1 in which a lower end portion welded and fixed to an upper end portion of the rear movable support column 16 is locked to the shelf frame support member 7.
7, and a plurality of, in the present embodiment, five shelf support bars 18 at predetermined intervals between the front movable column 17 and the rear movable column 16.

Reference numeral 19 denotes the upper end of the rear column 10 of the fixed shelf frame 9 and the upper end of the rear movable column 16 of the movable shelf frame 15, both ends of which are rotatably movable. It is a reinforcing bar.

The carrying cart 20 having the above-mentioned structure is loaded with the luggage 21 stored in a cardboard box on the base plate 14, and is moved by pushing or pulling while holding the fixed frame shelf 9 or the movable shelf frame 15. .

At this time, the fixed wheel 5 in the substantially central portion of the bogie frame 1 facilitates straight movement, and when rotating, the fixed wheel 5 serves as a fulcrum and can be easily rotated.

When not in use, the base plate 14 is rotated to be supported by the fixed shelf frame 9, and the movable shelf frame 15 is slid upward so that the lower end portion of the front movable support column 17 and the shelf frame support member 7 are separated from each other. The engagement is released, and it is rotated and positioned on the rear side bar 2a.

In this state, by pushing the front end portion of the carrying carriage 20 to be stored and stored behind the carrying carriage 20 stored at the storage position, nesting can be performed as shown in FIG.
