Further, a handle 16 is integrally formed on the upper end of the back plate 10, and a folding prevention structure 17 is provided on the folding shaft 11 portion to prevent the back plate 10 from bending and maintain the open state. ing.

As shown in FIGS. 3 and 4, this bending prevention locking structure 17 includes a side groove 171 of the upper plate member 12 and a side groove 172 of the lower plate member that are continuous vertically when the back plate 10 is in the open state. It is formed by a locking piece 173 inserted into the upper plate member side groove 171 and a spring 174 that biases the locking piece 173 downward, and when the 11i-plate 10 is opened, the locking piece 173 is The lower end portion falls into the F plate member side groove 172, thereby maintaining the back plate 1° open state.

Note that this locking piece 173 is connected to the hook portion 17 provided at the upper end.
5 protrudes to the outside from a through hole 176 provided in the upper plate member 12, and can be moved up and down by this hook 175.

The loading platform 20 is a plate-shaped member having a concave portion 21 on the upper surface in which a load is placed, and is rotatably supported by a shaft at the lower end of the back plate 10, so that the loading platform 20 can be rotated between the back plate LO and the movable state. It is foldable.

The rotating shaft 22 of this loading platform 20 is provided at the lower end position of the four parts 15 on the lower member 13 side, and the loading platform 20 is stored in the lower plate member side recess 15 in a folded state.

Further, at the tip of the loading platform 20, a standing leg piece 23 is rotatable iif.
The loading platform 20 can be maintained in a horizontal state by standing the standing leg piece 23.

The left and right wheels of the heavy wheel 30 are connected by an axle 31, and the axle 31 is rotatably supported by a bearing portion 19 at the lower end of the back plate 10, and the outer surface of the wheel 30 is connected to the side surface of the back plate 10. They are arranged so that they are on the same plane.

As shown in FIG. 5, the width of the wheel 30 can be adjusted by expanding and contracting the axle 31, and when in use, the width of the vehicle can be increased to improve the stability of cargo.

Further, at the upper end position of the back plate 10 where the wheels 30 are arranged when the back plate 10 is folded, circular cases 50 for storing the wheels 30 are provided on the left and right sides, and furthermore, left and right cases 50. Between 50 and 50 is a groove 18 for storing the axle 31.
is formed.

Note that the case 50 is divided into two semicircular parts that can be opened and closed.
It is made up of parts.

The storage bag 40 is made of cloth that can be folded into a small size and is usable. When not in use, it is stored in the four parts 21 of the loading platform 20 in a folded state, as shown in FIG. 3, and when in use, as shown in FIG. 6. It is attached to the back plate 10 as shown in FIG.

Next, the operation of this embodiment will be explained.

When folding the handcart when not in use, the loading platform 20 is first folded and stored in the recess 15 on the lower member 13 side of the back plate 10. At this time, the standing leg piece 23 is also rotated so as to be disposed on the same plane as the loading platform 20 and stored in the recess 15.
