[0061]

Since the present invention is constructed as described above, as an effect of claim 1, since the bearing cylinder and the base portion of the handle are provided with the anti-rotation mechanism for fixing the anti-rotation state by the elastic pressure mechanism, the normal state is achieved by this mechanism. The left and right handles are firmly fixed to the front in a non-rotatable state, the carrier is moved while pulling the handles, and when not in use, the handles are fixed rearward to reduce the length of the carrier. Since it can be stored as a storage car, it becomes a space-saving carrier.

The effect of claim 2 is that, in the normal state, the left and right handles can be firmly connected and fixed by the connecting handle, so that even on a bad road or a mountain road, the carrier can enter between the left and right handles and place his waist. You can put it in and move it while pulling the handle.

When not in use, the connecting handle is removed from the left and right handles, and the left and right handles are turned rearward by the elastic force mechanism and the rotation stop mechanism to reduce the length of the carrier in the longitudinal direction. Can be stored.

According to the effect of claim 3, since the vertical rails at the center and the left and right vertical rails of the trolley are deployed and held in a flat plate state when used, luggage is loaded on this trolley and is carried while pulling the pulling handle. .

When not in use, the carriage a is folded in half in a vertical direction to reduce the length of the carrier in the width direction, and then the handle is rotated in the rearward direction and fixed in the same manner as above to fix the length of the carrier. Since it can be stored by reducing the length in the direction, it becomes a truck that does not occupy the same space as above.

The effect of claim 4 will be described.

In the normal state, since the central vertical rail and the left and right vertical rails of the bogie are unfolded and held in a flat flat plate normal state by the left and right dividing horizontal rails, this bogie is loaded and conveyed while pulling the pulling handle. .

When not in use, the left and right dividing crosspieces are rotated to fold the carriage in half lengthwise, and the length of the carriage in the width direction can be reduced and stored, so that the carriage becomes a space-saving carrier.
