For example, the clamp portion of the connecting body is fixed at a predetermined position on the pole, and the clamp portion is fixed with a fastener. By this operation, the connecting member is fixed to the pole, and the bent portion of the fixed connecting member is inserted into the mounting portion of the prism. Therefore, the connecting body is interposed between the prism and the pole. This operation and procedure are repeated, and a large number of connected bodies are interposed between the prism and the pole, so that the prism is attached to the pole via each connected body.

Subsequently, an elevating lifter comprising a back portion and a receiving portion is provided on the prism. The lifter is moved up and down by driving the elevator using the prism as a guide. Since the lifting lifter is lifted and lowered by a loosely fitting configuration of the prism and the support frame, the lifter is raised and lowered in a stable state without lateral swing. The assembling and disassembling (removing means) of the back portion of the lifting / lowering lifter and the load receiving portion will be described. In the example of FIG. 4, the attached piece at the back portion is locked to the mounting piece of the load receiving portion.
The hook hole of the mounting piece is locked to the mounted piece, and the load receiving portion is mounted on the back. By this series of operations, the load receiving portion is fixed to the back in a substantially L-shape when viewed from the side. Removal of the load receiving portion can be easily performed by an operation of detaching the mounting piece from the mounted piece. Incidentally, there is an example in which a stay is used as shown in FIG. Next, in the example of FIG. 5, a configuration example in which a side frame is provided in the load receiving portion is shown. 6 and 7 show an example in which the size of the receiving portion is reduced. The structure is almost the same as the above-mentioned example.

Incidentally, the assembling and disassembling structure of the back portion and the receiving portion is not limited to the above-described example. Therefore, although not shown, the following configuration may be used. That is, the mounting ring of the load receiving portion is aligned (matched) with the mounted ring on the back, and the aligned mounted ring and the mounting ring are pivotally supported via the pivot. Since the mounting ring and the mounted ring are aligned substantially in a straight line as described above, the mounting ring and the mounted ring are aligned with each other. The load receiving portion is attached to the back by a series of operations such as locking the stopper. In order to remove the receiving part, the pivot must be removed. Thereafter, the attachment ring can be easily detached from the attached ring. As another example, in a configuration in which the receiving portion is swingable, the receiving portion is swung, the receiving portion is attached to the back portion, and the receiving portion is fixed to the back portion. By this operation, the swing of the load receiving portion and the fixed state of the swing position are ensured. Further, in a configuration in which the receiving part can be expanded and folded, the same use as a normal receiving part can be achieved in the folded state. It is also useful for carrying large or bulky luggage in the unfolded state. Of course, also in this example, it is possible to make the receiving section detachable.

The above usage modes, operations and procedures, assembling, and the like are merely examples, and are within the scope of the present invention as long as similar usage modes and the like are followed.
