The shoe mounting member 108, which has a shoe 98 attached to the lower end and a spring receiver 114 attached to the inside, is slidably fitted into the through hole of the shaft 106, and the tip of the shaft 106 is further bent. The shoe mounting member 108 is prevented from falling off by the retaining plate 110 and the retaining ring attached to the shoe. The shoe mounting member 108 is constantly urged outward by a compression coil spring 112 inserted through the shaft 106 via a spring receiver 114. Therefore, each of the shoes 96 and 98 is located in the guide groove 90 as shown in FIG. 13, and the bogie leg 94 is securely attached to the guide groove 90. The pulling rod 116 projecting from the inside of the shoe mounting member 108 passes through the through hole of the member 102 and projects to the outside, and a nigiri 118 is screwed to the tip end thereof. By pulling the grip 118 outwards against the biasing force of the compression coil spring 112, the distance between the shoes 96, 98 is reduced, and the bogie leg 94 can be easily removed from the guide groove 90. To attach it, reverse the above. Therefore, it is easy to attach and detach the luggage carrier 16 to and from the carrier path 12. Numeral 120 is a collar through which the pull rod 116 is inserted, and regulates the expanded position between the shoes 96 and 98.

In this embodiment, the bogie leg 94 is used as a portion to be guided by the guide groove, and the bogie base 22 with wheels as in the above-mentioned embodiment is not used. Since there is no rotating part like this, there are few malfunctions, and since there are no wheels or the like, there are advantages that it is lightweight and that the luggage carrier 16 is easy to handle. The method of use of this embodiment is the same as that of the above-mentioned embodiment, but when the luggage carrier 16 is attached to or detached from the transportation path 12, the nigiri 118 is operated to move the bogie leg 94 to the guide groove 90. They differ in that they are attached and removed.

In each of the above-mentioned embodiments, the waist wall is used as the transportation path, but instead of this, it is also possible to construct it with a structural material such as an angle material, a channel material, a bar material, a plate material, or a combination thereof. . Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments, and it goes without saying that the present invention can be implemented in various modes without departing from the scope of the present invention. .
