Except one side frame support member fixed to the upper and lower portions of one side surface, and the fixed shelf frame detachably attached to the movable shelf frame support formed at the tip of the frame of the truck. A movable shelf frame having a shelf board supporting bar, another side frame support member fixed to a portion of one side surface of the movable shelf frame near the upper and lower parts of the movable shelf frame, and a shelf board supporting bar of the movable shelf frame. Locking pieces provided at both sides of both ends are locked to the shelf support bar of the fixed shelf frame to be used as a shelf board, and the locking pieces at both ends are fixed to one of the fixed shelf frames. Removable from the outside to the side frame support member and the other side frame support member of the movable shelf frame A shelf side frame member that is attached and serves as a side frame, and a suspension that suspends the movable shelf frame and the shelf plate member mounted on either or both of the fixed shelf frame and the movable shelf frame on the fixed shelf frame. Since it is composed of a tool, the shelf board side frame member can be used as a shelf board or as a side frame. Therefore, it can be used for multiple purposes.

(2) According to (1) above, the shelf side frame member can be mounted and removed from the outside, so that the loading port for the loaded luggage can be more efficiently carried out than the front and rear portions.

(3) According to the above (1), the movable shelf frame and the shelf plate side frame member can be stored in a suspended state on the fixed shelf frame when not in use. Therefore, the parts can be easily set in a used state in a short time without being separated.

(4) According to the above (1), the movable shelf frame and the shelf side frame member can be suspended and nested on the fixed shelf frame, so that many can be stored even when the storage space when not in use is small. can do.

(5) According to the second aspect, the same effects as the above (1) to (4) can be obtained, and since one side frame supporting member and the other side frame supporting member do not project outward, clothes etc. It can be effectively prevented from being caught and can be used safely.
