As shown in FIG. 1, an extension portion 5 having a bellows-shaped hood 10 is provided between the rear unit 2 and the vehicle body 1, and when the rear unit 2 is extended, the extension portion 5 between the vehicle body 1 and the rear unit 2 is provided. The spaces are connected by an extended hood 10. Hood 10
Is made of a durable waterproof cloth or a flexible synthetic resin so that it can be expanded and contracted. For this reason, the luggage compartment 1b at the rear of the vehicle body 1 is greatly extended rearward and is shielded from the outside.

An auxiliary tire 8 which is a supporting means is provided below the rear unit 2, and the auxiliary unit 8 supports the rear unit 2 and the extension portion 5 at a predetermined height. A rear grip 7 projecting to the outside is provided at a strong portion just above the bumper at the lower rear surface of the rear unit 2. The rear grip 7 is a manual operation handle for separating the rear unit 2 from the vehicle body 1 and extending the luggage compartment 1b. The light van of the present embodiment may be configured such that the rear unit 2 can be extended to a predetermined position by electric drive to extend the luggage compartment 1b.

FIG. 2 is a side view showing a partially cutaway view of the vehicle with a rear extension function of the present embodiment, showing a state in which the rear unit 2 is extended and the luggage compartment 1b is enlarged. . FIG. 3 is a plan sectional view taken along the line IV-IV of the automobile with the rear extension function shown in FIG. 2 and 3, the extension portion 5 having the hood 10 includes a slide floor 3 that slides in the floor portion of the vehicle body 1 and has its rear end fixed to the rear unit 2, and slides provided on both sides of the slide floor 3. The floor 3 includes a folding grid portion 4 in a lattice shape that expands and contracts according to the sliding movement of the floor 3. Slide floor 3
Is a thin plate-shaped iron plate reinforced by the frame 3a fixed to the lower surface thereof. When the rear unit 2 is mounted and fixed to the vehicle body 1, the slide floor 3 is
It is stored inside a storage hole 30a formed inside the floor portion 30 of the vehicle body 1. The slide floor 3 constitutes a floor surface of the luggage compartment 1b which is drawn out from the storage hole 30a under the floor plate of the vehicle body 1 by the extension operation of the rear unit 2 and extended.

Although the slide floor 3 in the present embodiment is formed in a flat plate shape, the cross section may be formed in a rectangular corrugated shape to further enhance its rigidity. As shown in FIG. 2, the rear unit 2 is provided with a flip-up type back door 6 to facilitate the entry and exit of luggage and people from the luggage compartment 1b.
