This connecting portion (see the holding portions 28a and 31a) is attached to and detached from the pin 26 on the rear bumper 7 side. It is configured to be possible.

That is, both holding portions 28a, 3 shown in FIG.
When the pin 26 is held at 1a, the urging means
(For example, a coil spring wound around the pivot 29)
The urging force acts on the holding portion 31a in the pin holding direction (counterclockwise direction in FIG. 5) to hold the pin 26 by the two holding portions 28a and 31a. Allow rotation.

From the holding state shown in FIG.
When the protruding piece 31b is pressed in the unlocking direction (clockwise direction in FIG. 5) against the urging force of the urging means, each lock lever 31 is unlocked around the pivot shaft 29 as shown in FIG. And the pins 26 by the nuclear holding portions 28a and 31a
Is released, so keep this state and
When 7 is moved forward (to the left in the figure), as shown in FIG.
Each element 17, 28, 31 can be removed from the pin 26.

5 to 8, the rear bumper 7
The connection structure between the board 17 and the board 17 is shown on only one side, but the structure on the other side is symmetrical. 3 and 4 schematically show the connection structure. By the way, as shown in FIGS.
Stoppers 32, 33 are fixed to the adjacent portions of the bent portions 16a, 17a of the seventh.

One stopper 32 fixed to the rear end of the bent portion 16a of the front board 16 in the normal state in which the cargo room 6 is closed is integrally provided with a protruding portion 32a projecting rearward from the rear upper side. Similarly, the other stopper 33 fixed to the front end of the bent portion 17a of the rear board 17 in the normal state is integrally formed with a protrusion 33a that projects forward from the lower front portion. .

As shown in FIG. 3, when the front and rear boards 16 and 17 are arranged in a straight line via the hinge 18,
The lower surface of the protrusion 32a of the one stopper 32 is in contact with the upper surface of the protrusion 33a of the other stopper 33, so that the respective boards 16 and 17 are arranged in a straight line.

Similarly, when the rear bumper 7 is opened downward as shown in FIG. 9 and the boards 16 and 17 are deployed to the rear of the vehicle body to form a tread, the stoppers 32 and
By the action of 33, the respective boards 16, 17 are prevented from buckling downward through the mounting portion of the hinge 18.

In this embodiment, the connecting portions of the boards 16 and 17 by the hinges 18 are used as shown in FIG.
The support portion 34 is set to the support portion 34 supported by
The arrow 16 in FIG.
2. After the holding of the pins 26 by the holding portions 28a and 31a is released, the rear board 17 is moved to the arrow b in FIG.
It is configured to open and close in the direction so as to open and close the upper part of the luggage compartment 6.

Further, after the front board 16 is folded on the upper surface of the rear board 17 via the hinges 18 from the state shown in FIG. 2, each of the pins 16 of the hinge bracket 25 on the rear bumper 7 is used as a fulcrum. When the boards 16 and 17 are raised, as shown in FIG. 10, these boards 16 and 17 are connected to the front part 7 b of the rear bumper 7 on the vehicle interior side.
Can be folded in the vertical direction (vertical direction), and the upper and lower sides of the luggage floor pan 5 are widely opened, and the upper space of the luggage floor pan 5 is effectively used, as shown by a virtual line in FIG. Large luggage and tall luggage A are easily mounted.

In FIGS. 2, 9 and 10, reference numeral 35 denotes a rubber or synthetic resin protector attached to the rear surface of the rear bumper 7, which is opened when the rear bumper 7 is opened rearward and downward as shown in FIG. This is for protecting the rear bumper 7. 2 and 10, reference numeral 36 denotes a lock mechanism.

In the rear body structure of the vehicle configured as described above, a wheelchair or other luggage (mountain bike, small bicycle, or other luggage) can be loaded or moved into the vehicle by first moving the lift gate 8 from the state shown in FIG. The board 1 is pivoted upward and then the rear bumper 7 is pivoted downward and rearward with the pin 19 as a fulcrum, while the board 1 is pivoted with the pin 26 as a fulcrum.
When FIGS. 6 and 17 are deployed to the rear of the vehicle body, they are as shown in FIGS.

That is, as shown in FIG.
The rear protector 35 contacts the road surface, and the rear end portion of the board 16 when the board 16 is deployed contacts the road surface. The rear bumper 7, the board 17, 16 are laid over a gentle slope.

Therefore, using the boards 16 and 17 and the slopes of the rear bumper 7 formed as treads by deployment, wheelchairs B and other luggage with casters, mountain bikes, small bicycles and other luggage shown by virtual lines in FIG. Can be easily entered or transferred onto the luggage floor pan 5. At this time, the lower surfaces of the boards 16 and 17 that have closed the luggage compartment 6 become upper surfaces at the time of deployment, so that when the wheelchair B enters from outside the vehicle, the upper surfaces of the boards 16 and 17 at the time of deployment are Even if mud or sand adheres, when the luggage compartment 6 is covered with the boards 16 and 17, the adhered surface of the mud or sand is located on the lower surface side when the luggage compartment 6 is closed. Disappears.

According to the rear body structure of the vehicle constructed as described above, the rear bumper 7 which can be opened and closed downwardly adjacent to the luggage compartment 6, and the luggage compartment cover plates (boards 16 and 17) which cover the luggage compartment 6
When the rear bumper 7 is opened downward,
One end of the luggage compartment cover plate (see boards 16 and 17) is deployed to the rear of the vehicle body to form a tread plate.
6 and 17) and the rear bumper 7 are rotatably mounted, so that when the luggage compartment 6 is provided with a luggage compartment cover plate (see the boards 16 and 17), a load independent of the vehicle compartment is provided at the rear of the vehicle. A chamber 6 can be formed.

The rear bumper 7 is opened rearward and downward, and the luggage compartment cover plate rotatably attached to the rear bumper 7 is opened.
When one end of each of the boards (see boards 16 and 17) is extended to the rear of the vehicle body to form a tread as shown in FIG.
(Mountain bikes, small bicycles and other luggage) can be easily loaded or transferred into the vehicle.

Moreover, both of them (easiness of formation and transfer operation of the cargo room 6) can be compatible with a simple structure and the number of small parts, and the cargo room 6 is further provided with a cargo room cover plate (board 16). , 17) has the effect of improving the usability of the luggage compartment 6 and improving the appearance.

Further, a plurality of plate members (boards 16 and 17)
(See Reference) to form the above-mentioned luggage compartment cover plate,
For what constitutes the luggage compartment cover plate with a single plate member,
There is an effect that a free form can be ensured according to the use mode of the luggage compartment 6.

In addition, the above-mentioned luggage compartment cover plate (board 1)
6 and 17) includes a support portion 34 (see FIG. 2) supported by the vehicle body (see the board mounting portion 11). , The lower part of the luggage compartment cover plate (see boards 16 and 17) is set as the lower luggage compartment (duty luggage compartment), and the upper part of the luggage compartment cover plate (see boards 16 and 17) is set as the upper luggage compartment. Room
(Clean luggage compartment), and the luggage compartment cover plate (board 16, 1
7) has the effect that the luggage can be stored in and taken out of the lower luggage compartment (see luggage compartment 6).
