And the fitting concave portion (25) of the upper projecting portion (23) on the side of the second hinge constituting portion (22) are fitted to each other, and are fitted to the rear frame member (11) of the luggage compartment roof portion (3). , Rear door (5)
Has sufficient mounting strength.

Next, as shown in FIG. 2, when the rear door (5) is swung outward with respect to the luggage compartment roof (3), the rear door
(5) swings around the tip of the outward convex portion (26) of the second hinge component (22) of the upper frame member (21). The convex part (2
4) is guided along the guide surface (14a) of the arcuate cross section of the guide portion (14) of the first hinge component (12) on the rear frame member (11) side of the luggage compartment roof (3). And the lower projecting part on the rear frame member (11) side.
The tip of (13) is the upper projection (2) of the second hinge component (22).
In the state after the rear door (5) is opened by 80 to 110 °, the second hinge component (22) is guided along the guide surface (29a) having a circular cross section of the concave portion (29) of (3). The concave portion (29) of the first hinge component (12) is fitted with the inward convex portion (16) at the tip of the downward projecting portion (13), and the outer convex portion of the second hinge component portion (22). The portion (26) and the inward convex portion (16) are engaged with each other, and the second
The tip (23a) of the upper protruding portion (23) of the hinge component (22) is
It is engaged with the lower end of the guide portion (14) of the first hinge component (12). When the rear door (5) is in the most opened state, the rear door (5) is located outside the opening (28) of the upper protrusion (23) of the second hinge component (22) of the upper frame member (21). Edge (35) is the luggage compartment roof
(3) is brought into contact with the rear surface of the rear frame member (11), which serves as a stopper.

Also, since the rear frame member (11) of the luggage compartment roof (3) and the upper frame member (21) of the rear door (5) are made of extruded aluminum, these hinge components (12) are used. ) (22) It is possible to easily perform the fitting work between
(5) The mounting accuracy of (5) can be assured, and the rear door (5)
Can be smoothly opened and closed.

Further, since both the frame members (11) and (21) are made of extruded aluminum material, the weight can be reduced and the rear door (5) mounting portion of the luggage compartment roof (3) can be provided. The appearance is improved.

Further, the hinge components of both frame members (11) and (21)
(12) Since the fitting of (22) is performed over the entire length of the upper edge of the rear door (5), even when the rear door (5) is lifted upward and opened, the load from the hinge portion is not applied. There is no risk of rainwater entering the room (2).

In this embodiment, when the rear door (5) shown in FIG. 1 is closed, it is provided on the upper surface of the eaves (30) of the rear frame member (11) of the luggage compartment roof (3). The sealing material (32) and the drainage projection (30a) having a substantially circular cross section prevent rainwater that flows along the outer surface of the luggage compartment roof (3) from entering the luggage compartment (2). Can be.

Further, when the first hinge component (12) on the luggage compartment roof (3) side and the second hinge component (22) on the rear door (5) side are fitted together, the first hinge component is provided. The upper protrusion (23) of the second hinge component (22) is inserted from below into the recess (19) of (12), and the recess (29) of the upper protrusion (23) opens outward. There is no danger of rainwater entering the luggage compartment (2) from the hinges, and the outer wall (2) of the upper frame member (21) of the rear door (5)
1c) The approximately rectangular cross-section rainwater guide projection (33) at the upper end has its tip directed downward, and the substantially rectangular projection (33)
The body itself also acts as a drain, and serves to keep rainwater flowing along the outer surface of the luggage compartment roof (3) from flowing along the outer surface of the rear door (5).

When the rear door (5) shown in FIG. 2 is open, the rainwater collecting groove (34) provided at the upper end of the outer wall portion (21c) of the upper frame member (21) is closed. An upward opening is provided to receive rainwater flowing down the outer surface of the rear door (5), so that infiltration of rainwater into the luggage compartment (2) can be further eliminated.

In the above embodiment, both the rear frame member (11) of the luggage compartment roof (3) of the truck (1) and the upper frame member (21) of the rear door (5) are made of extruded aluminum material. However, the present invention is not limited to this, and these may be made of other metals or hard synthetic resins.
