In the above, the tilt side surface portion 1 is assembled as follows.

First, the middle and lower tilt panels 3 and 4 are stacked horizontally, and the male and female fitting portions of their joint surfaces are fitted into each other.

On the other hand, a latching metal fitting 11 having a substantially parallelogram shape when viewed from above is attached to the upper end of each of the required number of connecting bolts 10, and these connecting bolts 10 are attached in advance to the upper end of each of the connecting bolts 10.
It is inserted from above into a through hole 25 formed in each horizontal wall of the panels 3, 4 so as to pass through both the panels 3, 4.

Next, the upper tilt panel 2 is placed near the top of the upper end of the intermediate tilt panel 3, and in this state, each connecting bolt 10 is slightly lifted upward, and the latch 11 of the upper end 10a is With both sides AD and BC aligned with the length direction of the upper tilt panel 2, it is inserted from the lower end opening of this panel 2, that is, between the mutually opposing inner protrusions 8 and 8. (See the dotted chain line in Figure 3).

b is substantially parallel to both side walls 7, 7.

In this state, each latching member 11 is slightly returned downward, so that both ends of the latching member 11 are aligned with the inner protrusions 8, 8.

By fitting and covering the upper end of the middle tilt panel 3 with this upper tilt panel 2, each of the latching metal fittings 1
The lower ends of the hanging walls 11a, 11a of the hanging walls 11a, 11a are fitted into the grooves 6 of the top wall 3a of the intermediate tilt panel 3. It does not rotate by engaging the side walls, so that the connecting bolt 10 no longer rotates at all.

Next, a pair of nuts 13 are screwed into the lower end portion 10b of each connecting bolt 10.

Then, the latch 11 is strongly pulled downward via each connecting bolt 10, and as a result, the lower edges of both side walls 7, 7 of the upper tilt panel 2 are connected to the fitting portion of the upper end of the intermediate tilt panel 3. 5, and the lower end 10b of each connecting bolt 10 is firmly connected to the lower tilt panel 4.

Further, although the upper tilt panel 2 is provided with a hollow portion 12, such a hollow portion 12 may not be provided in some cases.
, 7 and a horizontal wall to form a substantially inverted U-shape in cross section.

Further, although the three tilt panels 2, 3, and 4 constitute the tilt side surface portion 1, the number of tilt panels in combination is of course arbitrary.

Furthermore, although only the side part 1 of the tilt tilt was described, the rear part of the tilt tilt has almost the same structure as the tilt side side part 1, with the only difference being the installation location and mounting of the drain section 24 on the lower edge and the shape of the hinge. are doing.

Further, the lower tilt panel 4 is not limited to the structure of the above embodiment, but may of course have another structure.

The tilt of the truck according to this invention depends on the above,
The upper tilt panel 2 has an opening at its lower end, and a pair of parallel side walls 7 on both sides of this opening.

, 8 are provided facing each other, and a latch 11 is fixed to the upper end 10a of each connecting bolt 10.
1 is made into a substantially parallelogram when viewed from the plane, and at least one of the mutually parallel sides AD and BC is side A.
A hanging wall 11a for preventing rotation is provided in the center of D and BC, and the width P1 of both sides of this latch 11 is made shorter than the interval between the inner protrusions 8, 8 of the upper tilt panel 2. and an intermediate tilt panel in which the distance P2 between the mutually parallel end sides AB and CD is shorter than the distance between the side walls 7, 7 of the same panel 2 and longer than the distance between the inner protrusions 8, 8. 3 is hollow, and a groove 6 is provided in the center of the width of the top wall 3a in the length direction, and each latch 11 is attached to the side walls 7.7 of the upper tilt panel 2. The upper ends 10a of each connecting bolt 10 are placed in the middle and are hooked to the inner protrusions 8, 8, respectively, so that the upper end 10a of each connecting bolt 10 is not hooked to the upper tilt panel 2 via the hook 11. Since they are fastened, the work of hooking and fastening the upper end portions 10a of each connecting bolt 10 to the upper tilt panel 2 can be performed extremely easily.

By fitting and covering the upper end of the middle tilt panel 3 with this upper tilt panel 2, each of the latching metal fittings 1
Since the lower end of the rotation-preventing hanging wall 11a of No. 1 is fitted into the groove 6 of the top wall 3a of the intermediate tilt panel 3, the latch 11 no longer rotates, thereby preventing the upper end of the connecting bolt 10 from rotating. The part 10a can be firmly attached to the upper tilt panel 2 in a non-rotatable state,
All the tilt panels 2.3.4 can be assembled very easily and reliably.

And each latch fitting 11 and the connecting bolt 1 integrated therewith.
0 does not rotate, there is no fear that the connection bolts 10 will loosen due to vibrations while the truck is running.

Moreover, when the upper tilt panel 2 is viewed from its end surface, its both side walls 7, 7 are firmly connected to the upper end of the lower intermediate tilt panel 3 so as to constitute both legs.
Since the upper tilt panel 2 does not have an opening open to the inside of the tilt as in the conventional case, sufficient strength can be obtained.

Therefore, since there is no need to increase the thickness of the upper tilt panel 2 in order to increase its strength, there is an effect that the weight of the tilt panel does not increase.
