The amount of rotation with respect to the cylinder 11 is limited to approximately 180 degrees.

The first lock member 14 restricts the rotation of the support column 15 by engaging with a second lock member 17 provided on one side thereof, and as shown in FIGS. Is provided coaxially with the fixed cylinder 11 and the rotary cylinder 13, and the engaging projection 14 that protrudes in the axial direction is provided on the outer peripheral portion.
A large number of a are formed over the entire circumference (in FIG. 3, only a part is shown and the rest is omitted).

As shown in FIG. 6, the pillar 15 is formed to have a length such that the upper ends thereof substantially coincide with the upper ends of the side gate C and the rear gate D in the upright state, and the pillar 15 is fixed for fixing the side gate C. The means 15a and the fixing means 15b for fixing the rear gate D are provided.

The second lock member 17 is a disc as shown in FIG. 4, is provided coaxially with the fixed cylinder 11 and the rotary cylinder 13, and has an outer peripheral portion that projects in the axial direction. A large number of fitting recesses 17a are formed over the entire circumference (in FIG. 4, only a part is shown and the rest is not shown). The second lock member 17 is fixed to a cylindrical holder 18 having a square cross section, which is supported by the bracket 12 so as not to be rotatable but axially movable, and engages with the first lock member 14 by axial movement. It is supposed to leave. In addition,
The ring 19 fixed to the holder 18 together with the second lock member 17 is a guide for ensuring that the holder 18 can be smoothly moved in the axial direction.

The holder 18 is biased by a spring 20 provided therein via a pin 21 in the right direction of FIG. 1, that is, in a direction in which the second lock member 17 engages with the first lock member 14, and a release lever 22. It is pushed to the left in FIG.

The release lever 22 is attached to the bracket 1 by the support pin 23.
2, which is tiltably supported by the long hole 2 provided at the swing end.
It is fitted to a pin 21 penetrating the holder 18 at 2a.

Further, in this embodiment, the lock plate 24 is rotatably attached to the bracket 12 and the release plate 25 is fixed to the rotary cylinder 13. The lock plate 24 is provided with a notch 22 provided at the swing end of the release lever 22.
In addition to a lock pin 24a engageable with b, a bent portion 24b engageable with the release plate 25 is provided, and the support 15 is provided with the release lever 22 being rotated.
When the lock pin 24a is rotated downward to become as shown in FIGS. 5 and 7, the lock pin 24a is rotated downward by the spring S provided between the brackets 12 and the release lever 22.
The release lever 22 is held in a rotating state by engaging with the notch 22b of FIG. 5, and the support column 15 in the state shown in FIGS. 5 and 7 is shown in FIGS. When it is returned to the state shown in FIG. 6, it is pushed by the release plate 25 and rotated upward to release the engagement between the lock pin 24a and the notch 22b of the release lever 22.

In the present embodiment configured as described above, the release lever 22 in the state shown in FIGS. 1 and 2 is rotated to move the holder 18 and the second lock member 17 against the spring 20. Then, since the second lock member 17 is disengaged from the first lock member 14 and the support column 15 is rotatable, in this state, the support column 15 standing above the loading platform B is tilted down to below the loading platform B. It is possible to retreat, or to raise the support column 15 that is retracted below the cargo bed B to stand above the cargo bed B.

Therefore, when the state shown in FIG. 6 is changed to the state shown in FIG. 7 (when the side gate C and the rear gate D are opened), the support column 15, the side gate C, and the rear gate D are provided.
The work is very similar to the conventional work such as releasing the fixing of each of the side gates C and the rear gate D and opening the side gate C and the rear gate D respectively, and the conventional work of rotating the release lever 22 to rotate the column 15 downward. Open the side gate C and rear gate D by a simple operation, and
Can be retracted below the loading platform B. In this state (retracted state), the release lever 22, the second lock member 17, etc. are held by the lock plate 24 in the state shown in FIG.

Extremely simple work such as rotating the
The lock plate 24 is pushed and rotated upward by the release plate 25 immediately before the stand upright. Therefore, when the lock pin 24a is disengaged from the notch 22b of the release lever 22 and the column 15 stands up, the release lever is operated by the spring 20. 22, the second lock member 17 and the like return to the state of FIG. 1, and the support 15 is held in the upright state by the cooperative action of both lock members 14 and 17, and the side gate C and the rear gate D are closed. The side gate C and the rear gate D can be closed by a work similar to the conventional one such as fixing the pillar 15 to the side gate C and the rear gate D, respectively.

In the above embodiment, when the lock plate 24 and the release plate 25 are provided and the side gate C and the rear gate D are closed, the pillar 15 is simply rotated upward without operating the release lever 22. Although 15 can be automatically held in the upright state, the present invention can be implemented without providing the lock plate 24 and the release plate 25. In such a case, the release lever 22 must be operated even when the side gate C and the rear gate D are closed, but still, the side gate C and the rear gate D can be closed by an extremely simple work as compared with the conventional work. You can

In addition, in the above-described embodiment, the pillar 15 is attached to the side gate C.
The present invention has been implemented by mounting it on the side, but the strut is mounted on the side of the rear gate (in FIGS. 6 and 7, the gate indicated by reference numeral C is a rear gate, and the gate indicated by reference numeral D is a side gate). The present invention can be implemented in a configuration understood by assuming that
