2 is the loading platform of the truck, and 2 is a short side plate that can be opened and closed on either side of the loading platform.
上記荷台１上には、荷物の積載の邪魔にならない前後の
位置に柱筒状のフレーム３，３が立設されている。Column-shaped frames 3, 3 are erected on the loading platform 1 at front and rear positions where they do not interfere with the loading of luggage.
柱筒状のフレーム３，３の内部にはコイルスプリング等
の伸縮体４，４が備え付けてある。Inside the cylindrical frames 3, 3, extensible bodies 4, 4 such as coil springs are installed.
以下左右には同じものが備えられているため一方のみ説

しめて或るものである。A support rod 5 is provided on the upper part of an extensible body 4 such as a coil spring provided in a cylindrical frame 3, and a pulley-shaped groove 8 in which a support wire 10 is engaged approximately halfway around the upper part of the support rod 5.
A cam 8 having a substantially plate cam shape provided with a cam 8 and the upper end of one side of the side door 7 of the truck loading box are pivotally connected to the connecting shaft 6, and the connecting shaft 6 supports the ceiling plate 9 of the truck loading box. One end 10' of the wire 10 is inserted into the groove 8' of the cam 8, and the other end 10"
A support wire 10 fixed to the frame is provided to make the structure work.
而して図中符号１１は側扉７に設けられた側扉の開閉ロ
ープである。Reference numeral 11 in the figure is a side door opening/closing rope provided on the side door 7.
尚支持ワイヤー１０の他端１０“は図示の如く柱筒状の
フレーム３に取付金物１２を固着し、該取付金物に枢着
１３構戊せしめておけば作動が円滑である。The other end 10'' of the support wire 10 can be operated smoothly if a mounting hardware 12 is fixed to the cylindrical frame 3 as shown in the figure, and a pivot 13 is attached to the mounting hardware.

を支点として上昇と同時に回転するため同じ連結軸６に
軸着された側扉７は弧を画いて高く開放し、また連結軸
６の上昇に伴って連結軸６に支持された天井板９も高く
押し上げられる。Since the present invention is constructed as described above, when the opening/closing rope 11 provided on the side door 7 is loosened, the support rod 5 rises due to the repulsive force of the extensible body 4 such as a coil spring. The cam 8 that is pivoted at the upper end is pulled by a support wire 10 that has one end fixed to the cam and the other end fixed to the frame, and connects to the connecting shaft 6.
The side door 7, which is pivoted on the same connecting shaft 6, opens high in an arc, and as the connecting shaft 6 rises, the ceiling plate 9, which is supported by the connecting shaft 6, also rotates at the same time as the connecting shaft 6 rises. be pushed high.

持ワイヤー１０に力がかかり連動する連結軸６が下がり
つつ天井板９は側扉７の回転につれて閉止動作が行われ
る。Note that when the opening/closing rope 11 is pulled down, a force is applied to the support wire 10 connected to the cam 8, and the interlocking connecting shaft 6 is lowered, and the ceiling plate 9 is closed as the side door 7 rotates.
本考案は叙上の構或、作用より或るから簡単な開閉操作
