造が採られている。(Prior Art) Generally, in a conveyor frame, side frames on both sides that support the shafts of rollers and pulleys are connected at predetermined intervals via a plurality of cross-joint frames. As described in Japanese Utility Model Publication No. 56-8810, a structure is adopted in which end plates are welded to both ends of the horizontal joint frame, and the end plates are fastened and fixed to the side frame with bolts.

る。 In this conventional structure, the end plates are fixed by welding to the end faces of round pipes, round bars, etc. that have been cut to a predetermined length, holes are drilled to insert bolts into the end plates, and the holes are then internally threaded. It is necessary to do this work, which takes time to manufacture.Furthermore, if the manufacturing precision of this horizontal joint frame is poor, the parallelism of the frame will not be achieved.
There is a problem in that the left and right frames tend to be misaligned.

両側縁に円弧状の係合部２を形成し、コンベヤの
両側の側枠を締着する長いボルトを係合部２に抱
き込むように係合する構造が提案された。 Therefore, as shown in FIG. 4, the horizontal joint frame 1 is shaped to be inclined downward from the center toward both sides.
A structure has been proposed in which arc-shaped engaging portions 2 are formed on both side edges, and long bolts that fasten the side frames on both sides of the conveyor are engaged so as to be held in the engaging portions 2.

ボルトが係合部２内に安定しないため、この作業
が面倒である問題があつた。(Problems to be solved by the invention) However, in the case of the above-mentioned conventional horizontal joint frame 1, overload is applied or the frame is stepped on,
If it deforms into a flat shape, there is a problem that the engaging part 2 will come off the bolt, and when assembling the conveyor frame, the horizontal joint frame 1 may be inserted through the mounting hole of one side frame.
It is necessary to align and insert the long bolt engaged with the engaging part 2 of the side frame into the mounting hole of the other side frame.
There was a problem in that this work was troublesome because the bolt was not stable within the engaging portion 2.

本考案は、このような問題点に鑑みなされたも
