PROBLEM TO BE SOLVED: To enable loading and unloading relatively easily and with light force by only attaching an attachment having a simple structure and low cost to agricultural machinery, and also enable self-propelling.SOLUTION: A structure is mounted in agricultural machinery and has a horizontal bar in an upper end. In the structure, a horizontal axial rod is attached at a front side from a pair of L-shaped components, a roller is attached in the tip lower part of a support bar turning with this axial rod as a fulcrum, and the tip of a connection bar can be connected in the middle of the support bar, and therefore, the structure is simple and this inexpensive attachment is enough just to be attached to the agricultural machinery, and it is not necessary that the supporting leg of a bridge where the agricultural machinery passes falls down and the bridge is extended to make a slope slow, and is secured at low cost. Furthermore, self-propelling is possible by just lowering the support bar.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2017,JPO&INPIT【課題】構造が簡易で安価なアタッチメントを農機具に取付けるだけで、比較的容易に軽い力で積み降ろし可能とし、自走も可能とする。 【解決手段】農機具に取付けられ、上端に水平バーを有する構造において、一対のL字状部材より前側に水平の軸棒が付いており、この軸棒を支点にして回動する支持バーの先端下部にローラを付けてあり、連結バーの先端を前記支持バーの中間に連結可能としてあるので、構造が簡易であり、この安価なアタッチメントを農機具に取付けるだけで足り、農機具が通るブリッジの支持脚が倒れたり、スロープを緩くするためにブリッジを長くしたりする必用も無く、無難で安価である。しかも、支持バーを下向きにするだけで自走も可能である。【選択図】図5
