PROBLEM TO BE SOLVED: To provide an auxiliary apparatus for connecting attachment equipment, which forcedly draws a lower arm inside, opens the lower arm outside or moves it so as to simply connect the attaching portion of the lower arm to the connection pin of the attachment equipment.SOLUTION: The auxiliary apparatus for connecting attachment equipment is equipped with an operation apparatus S1 for freely moving the lower arm in the transverse direction or in the horizontal direction and a mounting fixture 4 for fixing the operation apparatus S1 to the lower arm 90. The operation apparatus S1 is equipped with an operation body 1 to be griped by an operator and an rotatably arranged operating part 3. The operation apparatus S1 draws the lower arm inside, opens the lower arm outside and moves it by pulling up or down the operation body 1 in a state in which the operating part 3 is attached to the mounting fixture 4 so as to rotate the operating part 3.COPYRIGHT: (C)2008,JPO&INPIT【課題】ロワーアームを強制的に内側に寄せたり外側に開いたり動かすことができるようにして、ロワーアームの取付部とアタッチメント機器の連結ピンが簡単に連結できるアタッチメント機器連結補助装置を提供する。【解決手段】ロワーアームを横方向または水平方向に自在に動かすための操作装置S1と、操作装置S1とロワーアーム90を固定する装着具4を備えている。操作装置S1は、操作者が握り持つ操作体1と、回動可能に取り付けてある作動体3を備えている。操作装置S1は、作動体3を装着具4に取り付けた状態で、操作体1を引き上げたり押し下げたりして作動体3を回動させることにより ロワーアームを内側に寄せたり外側に開いたり動かすことができる。【選択図】 図1
