PROBLEM TO BE SOLVED: To provide a working machine connecting device enhanced in followability to the soil of a working machine.SOLUTION: In a working machine connecting device which connects a working machine for applying work to soil to a vehicle body, a link mechanism 34 connects the vehicle body and the working machine, and is extended/contracted between the vehicle body and the working machine. An extending and contracting mechanism extends and contacts the link mechanism 34. The link mechanism 34 presses the working machine to the soil and lifts the working machine by the extension and contraction of the extending and contracting mechanism. A spring member 42 of the extending and contracting mechanism absorbs loads transmitted to the link mechanism 34 from the vehicle body and the working machine, and converts the loads into the extension and contraction motion.COPYRIGHT: (C)2015,JPO&INPIT【課題】作業機の土壌への追従性を高めた作業機連結装置を提供する。【解決手段】土壌に作業をする作業機を車体に連結する作業機連結装置において、リンク機構34は、車体と作業機を連結し、車体と作業機の間で伸縮可能である。伸縮機構は、リンク機構34を伸縮させるためのものである。リンク機構34は、伸縮機構の伸縮によって、作業機を土壌へ押しつけ、または作業機を持ち上げる。伸縮機構のバネ部材42は、車体および作業機からリンク機構34に伝達される荷重を吸収して伸縮動作に変換する。【選択図】図3
