PURPOSE: A device for installing and removing an attachment of working apparatus is provided to accomplish a simple structure, a low cost, a high durability, an automatic combination of hanging and an easy adjustment of inserted center of pin without regard to a size of attachment. CONSTITUTION: A second member(2) is suspended downward with both concave portions(8,8) of downward opening. An automatic combination of hanging is smoothly performed by inducing a fourth horizontal pin(P4) located under concave portions(8,8) into concave portions(8,8) by extending a hydraulic cylinder(4). Both concave portions(8,8) have a front and a rear inclined faces. The fourth horizontal pin is slid up the rear inclined face when a distance between a third and the fourth horizontal pins(P3,P4) are short and the fourth horizontal pin is slid up the front inclined face when the distance is long. Therefore, a change is performed in an attachment of working apparatus having a different distance between the third and the fourth pins(P3,P4). |
