業アタツチメントの軸受構造。 A push link member and a rod boss member are connected to the inner sides of a pair of left and right idler link members via a pin, and the push link member and the rod boss member are rotatably connected to the pin at a pin joint portion. A bushing member that is slidable in the pin axis direction is inserted into the pin hole of the member, and a load sealing member is provided between the opposing end faces of the rod boss member, push link member, and idler link member, respectively. The inner periphery of the load seal member is brought into contact with the entire outer periphery of the pin, and a tightening fitting is provided at one end of both ends of the pin, and the metal fittings penetrate through the three members of the idler link member, push link member, and rod boss member. When the pin is inserted into the pin insertion hole and the fastening fitting is further tightened and fixed to the end face side of the pin, the load sealing member is configured so that it can be compressed and fitted between the end face portions of each of the three members. The bearing structure of the working attachment.
