GREASE FEEDING PIPING ARRANGEMENT STRUCTURE IN CONSTRUCTION MACHINE
In a construction machine where an arm, a working attachment, and a distal end portion of an extensible cylinder are coupled via a power link and an idler link, to achieve protection of a grease feeding piping when the grease feeding piping is arranged in the idler link, and to ensure that the structure of the idler link is not complicated. In an idler link, there is formed a protruding part which protrudes in a direction opposite to a bucket from a link body part of the idler link; there is provided a grease feeding piping arrangement space which extends in a link length direction, toward right and left inside of right and left outer side faces of the protruding part, with at least either one side of the side opposite to the bucket or right and left inward sides open; and a grease feeding piping is arranged in the grease feeding piping arrangement space, in a state of not protruding in a direction opposite to the bucket beyond a protruding distal end portion face of the protruding part and not protruding toward right and left inside beyond right and left inner side link faces of the link body part.
