PROBLEM TO BE SOLVED: To protect a hydraulic hose connected to an attachment cylinder of a hydraulic attachment. SOLUTION: In this working device for a construction machine, a third connecting pin 29 for connecting the tip side of a second link 27 constituting a link mechanism 24, to a working tool attaching/detaching device 16 is rotatably provided with a hydraulic line fixing member 38 for fixing an intermediate part of the hydraulic hose 35. Consequently, when the working tool attaching/detaching device 16 turns on the tip side of an arm 14, the hydraulic hose 35 can be restrained from bending in large degree to rub against the working tool attaching/detaching device 16 or the like, so that the hydraulic hose 35 can be protected.
