Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a working machine allowing even a worker to easily perform grease feeding work to a turning bearing and to perform the safe grease feeding work.SOLUTION: This working machine includes: a lower traveling body; an upper turning body turnably provided on the lower traveling body and provided with a cab 7; a turning device for turnably supporting the upper turning body on the lower traveling body; and a grease feeding port provided in an outer ring of the turning bearing constituting the turning device to supply lubricating oil to the turning bearing. In the cab 7 of the upper turning body, filling ports 18 and 19 for filling the lubricating oil in the grease feeding port are installed, and the filling ports 18 and 19 and the grease feeding port are connected by a pipe. Further, the working machine includes a malfunction prevention means (grease feeding switch 26, etc.) for preventing various kinds of actuators from erroneously operating during the grease feeding work to the filling ports 18 and 19.
