PROBLEM TO BE SOLVED: To provide a working machine capable of rotating an underground pile by a driving device to bury it into the ground, increased in safety of work, and improved in work efficiency. SOLUTION: An upper part base 3 is turnably attached to an upper part of a lower part running body 2. The driving device 5 is attached to the upper part base 3 through a leader. A cylindrical member in which an upper side of the underground pile T is inserted is provided in the driving device 5. A chuck mechanism for holding the underground pile T inserted into the cylindrical member is provided in the driving device 5. An attitude switching mechanism for switching attitude of the driving device 5 is provided between the driving device 5 and the leader 6. Attitude of the driving device 5 is switched to attitude for burying the underground pile T and attitude for inserting and holding the underground pile T into the cylindrical member by the attitude switching mechanism.
