Abstract
An object of the present invention is to provide a work machine that is capable of flexibly setting an entry-prohibited area for a work device according to an operator's intention. To achieve this, a controllersets, as a first position, the position of a work toolthat is located when a setting switchis operated, and sets, as a second position, the position of the work toolthat is located when the setting switchis operated after the setting of the first position. Further, the controllersets, as a boundary surface of an entry-prohibited area, a planethat passes through a first reference point A and a second reference point B and that is perpendicular to a ground contact surface of a lower track structure. The first reference point A is one of a plurality of reference pointsL andR on the work toollocated at the first position, the plurality of reference pointsL andR being preset on the work tool. The second reference point B is one of the plurality of reference pointsL andR on the work toollocated at the second position.
