Abstract
Provided is a work machine including a controller configured to perform area restriction control for preventing a vehicle body from deviating from a work area set in a construction area. In this work machine, it is possible to easily set an area for which operation of the work machine is to be restricted in an actual space to a desired position, and to avoid displacement of the area for which the work machine is to be actually controlled from the set area. The work machine includes a controller configured to perform area restriction control for restricting operation of a vehicle body so as to prevent the vehicle body from deviating from a work area set in a construction area. The controller sets at least a part of the work area based on design data representing a final intended shape of a construction target in the construction area.
