Abstract
A main controller of a work machine computes target position information of an entry-prohibited area plane on the basis of operation information of a console switchor a monitor operation device, decides, on the basis of the target position information of the entry-prohibited area plane, whether or not a distance rbetween a target position M of the entry-prohibited area plane and the center O of swing action of an upper swing structure is greater than a threshold value set based on a distance rfrom the center O of swing action of the upper swing structure to a rear end of the upper swing structure, validates the target position information of the entry-prohibited area plane when the distance ris greater than the threshold value, and sets the entry-prohibited area plane at the target position M.
