Abstract: When an operation amount of an operation lever corresponding to a boom cylinder is equal to or smaller than an operation amount of an operation lever corresponding to an arm cylinder, an estimated velocity of the arm cylinder used for region limiting control is computed on the basis of a first condition defining, in advance, a relation between the operation amount of the operation lever and the estimated velocity of the arm cylinder. When the operation amount of the operation lever corresponding to the boom cylinder is larger than the operation amount of the operation lever corresponding to the arm cylinder, the estimated velocity of the arm cylinder used for the region limiting control is computed as a velocity higher than the estimated velocity of the arm cylinder computed on the basis of the first condition. The behavior of the work device can thereby be stabilized.
