  "textContent": "A construction machine includes a posture sensor that is provided on a front member of a front work implement and detects posture information of the front member, an external environment recognition device that detects an object around a main body, and a controller calculates a dead angle range that is a range that becomes a dead angle from a recognition range of the external environment recognition device, the dead angle arising from an object recognized by the external environment recognition device, calculates an assumed movement range that is a range within which a moving body assumed to exist in the dead angle is movable in a period of time determined in advance, calculates a movable range that is a range within which the front work implement is movable in a period of time determined in advance on the basis of the posture information detected by the posture sensor, and performs preventive control for preventing contact between the moving body and the front work implement on the basis of the assumed movement range of the moving body and the movable range of the front work implement. Consequently, the construction machine can deal also with a moving body in a dead angle of an object sufficiently and can prevent contact between the front work implement and a moving body with a higher degree of certainty.",
