Zusammenfassung:	A hydraulic excavator is provided which makes it possible to allow an operator to surely recognize an alarm that notifies the operator of non-wearing of a seatbelt even when a work is performed in a situation in which a moving object is present around the machine. A controller outputs, when a moving object is detected and wearing of a seatbelt is detected by a seatbelt detection device, a first alarm through a notification device, outputs, when the moving object is not detected and non-wearing of the seatbelt is detected by the seatbelt detection device, a second alarm through the notification device, and outputs, when the moving object is detected and non-wearing of the seatbelt is detected by the seatbelt detection device, the second alarm preferentially over the first alarm through the notification device.
