PROBLEM TO BE SOLVED: To provide an abnormality diagnostic device to surely recognize the message of abnormality generation of the equipment to an operator even under any working condition. SOLUTION: When a failure (an abnormality) of each equipment such as angle sensors 6a-6c and solenoid valves 11a-1 to 11c-2 is judged by an abnormality detection part 7e, and when a failure occurs, the control signal is outputted from the abnormality detection part 7e to a display part 12, a lamp 13 and an odor generation part 14. As a result, a failure message is displayed on the display part 12, the lamp 13 is flickered, the odor generation part 14 is operated, and a specified odor is sprayed into the air from an odor spray part 15. Since an operator is stimulated to pay his attention by smelling this odor, he can surely recognize generation of failure by watching the failure message displayed on the display part 12.
