PROBLEM TO BE SOLVED: To provide a door opening-closing abnormality monitoring device of an elevator for putting the elevator in a respective floor door opening-closing diagnostic operation mode by returning from earthquake emergency mode, when there is no abnormality, by automatically performing door opening-closing torque/door opening-closing time inspection operation of the reference floor (normally, the first floor), in the elevator stopping by earthquake emergency operation after an earthquake occurs. SOLUTION: This door opening-closing abnormality monitoring device of the elevator stopping by the earthquake emergency operation after the earthquake occurs, prestores ordinary door opening-closing torque or door opening-closing time, and performs the door opening-closing inspection operation for comparing the door opening-closing torque or the door opening-closing time after the earthquake occurs with those of normal time, and puts the elevator in the respective floor door opening-closing diagnostic operation mode by returning from the earthquake emergency mode when there is no abnormality in a door opening-closing diagnosis in the reference floor.
