Abstract: A shaft precision automatic measurement device for motors is provided that is able to automatically measure shaft precision of a motor. A shaft precision automatic measurement device (1) for a motor (9) includes: a gripping mechanism (3) that grips the shaft (7); a first contact-type displacement sensor (41) that is able to measure a position of the flange face (82) by contacting to follow the flange face (82); a second contact-type displacement sensor (42) that is able to measure a position of the fitting face (81) by contacting to follow the fitting face (81); a rotary mechanism (5) that causes the device main body (2) to rotate in a state gripping the shaft (7) by the gripping mechanism (3) and executing measurement by way of the respective displacement sensors; a displacement data acquisition part (63) that acquires displacement data of the flange face (82) and displacement data of the fitting face (81); and a measurement part (64) that measures center runout and face deflection of the shaft (7) based on the respective displacement data acquired by the displacement data acquisition part (63).
