置。 In a device for measuring the relative distance between a skin plate 3 and a segment 2 of a shield excavator, the shield excavator is arranged in a straight line in the radial direction of the shield excavator on a surface opposite to the surface of the spread dash 1 of the shield excavator that is crimped to the segment. , a first ultrasonic probe 4 consisting of a plurality of transducers that emits ultrasonic waves to the segment, and a second ultrasonic probe 5 that emits ultrasonic waves to the skin plate 3 disposed on the spread dash. , a first distance detecting section 6 that detects the relative position of the segment with respect to the spretz dash based on the signal received by the first ultrasonic probe, and a second distance detecting section 6 that detects the distance between the sprate dash and the skin plate based on the signal received by the second ultrasonic probe. A gap measuring device comprising a detection section 7 and a distance addition section 8 that obtains the distance between the segment and the skin plate from the output of the first detection section and the output of the second detection section.
