Zusammenfassung:	A coupler having elastically deformable claws 32, 33 is fixed to the side plate 103 of one segment 1a. The side plate 103 of the one segment 1a and the side plate 102 of the other segment 1b are butted against each other, and the claws of the coupler are passed through the side plate of the other segment to protrude into the segment. The claws of the coupler protruding into the other segment are elastically deformed by a diameter expansion pin 11 to expand the diameter of the claws 32 and 33. The claws of the coupler whose diameter has been expanded presses the side plate of the other segment against the side plate of the one segment to couple both the segments in the longitudinal direction.
