The compressed air from the air pressure source 12 is supplied through the nozzles 0, and the compressed air is blown from each nozzle 7 to the outer peripheral surface of the work W. Thereby, a back pressure corresponding to the distance between the discharge port of the nozzle 6 and the outer peripheral surface of the work W is generated on the upstream side of each nozzle 6.

Thereby, a back pressure corresponding to the distance between the discharge port of the nozzle 9 and the inner peripheral surface of the work W is generated on the upstream side of each nozzle 9. Therefore, on the upstream side of the branch pipe joint 11, the branch pipe joint 1
The back pressure corresponding to the average value of the distance between each nozzle 9, 9 of the pair of inner diameter measuring heads 8, 8 corresponding to 1 and the inner peripheral surface of the work W is generated.
