Zusammenfassung:	PROBLEM TO BE SOLVED: To detect the set state of a workpiece without using an air pipe and signal wiring. SOLUTION: A recessed part is provided on an inner diameter side of a rotation mechanism. A proximity sensor 22 provided with a transmission antenna 48 is arranged in the recessed part. The rotation mechanism is provided with a communication hole 90 opened in the recessed part, opened in an outer diameter surface of the rotation mechanism and having an electromagnetically shielded hole inner wall. An introducing hole 92 for introducing a detection signal of the proximity sensor 22 is provided, and a reception antenna 26a of a receiver 26 is arranged in the introducing hole 92 at a position opposed to a signal exit side opening of the communication hole 90 when rotation of the rotation mechanism is stopped on a fixed side opposed to an outer diameter side of the rotation mechanism.
