In the clamping device (10), a detection mechanism (24) that detects the state of clamping/unclamping is provided with; a detected body (96) that moves together with a piston (48) and a piston rod (50); a circuit board (94) disposed so as to face the detected body (96) and capable of detecting the position of the detected body (96),; and an indicator lamp (108) that us connected to the circuit board (94) and is lit/extinguished depending on the state of clamping/unclamping. By pressing a setting button (110) provided on the detection mechanism (24) when the rotation angle of the arm (22) is changed, the second detection position (128) of the circuit board (94) for detecting the unclamped state is changed, making it possible to detect the detected body (96) at a newly set detection position. |
