Abstract
In a clamping device, a detection mechanism detects a state of clamping/unclamping and includes: a detected body that moves together with a piston and a piston rod; a circuit board disposed to face the detected body and capable of detecting the position of the detected body; and an indicator lamp that is connected to the circuit board and is lit/extinguished depending on the state of clamping/unclamping. By pressing a setting button provided on the detection mechanism when the rotation angle of the arm is changed, the second detection position of the circuit board for detecting the unclamped state is changed, making it possible to detect the detected body at a newly set detection position.
