A clamp device (10) is equipped with a clamp body (14), a piston rod (30), a link mechanism (16), a detection mechanism (18) for detecting a state of rotary motion of a clamp arm (17), and a determination unit (124) for determining whether a state of clamping exists. The detection mechanism (18) includes a first proximity sensor (102a), and a knuckle joint (61) having a first sloped surface (98). The determination unit (124), on the basis of a comparison of an output signal from the first proximity sensor (102a) to a clamp threshold value (Z1), determines whether a state of clamping exists, and on the basis of a comparison to a clamping force generation threshold value (Z3), determines whether a state of generation of clamping force exists. |
