A clamping device (10) has a clamp arm (20) pivotably housed inside a main body (16), and a locating section (54) for positioning workpieces (W1, W2) is provided at an upper portion of the main body (16). The locating section (54) is formed with a slit hole (60) which enables a claw portion (76) of the clamp arm (20) to protrude outside, and is provided inside with a shutter (66) facing the slit hole (60) and being movable. The claw portion (76) of the clamp arm (20) is inserted through a clamp hole (72) of the shutter (66). Then, when the clamp arm (20) moves inside the main body (16) in theaxial direction and rotates, the shutter (66) moves integrally with the clamp arm (20) along the axial direction to cover the slit hole (60). Thus, the opening portion of the slit hole (60) is suitably covered except the portion occupied by the claw portion (76), so that foreign matter and the like can be prevented from entering the locating section (54) through the slit hole (60). 一种夹持装置(10)具有可枢转地容纳在主体(16)内的夹持臂(20)，并且在主体
