PROBLEM TO BE SOLVED: To provide a clamp device that can surely clamp an object to be clamped, such as a work-piece.SOLUTION: The clamp device comprises a lock member (80) that can be inserted into a hole (11) of a work-piece (10), and a clamp rod (70) to be put in wedge engagement with the lock member (80) from above. The lock member (80) comprises a base part (85) to be inserted into the hole (11), and a protruding part (87) arranged above the base part (85). A relative movement restricting mechanism (M) that restricts a clamp rod (70) so as not to descend beyond a predetermined distance relative to the lock member (80) permits an outer peripheral face (85a) of the base part (85) to descend relatively to an inner peripheral face of the hole (11) at a diameter expanding position of the lock member (80).SELECTED DRAWING: Figure 5 |
