<p>[PROBLEMS] To provide a clamp which can enhance machining precision of a work by suppressing generation of chatter vibration when the work is machined by means of a machine tool. [MEANS FOR SOLVING PROBLEMS] The clamp (8) is provided with abutting devices (9) for clamping a work (2) when it is machined by means of a machine tool. The abutting device (9) comprises a plurality of portions (14) abutting against the surface of the work (2), a press-urging means (16) for press-urging the plurality of abutting portions (14) toward the work (2), and a means (17) secured to the body of the clamp (8) and moving in the same direction as the press-urging direction of the press-urging means (16) when the plurality of abutting portions (14) abut against the work (2) to stop at the position kept abutting against the work (2) so as to prevent retraction of the abutting portions (14) by utilizing noncompressive fluid.</p> |
