PROBLEM TO BE SOLVED: To provide a clamp for an oscillation arm to have high stability and strength and be excellent in a reliable clamp operation point. SOLUTION: In a screw clamp 2 provided with an oscillation arm which has a rotatable transmission device part having a rotary grip 12 being worked on one clamp jaw 3 in such a manner that it is relatively rotatable but not moved, a non-rotatable transmission device part is worked on the other clamp jaw 4 in such a manner that it is non-movable, and the two jaw clamps 3 and 4 being not relatively rotated but movably guided, the rotatable transmission device part is constituted in such a manner that a nut 7 is formed and a rotary grip 12 is provided, and a stand 1 is relatively rotatably extended through the hole 20 in an axial direction of the rotary grip 12 and supported at the jaw 3. |
