摘要： The present invention provides a work fixing device capable of stably fixing the work, without any biasing, in the longitudinal direction of the work, of the fastening force for fixing the work. The moving mechanism 3 of clamps 2 is constructed by comprising a scroll disc 4 as working disc forming a circular hole 41 in which to insert the work W at the center and scroll guides 42a, 42b in spiral shape the winding direction of which is opposite to each other from the center toward the outer circumference on the both side faces, a rotary drive mechanism 5 for rotatably driving this scroll disc 4, and scroll pieces 6 having a fitting portion 61 to be engaged with the scroll guides 42a, 42b of the scroll disc 4 and disposed on both sides of the scroll disc 4 in a way to correspond to a plurality of clamps 2 respectively.
