To prevent the wear of a screw part and hold a work stably by cutting a screw part meshed with the screw part cut on a feed shaft to the arc shape periphery edge formed on the ceiling position of a through hole penetrated by the feed shaft and the bottom position of the through hole.

When the holding of a work W by a fixed vice and a movable vice is finished, a feed shaft 40 is pushed down vertically. Then, a swing block 31 pivoted to a swing pin 32 and rotated is returned to the position before rotating and the upper screw part 31b and lower screw part 31c of the swing block 31 are meshed with the screw part 40a of the feed shaft 40. When a handle H installed on the end of the feed shaft 40 through a shaft S after meshing is rotated in a tightening direction, the movable vice is fed and the holding and fixing of the work to the vice device is finished.
