A vice is comprising a movable clamp member that can be positioned and fixed in a prescribed position corresponding to the size of a workpiece, before fixing the workpiece, wherein the mechanism for achieving this positioning and fixing operation can be simplified, and the stroke of a fluid pressure cylinder can be shortened. This vice (1) comprises: a guiding and fixing mechanism (13) capable of guiding a movable clamp member (4) movably in a prescribed direction with respect to a movable base member (10) in the main body of the vice (2), and also capable of fixing same in a releasable fashion; a first serration (53) formed in the movable base member (10), a second serration (54) formed in the movable clamp member (4) so as to be intermeshable with the first serration (53), a guide groove (55), an anchor member (56) disposed slidably in the guide groove (55), and a plurality of bolts (57) capable of fixing the movable clamp member (4) to the anchor member (56) in a state where the first and second serrations (53, 54) are intermeshed.
