PURPOSE: A power increasing device for a vise is provided to improve the quality of products, and to reduce reject rate by firmly keeping the position of a workpiece. CONSTITUTION: A coupling hole(11) is formed at the center of a body unit(10). Through holes(12) are formed at both sides of the front of the body unit. A first guide groove(16) is formed at regular intervals away from the center of the body. A first guide plate(20) is slid in the first guide groove. A first roller(21) is rotatably coupled with a mounting hole(23) formed at the upper part of the first guide plate. A guide groove(24) is formed at the lower part of the first guide plate, and guides a second roller(22). A second guide plate is slid in the first guide groove. A guide groove(24) is formed at the upper part of the second guide plate, and is coupled with the first roller. A compressing unit(40) is coupled with the coupling hole. The first guide plate and second guide plate are slidably fit into a second guide groove(51) formed at the front of a supporting unit(50). A coupling unit(60) is coupled with the through hole, and is fixed on a coupling groove(52) in the supporting unit.
