PROBLEM TO BE SOLVED: To provide a solid-liquid separator which has a plurality of fixed plates, a movable plate arranged between adjacent fixed plates, and a deliquoring screw passing through the fixed plate and the movable plate and extending, flows down a water content of the sludge from a gap between the fixed plate and the movable plate while sludge is carried with a rotation of the deliquoring screw, and which prevent wear of the movable plate and reduce the running cost of the solid-liquid separator. SOLUTION: A pressurized member 39 is detachably attached to the movable plate 12, a driving screw 41 passes through the pressurized member 39, and the movable plate 12 is reciprocatory by the pressurization of the pressurized member 39 with the rotation of the driving screw 41.
