PROBLEM TO BE SOLVED: To provide a multiple disks dehydrator, in which a torque required for the driving of a filter body in the multiple disks dehydrator is reduced, and a reduction in overload and in consumption power can be aimed at. SOLUTION: In place of the conventional dehydrating tanks for dehydrating a treating liquid, this dehydrating tank is provided with a filter body constituting a filter body row, which has a plurality of groups composed of a rotating shaft, a filter piece and a spacer. In the dehydrating tank, a plurality of the filter bodies are divided into a normal disc type filter piece and a small diameter filter piece which is a disc having a smaller outer diameter than the normal filter piece, a plurality of spacers are divided into a normal spacer in a rosette form and a large diameter spacer which is a disc having a larger outer diameter than the normal spacer, and a filtrate discharging gap through which the filtrate passes in a longitudinal direction of the rotating shaft is provided at the filter piece and the spacer, and the filtrate discharging gap provided at the large diameter spacer is a gap not connected with the outer edge.
