The present invention is a pulp screening device which is capable of screening a large quantity of pulp with low power, by preventing clogging of a screen cylinder. The device is provided with one or a plurality of vanes (12, 21) which revolve within an agitation chamber (7) formed between a pair of inner and outer screen cylinders (1a, 1b), holding a predetermined small space from each of the inner and outer screen cylinders (1a, 1b). The agitation chamber (7) is practically partitioned in the circumferential direction by the vanes (12, 21). <IMAGE>
