Disposed is a laundry treating apparatus having a rotator. The rotator includes a bottom portion positioned on a bottom surface of a drum, a pillar protruding from the bottom portion toward an open surface of the drum, wherein the pillar is formed in a hollow shape, a blade protruding from an outer circumferential surface of the pillar, wherein the blade extends from one end thereof facing toward the bottom surface to the other end thereof facing toward the open surface, and a cap coupled to an end of the pillar to close an interior of the pillar, and the blade is disposed such that the other end thereof is spaced apart from the cap. Accordingly, it is possible to minimize deformation of the pillar in manufacturing the rotator.
