A transfer conveyer without shaft is provided, in which the contact of liner and screw without shaft is minimized and the abrasion of liner can be prevented and screw can be steadily rotated. A transfer conveyer without shaft comprises: a casing(10) in which an inlet is formed in one side and an outlet is formed in the other side; a screw without shaft that is inserted into the casing in the length and is rotated; and a driving part including a motor rotating screw without shaft. An upper plate(41) and a lower plate(42) are combined and form a liner(40). A roller(43) is inserted into a groove(41a) of the upper plate and partly protruded to the outer side. In the edge groove(42a) of the lower plate, a ball is formed and supports both sides of the roller.
