PROBLEM TO BE SOLVED: To simplify the internal structure of a pump by a reasonable means. SOLUTION: This shaftless pump comprises a rotating vane rotated by the drive force of a driving source and a tubular support member rotatably supporting the rotating vane through a bearing means. The rotating vane is rotated by the drive force of the driving source installed on the outside of the rotating vane, and formed of a cylindrical body having a hollow part guiding a fluid in one direction from its one end face to the other and a wide vane body having a spiral outer peripheral end fixed airtight to the inner peripheral surface of the cylindrical body.
