PURPOSE:To simplify assembly of vanes by furnishing a ring-shaped groove in a partition plate of this through flow impeller in its part where the free end-faces of the train of vanes are welded. CONSTITUTION:A ring-shaped groove 2a concentrical with the axis of a partition plate 2 is formed at the A-side of this partition plate 2, and one end 1a of each fixed vane 1 is fitted at the B-side. According to this arrangement only location in the radial direction is required even though vanes 1 between partition plates to constitute the through flow impeller are not arranged at a constant spacing and have similar forms, which should well enhance the effectiveness in works.
