PROBLEM TO BE SOLVED: To deliver a fluid of high pressure by a small blower by arranging a plural stages by combining a moving blade with a stationary blade in a radial direction of a clearance, in a device formed in such a constitution that a fluid of an axial direction flow is delivered through the moving blade and the stationary blade which are bent in the radial direction in the clearance between an impeller and a diffuser. SOLUTION: A casing of a centrifugal type mulitiblade blower F consists of a spiral casing main body 1 provided with a delivery port 10 on an upper part extending from an intake port 9 of an axial direction to a radial direction, and a back plate 2, and a hollow disk diffuser 3 for bending flow in the radial direction is arranged on a driving machine side of the casing main body 1. An impeller 4 rotated by a driving machine M is arranged inside the back plate 2 opposed to the diffuser 3. A stationary blade 3a is arranged on the diffuser 3 opposing to the impeller 4, a moving blade 4a is arranged on the impeller 4, and a plural stages are arranged in the radial direction by combining the moving blade 4a with the stationary blade 3a. A seal member 7 is interposed between the back plate 2 and the impeller 4 so as to seal a delivery fluid.
