Abstract:
An axial flow rotating machine has: a rotor with a plurality of rotor blades; a stator with a plurality of stator blades; an axial flow rotating portion defined by the rotor and the stator; and a diffuser connected to the axial flow rotating portion on a downstream side of the axial flow rotating portion. A final blade portion inner-circumferential inner wall, which is a portion of an inner-circumferential inner wall of the axial flow rotating portion, is defined such that a diameter thereof at a trailing edge position of a final blade is smaller than the diameter at a leading edge position of the final blade. In addition, a diameter of all or a portion of a diffuser inner-circumferential inner wall decreases in a direction of the downstream side in an axial direction.

Claim (Index 12):
The axial flow rotating machine according to  claim 10 , wherein the inclination angle of the first inclination portion or the inclination angle of the second inclination portion is equal to or greater than an average inclination angle from a leading edge to a trailing edge of the final blade on the final blade portion inner-circumferential inner wall and is less than 0 degrees.
