Stator blade row of the turbo-type fluid machine

In the present invention, each interval between the vane SV with adjacent sequences such that the unequal at least in part. With this arrangement the stator blades, the wavefront having different traveling directions and phase formation, since these decays to each other interfere with each other, the interference noise can be reduced. Accordingly, the present invention, it is possible to reduce the amount of sound absorbing material, may reduce the interference noise without enlarging the dynamic and stationary blades intervals.
