1. A turbomachinery comprising:
a casing;
a rotor shaft that is rotatably attached to the casing;
a first blade row that includes a plurality of first blades fixed to either one of the rotor shaft or the casing and attached at constant pitches in a circumferential direction of a central axis line; and
a second blade row that includes a plurality of second blades fixed to another of the rotor shaft or the casing, arranged adjacent to the first blade row on an upstream side or downstream side of the first blade row, and attached at constant pitches in the circumferential direction of the central axis line,
wherein
the turbomachinery sets the number of first blades and the number of second blades in a manner so that an interblade phase angle of the second blade row is ±180°.
