PROBLEM TO BE SOLVED: To suppress deformation or change of a relative position of a stationary body and a rotor with displacement of a diaphragm, and then prevent contact of the stationary body and rotor.SOLUTION: A centrifugal rotary machine includes: a rotor 2 that has a rotational shaft 4 rotating around an axial line P and an impeller 3 rotating together with the rotational shaft 4; a casing 7 that surrounds the rotor 2 from an outer peripheral side; a plurality of diaphragms 6 that is provided in an axial line P direction between the rotor 2 and the casing 7, and defines a flow passage of a fluid G pressure-fed by the impeller 3; and a constraint member 20 that constrains the diaphragms 6 from the outer peripheral side.SELECTED DRAWING: Figure 1 【課題】ダイヤフラムの変位に伴う静止体と回転体の相対位置の変形や変化を抑制し、静止体と回転体との接触を防止する。【解決手段】軸線Ｐ回りに回転する回転軸４及び回転軸４とともに回転するインペラ３を有するロータ２と、ロータ２を外周側から囲むケーシング７と、ロータ２とケーシング７との間に軸線Ｐ方向に複数が積層されるように設けられて、インペラ３によって圧送する流体Ｇの流路を画成するダイヤフラム６と、ダイヤフラム６を外周側から拘束する拘束部材２０と、を備える遠心回転機械。【選択図】図１
