Zusammenfassung:	To provide a fluid machine capable of inhibiting disc friction loss.SOLUTION: A fluid machine according to an embodiment is a fluid machine in which a runner is rotatably housed between an upper cover and a lower cover facing each other. The fluid machine includes: a back pressure chamber formed between the upper cover and the runner; a side pressure chamber formed between the lower cover and the runner; and a straightener which comprises blades provided in at least one of the back pressure chamber and the side pressure chamber and in each of which a blade surface inclines in a rotation direction of the runner from an upstream side end to a downstream side end of water stream flowing into the blade.SELECTED DRAWING: Figure 1 【課題】円板摩擦損失を抑制することができる流体機械を提供することである。【解決手段】実施形態の流体機械は、互いに対向する上カバーおよび下カバーの間にランナが回転可能に収容される流体機械であって、前記上カバーと前記ランナとの間に形成される背圧室と、前記下カバーと前記ランナとの間に形成される側圧室と、前記背圧室および前記側圧室の少なくとも一方に設けられる翼であり、この翼に流入する水流の上流側端部から下流側端部に向かって、翼面が前記ランナの回転方向に傾斜する整流装置と、を備える。【選択図】図１
