An object is to improve the durability of wings and suppress vibration of the wings and generation of noise. A fluid machine includes a rotatably supported wing support, and a plurality of wings ( 21 ) formed on the wing support at a plurality of circumferential locations and protruding radially outward. The wings ( 21 ) each include a first wing element extending radially outward from a first attachment position on the wing support, a second wing element extending radially outward from a second attachment position on the wing support, and a third wing element connecting the first and second wing elements. In this case, the first and second wing elements are formed in such a manner to protrude radially outward from the wing support, and are mutually connected by means of the third wing element. This structure prevents damage to the wings ( 21 ), which damage would otherwise occur, for example, upon reception of external force, and thus improves the durability of the wings ( 21 ). Further, since stresses imposed on the third wing element can be reduced, deflection of the wing ( 21 ) caused by variation in loads imposed on the first and second wing elements can be reduced.
