ABSTRACT:
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.
