<P>PROBLEM TO BE SOLVED: To provide a guide vane of a fluid machine which optimizes a flow direction of pressure water in an outlet of a guide vane and can control cavitation generated at a suction surface side of a runner vane, and the fluid machine thereof. <P>SOLUTION: Between an upper cover 20 and a lower cover 21, the guide vane 18 is provided rotatably around a central axis O parallel to a rotating shaft of a runner 12, and adjusts a flow rate to guide a working fluid to the runner 12 side. A cross-sectional shape of the guide vane 18 which is perpendicular to the central axis O is different in the lower cover 21 side and at the center in a height direction of the guide vane 18. <P>COPYRIGHT: (C)2012,JPO&INPIT |
