Zusammenfassung:	To provide a water turbine generator which enables simplification of a mechanism.SOLUTION: A water turbine generator has: a runner 31; and a swirl flow generating function part 22 provided at the upstream of water flow relative to the runner 31. In the runner 31, a center shaft 32 is supported by bearings 60, 60 fixed to body parts 21, 41. The bearings 60 are made of a non-metal and disposed in a path of the wafer flow. The runner 31 includes a rotor 35 having a magnet 35a or a coil at its outer periphery part. An outer periphery part of the rotor 35 has a stator 50 having a coil. The bearings 60 are rolling bearings and their raceway are made of a non-metal.SELECTED DRAWING: Figure 1 【課題】本発明によれば機構を簡素化できる水車発電機を提供する。【解決手段】ランナ３１と、ランナ３１より水流の上流に設けた旋回流発生機能部２２とを有し、ランナ３１は、中心軸３２が本体部２１、４１に固定された軸受６０、６０で支持される。軸受６０は非金属からなり、水流の経路中に配置される。ランナ３１は外周部に磁石３５ａまたはコイルを有するロータ３５を備える。ロータ３５の外周部にコイルを有するステータ５０を有する。軸受６０は、転がり軸受であり、軌道が非金属である。【選択図】図１
