Zusammenfassung:PROBLEM TO BE SOLVED: To provide a water flow power generation device miniaturized and improved in efficiency.SOLUTION: A water flow power generation device 1 includes a blade 23 rotated by the force of water flow, a rotating part 21 connected with the blade 23 and rotating integrally with the blade 23, a power generation unit 6 connected with the rotating part 21 and generating power with rotational force of the rotating part 21, an internal space V which covers the power generation unit 6 and in which the power generation unit 6 is disposed, a nacelle 7 forming a boundary with water in which the blade 23 is arranged and allowing the atmosphere in the internal space V to become the gaseous atmosphere, and a bearing unit 4 supporting the rotating part 21 with respect to the nacelle 7. The bearing unit 4 includes a thrust bearing 41 provided in the internal space V and supporting the rotating part 21 from an axial direction, and a journal bearing 42 provided between the nacelle 7 and the blade 23 and supporting the rotating part 21 from a radial direction.SELECTED DRAWING: Figure 2 【課題】小型化され、かつ効率の向上した水流発電装置を提供する。【解決手段】水流発電装置1は、水流の力で回転するブレード23と、ブレード23に連結され、ブレード23と一体で回転する回転部21と、回転部21に連結され、回転部21の回転力で発電する発電ユニット6と、発電ユニット6を覆い、発電ユニット6が配置された内部空間Vと、ブレード23が配置された水中との境界を形成し、内部空間Vを気体雰囲気とするナセル7と、ナセル7に対して回転部21を支持する軸受ユニット4と、を備える。軸受ユニット4は、内部空間Vに設けられ、回転部21を軸方向から支持するスラスト軸受41と、ナセル7とブレード23との間に設けられ、回転部21を径方向から支持するジャーナル軸受42と、を有する。【選択図】図2
