    • PROBLEM TO BE SOLVED: To provide a power generation device capable of suppressing generation of smearing on a rolling bearing supporting an output shaft 35 of a speed-increasing gear.SOLUTION: A power generation device includes: a speed-increasing gear having a rolling bearing rotatably supporting an output shaft 35; a power generator having a driving shaft 41 rotated by inputting the rotation of the output shaft 35; and a one-way clutch 7. The one-way clutch 7 has clutch members 23, 24 disposed in opposition to each other in an axial direction between the output shaft 35 and the driving shaft 41; and conical rollers 25 disposed between the clutch members 23, 24. When a rotating speed of the output shaft 35 is higher than a rotating speed of the driving shaft 41, the conical rollers 25 are engaged with the clutch portions 23, 24 to integrally rotatably connect the output shaft 35 and the driving shaft 41. When the rotating speed of the output shaft 35 is lower than the rotating speed of the driving shaft 41, the engagement of the conical rollers 25 is released, and the output shaft 35 and the driving shaft 41 are disconnected from each other.
    • 要解决的问题:提供一种发电装置,其能够抑制在支承增速齿轮的输出轴35的滚动轴承上产生拖尾。发电装置包括:增速齿轮,具有滚动轴承 可旋转地支撑输出轴35; 发电机,其具有通过输入输出轴35的旋转而旋转的驱动轴41; 单向离合器7具有在输出轴35与驱动轴41之间沿轴向相互配置的离合器构件23,24; 以及设置在离合器构件23,24之间的圆锥滚子25.当输出轴35的转速高于驱动轴41的转速时,圆锥滚子25与离合器部分23,24接合成可一体旋转 连接输出轴35和驱动轴41.当输出轴35的转速低于驱动轴41的转速时,锥形辊25的接合被解除,输出轴35和驱动轴 轴41彼此断开。
