    • PROBLEM TO BE SOLVED: To provide an ocean current power generating apparatus that aims to lengthen life and improve reliability.SOLUTION: An ocean current power generating apparatus comprises: a rotating shaft for transmitting a rotary driving force of rotary blades; guide bearings each having a second sliding surface that slides against a first sliding surface as a side surface of the rotating shaft and each of which supports a radial load acting in a radial direction of the rotating shaft; thrust collars attached to the rotating shaft and each having a rotating plate; and thrust bearings each having a fourth sliding surface that slides against a third sliding surface as a main surface of the rotating plate and each supports a thrust load acting in the axial direction of the rotating shaft. The first and third sliding surfaces are formed of iron material, stainless material, titanium, titanium alloy, cobalt or cobalt alloy, and the second and fourth sliding surfaces are formed of resin material in which a first fibrous member and a second fibrous member having smaller dimension than the first fibrous member are injected.
