Zusammenfassung:PROBLEM TO BE SOLVED: To provide a bearing device of a water-including part excelling in wear resistance, and capable of preventing seizure of a rotating shaft. SOLUTION: A large-diameter bearing hole 11 is formed at a bearing arrangement position of an outer tube 10 for inserting a rotating shaft 20 connecting a power source to a rotating vane; an annular space between the bearing hole 11 and the rotating shaft is divided into n circular spaces 1 by n virtual radiation planes at equal angular intervals; and n segments 2 are composed by fixing, through rubber plates 4 as needed, wear-resistant bearing plates 5 to the undersurfaces of surface plates of semicylindrical fiber bodies 3 each having a bottom plate in contact with a large circular arc comprising the bearing hole 11 of each circular space 1. A flat undersurface middle point of the bearing plate 5 of each segment 2 contacts a tangential line in the periphery of the rotating shaft, and a space 6 capable of passing water is formed among both the undersurfaces of the two bearing plates 5, 5 adjacent to each other and the periphery of the rotating shaft. Each segment 2 is allowed to be independently extracted from the bearing hole 11 in a bus line direction, and is allowed to be mounted by pressing it in the bearing hole bus line direction.
