A bearing device of a gas turbine power generation equipment provides damping vibration of a shaft and lubricates and cools the bearing main body. The bearing devices have sleeves provided on the outer circumference sides of the bearing main bodies and bearing housings holding the respective sleeves via O-rings while each forming an annular clearance passage between each of the outer circumferences of the sleeves and a corresponding one of the bearing housings. The bearing housing has a feed-water hole communicating with the clearance passage and adapted to feed water thereto. The sleeve has a lead water hole communicating with the clearance passage and is adapted to lead water to the bearing main body, and a discharge hole which communicates with the clearance passage and is adapted to discharge water therefrom.
