A bearing device includes a base plate, a plurality of sliding pads and support members. The sliding pad is movable relative to the base plate. The support members are located between the base plate and the sliding pad, and shift a position of a load supporting point in a circumferential direction of the base plate, the load supporting point serving as a point for supporting a load received from the sliding pad. When any virtual flat surface perpendicular to a rotating shaft member is considered as a reference surface, and when a distance from the reference surface through the load supporting point to an end of the sliding pad at the opposite side to the base plate is defined as a setting distance, a position of the load supporting point is shifted in a circumferential direction of the base plate with no change in the setting distance.
