PROBLEM TO BE SOLVED: To provide a bearing device having a sufficient damping effect. ! SOLUTION: A bearing device disposed to be spaced apart from a stator extending in a direction of an axis and supporting a rotor to be rotatable about the axis with respect to the stator, comprises: a damper ring provided between the rotor and the stator and disposed via a fluid-filled clearance from the stator; and a bearing body provided between the damper ring and the rotor and supporting the rotor to be rotatable about the axis with respect to the damper ring, the clearance including a portion in which the damper ring faces the stator in a radial direction, and a portion in which the damper ring faces the stator in the direction of the axis, and these portions being connected into a curved shape in a cross-section including the axis. !
