A bearing device of embodiment is usable for a hydraulic machine having a rotary shaft of a vertical shaft, with a water tank storing lubrication water, and a bearing pad supporting a skirt member on the rotary shaft in the lubrication water. The bearing device has a first supporting mechanism slidably supporting the bearing pad from the radial direction, and a second supporting mechanism slidably supporting the bearing pad from a bottom portion side in an axial direction. One of a supporting surface supporting the bearing pad in the first supporting mechanism and a supported surface supported by the supporting surface in the bearing pad is formed in a convex shape. One of a supporting surface supporting the bearing pad in the second supporting mechanism and a supported surface supported by the supporting surface in the bearing pad is formed in a convex shape.
