PROBLEM TO BE SOLVED: To provide a bearing device having sufficient durability and achieving sufficient lubrication performance, and to provide a rotary machine including the bearing device.SOLUTION: A bearing device 10 includes: a carrier ring 11 which is disposed so as to enclose a rotary shaft 20, which may rotate around an axis O extending in a horizontal direction, from the outer periphery side; a bearing pad 13 which is disposed between the rotary shaft 20 and the carrier ring 11 and in which a first pad surface P1 for slidably supporting the rotary shaft 20 through a lubrication oil is formed at the inner periphery side; and a side plate fixed to the carrier ring 11 from an axis O direction, configured to restrict movement of the bearing pad 13 in the axis O direction, and including a second pad surface P2 which slidably supports the rotary shaft 20 through the lubrication oil and is formed in the inner periphery side of the side plate.SELECTED DRAWING: Figure 2 【課題】十分な耐久性と潤滑性能を有する軸受装置、及びこれを備える回転機械を提供する。【解決手段】軸受装置１０は、水平方向に延びる軸線Ｏ回りに回転可能な回転軸２０を外周側から囲むように配置されるキャリアリング１１と、回転軸２０とキャリアリング１１との間に配置されて、内周側に潤滑油を介して回転軸２０を摺動可能に支持する第１パッド面Ｐ１が形成された軸受パッド１３と、キャリアリング１１に軸線Ｏ方向から固定されて、軸受パッド１３の軸線Ｏ方向の移動を規制するとともに、内周側に前記潤滑油を介して回転軸Ｏを摺動可能に支持する第２パッド面Ｐ２が形成されたサイドプレートと、を備える。【選択図】図２
