摘要： Object
Both a structure that enables supply of a fluid to the pad and a structure that biases the pad toward a rotor shaft are achieved with a simple structure.
Solving Means
A tilting pad bearing includes a plurality of pads slidably supporting an outside surface of a rotor shaft, a housing covering the plurality of pads, a support portion swingably supporting the pad with respect to the housing, and a fluid supply unit configured to supply a fluid to a pad surface.
The support portion includes a pivot having a pad support surface in contact with a pad outside surface and a pivot curved surface curved facing and protruding toward a side opposite to the pad support surface, a liner having a first liner surface in contact with the pivot curved surface, and a biasing member biasing the liner toward the pivot with respect to the housing.
