Abstract
A tilting pad gas bearing includes: a plurality of bearing pads disposed in a circumferential direction of a rotor; and a pivot member that swingably supports the bearing pads. Each of the bearing pads has a curved shape and includes: a pad main body supported by the pivot member; a heat insulating material layer disposed on a side of the pad main body that faces the outer circumferential surface of the rotor, and formed of a material having a thermal conductivity lower than a thermal conductivity of the pad main body; and a concave portion disposed in an outer circumferential surface on an outer circumferential side of the bearing pad in a curving direction. A base end of the pivot member is fixed to a housing, and the pivot member has a protruding portion that passes through the housing.
