Bearing device and rotary machine
A bearing device includes: a carrier ring; a first bearing portion disposed along an outer periphery of a rotor shaft on a radially inner side of the carrier ring; a second bearing portion disposed along the outer periphery of the rotor shaft and downstream of the first bearing portion, with respect to a rotational direction of the rotor shaft, on the radially inner side of the carrier ring; and a pair of side plates disposed along the outer periphery of the rotor shaft, on both sides of the carrier ring with respect to an axial direction. In a carrier-ring side region of an inner peripheral surface of each of the side plates, a groove extending in a circumferential direction along a side surface of the first bearing portion is formed at least in a part of an extending range of the first bearing portion.
