Claims9
A thrust bearing comprising:
- an upper foil portion including a bearing surface that faces a rotary member rotatable about a rotation axis;
- and
- a lower foil portion that elastically supports the upper foil portion, wherein the upper foil portion is divided into a plurality of portions,
- wherein the lower foil portion includes an underlay foil portion including a first plate-shaped member that planarly supports part of the bearing surface of the upper foil portion;
- wherein the lower foil portion includes
- a first support foil portion disposed below the underlay foil portion and including a plurality of first support members,
- a pad foil portion disposed below the first support foil portion and including a second plate-shaped member corresponding to the first plate-shaped member, and
- a second support foil portion disposed below the pad foil portion and including a plurality of second support members;
- wherein the first plate-shaped member is supported by two first support members out of the plurality of first support members;
- wherein one first support member out of the two first support members is supported by one part of the second plate-shaped member and two second support members out of the plurality of second support members;
- and
- wherein the other first support member out of the two first support members is supported by a different part from the one part of the second plate-shaped member, one second support member out of the two second support members, and a different second support member from the two second support members.
