Abstract
A sealing structure includes: a first member having a first surface extending along a gravity direction in which gravity acts; a second member having a second surface facing the first surface and extending along the gravity direction; a hydrostatic bearing that is arranged on the first surface of the first member and is configured to supply a compressed liquid between the first surface and the second surface; and a seal portion having a clearance that is formed between the first surface and the second surface and is provided below the hydrostatic bearing in the gravity direction. A liquid is retained in the clearance by surface tension.
