description Provided is a bearing structure that can support a rotary shaft with a small number of components. The bearing structure includes: a cylindrical sleeve (32) provided so as to surround the outer circumference of a rotary shaft (4) that rotates about a center axis line (CL) and configured to rotate together with the rotary shaft (4); thrust collars (34a, 34b) provided so as to abut against both ends in the center axis line (CL) direction of the cylindrical sleeve (32), respectively, having a larger diameter than the cylindrical sleeve (32), and configured to rotate together with the rotary shaft (4); and a compressor-side journal bearing (12) arranged on the outer circumference side of the cylindrical sleeve (32) and between the thrust collars (34a, 34b).
