Beschreibung
Zusammenfassung:	The present invention provides a caulking tool, a manufacturing method of a caulking structure, and a manufacturing method of a compressor capable of preventing occurrence of stress concentration when two members are caulked and fixed to each other. A caulking tool includes a protrusion portion 31 which is formed in a columnar shape, a main body portion 32 which is disposed on a base end side of the protrusion portion 31 and is formed in a columnar shape having a larger diameter than that of the protrusion portion 31, a connection portion 35 which connects a base end of the protrusion portion 31 and the main body portion 32 to each other, in which an outer surface of the connection portion 35 is an R surface 35a which is annular about an axis O2 of the protrusion portion 31 and is formed in a recessed shape, and a surface of the main body portion 32 facing the protrusion portion 31 side is an inclined surface 32a which is smoothly continued to the R surface 35a and is inclined to a side separated from the protrusion 31 toward the outside in a radial direction of the protrusion portion 31.
