Abstract
A compressor includes a casing having a tubular barrel, a fixation target member housed in the casing and fixed to the barrel, and a plurality of welds provided in a circumferential direction of the barrel. The welds connect the barrel and the fixation target member to each other. The fixation target member is a support configured to rotatably support a compression mechanism configured to compress a refrigerant or a drive shaft connected to the compression mechanism. An inner diameter of the barrel and an outer diameter of the fixation target member in a rated operating state of the compressor being in a fit relationship in which a combination of a tolerance class for a hole and a tolerance class for a shaft (hole/shaft) defined in ISO 286 corresponds to H8/f7, F8/h9, H7/f7, F8/h6, H7/g6, or G7/h6.
