Abstract

A compressor includes an actuator, a compression mechanism, a drive shaft, a support, a casing, and a welding pin. The drive shaft transmits a driving force of the actuator to the compression mechanism. The support supports a bearing that rotatably supports the drive shaft. The support has at least one hole formed in an outer surface. The casing has a cylindrical shape and accommodates the drive shaft and the support. The welding pin is press-fitted into the hole of the support and is welded and fixed to the casing. A low rigidity region is provided at at least a part of a periphery of an adjacent portion adjacent to the hole of the support. The low rigidity region has lower rigidity than the adjacent portion. The low rigidity region includes a thin portion having a smaller thickness in a radial direction of the casing than the adjacent portion.
