Rotary compressor and refrigeration apparatus

Abstract

A rotary compressor includes a compression mechanism, and a drive shaft configured to rotationally drive the compression mechanism. The drive shaft includes a main shaft portion, an eccentric portion eccentric with respect to an axis of the main shaft portion by a predetermined distance, and an oil passage including one or more oil holes extending in an axial direction. As viewed in the axial direction of the drive shaft, a predetermined direction in a region surrounded by a phantom envelope that envelops the one or more oil holes is a first direction, and a direction orthogonal to the first direction is a second direction. As viewed in the axial direction, the oil passage has a length in the first direction that is greater than a length in the second direction in the region surrounded by the phantom envelope.
