Abstract

An electric compressor includes a compression unit that compresses a refrigerant, an electric motor that is coupled with the compression unit via a main shaft and a housing that accommodates the compression unit and the electric motor. The electric compressor further includes an end-side bearing holding part that is provided near an axial end of the housing closer to the electric motor and a rolling bearing that has an outer ring press-fitted into the end-side bearing holding part and an inner ring into which an end of the rotating shaft is press-fitted, and that supports the main shaft, in which an opening into which an assembly jig for supporting the rolling bearing when the main shaft is press-fitted into the inner ring can be inserted and removed is provided in an end surface of the housing near the end-side bearing holding part.
