<p>In order to enable the installation of a sub-bearing of an electric motor by means of dual press-fitting, thus reducing the weight and facilitating assembly, an electric compressor (1) is equipped with: a compression unit (11) that compresses a cooling medium; an electric motor (12) linked to the compression unit (11) via a main shaft (14); a housing (2) in which the compression unit (11) and the electric motor (12) are housed; an end-side bearing support part (4c) provided near the end in the axial direction on the electric motor (12) side of the housing (2); and a rolling bearing (19), which has an outer ring (19a) press-fitted into the end-side bearing support part (4c) and an inner ring (19b) into which the end of the main shaft (14) is press-fitted, and which supports the main shaft (14). An aperture part (4e) is provided at the end face (4f) of the housing (2) near the end-side bearing support part (4c) to enable an assembly fixture for supporting the roller bearing (19) to be inserted and removed when the main shaft (14) is press-fitted into the inner ring (19b).</p> |
