Abstract
An electric compressor includes: a housing of an electric motor that is a power source of a compressor unit; a rotor that rotates inside the housing of the electric motor; a coil spring biasing the rotor in a rotation axis direction; a bearing interposed between the electric motor and the housing of the electric motor, and including an inner ring held by the rotor, and an outer ring biased by the coil spring to abut against an abutting portion of the housing of the electric motor; and a stopper that prohibits the rotor from displacing beyond a predetermined limit displacement amount against the biasing of the coil spring, and that allows the rotor to displace within the limit displacement amount. When the rotor is displaced to the limit displacement amount, the coil spring after being deformed has a closed height or more.
