Abstract
An electric compressor includes a housing, a drive shaft, a motor, a movable scroll, and a fixed block. The fixed block is fixed to the housing and disposed between the motor and the movable scroll. The motor includes a stator and a rotor. The rotor has an introduction passage that is formed through the rotor in an axial direction of the drive shaft. The drive shaft includes a balance weight that is disposed between the fixed block and the motor and extends to a position where the balance weight covers at least a part of the introduction passage in a radial direction of the drive shaft in a view in the axial direction. The introduction passage includes a first passage located outward of the balance weight in a circumferential direction of the rotor and the drive shaft, and a second passage facing the balance weight in the axial direction.
