Abstract
A compressor includes a housing, a rotary shaft, a pulley, an electric motor, a pulley one-way clutch, and a motor one-way clutch. The shaft is rotatably supported by the housing. The pulley is operably connected to the shaft and includes a power transmission portion. When power is transmitted from a vehicular engine to the power transmission portion, the pulley is rotated. The electric motor rotates the shaft and includes a rotor, which is operably connected to the shaft. At least part of the electric motor overlaps the power transmission portion in the axial direction of the shaft. The pulley one-way clutch is located between the pulley and the shaft and selectively permits and prevents power transmission between the pulley and the shaft. The motor one-way clutch is located between the rotor and the shaft and selectively permits and prevents power transmission between the rotor and the shaft.
