[Task] In an electric scroll compressor which includes a housing member in which a motor fixing portion and an end plate are integrated with each other, and in which a thrust load of a swing scroll is supported by the end plate, deformation of the end plate decreases.;[Solution] In an electric scroll compressor in which stator contact portions 61 which come into contact with a stator 41 of an electric motor 4 and stator non-contact portions 62 which do not come into contact with the stator are alternately disposed in a circumferential direction on an inner circumferential wall of a motor fixing portion 6a, a hole 63 is provided at a position of the end plate 6b corresponding to each of the stator contact portions 61 in an axial direction, and a disadvantage in which the end plate 6b is deformed due to the motor fixing portion 6a being deformed to increase the diameter, is prevented. In addition, a reinforcing rib 65 reinforcing the end plate 6b is provided at a position of the end plate 6b corresponding to each of the stator non-contact portions 62 in the axial direction, and deformation of the stator contact portion 61 influencing the end plate 6b via the reinforcing rib 65 is prevented. |

1. An electric scroll compressor, comprising:
a housing member; a compression mechanism which is accommodated in the housing member , and in which a fixing scroll having a substrate and a spiral wall and a swing scroll having a substrate and a spiral wall mesh with each other to form a compression chamber; a drive shaft by which the swing scroll is revolved; a rotation preventing mechanism which prevents rotation of the swing scroll; and an electric motor which is accommodated in the housing member and rotates the drive shaft, wherein the electric motor includes a rotor which is fixed to the drive shaft and a stator which excites and drives the rotor, wherein in the housing member, a motor fixing portion to which the electric motor is fixed, and an end plate which supports an axial load of the swing scroll and rotatably supports the drive shaft are integrally formed, wherein stator contact portions which come into contact with the stator and stator non-contact portions which do not come into contact with the stator are alternately disposed in a circumferential direction on an inner circumferential wall of the motor fixing portion, and wherein a hole, which is formed on a position corresponding to each of the stator contact portions in an axial direction and penetrates the end plate in the axial direction, is provided on the end plate. |
