Abstract: A scroll compressor has a drive shaft which drives a scroll compression mechanism housed in a housing and a drive shaft support member which supports the drive shaft. The drive shaft support member includes a plate portion having a predetermined thickness in an axial direction of the drive shaft. One side end surface of the plate portion has thereon a sliding support surface which supports the sliding movement of an orbiting scroll. Another side end surface of the plate portion has formed thereon a protruding portion which, protruding toward the other side in the axial direction, is fitted onto an inner peripheral surface of the housing. The protruding portion is interference fitted onto the inner peripheral surface of the housing, and thereby the drive shaft support member is fixed to the housing.

Abstract: An electric compressor (7) includes a compression mechanism (3); an electric motor (2) driving the compression mechanism (3), the electric motor having an axis of rotation (X); and an electric motor (2) power supply inverter (1), the inverter (1) being mounted in an inverter housing (10). The compression mechanism (3) is mounted in a compression housing (30), and the electric motor (2) is mounted in a motor housing (20) extending longitudinally along the axis of rotation (X) and having a first end (20P) connected to the inverter housing (10) by a plurality of securing devices (5) extending inside the motor housing (20). The motor housing (20) includes a second end (20S) located opposite the first end (20P) in relation to the electric motor (2) and connected to the compression housing (30) by a plurality of securing devices (6) different from the above-mentioned securing devices (5).

Abstract: In a scroll compressor, breakage of a spiral end portion of a spiral wall (10c, 11c) of a scrolls is prevented. [Solving means] In a scroll compressor including: a fixed scroll (10) including an end plate (10a) and a spiral wall (10c) extending upright from the end plate (10a); an orbiting scroll (11) including an end plate (11a) and a spiral wall (11c) extending upright from the end plate (11a); and a drive shaft (8) configured to transmit a rotational power to the orbiting scroll (11), and configured to compress a compressed fluid by an orbital motion of the orbiting scroll (11), an extending portion (113) which does not come into contact with the spiral wall (10c) of the fixed scroll (10) is provided so as to extend from a spiral end portion (112), which corresponds to a terminal end of a wall surface (compression forming portion (111)) which forms a compression chamber (15) on a spiral wall (11c) of the orbiting scroll (11).

Abstract: [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.
