1. A scroll compressor comprising:
a casing;
a scroll compression mechanism disposed in the casing;
a motor disposed in the casing below the scroll compression mechanism, the motor including a stator and a rotor rotatable in a rotational direction;
a crankshaft connecting the scroll compression mechanism and the motor;
a bearing disposed below the motor, the bearing rotatably supporting the crankshaft;
a frame fixed to the casing, the frame supporting the bearing; and
an oil separation member fixed to the frame, the oil separation member being configured to suppress mixing of a refrigerant and a lubricating oil in the casing,
the frame having a first fixed leg fixed to the casing and a second fixed leg fixed to the casing,
the oil separation member having a first horizontal surface, a second horizontal surface, and a first inclined surface disposed between the first horizontal surface and the second horizontal surface, the first horizontal surface and the second horizontal surface being spaced apart by a first circumferential distance in a circumferential direction of the oil separation member,
the first inclined surface having a first inclined surface upstream portion and a first inclined surface downstream portion in the rotational direction,
the first inclined surface downstream portion being disposed higher than the first inclined surface upstream portion, and
the first horizontal surface, the first inclined surface, and the first fixed leg being disposed in order from upstream to downstream in the rotational direction.
