Claim 11:
12. A scroll compressor comprising:
a casing that defines an oil storage space;
a fixed scroll disposed inside the casing;
an orbiting scroll disposed at a first side of the fixed scroll and configured to perform an orbiting motion relative to the fixed scroll, wherein the orbiting scroll and the fixed scroll define a compression chamber therebetween; and
a main frame disposed opposite to the fixed scroll with the orbiting scroll being disposed between the main frame and the fixed scroll,
wherein at least one of the main frame or the fixed scroll defines a gas drain hole configured to guide gas in the oil storage space to thereby discharge the gas out of the casing,
wherein the gas drain hole comprises:
an upper communication portion that passes through an upper surface of the main frame,
a lower communication portion that is in fluid communication with the oil storage space and configured to guide the gas in the oil storage space to the upper communication portion, and
a middle communication portion that extends through an upper portion of the main frame in a direction crossing the upper communication portion, the middle communication portion connecting the lower communication portion to the upper communication portion.
