Compressor
A compressor may include a hermetic case to store oil in a lower portion thereof, a compression mechanism part to compress a refrigerant, a power train part to generate a driving force, a rotational shaft to transmit the driving force generated from the power train part to the compression mechanism part and including a hollow portion and a female screw part formed at the hollow portion, and an oil pumping member inserted into the hollow portion of the rotational shaft and including an oil pumping part which moves the oil stored in the lower portion of the hermetic case up and a male screw part which is coupled to the female screw part of the rotational shaft. Since the oil pumping member and the rotational shaft are firmly coupled to each other, the reliability of the oil supplying is improved.
