A hermetic compressor may include a frame, a crankshaft, and an oil pump. The crankshaft may be rotatably mounted to the frame. The oil pump may be mounted to a lower portion of the crankshaft to be rotatable together with the crankshaft. The oil pump may pump oil from a lower region to an upper region of a shell using centrifugal force. The crankshaft may be provided with a hollow hole therein that is inclined in two directions with respect to an axial direction of the crankshaft. This may result in increasing a dynamic pressure for scattering the oil to the upper region of the shell and an oil supply amount.
