In a hermetic compressor having a vertical hole that communicates with the passage and is eccentric from the crankshaft center and opens above the crankshaft, the opening area S on the outlet side of the vertical hole is set to satisfy the following formula. Features: Hermetic compressor. S<Q2πrf×A However, when Lv/Lh>0.27, A=Lh/
When Lv, Lv/Lh≦0.27, A=1/0.
It is 27. In the formula, Q is the amount of lubricating oil flowing out from the outlet per unit time at an oil temperature of 100°C, r is the eccentricity of the outlet with respect to the crankshaft, Lh is the distance from the center of the crankshaft to the muffler, and Lv is the crankshaft. The difference in height between the outlet of the upper end of the pin portion and the upper end of the muffler, f, is the operating frequency of the crankshaft.
