Abstract: PROBLEM TO BE SOLVED: To feed an oil stably to a bearing of a crankshaft or a sliding section of a compressor mechanism when a compressor is in operation without increasing an oil sealing amount.
SOLUTION: Steps are formed at the bottom section of an oil sump 4 to form the deepest section, and an oil intake port 10 is arranged right above the deepest section of the oil sump 4. This can facilitate reservation of oil 5 in the oil sump 4 even when the oil 5 is pressed to a wall surface in a hermetic container 6 by centrifugal force by rotation of the crankshaft 1 since the bottom section of the oil sump 4 is in the stepped shape. Consequently, it can reduce the oil sealing amount and enable stable oil feeding to the bearing 9 of the crankshaft 1 or the sliding section of the compressor mechanism 7 during operation.
