To provide a rotary compressor device that reliably reduces sliding loss generated on an eccentric part of a crankshaft and on an inner circumference of a roller, and has superior reliability and durability.
The rotary compressor device is stored in a sealed container 1 where an electric motor 2 is connected to a compression mechanism 3 by the crankshaft 31. The compression mechanism 3 includes: a cylinder 30; a compression chamber 39 which is formed by an upper bearing 34 and a lower bearing 35 blocking both end faces of the cylinder 30; the roller 32 which is fitted to the eccentric part 31a of the crankshaft 31 installed in the cylinder 30; and a vane 33 which follows an eccentric rotation of the roller 32 and reciprocates in a slot provided in the cylinder 30, thereby separating the compression chamber 39 into a low and high pressure parts. In the device, a relief 42 is established on the eccentric part 31a in a tilting direction during an operation of the crankshaft 31.
