    An enclosed rotary compressor and freezing air conditioning unit. A closed rotary compressor can increase a reliability by preventing defective lubrication due to shortage of the oil amount supplied to the sliding parts of a compression mechanism. The compression mechanism and a lubricating mechanism are stored in a closed container 6 having lubricating oil 16 stored therein. The compression mechanism comprises a roller part 81a revolving in a cylinder chamber 51a and a vane part 81b partitioning the cylinder chamber 51a. The lubricating mechanism comprises an oil supply pump chamber 51c formed on the outside of the cylinder chamber 51a and the tip part of the vane part 81b reciprocating in the oil supply pump chamber 51c. The tip part of the vane part 81b is formed so that the oil supply pump chamber 51c is made wider toward a supply oil flow direction.
