Abstract

A compressor includes a shaft, a motor portion, and a compressor portion. The motor portion rotates the shaft. The compressor portion compresses refrigerant by rotation of the shaft. The motor portion has an upper insulator, a stator core, and a winding wire. The upper insulator has a plurality of insulator tooth portions. The stator core has a plurality of stator core tooth portions corresponding to the plurality of insulator tooth portions of the upper insulator. The plurality of stator core tooth portions of the stator core are respectively covered with a plurality of teeth of the upper insulator and are respectively wound around thereof by the winding wire. The insulator tooth portion of the upper insulator has a groove through which lubricant oil poured into the compressor portion passes on a stator core contacting surface which is in contact with the stator core tooth portion of the stator core.
