A compressor is provided to prevent introduction of impurities such as metal chips generated by friction between a rotation shaft and a bearing into an oil path, thereby making operation of the compressor smooth and preventing noise. A compressor includes a bank part(390) formed with a groove by a predetermined section for collecting oil passing on a rotation shaft(330) partially with impurities. A communication part(400) is formed on a curved surface at a lower part of the rotation shaft connected to a lower part of the bank part, for discharging the collected impurities. The communication part is formed by carrying out edge grinding or die casting for the curved surface at a lower part(330b) of the rotation shaft. The communication part is positioned part from an oil path(360) or an oil discharge hole by a predetermined angle.
