Abstract
An inclined surface is formed in an upper inside wall of housing. The inclined surface inclines downwardly toward a lip seal. Lubricant oil supplied to the upper end of the inclined surface flows along the inclined surface without dropping downwardly due to surface tension, and flows to the lower end of the inclined surface then reaches the lip seal. Thus, the lubricant oil is supplied to the lip seal with certainty, thereby suppressing the wear of the lip seal and improving the durability of the compressor.
