Abstract
A closed type scroll compressor has a drive shaft supported by a frame through bearings lubricated with a lubricating oil supplied from an oil reservoir via a lubricating oil passage bore formed in the drive shaft. The end of the drive shaft in which the upstream end of the lubricating oil passage bore opens is connected to the oil reservoir through a joint tube which is supported by supporting structures including a combination of a spherical slide bearing and slide bearing and capable of taking up any mounting error or displacement of the drive shaft in any direction. The compressor can be assembled easily without any risk of uneven or local contact of each sliding portion.
