Abstract
A compressor is configured to compress a refrigerant and use a lubricating oil. The compressor includes a compression mechanism configured to compress the refrigerant, a driving shaft configured to rotate about a rotation axis in order to drive the compression mechanism, a slide bearing slidably supporting the driving shaft, a first surface fixed to the driving shaft and intersecting with a line arranged in parallel to the rotation axis, a second surface facially abutted to the first surface, and a recovery space formed in the compressor. The recovery space is configured and arranged to recover the lubricating oil leaking out of bottom ends of sliding surfaces of the slide bearing and the driving shaft. The first surface and the second surface respectively continue to surfaces forming the recovery space.
