Abstract
The present invention improves the drainability of lubricating oil at a thrust bearing. The present invention comprises: a rotating shaft; a thrust bearing that is provided to the rotating shaft and restricts the axial-direction movement of the rotating shaft; and an oil reservoir part () that has formed therein an oil reservoir space () that is provided to be adjacent to the thrust bearing in the axial direction and to open downward, the oil reservoir space () having formed therein an inclined surface () that, in a region that is in and below a horizontal plane H that passes through the center of the rotating shaft, protrudes to the thrust bearing side and is inclined along the rotational direction of the rotating shaft.
