Abstract:
A lubricating oil passage portion that constitutes a cooling portion is exposed to the outside from a casing. Lubricating oil having absorbed heat of a thrust bearing portion and a journal bearing portion is cooled in the cooling portion, when the lubricating oil moves from an upper oil chamber to a lower oil chamber while circulating by use of gravity. Thus, the circulating lubricating oil prompts cooling of the heated thrust bearing portion and journal bearing portion. Additionally, the lubricating oil passage portion of the cooling portion is provided integrally with the casing, on the radially outer side of the casing. For this reason, the cooling portion does not require long piping.

Claim (Index 3):
The vertical bearing device according to  claim 1 , wherein:\n the casing partitions the oil chamber not only into the upper oil chamber and the lower oil chamber, but also into a circulation oil chamber that allows passage of the lubricating oil circulating from the lower oil chamber to the upper oil chamber by rotation of the thrust collar rotating together with the rotating shaft member; and the thrust bearing part and the journal bearing part are provided in the circulation oil chamber.
