Abstract:
When an annular portion of a thrust collar rotates together with a rotating shaft member, centrifugal force and shear force, or differential pressure caused by difference in flow rate, for example, are generated in lubricating oil in a circulation oil chamber. With this, the lubricating oil in the circulation oil chamber is guided from the inner peripheral side to the outer peripheral side of the annular portion, through a circulation hole penetrating the annular portion. The flow of lubricating oil guided by the circulation hole forms a flow of lubricating oil from a lower oil chamber to an upper oil chamber through the circulation oil chamber. As a result, the lubricating oil stored in the lower oil chamber is circulated to the upper oil chamber through the circulation oil chamber, by rotation of the thrust collar.

Claim (Index 3):
The vertical bearing device according to  claim 1 , wherein:\n the casing forms, with an outer peripheral face of the annular part, an outer peripheral passage that allows passage of the lubricating oil; and a distance between the outer peripheral face and the casing that face each other and form the outer peripheral passage, is set larger above a border which is a virtual line obtained by extending the lower end of the circulation hole to the outer peripheral side toward the casing, than below the virtual line.
