Claims

[Scope of utility model registration request]

A cylindrical pump casing, the lower part of which is immersed in lubricating oil in an oil tank, is protruded downward from a bearing housing equipped with a bearing that supports a vertical rotating shaft. A cylindrical pump rotating body immersed in the lubricating oil in the oil tank is installed so as to be opposed to the inside of the pump casing, and the rotation of the pump rotating body causes the lubricating oil to be transferred to the pump casing. The oil is supplied to the bearing through an oil guide path provided in the oil tank and is circulated back into the oil tank, wherein the pump casing has an annular bottom wall portion facing the lower end of the pump rotating body and a pump. A guide member having a substantially L-shaped cross section and integrally having a cylindrical vertical wall portion located inside the pump rotating body and facing the inner circumferential surface of the pump rotating body is fixed to the lower part of the pump rotating body. 1. A bearing lubricating device for a rotating machine, characterized in that an oil passage hole is formed in a cylindrical vertical wall portion of the guide member through which lubricating oil in the oil tank can freely flow.
