る二軸回転体の漏出潤滑油排除構造。 Leakage that eliminates lubricating oil leaking from the seal portion of a two-shaft rotating body in which an outer rotating body and a receiving rotating body are supported so as to be relatively rotatable via a bearing, and a sealing member that seals the lubricating oil of the bearing is provided. In the lubricant oil removal structure, two of the seal members are provided with a space between them, and the passage outlet is set at a radius from the space so that the lubricant, etc. that communicate with the spaces of these seal members and leak out can be removed using centrifugal force. A structure for eliminating leaked lubricating oil for a biaxial rotating body, characterized in that a discharge passage provided on the outside in the direction is formed in the outer rotating body.
