To prevent shortening of the lifetime of a bearing which supports a drive shaft of an outboard engine caused by reduced lubricity caused by the temperature increase of a lubricating oil.SOLUTION: An oil introduction flow path 30 for causing a lubricating oil taken in from an outer peripheral side of a rotor 11 to flow to a drive shaft 3 side following rotation of the rotor is formed in the rotor 11 rotated integrally with the drive shaft 3 whose lower part is supported by a housing 1 via a bearing 5 and driven by an engine. The lubricating oil having flown through the oil introduction flow path 30 to the drive shaft 3 side is introduced into the bearing 5 to cool the lubricating oil in the bearing 5, thereby maintaining the lubricated state of the bearing 5 appropriate.SELECTED DRAWING: Figure 3
