Document Type and Number:
Japanese Patent JP2022089231
Kind Code:
A
Abstract:
To inhibit complication of a structure of a gear case and introduce a lubrication oil into an outboard engine easily and quickly.SOLUTION: An outboard engine 1 includes: a drive shaft 9 which rotates in response to rotation of a driving shaft; a propeller shaft 10 which rotates in response to rotation of the drive shaft 9; a gear device 12 which transmits the rotation of the drive shaft 9 to the propeller shaft 10; a drive shaft housing 20 which houses the drive shaft 9; and a gear case 21 which expands to the side below the drive shaft housing 20 and houses the gear device 12. A lubrication oil is stored in the gear case 21. The propeller shaft 10 includes a portion housed in the gear case 21 and a portion exposed to the outside of the outboard engine 1. An interior of the propeller shaft 10 is formed with a lubrication oil passage 59 for circulating the lubrication oil between an interior of the gear case 21 and a space Z located outside the outboard engine 1.SELECTED DRAWING: Figure 3
