To provide a lubrication structure of an automatic transmission which can perform excellent lubrication to a bearing to rotatably support an output gear.
A counter drive gear 17 forming the output gear is rotatably supported by a supporting cylindrical part 197 formed on an inner circumferential part of a disk part 196 of an intermediate bulkhead 195 formed in a transmission case 180 via a bearing 175, and a lubricating oil feed passage 197a is formed on the supporting cylindrical part 197. A lubricating oil return passage 196a is formed in the disk part 196, and a lubricating oil guide part 177 is formed by a front end of a nut 196 for a bearing and a labyrinth 72b formed in a clutch hub 72. The lubricating oil guide part 177 communicates with a lubricating oil feed passage 51 in an input shaft 50 through a division part, a lubricating oil passage 72e, a lubricating oil guide part 179, and a lubricating oil passage 51a.
