れたことを特徴とする自動変速機の潤滑構造。 The drum brake has a planetary gear mechanism, and is provided with a drum brake for restraining one element of the planetary gear mechanism, and the drum brake includes a disk whose inner circumference is connected to the element of the planetary gear mechanism, and It consists of a brake drum provided on the outer periphery of the disk so as to protrude to one side in the axial direction, and a brake band arranged to be coupled to the outer periphery of the brake drum, and the disk has needle bearings on both axial sides. In a lubrication structure for an automatic transmission in which lubricating oil is supplied to the needle bearing from the transmission shaft side, the disk has a curved portion curved in the same direction as the drum at a radially intermediate portion thereof. A lubricating oil passage passing through the disk in the thickness direction is formed in a radially outer portion of the curved portion, and the lubricating oil flowing along the disk surface via the needle bearing is directed to the inner surface of the brake drum. Lubricating oil for an automatic transmission, characterized in that the brake drum is formed with a lubricating oil hole that penetrates the drum in the thickness direction and guides lubricating oil from the inner surface to the outer surface. structure.
