Abstract

An automatic transmission is provided with a friction engaging element having a hub member, a drum member, friction plates disposed between the hub member and the drum member, and a piston configured to engage the friction plates. The hub member includes a first hub member made of ferrous material and having a cylindrical part provided with a spline part, the friction plates being spline-engaged with the spline part, and a second hub member made of aluminum-based material, disposed at a side part of the first hub member, and having a feed part for lubrication provided with a supply oil channel configured to supply hydraulic fluid for lubrication to the friction plates. A notch for lubrication is formed by circumferentially cutting the cylindrical part of the first hub member corresponding to the feed part of the second hub member. The feed part supplies the hydraulic fluid for lubrication through the notch.
