Abstract

A carrier is provided with a circular plate section, a cylinder section, a planetary gear arrangement section, a first hydraulic fluid flow path, and a second hydraulic fluid flow path. The cylinder section has a second support section for supporting a support pin for a planetary gear, a first clutch attachment section for attaching to a first clutch, a second clutch attachment section for attaching to a second clutch, and a piston attachment section for attaching to a piston for driving the second clutch. The first hydraulic fluid flow path has a first inlet which is provided in the circular plate section to receive hydraulic fluid to lubricate the first clutch. The second hydraulic fluid flow path has a second inlet which is provided in the circular plate section to receive hydraulic fluid to drive the piston.
