Zusammenfassung:In an automatic transmission, a connection member which connects a carrier of a planetary gear mechanism PGSa to a clutch hub of a clutch is made to abut on the carrier of the planetary gear mechanism PGSa in an abutting portion, a thrust bearing T2 is disposed between the connection member and a clutch drum of the clutch, a thrust bearing T1 is disposed between a transmission case and the clutch drum of the clutch, and a clearance between the thrust bearing T1 and the clutch drum of the clutch is adjusted by using a shim. Accordingly, a thrust load inputted from a sun gear Sb of a planetary gear mechanism PGSb can be transmitted to the transmission case without passing through a sun gear Sa, which rotates at a high speed, of the planetary gear mechanism PGSa, and friction loss is reduced.
