<p>PROBLEM TO BE SOLVED: To reduce friction loss by transmitting a thrust load generated by a gear of an automatic transmission to a transmission case so that the load goes through bearings as little as possible.SOLUTION: A connection member 21 for connecting a carrier Ca of a planetary gear mechanism PGSa to a clutch hub 22 of a clutch C1 is butted against the carrier Ca of the planetary gear mechanism PGSa by a butt portion 51, a thrust bearing T2 is arranged between the connection member 21 and a clutch drum 23 of the clutch C1, a thrust bearing T1 is arranged between the clutch drum 23 of the clutch C1 and a transmission case 19, and a clearance between the thrust bearing T1 and the clutch drum 23 of the clutch C1 is adjusted by a shim 52. As a result, a thrust load input from a sun gear Sb of a planetary gear mechanism PGSb can be transmitted to the transmission case 19 so as not to go through a sun gear Sa of the planetary gear mechanism PGSa which rotates at a high speed.</p> |
