Abstract
An automatic transmission () includes a planetary gear set (PS), first to third clutches (C-to C-), first to third brakes (B-to B-), and a counter gear () that outputs shifted rotation. The counter gear () is placed axially on one side of the planetary gear set (PS), and the second brake (B-) is placed axially on the opposite side from of the counter gear () from the planetary gear set (PS). The second brake (B-) that does not make higher speed rotation than other clutches and brakes can thus be separated from the planetary gear set (PS), and other clutches and brakes and the counter gear () are arranged near the planetary gear set (PS). Thus, members having a large thickness are reduced in length, whereby the automatic transmission is made compact and reduced in weight.
