<p>Provided is an automatic transmission for a vehicle for which the processing is simple during the manufacturing stage. Clutches (C1-C6) do not include an object (a brake) that, by means of engagement, directly connects with the sun gears (S), carriers (CA), and ring gears (R) of planetary gear devices (22, 24, 26), which are elements that rotate with respect to a transmission case (28); in addition, all of the multiple gear ranges that can be established with an automatic transmission (10) and the like by means of the combinations of engagements and disengagements of the multiple clutches (C1-C6) can be established selectively. Therefore, manufacturing by means of simple processing is possible, without the necessity of forming a brake groove on the inner-circumferential side of the transmission case (28). In other words, it is possible to provide an automatic transmission (10) for a vehicle for which the processing is simple during the manufacturing stage.</p> |
