<p><P>PROBLEM TO BE SOLVED: To provide an automatic transmission capable of reducing a friction loss. <P>SOLUTION: The automatic transmission includes a reduction gear mechanism 4, first and second two planetary gear mechanisms 6, 7, first and second two synchronous mesh mechanisms D1, D2, a first clutch CD1, a second clutch CD2, a third clutch Ca, and a fourth clutch Cb. The first planetary gear mechanism 6 has a first element Sm, a second element Rm, and a third element Cm. The second planetary gear mechanism 7 has a fourth element Rr, a fifth element Cr, and a sixth element Sr. The first element Sm and the fourth element Rr are connected to each other to constitute a connector Sm-Rr. The fifth element Cr is connected to an output member 3. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
