Abstract(English):

In the present invention, a first carrier of a first planetary gear is always coupled to an input member. A second rotational element of a fourth planetary gear is always coupled to an output member.A first ring gear of the first planetary gear, a second sun gear of a second planetary gear, and a first rotational element of the fourth planetary gear are always coupled. A second carrier of the second planetary gear and a third carrier of a third planetary gear are always coupled. A third ring gear of the third planetary gear and a third rotational element of the fourth planetary gear are always coupled. A first engagement element interconnects and disconnects any two among the second sun gear, second carrier, and second ring gear of the second planetary gear. A fourth engagement element interconnects and disconnects the second ring gear of the second planetary gear and a third sun gear of the third planetary gear.
