Abstract
A transmission for a hybrid vehicle includes a planetary gear set including at least three rotary members of which one is connected to an engine. A first anti-rotator selectively restricts rotation of the rotary member connected to the engine. A first motor generator is connected to another one of the rotary members of the planetary gear set. A second motor generator is connected to the remaining one of the rotary members of the planetary gear set. An output shaft has a first output gear thereon, which is externally engaged with the rotary member connected to the first motor generator. A second anti-rotator selectively restricts rotation of the rotary member connected to the second motor generator.
