Abstract: A speed-reducing gear unit is provided for causing a reduced-speed rotation output member to have a reduced rotation that is slower than rotation of an input shaft. The reduced-speed rotation output member is switched between a reduced-speed rotation state and a free rotation state by rotation state switching means. The reduced-speed rotation of the reduced-speed rotation output member is selectively transferred to fourth and first elements of a speed-changing dual planetary gear unit via first and third control clutches. The rotation of the input shaft is transferred to a second element via a second control clutch. Rotations of the first and second elements are selectively restricted by first and second control brakes. A third element is connected to an output shaft.
