ABSTRACT:
A starting apparatus formed by a torque converter is provided between an engine and a continuously variable transmission. A forward and reverse changeover apparatus is formed by a double pinion type planetary gear. Further, a reverse brake is disposed around a ring gear of the planetary gear and a forward clutch is mounted around the reverse brake. A lock-up clutch is provided near the forward clutch. A torque converter case encloses the torque converter, the forward and reverse changeover apparatus, the reverse brake, the forward clutch and the lock-up clutch therein. Since the planetary gear, the reverse brake and the forward clutch are arranged in the radial direction on substantially the same plane, the overall width of the continuously variable automatic transmission can be shortened and the number of components can be reduced.
