PURPOSE:To improve power transmission efficiency by transmitting power through a forward direct-connecting gear without passing a toroidal speed change gear at the maximum speed of forwarding. CONSTITUTION:A toroidal type non-stage speed change gear is employed in an FF or an RR type automobile, and a forward direct-connecting gear 3 is provided on a way of an input shaft 2 connected to an engine 1. When the maximum speed condition is obtained in forwarding, a forward direct-connecting clutch 19 is actuated to make a forward clutch 15 and a backward clutch 16 non-actuating. Then power of the input shaft 2 is transmitted from the forward direct-connecting gear 3 to a gear 18 without passing a toroidal speed change unit 4 and more transmitted to a differential gear 21 through the forward direct- connecting clutch 19 and a transmission shaft 12. |
