Abstract
A drive system includes a transmission mechanism that establishes a plurality of gear positions comprising a first-speed through sixth-speed gear positions and a reverse-drive gear position, by switching among change gear trains and coupling a first driveshaft to an output member, and also includes a lock clutch that switches a power distribution mechanism between a locked state in which a ring gear and a carrier are coupled to each other and are inhibited from rotating in a differential fashion, and a released state in which the inhibition of the differential rotation is cancelled.
