A drive apparatus for a hybrid vehicle includes: (a) a hybrid drive unit having (a-1) an automatic transmission, (a-2) a first rotating machine and (a-3) an engine connected to the first rotating machine through a hydraulically-operated connecting/disconnecting device; (b) an electric drive unit including a second rotating machine; and (c) a hybrid control device configured, in event of an anomaly that disables a shift control of the automatic transmission, to generate an electric power by causing the first rotating machine to be rotated by the engine and drive the hybrid vehicle to run by causing the second rotating machine of the electric drive unit to be operated with use of the generated electric power, in a state in which a power transmission through the automatic transmission is cut off and the connecting/disconnecting device is engaged.

An output shaft locking device for a multi-clutch transmission in which a plurality of rotational mechanisms, each of which is formed by arranging a clutch and a shifting mechanism is series, is provided in parallel between a rotational power input shaft and a rotational power output shaft, and an output shaft locking method. The output shaft locking device includes a locking control device which locks the rotational power output shaft by engaging a shifting gear in each of the shifting mechanisms of at least two of the rotational mechanisms, and engaging each of the clutches of the rotational mechanisms. Thus, it is possible to lock the output shaft so as to fix wheels by engaging the shifting gear without providing a lock mechanism.
