Abstract
A control device of a continuously variable transmission for a vehicle to which power of a drive force source is input through a transmission path connecting/disconnecting device changes a gear ratio of the continuously variable transmission to a lower vehicle speed side during vehicle deceleration when the transmission path connecting/disconnecting device is in a power transmission interrupted state of interrupting power transmission through a power transmission path between the drive force source and the continuously variable transmission, earlier as compared to when the transmission path connecting/disconnecting device is in a power transmittable state enabling the power transmission, and the control device changes a gear ratio of the continuously variable transmission earlier to the lower vehicle speed side when vehicle deceleration is larger, when the transmission path connecting/disconnecting device is in the power transmission interrupted state.
