In this vehicular power transmission device comprising a crank-type continuously variable transmission, by engaging a second one-way clutch (69) when the vehicle shifts to a deceleration traveling state, an engine brake can be actuated by reversedly transmitting a drive force to an engine (E) via an auxiliary drive-force transmitting means (54). At this time, depending on the magnitude of the differential rotation of the second one-way clutch (69) before engagement, there are differences in time lag until the second one-way clutch (69) is engaged; however, the rotation of an input shaft (12) is braked or assisted by a drive force of an electric motor (24) of a speed-change actuator (23), which changes the speed-change ratio of the continuously variable transmission (T), in a manner such that the time until said differential rotation reaches zero matches a predetermined time that has been set in advance. Thus, the time lag until the engine brake is actuated can be made uniform, and the sense of incongruity felt by the driver can be eliminated.
