The invention provides a vehicular power transmission device. The vehicular power transmission device is provided with a clutch which can cut off power transmission and is arranged between a driving source and a crank type speed change mechanism, and unexpected driving force transmission due to the connection of the clutch is prevented. When the input shaft (11A) of a transmission is fixed and cannot rotate, the connection of the clutch (52) is relieved, the output shaft (11B) of the driving source is separated from the input shaft (11A) of the transmission, the driving force of the driving source (E) is transmitted from the output shaft (11B) of the driving source to the output shaft (12B) of the transmission through an auxiliary power transmission unit (29), thus, the vehicle can keep out of the way and travel to a repair factory by means of the driving force of the driving source (E). A clutch control unit (60) which controls the connection and the disconnection of the clutch (52) controls the clutch (52) to be switched from the disconnection state to the connection state when a one-way clutch (21) of the crank type speed change mechanism (U) is in a disconnection state, thus, the case that when the clutch (52) is connected, the driving force is transmitted to a driving wheel (W) unexpectedly can be reliably prevented.
