To reduce torque fluctuation by compensating an influence of torsion of an output shaft in a vehicle power-transmission device in which a plurality of transmission units are axially arranged.
In a vehicle power-transmission device, when an input shaft 12 connected to a driving source rotates, an eccentric disc 19 of a transmission unit 14 eccentrically rotates, and when a connecting rod 33 whose one end is connected to the eccentric disc 19 reciprocates, an output shaft 13 intermittently rotates through a one-way clutch 36 to which the other end of the connecting rod 33 is connected. The influence of torsion of the output shaft 13 causes the amount of torque transmission of the one-way clutch 36 at one end of the output shaft 13 for outputting driving force to be increased and the amount of torque transmission of the one-way clutch 36 at the other end of the output shaft 13 to be decreased. However, the rigidity of an outer member 38 of the one-way clutch 36 is set to be sequentially higher from the one end toward the other end of the output shaft 13, and thereby each amount of torque transmission of the one-way clutch 36 is made uniform and torque fluctuation can be reduced.
