Claim:
1. A vehicle power transmission device comprising: a plurality of transmission units for transmitting rotation of an input shaft connected to a drive source to an output shaft, the transmission units arranged side by side between the input shaft and the output shaft, the transmission units each comprising: an input side fulcrum that has a variable amount of eccentricity from an axis of the input shaft and rotates together with the input shaft; a first one-way clutch connected to the output shaft; an output side fulcrum provided on an input member of the first one-way clutch; a connecting rod that has opposite ends thereof connected to the input side fulcrum and the output side fulcrum and moves back and forth; and a shift actuator that changes the amount of eccentricity of the input side fulcrum, wherein the input shaft comprises an input shaft main body portion connected to the transmission unit, and an input shaft upstream portion further on an upstream side in a power transmission direction than the input shaft main body portion, the output shaft comprises an output shaft main body portion connected to the transmission unit, and an output shaft downstream portion further on a downstream side in the power transmission direction than the output shaft main body portion, a clutch is disposed between the input shaft main body portion and the input shaft upstream portion, the clutch switching over a connecting state and disconnecting state therebetween, and in order to enable the input shaft upstream portion and the output shaft downstream portion to be integrally rotated even in the disconnecting state of the clutch, the input shaft upstream portion and the output shaft downstream portion can be connected to each other for operative association via an input rotating member provided on the input shaft upstream portion, an output rotating member provided on the output shaft downstream portion, and a power transmission member connecting the input rotating member and the output rotating member to each other.
