Abstract
Provided is a power transmission device that can increase a torque that a second motor outputs to an output shaft. The power transmission device includes: a first input shaft and a second input shaft coupled to a first motor and a second motor, respectively, and disposed on the same axis; a first speed reduction mechanism transmitting a rotation of the first input shaft to an output shaft via an intermediate shaft; a second speed reduction mechanism transmitting a rotation of the second input shaft to the output shaft via the intermediate shaft at a speed reduction ratio different from the speed reduction ratio of the first speed reduction mechanism; and a first clutch disconnecting or connecting the power of the first speed reduction mechanism.
