To reduce outbreak of a torque shock so as to reduce transmission loss of rotating force due to the torque shock in a power transmitting device mounted on an automobile.
This driving force transmitting mechanism 13 comprises a first gear MG1 capable of generating first rotating force, a second gear MG2 capable of generating second rotating force, a driving shaft DR for driving with transmission of the generated first rotating force or second rotating force, and a transmitting means CR capable of transmitting the first rotating force or the second rotating force to the driving shaft through a transmitting gear TG1 possible to be engaged with a first chain synchronously rotating with the first gear and possible to be engaged with a second chain 2 synchronously rotated with the second gear.
