A main clutch is disposed radially outward on a differential mechanism. There is no need to reserve space to install the main clutch at the end of the differential mechanism opposite from a differential case. Thus, the axial length of an LSD can be reduced, providing easier installation in the vehicle. Also, the LSD is installed in the vehicle to the rear of a transmission. This location provides spatial leeway in the radial direction. As a result, ease of installation is maintained if the main clutch is disposed radially outward from the differential mechanism and the outer diameter of the LSD is increased. The present invention provides a drive force transmission device with reduced axial length, thereby improving ease of installation.
