Abstract
A transmitting apparatus includes a disengaging device that disengages a driving force from a front-wheel differential device to a first driving-force transmitting direction converting unit and a multi-plate clutch mechanism provided between an output of a rear-wheel differential device and a right-rear wheel and capable of successively adjusting a fastening force. Drag torque when the fastening of the multi-plate clutch mechanism is released is set smaller than friction torque of a rear-wheel drive system between the first driving-force transmitting direction converting unit and a second driving-force transmitting direction converting unit. A controller unconnects the disengaging device and releases the fastening of multi-plate clutch mechanism when switching to a two-wheel drive mode, thereby stopping the rotation of the rear-wheel drive system.
