Abstract
A four-wheel-drive vehicle includes a driving source, main driving wheels, auxiliary driving wheels, a power transmitting member, a first mesh clutch, and a second mesh clutch. Meshing teeth on the driving source side of the first mesh clutch each have, along an entire tooth width thereof, an inclined surface in which a length in a rotational axis direction increases in a direction in which the meshing teeth on the driving source side rotate when the four-wheel-drive vehicle is traveling forward. The meshing teeth on the power transmitting member side of the first mesh clutch each have, along an entire tooth width thereof, an inclined surface in which a length in a rotational axis direction decreases in a direction in which the meshing teeth on the driving source side rotate when the four-wheel-drive vehicle is traveling forward.
