VEHICLE

[Problem] To easily downsize an electric motor, to suppress a manufacturing cost, and to improve mountability on a hybrid-type traveling vehicle. [0002] [Solution] A traveling vehicle of the present invention is configured such that an internal combustion engine, a main drive wheel, and a sub drive wheel are supported on a traveling machine body, and the internal combustion engine drives the main drive wheel through a traveling transmission mechanism. An electric motor and a planetary gear mechanism are provided inside an axle case which supports the sub drive wheel. In three elements of the planetary gear mechanism, a first element is interlockingly connected to the electric motor, a second element is interlockingly connected to the sub drive wheel, and a third element is interlockingly connected to an output side of the traveling transmission mechanism.
