摘要： [Problem] To easily downsize an electric motor, to suppress a manufacturing cost, and to improve mountability on a hybrid-type traveling vehicle.
[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.

摘要： A transmission structure (1) of the present invention causes, during a period from a time point when a rotational speed of a drive rotational power reaches a predetermined first/second speed stage shift-up start speed until a first/second speed stage shift-up end time point, one of an input-side clutch mechanism pair and an output-side clutch mechanism pair to be in a double transmitting state, and causes, in the double transmitting state, a first clutch mechanism (60a; 80a) and a second clutch mechanism (60b; 80b) of the other one of the input-side clutch mechanism pair and the output-side clutch mechanism pair to be shifted to a disengagement state and an engagement state, respectively, while having frictional plate slid.
