PROBLEM TO BE SOLVED: To provide a transmission mechanism of a vehicle transmitting driving force from a driving source to a pair of steered wheels and a pair of non-steered wheels respectively disposed one side and the other side in a vehicular fore-and-aft direction, with a simple structure accelerating the pair of steered wheels according to a turning radius of the vehicle. SOLUTION: The transmission mechanism of the vehicle comprises: a variable hydraulic pump operationally coupled to the driving source; a steered wheel variable hydraulic motor and a non-steered wheel hydraulic motor structuring a closed circuit with the variable hydraulic pump; a pair of steered wheel driving axles; a differential device differentially transmitting rotation output from the steering wheel variable hydraulic motor to the pair of the steered wheel driving axles; a steering wheel driving axle case for storing the pair of the steered wheel driving axle and the differential device; and a steering mechanism operated by an operating device equipped near a driver's seat and rocking the steered wheels. The steered wheel variable hydraulic motor is supported by the steered wheel driving axle case, and an output adjusting member is interlocked with and linked to at least one of the steered wheels or the steering mechanism.
