Abstract:
1. A working vehicle comprising: a continuously variable transmission apparatus, serving as a traveling drive system of the working vehicle, structured such as to combine a hydraulic continuous variable transmission apparatus and a gear mechanism so as to output a rotational power from an engine while changing speeds, wherein said continuously variable transmission apparatus comprises: a transmission shaft extending below said hydrostatic transmission housing and entering said transmission case to transmit power to said gear mechanism in said transmission case from the engine, wherein said gear mechanism includes an output portion, transmits a part of said rotational power of said transmission shaft to said hydraulic pump, and transmits a remaining part of said rotational power of said transmission shaft to said output portion, and wherein said hydraulic motor outputs an additional rotational power to said output portion of said gear mechanism driven by said remaining part of said rotational power of said transmission shaft.
