  • Patent number: 10245947
    Abstract: A vehicle includes an engine, a continuously variable transmission, a shiftable transmission, a switching lever, a shift rod, and an operation lever. The continuously variable transmission is located at a side of the engine. The shiftable transmission is located on the same side as the engine in a right-left direction with respect to the continuously variable transmission. The switching lever is located on the same side as the continuously variable transmission with respect to a center of the shiftable transmission in the right-left direction, and inputs a shifting operation force into the shiftable transmission. The shift rod is linked to the switching lever. The operation lever is operated by a driver seated on the seat to shift the shiftable transmission, and is linked to the shift rod.
