摘要： A work vehicle includes a hydrostatic continuously variable transmission to output power, an electric motor to perform shifting, a linkage mechanism to link a shifting shaft of the electric motor with a trunnion shaft of the hydrostatic continuously variable transmission the linkage mechanism, including a first linkage section linked with the shifting shaft, and a second linkage section linked with the trunnion shaft, and a biasing mechanism to press and bias a second gear of the second linkage section that meshes with a first gear of the first linkage section against the first gear such that a tooth flank of the second gear abuts with a tooth flank of the first gear in a rotation direction reverse to a rotation direction of the first gear.
