Work vehicle

A work vehicle, comprising:

• 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, which 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;
• wherein
• the biasing mechanism includes:
• a swing arm swingable together with the trunnion shaft;
• and
• an operation body swingable around an axial center parallel or substantially parallel to an axial center of the trunnion shaft;
• the swing arm includes a cam;
• the operation body includes a cam follower;
• the biasing mechanism further includes a biasing spring to bias the cam follower toward the cam;
• and
• the swing arm is swingable in a swinging direction causing the tooth flank of the second gear to approach the tooth flank of the first gear, in response to the biasing spring and the cam follower pressing the cam.
