WORK VEHICLE

To provide a work vehicle which allows either an operation member installed at a position other than the position of an operation lever or the operation lever to be used for operating a link mechanism mounted with a work device in a manner that prevents the operation member from being moved while the operation lever is used.SOLUTION: An additional operation mechanism comprises a first rotary shaft, a second rotary shaft, a first engagement member, an operation member, a second engagement member and an energization member. The first engagement member is mechanically connected to an operation lever and can be rotated around the first rotary shaft following the movement of the operation lever. The operation member is slidable in an axial direction of the second rotary shaft and is operated by an operator. The second engagement member is configured to be slidable in the axial direction together with the operation member, rotatable around the second rotary shaft and be engaged with the first engagement member so as to rotate the first engagement member. The energization member moves the second engagement member away from the first engagement member in the axial direction so that the second engagement member does not undergo engagement with the first engagement member.SELECTED DRAWING: Figure 11 【課題】操作レバーの位置以外の場所に設けられた操作部材と操作レバーとのいずれでも作業装置が装着されるリンク機構を操作できる作業車両において、操作レバーが操作される際に当該操作部材が動かないようにする。【解決手段】付加操作機構は、第１回転軸と、第２回転軸と、第１係合部材と、操作部材と、第２係合部材と、付勢部材と、を備える。第１係合部材は、操作レバーと機械的に接続され、操作レバーの移動に応じて第１回転軸周りに回転自在である。操作部材は、第２回転軸の軸方向に摺動可能で、オペレータに操作される。第２係合部材は、操作部材とともに軸方向に摺動可能で、第２回転軸周りに回転自在で、第１係合部材に係合して第１係合部材を回転させるように構成される。付勢部材は、第２係合部材を第１係合部材と係合しないように第２係合部材を第１係合部材から軸方向に離間させる。【選択図】図１１
