Zusammenfassung:To provide a work vehicle that is able to hold a horizontal position of a loading portion properly.SOLUTION: A work vehicle comprises: a vehicle body having a loading portion on which a load can be loaded; a plurality of traveling wheels located at front and rear positions on both left and right sides of the vehicle body; a support mechanism which is supported by the vehicle body and supports the plurality of traveling wheels so that their positions can be changed with respect to the vehicle body; an inclination detection unit which detects an inclined state of the vehicle body; and a control device which, based on the inclined state of the vehicle body, can control an operation of the support mechanism so that the loading portion is brought into a horizontal position. The control device is configured to calculate an inclination angle of a ground with which the plurality of traveling wheels are in contact. The work vehicle is configured not to control the operation of the support mechanism when the ground is inclined within a range of a preset inclination angle with the plurality of traveling wheels kept stopped and is configured to continue to control the operation of the support mechanism when the ground is inclined at the preset inclination angle or more with the plurality of traveling wheels kept stopped.SELECTED DRAWING: Figure 8 【課題】載置部の水平姿勢を適切に保持できる作業車を提供すること。【解決手段】荷物を積載可能な積載部を有する車両本体と、車両本体の左右両側における前後夫々に位置する複数の走行車輪と、車両本体に支持されるとともに複数の走行車輪を車両本体に対して位置変更可能に支持する支持機構と、車両本体の傾斜状態を検出する傾斜検出部と、車両本体の傾斜状態に基づいて積載部が水平姿勢になるように支持機構の動作を制御可能な制御装置と、が備えられている。制御装置は、複数の走行車輪が接地する地面の傾斜角を算出可能に構成され、かつ、複数の走行車輪が停止した状態で地面が予め設定された設定傾斜角の範囲内で傾斜している場合に支持機構の動作を制御せず、複数の走行車輪が停止した状態で地面が設定傾斜角以上に傾斜している場合に支持機構の動作を制御し続けるように構成されている作業車。【選択図】図8
