PROBLEM TO BE SOLVED: To provide a caster wheel capable of preventing horizontal shaking of a movable body when the direction of travel of the movable body is reversed, and a work vehicle provided with the caster wheel.SOLUTION: In the caster wheel in which the rotary shaft position Q2 of a wheel 22 is offset with respect to a caster arm 21 in a horizontal direction, the rotary shaft position Q2 of the wheel 22 is offset with respect to the shaft center Q1 of the caster arm 21 in a horizontal direction, a shaft leg 23 offset against the rotary shaft position Q2 of the wheel with respect to the caster arm 21 is provided, and the shaft leg 23 is attached to a vehicle body frame 11 on a follower wheel 2 side of a work vehicle 1 in a freely rotatable manner through a bearing 24. An offset amount W1 between the rotary shaft position Q2 of the wheel 22 and the shaft center Q1 of the caster arm 21 and an offset amount W2 between the shaft center Q1 of the caster arm and a shaft center Q3 of the shaft leg 23 are set to the same level.SELECTED DRAWING: Figure 8

    【課題】移動体の進行方向が反転する際における移動体の横ぶれを防止することができるキャスタ・ホイール及び該キャスタ・ホイールを備えた作業車両の提供。【解決手段】キャスタアーム21に対し車輪22の回転軸位置Q2が水平方向にオフセットしたキャスタ・ホイールにおいて、キャスタアーム21の軸心Q1に対し車輪22の回転軸位置Q2が水平方向にオフセットし、キャスタアーム21に対し車輪の回転軸位置Q2とはオフセットした軸脚23を備え、該軸脚23を作業車両1の従動輪2側の車体フレーム11に対しベアリング24を介して回転自在に取り付けられている。車輪22の回転軸位置Q2とキャスタアーム21の軸心Q1とのオフセット量W1と、キャスタアームの軸心Q1と軸脚23の軸心Q3とのオフセット量W2が同一に設定されている。【選択図】図8
