To prevent a front guard from being damaged when an operator makes an erroneous operation in which the front guard comes into contact with a part of a work vehicle.SOLUTION: A work vehicle includes: a vehicle body; a front guard attached to a front portion of the vehicle body; and a front loader which is attached to the front portion of the vehicle body and may move up or down. The front guard includes: a lower frame attached to the vehicle body; and an upper frame that is attached to the lower frame so as to be swingable around a shaft oriented in a vehicle body width direction and whose posture can be changed between a standing posture and a forward leaning posture by swinging with respect to the lower frame. The upper frame has: a vertical part that extends upward. An upper portion of the vertical part is provided with an upper curved portion that is curved backward as it goes upward. The upper curved portion has a first upper region that is located on a movement trajectory of a part of the front loader when the front loader is lowered while the upper frame is located in the forward leaning posture, and a second upper region that is curved forward as it goes downward from the first upper region.SELECTED DRAWING: Figure 18
【課題】フロントガードと作業車両の一部とが接触してしまう誤操作を行った場合にフロントガードの破損を防ぐ。【解決手段】車体と、車体前部に取り付けられるフロントガードと、車体前部に取り付けられて上昇又は下降可能なフロントローダとを備えた作業車両であって、フロントガードは、車体に取り付けられる下フレームと、下フレームに対して車体幅方向の軸回りに揺動可能に取り付けられ下フレームに対して揺動することにより起立姿勢と前傾姿勢とに姿勢変更が可能な上フレームとを有し、上フレームは上方に延びる縦部位を有し、縦部位の上部には上方に向かうにつれて後方に移行するように湾曲する上湾曲部が形成され、上湾曲部は、上フレームが前傾姿勢にある状態でフロントローダを下降したときに、フロントローダの一部の移動軌跡上に位置する第1上部位と、第1上部位から下方に向かうにつれて前方に湾曲する第2上部位とを有する。【選択図】図18
