To surely protect a vehicle body from impact applied from a front and upper side.SOLUTION: A front guard of a work vehicle comprises a lower frame that is mounted on a vehicle body and an upper frame which is mounted slidably around a shaft in a vehicle body width direction with respect to the lower frame and arranged at a front side of a bonnet. The lower frame has a first lower member that is arranged near one side in the front side of the vehicle body and a second lower member that is arranged near the other side. The upper frame has a first extending part that extends upward from one side of the first lower member, a second extending part that extends upward from the other side of the second lower member, and a connection part that connects an upper end of the first extending part to an upper end of the second extending part. The connection part has one site connecting to the first extending part, the other site connecting to the second extending part and an intermediate site connecting the one site to the other site. The one site transfers forward as going from the first extending part side toward the intermediate site side, the other site transfers forward as going from the second extending part side toward the intermediate site side, and the intermediate site is extended in a vehicle body width direction to connect the one site to the other site.SELECTED DRAWING: Figure 1
【課題】前上方から加わる衝撃から車体を確実に保護する。【解決手段】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てボンネット前方に配置される上フレームとを備え、下フレームは、車体前方における一側方側に配置される第1下部材と、他側方側に配置される第2下部材とを有し、上フレームは、第1下部材の一側方側から上方に延びる第1延伸部と、第2下部材の他側方側から上方に延びる第2延伸部と、第1延伸部の上端と第2延伸部の上端とを連絡する連絡部とを有し、連絡部は、第1延伸部と連絡する一方部位と、第2延伸部と連絡する他方部位と、一方部位と他方部位とを繋ぐ中間部位とを有し、一方部位は第1延伸部側から中間部位側に向かうにつれて前方に移行し、他方部位は第2延伸部側から中間部位側に向かうにつれて前方に移行し、中間部位は車体幅方向に延びて一方部位と他方部位とを繋いでいる。【選択図】図1
