To provide a camera system and a work vehicle that make it possible to check the front and sides of a lifted load.SOLUTION: An extending/shortening mechanism 7 includes: a flexible arm 71; a take-up roller 72 that takes up the arm 71; a feed roller 73 that feeds the arm 71 forward; and a fastener slider 74. The arm 71 includes an arm body 711 and a fastener 714 that can be opened and closed by the fastener slider 74. In a state where the fastener 714 is closed, a width of the fastener 714 is narrower than a width of the arm body 711. In a state where the fastener 714 is open, the arm body 711 has a flat plate shape; and in a state where the fastener 714 is closed, the arm body curves due to tension acting in a width direction.SELECTED DRAWING: Figure 17
【課題】持ち上げた荷物の前方及び側方を確認可能なカメラシステム及び作業車両を提供すること。【解決手段】伸縮機構7は、可撓性を有するアーム71と、アーム71を巻き取る巻取ローラ72と、アーム71を前方へ送り出す送出ローラ73と、ファスナスライダ74と、を備え、アーム71は、アーム本体711と、ファスナスライダ74により開閉可能なファスナ714とを備え、ファスナ714の幅は、ファスナ714を閉じた状態では、アーム本体711の幅より狭く、アーム本体711は、ファスナ714を開いた状態では、平坦な板状であり、ファスナ714を閉じた状態では、幅方向に張力が作用して湾曲する。【選択図】図17
