  • Patent number: 7578544
    Abstract: A pickup-style work vehicle comprises a front driver's seat, a backseat, a loading floor that is located rearwardly of the backseat and that can be moved to a dumping position, a loading floor size changeover mechanism, and a backseat posture change mechanism. The loading floor size changeover mechanism changes the size of the loading floor between a first state in which a front wall portion and a front bottom portion of the loading floor are moved forwardly in a fore-and-aft direction and a second state in which the front wall portion and the front bottom portion of the loading floor are moved rearwardly in a fore-and-aft direction. The backseat posture change mechanism changes a posture of the backseat between a first posture which is a non-use state and a second posture which is a use state. The fore-and-aft dimension of the backseat in the first posture is less than a fore-and-aft dimension of the backseat in the second posture.
