To provide a driver's seat structure of a work vehicle in which the change between a horizontal posture and a forward tilted posture of a seat can easily be performed by a supporting tool without erroneous operation.SOLUTION: A driver's seat structure of a work vehicle includes a supporting tool 6 for supporting a turning base frame 9a of a seat 2 in a vertically turning manner on a support shaft 11 of a seat base frame 4, and turning a locking shaft 26 of the turning base frame 9a in the longitudinal direction by using an operating shaft 5a provided at the rear of the seat base frame 4 as a supporting point, in which a horizontally locking groove 25b and a slope locking groove 25c formed in the supporting tool 6 are alternatively locked to the locking shaft 26. A support mechanism 5 comprising the locking shaft 26 and the supporting tool 6 and the like is arranged on the side of the seat 2.SELECTED DRAWING: Figure 2
【課題】シートの水平姿勢と前傾姿勢の変更を、支持具によって誤操作なく行い易くすることができる作業車両の運転座席構造を提供する。【解決手段】シート2の回動ベース枠9aをシートベース枠4の支持軸11に上下回動自在に支持し、回動ベース枠9aの係止軸26をシートベース枠4の後部に設ける操作軸5aを支点に前後方向に回動する支持具6を備え、該支持具6に形成する水平係止溝25bと傾斜係止溝25cとを係止軸26に択一的に係止する作業車両の運転座席構造であって、前記係止軸26と支持具6等からなる支持機構5を、シート2の側方に配置した。【選択図】図2
