PROBLEM TO BE SOLVED: To avoid a possibility in which a bonnet contacts a prime mover part in a closing operation of the bonnet.SOLUTION: A work vehicle comprises: a prime mover part 2 supported to a vehicle body frame 1; a bonnet 6 which can be oscillated vertically to a close position for covering the prime mover part 2 and an open position for opening the prime mover part 2; and a support frame 13 for supporting a free end side of the bonnet 6 on the close position. The bonnet 6 comprises: left and right guided parts 6A having a vertical length extended from a lower end portion of the bonnet 6 to an upper end side, on free end parts of left and right inside surfaces. The support frame 13 comprises left and right guide parts 13A positioned at a height same to a height of the upper end side of the prime mover part 2, and allowing centering of the bonnet 6 by contact to the left and right guided parts 6A during descent oscillation of the bonnet 6 to the close position. The left and right guided parts 6A have a left/right inclination surface 6a which serves as an action surface A for centering.SELECTED DRAWING: Figure 4 【課題】ボンネットの閉じ操作においてボンネットが原動部に接触する虞を回避する。【解決手段】作業車は、車体フレーム１に支持される原動部２、原動部２を覆う閉じ位置と原動部２を開放する開き位置とに上下揺動可能なボンネット６、及び、閉じ位置に位置するボンネット６の遊端側を支持する支持フレーム１３を備え、ボンネット６は、その左右の内側面の遊端部に、ボンネット６の下端部位から上端側にわたる上下長さを有する左右の被案内部６Ａを備え、支持フレーム１３は、原動部２の上端側と同じ高さに位置して、ボンネット６の閉じ位置への下降揺動時に、左右の被案内部６Ａとの接触によるボンネット６のセンタリングを可能にする左右の案内部１３Ａを備え、左右の被案内部６Ａは、センタリング用の作用面Ａとなる左右の傾斜面６ａを備えている。【選択図】図４
