PROBLEM TO BE SOLVED: To provide a work vehicle including a structure that reduces thermal influence in an engine room.SOLUTION: A work vehicle of the invention covers an engine 5 mounted at a front part of a travel machine body 2, a cooling fan 59 for air-cooling the engine 5, and a fan shroud 234, which encloses the cooling fan 59, with an engine hood 6. The cooling fan 59 is disposed at a front surface side of the engine 5 and cooling air is taken from a front grille formed on a front surface of the engine hood 6 into a space defined by the engine hood 6 by driving the cooling fan 59. In the engine hood 6, opening holes 268 are formed at left and right side parts 265. A pair of left and right air volume control plates 286, 286 for covering parts of the opening holes 268 are provided in the engine hood 6.SELECTED DRAWING: Figure 16
