- the regulating member 50 regulates the movement of the cooling fan unit 15 in the direction approaching the radiator core 16 when the cooling fan unit 15 is pulled up. Therefore, when the cooling fan unit 15 is removed from the work vehicle 100, the restriction member 50 can prevent the cooling fan unit 15 from swinging toward the radiator core 16.

- the vertical distance between the first right restricting portion 52 and the fan bracket 32 is smaller than the vertical dimension of the fan bracket 32. Therefore, when the cooling fan unit 15 is pulled up, the fan bracket 32 swings between the first left restricting portion 51 and the fan bracket 32 or between the first right restricting portion 52 and the fan bracket 32. Can be suppressed.
- the distance between the first left restricting portion 51 and the first surface 46 is smaller than the distance between the cooling fan 31 and the radiator core 16.

Therefore, the amount of movement of the cooling fan unit 15 until the first surface 46 comes into contact with the first left restricting portion 51 or the first right restricting portion 52 is suppressed. Thereby, interference with the radiator core 16 can be suppressed.
- the second left restricting portion 53 and the second right restricting portion 54 are disposed in the same manner as the first left restricting portion 51 and the first right restricting portion 52, respectively. Therefore, the second left restricting portion 53 and the second right restricting portion 54 can achieve the same effects as the first left restricting portion 51 and the first right restricting portion 52 described above.

Can be prevented from swinging through.
- a fan motor 35 that drives the cooling fan 31 is attached to the fan bracket 32. Therefore, since the heavy fan motor 35 is attached to the fan bracket 32, the cooling fan unit 15 is likely to swing when the cooling fan unit 15 is removed.
