Claim:
A bonnet structure applicable to a working vehicle including a radiator, a cooling fan and an engine, which are disposed in order from a front to a rear of the vehicle, a shroud that surrounds the cooling fan, an air cleaner that is disposed in front of the shroud, an intake pipe that has a first end connected to the air cleaner and a second end connected to an inlet port of the engine, and a bonnet that is rotatable about a rotary shaft along a vehicle width direction so as to be located at a closed position for covering these members and at an opened position for exposing these members, wherein the shroud includes a shroud main body provided with an opening that surrounds the cooling fan, and a pair of shroud flanges that respectively extend outward in the vehicle width direction from side surfaces of the shroud main body, each of the shroud flanges having an anteroposterior contact surface that is directed to a first direction, which is opposite to the rotary shaft in the vehicle longitudinal direction, wherein the bonnet is provided with a bonnet flange that extends inward from an inner peripheral surface of the bonnet, and a first elastic sealing member that is attached to the bonnet flange, wherein the bonnet flange is provided to the bonnet so as to be positioned farther toward the first direction than the pair of shroud flanges when the bonnet is located at the closed position, wherein the first elastic sealing member is brought from the first direction into contact with the anteroposterior contact surface when the bonnet is rotated about the rotary shaft from the opened position to the closed position, wherein each of the pair of shroud flanges is inclined so as to be positioned farther toward the first direction as it extends downward, and wherein the bonnet flange is inclined correspondingly to the shroud flange.
