By arranging in the hose space formed by the bent portion and the stay, even if relative vibration occurs in the internal combustion engine, the radiator, and the cooling water distribution hose, the cooling water distribution hose is reliably protected, and the radiator is also provided. It is an object of the present invention to realize a radiator device in which there is no risk of enlarging the surroundings and the risk of cooling performance deterioration.

[Means for solving problems]

This invention for achieving this object is a radiator that includes a shroud body that includes a shroud portion that forms a space circulation space and a plurality of shroud stay portions that are connected to the shroud portion and that are oriented toward the center of the shroud portion. In the radiator device in which the cooling fan mounted on the internal combustion engine side is installed in the air circulation space, a cooling water circulation hose through which cooling water of the internal combustion engine circulates is connected to the radiator around the shroud portion, The radiator hose connection part to which the cooling water flow hose is connected and the shroud stay part are provided to face each other, and the shroud stay part rises at both ends so as to spread to the internal combustion engine side.

And

[Operation] According to the configuration of the present invention, when the cooling water distribution hose vibrates, the cooling water distribution hose is arranged along the shroud stay portion in the hose space formed by the rising side portion and the stay curved portion. Therefore, even if relative vibration occurs in the internal combustion engine, the radiator, and the cooling water distribution hose, the cooling water distribution hose does not come into contact with the inner edge of the sharp shroud, and the cooling water distribution hose enters the air passing through the radiator. Since it does not come into direct contact with the contained sand etc., it can reliably protect the cooling water distribution hose and prevent damage to the cooling water distribution hose, and also increase the length of the cooling water distribution hose. There is no need to increase the size of the radiator and the cooling water flow hose does not create ventilation resistance, so there is no risk of lowering the cooling performance. .
