Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a front end structure of a vehicle, and a radiator support therefor, mounted on the front end of the vehicle.

[0003] 2. Description of the Related Art

[0004] As a front end structure of a vehicle, for example, in the invention according to the Japanese Patent Publication No. 3293546, a reserve tank for a radiator is integrated with a fan shroud and a level gauge, which is provided for checking the quantity of cooling water in the reserve tank, is mounted on the rear side, in the vehicle direction, of the reserve tank.

[0005] The reserve tank has a function to compensate for a variation in the water quantity in the radiator. A radiator support is a structural member to which at least a heat exchanger, such as a radiator, etc., is attached and is called as a “carrier” or a “front end panel” in some documents.

[0006] As a level gauge is mounted on the reserve tank at the rear side of the vehicle, when a worker checks the level of cooling water remaining in the reserve tank by eye, especially during assembling the vehicle, or the like, he must put his head into an engine compartment, as shown in FIG. 4, to check the level of the cooling water.

[0007] Due to such a construction in a vehicle, such as a light automobile which has a short front end, it is likely that a worker will hit his head against an engine hood, a vehicle body, or the like, when checking the level of cooling water in the reserve tank.
