SUMMARY OF THE INVENTION In order to solve the above-mentioned technical problem, the present invention provides a structure in which a radiator is mounted on a radiator support provided in an engine room of a vehicle, wherein one edge of the radiator has one edge of the radiator support. A stud bolt is attached to the mounting position of the radiator support, which is mounted on the mounting target side and mounts the other edge of the radiator, facing the same edge, and the other edge is mounted in a crown-like shape. A clip body having a locking leg elastically locked to an edge, and integrally formed with a vibration-proof material that is in close contact with a mounting stay of the radiator;
On one of the locking legs of the clip body, a locking holding portion having a plurality of locking claws which are fitted to the stud bolts and which are locked to the screw portions of the stud bolts so as not to come off is integrally formed. The fixing structure of the radiator is characterized in that the fixing clip is provided and connected to the mounting target side of the radiator support via the fixing clip.

[0006]

When the fixing clip is previously attached to the upper tank constituting the upper edge of the radiator core or to the support receiving portions of the left and right radiator vertical frames of the core 1C, for example, the radiator is attached to the radiator support. Conventionally, the locking and holding portion formed integrally with the fixing clip is fitted and locked to the upper support or the stud bolt mounted on the vertical support to which the radiator support is mounted, and is connected and held. As described above, the number of operations by the fastening members and the like can be omitted, and the workability of assembling the radiator can be extremely simplified. In addition, since the fixing clip is formed integrally with the clip main body having the locking leg to the radiator and the locking and holding part to the stud bolt, the number of parts to be attached to the radiator support and the number of steps can be reduced, and the radiator support can be reduced. Strength can be maintained.
