  2. Description of the Related Art Conventionally, a lower mounting portion of a radiator and a radiator fan has an insertion structure so that the radiator fan can be easily attached and detached from above in consideration of the repairability of the radiator and the radiator and the radiator. However, when the conventional insertion structure is adopted for the radiator and radiator fan lower mounting part, the insertion part is not protected by a rubber bush, etc., and dust and muddy water can easily enter the insertion part when traveling on rough roads. There is a risk that the mounting portion will wear and play, causing abnormal noise. Therefore, it is conceivable to use bolt fastening for the lower mounting part as a countermeasure against wear of the lower mounting part of the radiator and the radiator fan. In this case, bolts, nuts, collars, etc. are required, which is costly and assembled. Sex is reduced. Furthermore, when bolt fastening is used, it is necessary to tighten the bolt when attaching or detaching the radiator fan. However, when the cooling device is attached to the vehicle, it is necessary to tighten the lower bolt to limit space. Since it is difficult to attach and detach only the radio fan, the repairability is deteriorated.

In addition, the conventional cooling device mounting structure described above has many assembly procedures until the radiator and the radiator fan are mounted on the radiator support, and it takes time for the assembly work. Therefore, it is desirable to improve the assembly performance. As an assembly procedure in the conventional cooling device mounting structure, for example, the following steps are included.
(1) A step of assembling the radiator and the radiator fan by connecting the radiator and the lower mounting portion of the radiator fan by an insertion structure.
(2) A step of assembling the cooling device by fastening the assembled radiator and the upper mounting portion of the radiator fan with bolts.
(3) A step of fitting the upper side rubber bush into a mounting hole formed in the radiator support upper and attaching it.
(4) A step of fitting the lower rubber bush into the mounting hole formed in the radiant sapphire.
(5) A step of inserting a protrusion provided on the lower part of the radiator into the lower rubber bush and attaching the lower part of the cooling device to the radiator support.
(6) A step of inserting the protrusion provided on the upper portion of the radiator into the upper rubber bush and attaching the upper portion of the cooling device to the radiator support upper.

  One of the objects of the present invention is a cooling device mounting structure that can improve the wear resistance of the radiator and the lower mounting portion of the radiator fan while ensuring the repairability of the radiator fan while having a simple configuration and excellent assembly. Is to provide.

The mounting structure of the cooling device according to one aspect of the present invention is as follows.
A cooling device mounting structure comprising a radiator mounted on a radiator support of a vehicle and a radiator fan disposed on the radiator,
The radiator support has a radiator support lower to which a lower portion of the radiator is attached,
The radiator support lower has an attachment hole formed therein, and has a lower elastic bush fitted into the attachment hole.
A first protrusion and a second protrusion, which are provided at a lower portion of the radiator and a lower portion of the radiator fan, and are combined with each other in a state where the radiator and the radiator fan are assembled;
The first protrusion and the second protrusion are combined with each other and inserted into the lower elastic bush.

  The mounting structure of the cooling device is configured such that a first protrusion and a second protrusion that are combined and integrated with each other are provided at lower portions of the radiator and the radiator fan, and both protrusions are integrally inserted into the lower elastic bush. The first protrusion and the second protrusion provided at the lower part of each of the radiator and the radiator fan are aligned with each other and inserted into the lower elastic bush, so that the lower part of the radiator and the radiator fan can be connected to each other and attached to the radiator support. Therefore, it is excellent in assemblability with a simple configuration. In other words, one lower elastic bush can be shared for both the radiator and radiator fan lower mounting part, and the radiator support and radiator lower mounting part, and no elastic bushing is used for each mounting part. Therefore, simplification of the configuration and cost reduction can be achieved. Since the lower mounting portion of the radiator and the radiator fan has an insertion structure in which the first protrusion and the second protrusion are inserted into the lower elastic bush, it is easy to attach and detach only the radiator fan to the vehicle. Easy to secure. In addition, since the first protrusion and the second protrusion are inserted into the lower elastic bush, and the first protrusion and the second protrusion of the radiator and the fan are covered with the lower elastic bush, it is difficult for foreign matters such as sand to enter, and the lower mounting portion Wear can be suppressed, and wear resistance can be improved. In addition, since the second projection of the radio fan is also inserted and fixed in the lower elastic bush, vibration is easily suppressed.
