Next, the operation will be described.

When the fan supporting member 11 is assembled, the structure shown in FIG.
First, the pin 35 of the lower mounting portion 27 of the fan support member 11 is inserted into the mounting recess 65 of the leg portion 61 of the shroud 41 as shown in FIG. Since the insertion portion 63 is provided with a notch 67 that opens to the opposite side of the assembling recess 65, when the pin 35 is inserted into the assembling recess 65 from diagonally above, the notch 67 is inserted into the pin 3.
5 is in a protruding state. From this state, the fan support member 11 is raised to the shroud 41 side, and the protrusion 57 is inserted into the hole 33 of the upper assembly portion 25 as shown in FIG. Thereby, the upper surface 37a of the contact portion 37 of the fan support member 11 is
The vertically extending portion 54 of the fan support member 11 abuts against and is supported by the fan support member 11, and the fan support member 11 and the shroud 41 are integrated. Then, the insertion portion 63 of the shroud 41 is inserted into the through hole 9 of the bracket 7, and the bolt 70 is inserted into the hole portion 55 of the fixing portion 49 of the shroud 41 as shown in FIG.
0 is fastened and fixed in the fastening hole 5 of the radiator 1. Bolt 7
When 0 is fastened and fixed, the surface 53 of the fixed portion 49 and the surface 31 of the upper assembly portion 25 come into contact with each other, and the upper fixing bracket 47 comes into contact with the abutting portion 37. The assembling portion 25 is supported.

As described above, in this embodiment, the lower assembly part 2 is used.
Since the fixing position of 7 is restricted by the pin 35 inserted in the hole 65, the fastening position by the bolt 70 is only required to be the upper mounting part 49, and the fan supporting member 11 is raised to be integrated with the shroud 41. Therefore, the workability of assembling the fan support member 11 is improved, and the cost can be reduced.

Further, an assembling recess 65 into which the pin 35 is inserted
Since it is provided in the insertion portion 63 of the shroud 41, space saving can be achieved as compared with the case where the assembly recessed portion 65 is provided in another portion.

By inserting the projection 57 of the fixing portion 49 of the shroud 41 into the hole 33 of the lower assembly portion 27,
The fan support member 11 can be easily positioned with respect to the shroud 41.

Further, since the upper arm portion 21 is provided with the contact portion 37 for contacting the upper fixing bracket 47, the fan support member 11 is also supported by the contact portion 37 when the shroud 41 is fastened and fixed to the mounted portion. It will be in the state of being.
This improves the assembling strength of the fan support member 11.

[0026]

As is apparent from the above, according to the invention of claim 1, the fastening and fixing portion is only required between the fixing portion and the attached portion of the shroud, and the shroud is provided in the hole portion of the upper assembling portion. Since the positioning can be easily performed by inserting the protrusion of the fixing portion, the workability of assembling the fan supporting member is improved, and the cost can be reduced.

Since the mounting recess is provided in the leg portion, it is possible to save space.

According to the second aspect of the present invention, the pin is inserted into the assembling recess from diagonally above or from the lateral direction, and the fan support member is raised toward the shroud side with the pin as the center so that the projection is inserted into the hole. Therefore, the workability of assembling the fan support member is further improved. Moreover, since the fan support member is supported by the contact portion, the assembling strength of the fan support member is improved.
