る虞があつた。 The fan shroud of an engine cooling fan is often attached to the internal combustion engine side in order to improve the cooling performance of the radiator by minimizing the clearance with the tip of the fan. 1st
The figure is an external view showing this fan shroud support structure. 1 is a cooling fan, 2 is a fan shroud, and 3 is a bracket for attaching the fan shroud 2 to an engine (not shown), which are provided at three locations at approximately equal intervals. FIG. 2 is a sectional view showing details of the area around the bracket 3. A nut 4 is welded to the inside of the fan shroud 2, and a bolt 6 is inserted through a spring washer 5 into a through hole drilled in the bracket 3 and the fan shroud 2, and is screwed onto the nut 4, thereby attaching the bracket 3 to the fan shroud 2. Fixed to . In such a fan shroud support structure in which the fan shroud 2 is attached to the engine side, engine vibrations are transmitted to the fan shroud 2 via the bracket 3. Since the nut 4 for fixing the bracket 3 to the fan shroud 2 is welded to the fan shroud 2 as described above, the strength of this welded part of the fan shroud 2 is reduced, and there is a risk of cracking due to engine vibration. It was hot.

FIG. 3 is an external view of a fan shroud and a cooling fan having a fan shroud support structure according to an embodiment of the present invention. FIG. 4 is a partial side view showing the details. As shown in FIG. 5, 4' is a thick plate member which is curved in substantially the same shape as the fan shroud 2' and has screw holes 4'a, 4'b, and 4'c extending therethrough. fanciloud 2'
The screw holes 4'a, 4'b, 4'c of this member 4' are arranged at approximately equal intervals to the screw holes 4'a, 4'b, 4'c.
Larger holes 2'a, 2'b, 2'c are drilled, and bolts 6', 6'' into which spring washers 5', 5'' are inserted are inserted into through holes 2'a, 2'c. and then screwed into the screw holes 4'a and 4'c of the member 4, respectively.
By tightening, the member 4' is fixed inside the fan shroud 2'. The bracket 3' has a bolt 6 into which the spring washer 5 is inserted, and is screwed into the screw hole 4'b of the member 4' through the through hole 3'a of the bracket 3' and the through hole 2'b of the fan shroud 2'. , by tightening the fan shroud 2'
