の問題もあつた。 As shown in FIG. 4, a conventional engine cooling fan structure includes a hub body 11 having a plurality of fan blades 12, 12', . It was simply constructed of a cylindrical ring structure with a constant width that was approximately equal to the width of the root of the fan blade. Due to the front structure in which a recess is formed, the recessed space completely inhibits the ventilation suction effect of the fan, which naturally tends to reduce the cooling efficiency of the radiator. In addition, in order to improve this tendency for cooling efficiency to decline, the product shape as a fan is generally made larger, the number of fan blades is increased, etc. As a result, not only does the product weight increase, but it also becomes more noisy. There were also some problems.
本考案の目的は、上記した問題を極めて効果的

A mounting wall 3 for attaching to a mating member (not shown), which is perpendicular to the axial direction and is provided on the surface side, is located rearward from the substantially central portion in the width direction of the hub body, and is formed into a cylindrical ring. A plurality of fan blades 2 integral with the hub body and radiating outward are formed on the outer peripheral surface of the hub body 1 by injection molding with a resin material or casting molding with an aluminum or aluminum alloy material. 2', . . . to form a fan. Further, notched air supply grooves 4, 4', . . . are provided in the wall portion extending between the respective fan blades 2, 2', . . . on the front side formed by the cylindrical ring of the hub body 1.

しいところである。 It goes without saying that the notched air supply grooves 4, 4', etc. may have a desired shape depending on the size of the product as a fan or the conditions of use, etc., but preferably they are formed on the rear side in the direction of rotation of the fan. It is desirable that the groove edges have a blade wall structure that slightly protrudes inward from the axis to further enhance the ventilation and suction effect.

The fan blades 2, 2', . Since the structure includes the cutout air supply grooves 4, 4', .
In the concave space formed by this, the ventilation suction effect toward the outer fan blades 2, 2', . This suction effect increases the cooling efficiency of the radiator, making it possible to reduce the size of the product as a fan.Furthermore, the number of fan blades can be reduced, reducing noise and making the product even lighter. It is possible.
