Claims

[Claims for Utility Model Registration] 1. A first cooling fan and a second cooling fan are arranged side by side and rotatably supported behind an oblong radiator for a vehicle, and only the first fan is driven by one drive. The first fan and the second fan are each provided with annular coupling means that engage with each other on their outer peripheries, so that the second fan is rotationally driven as the first fan is rotationally driven. In the cooling device for a radiator, the first fan is disposed so as to be movable back and forth in the axial direction between a first position and a second position, and the first fan is disposed in the coupling means so as to be movable back and forth between a first position and a second position. A cooling device for a radiator, characterized in that a radiator cooling device is provided with retaining surfaces that are disengaged when the box moves to the second position and engage with each other when the box moves to the first forward position. 2. A request for registration of a utility model in which the engaging surface of the coupling means of the first fan is a conical shape that widens toward the rear, and the retaining surface of the coupling means of the second fan is a conical shape that widens toward the front. A cooling device for a radiator according to item 1. 3. The cooling device for a radiator according to claim 1, wherein the retaining surfaces are toothed surfaces that engage with each other.
