Abstract: The interior of the first reservoir is open to the atmospheric air. A first liquid retaining portion and a first air retaining portion are provided in the first reservoir. The interior of the second reservoir is sealed. A second liquid retaining portion and a second air retaining portion are provided in the second reservoir. A communicating portion allows communication between the second air retaining portion and the first liquid retaining portion. The opening of the communicating portion in the first liquid retaining portion is located lower than a minimum water level of the first liquid retaining portion. The opening of the communicating portion in the second air retaining portion is located higher than a maximum water level of the first liquid retaining portion.

Abstract: This cooling fan device for a vehicle comprises: a fan shroud which is shaped as a box accommodating a radiator and/or a condenser, and which has an opening in the front side in the travel direction of the vehicle and a fan coupling surface in the rear side in the travel direction; at least two cooling fans disposed in the fan coupling surface, the cooling fans having center axes vertically separated from each other by a predetermined distance; and a shield rib extending downward from the top of the fan coupling surface, protruding toward the radiator and/or the condenser, and having a top end and a bottom end, the shield rib being provided to the fan coupling surface between the adjacent cooling fans. The top end and/or the bottom end of the shield rib have a cutout section allowing air to pass between the adjacent cooling fans.
