First Claim
1. A blower device for a vehicle, comprising:
- a plurality of blowers having fan shafts arranged in parallel with each other, for blowing air toward a heat exchanger mounted to the vehicle;
a single motor for driving and rotating the blowers, the motor having a motor shaft;
a shroud for holding the blowers and for forming air passages from the heat exchanger to the blowers, wherein the shroud includes a plurality of shroud ring portions each of which has a circular shape to surround an outer peripheral portion of the blower, and a shroud plate portion extending smoothly from a rear side of the heat exchanger to the shroud ring portions; and
a gear portion through which the fan shafts are coupled to the motor shaft,wherein the motor is located downstream from the shroud plate portion to be offset from a center connection line connecting centers of the shroud ring portions.

Abstract
A blower device for a vehicle includes at least two blowers having fan shafts arranged in parallel with each other, a single motor for driving and rotating the blowers, and a shroud for holding the two blowers. The motor includes a motor portion and a motor shaft driven by and extending from the motor portion. The shroud has shroud ring portions each of which has a circular shape to cover an outer peripheral portion of the blower, and a shroud plate portion extending from the shroud ring portions to an outside. Furthermore, the fan shafts of the blowers are coupled to the motor shaft via a gear portion, and the motor portion is attached to the shroud plate portion to be offset from a center connection line connecting the centers of the shroud ring portions.
