To provide a fan structure of a vehicle improved so that vibration and noise emission of a fan are lessened as much as possible without any additional measure such as provision of a separate weight, increase in the hub wall thickness, etc.

The fan structure for vehicle includes a fan equipped with a plurality of blades, wherein the total of X-axis components of all vectors and the total of their Y-axis components are both zero when the blades are represented by vectors of the same size, where the origin of the X-Y cartesian coordinate system is used as base point, and even though the blades are arranged with different angles from one another, the angles of arrangement of the blades relative to one another are such that the rotational center of the fan is identical to the center of gravity.
