Abstract
A fan deviceincludes a second housingand a hub. The hubincludes a hub body partand a hub outer peripheral wall part. The hub body partis a surface extending in the radial direction orthogonal to the direction of the axis x, and the hub body partcovers the motorfrom the upper side 'a' in the direction of an axis c. The hub outer peripheral wall partextends from the end portion of the hub body parttoward the lower side 'b' from the upper side “a” in the direction of the axis x. Assuming that the outer diameter of the outer peripheral surface of the hub outer peripheral wall partis “a1”, and the outer diameter of the outer peripheral surface of the base outer peripheral wall partis “b1”, 1.05<b1/a1<1.13 is established.
