Abstract: A motor includes a rotor having a rotation shaft, a stator arranged oppositely in a circumferential direction of the rotor, and a pair of bearing portions rotatably supporting the rotation shaft, the pair of bearing portions each include a first bearing being rotatable together with the rotation shaft and a second bearing being rotatable together with the first bearing, the first bearing rotates together with the rotation shaft when the first bearing is normal, and the second bearing as well as the first bearing rotates together with the rotation shaft when the first bearing is abnormal.

Abstract: A fan device 1 includes a second housing 12 and a hub 27. The hub 27 includes a hub body part 272 and a hub outer peripheral wall part 271. The hub body part 272 is a surface extending in the radial direction orthogonal to the direction of the axis x, and the hub body part 272 covers the motor 20 from the upper side “a” in the direction of an axis c. The hub outer peripheral wall part 271 extends from the end portion of the hub body part 272 toward 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 part 271 is “a1”, and the outer diameter of the outer peripheral surface of the base outer peripheral wall part 124 is “b1”, 1.05<b1/a1<1.13 is established.
