An air outlet (A) and a vehicle comprising same. The air outlet (A) comprises a motor (60), the motor (60) comprising an output shaft (601); a one-way bearing (12), the one-way bearing (12) comprising an inner ring (121) and an outer ring (125), and the output shaft (601) being connected to the inner ring (121) or the outer ring (125); and an inner air guide device and an outer air guide device, the inner air guide device being connected to the inner ring (121) and the outer air guide device being connected to the outer ring (125), or the inner air guide device being connected to the outer ring (125) and the outer air guide device being connected to the inner ring (121). By virtue of rotation of the output shaft (601) in the forward and reverse directions, the motor (60) simultaneously drives both the inner air guide device and the outer air guide device by means of a one-way bearing (12), and drives both the inner air guide device or the outer air guide device separately by means of the one-way bearing (12). According to the air outlet (A), a single motor (60) is used to realize the linkage rotation of the inner and outer air guide devices and the independent rotation of the inner and outer air guide devices when the output shaft (601) rotates forward and backward; moreover, the angle relationship between the inner and outer air guide devices can be adjusted, and the inner and outer air guide devices can be positioned at any position.
