To provide an effective technique for providing an effect of suppressing abnormal sound or noise generated between a steering wheel side and a horn switch mechanism side, by a simple structure, in a steering device in which the horn switch mechanism is incorporated in a steering wheel for vehicle steering mounted on a vehicle.

The steering device 100, in which the horn switch mechanism 120 is incorporated in the steering wheel 101 for vehicle steering mounted on the vehicle, has a configuration of a plastic support part 105 having an uneven-shaped upper surface 105a for supporting a contact plate 122 on the horn switch mechanism 120 side.
