Claim:
A steering wheel having an airbag device of a vehicle, the steering wheel including a metal core fixed to a steering shaft of the vehicle and a horn switch mechanism by which a horn of the vehicle is activated, the airbag device being joined to the metal core, the horn being activated through the horn switch mechanism when the airbag device is depressed, the airbag device including: a pad; a bag holder attached to a backside of the pad; and an airbag received in a space between the pad and the bag holder in a folded state, wherein the horn switch mechanism includes: a support member that is fixed to the metal core and supports the bag holder in such a manner that the bag holder is allowed to selectively proceed toward and retreat from the metal core, wherein the support member has a first end portion that is fixed to the metal core and a second end portion located opposite to the first end portion, and wherein the second end portion is supported by the bag holder and forms a fixed contact of the horn switch mechanism; an insulating portion arranged between the support member and the bag holder to electrically insulate the support member and the bag holder from each other; an urging member urging the bag holder away from the metal core; and a movable contact moving together with the bag holder, wherein, when the bag holder and the movable contact move toward the metal core against the urging force of the urging member, the movable contact contacts the fixed contact to permit conduction in the horn switch mechanism, thereby activating the horn, wherein the insulating portion of the horn switch mechanism is a movable member that is movable together with the bag holder, wherein the urging member is arranged between the metal core of the steering wheel and the movable member and urges the bag holder away from the metal core through the movable member, and wherein the horn switch mechanism further includes a cap fixed to the movable member in such a manner as to cover the support member, and wherein the movable contact is arranged inside the cap.
