Abstract
A horn switch mechanism 15 has a securing pin 31 serving as a support member, a movable member 32 serving as an insulating portion, a compression coil spring 35 serving as an urging member, and a contact terminal 34 serving as a movable contact. The securing pin 31 is fixed to a metal core 12 of a steering wheel body 11 and supports a bag holder 21 in such a manner that the bag holder 21 selectively proceeds toward and retreats from the metal core 12. The movable member 32 is arranged between the securing pin 31 and the bag holder 21 and electrically insulates the securing pin 31 and the bag holder 21 from each other. The coil spring 35 urges the bag holder 21 away from the metal core 12. The contact terminal 34 moves together with the bag holder 21. When the bag holder 21 moves toward the metal core 12 against the urging force of the compression coil spring 35, the contact terminal 34 contacts the securing pin 31 and permits conduction between the contact terminal 34 and the securing pin 31. This activates a horn device 40 of the vehicle.
