PROBLEM TO BE SOLVED: To suppress an unusual sound from a horn switch device supporting an air bag device and improve the operability of the horn switch. SOLUTION: An air bag device 21 is supported by a horn switch device 22 so as to be advanced and retreated with respect to a steering wheel body 2. The horn switch device 22 guides a shaft part 38b of a torque bolt 38 inserted into a through hole 37a of a secondary resin insulator 37 so as to be advanced and retreated. A tongue-shaped urging piece 37g which is slightly inclined in a direction of the central axis of the through hole 37a is projected from the four places of a tip 37f of a cylindrical part 37c of the second insulator 37. The tip of the urging pieced 37g slidably contacts with the shaft part 38b of the torque bolt 38. The urging piece 37g flexes and absorbs vibration, thus suppressing an unusual sound. |
