  • Patent number: 8733203
    Abstract: A steering wheel in which a load exerted on an elastic member constituting a dynamic damper can be reduced, the life of the dynamic damper can be extended, and the assembly operation is readily performed. The steering wheel has a first horn plate (11), a second horn plate (21), guide pins (12), stoppers (13), bushes (14), elastic members (15), and coil springs (16); the bushes (14) are divided into first bushes (141) which have first flanges (14a), openings (14b), columnar parts (14c); and recessed parts (14d), and second bushes (142) which have second flanges (14e), openings (140, and casings (14h); and the columnar parts (14c) are configured so as to be in contact with the second flanges (14e).

  • Patent number: 8286766
    Abstract: A slider 24 is supported on a holder 19 of a steering wheel 11 via a coil spring 25 so as to be movable in a direction of an axis while an air bag module 20 is supported on a slider 24 via a damper spring 26 so as to be movable in a direction perpendicular to the axis. Since the coil spring 25 does not affect vibration of the air bag module 20 in the direction perpendicular to the axis, it is possible to set a spring constant of the coil spring 25 at a value appropriate for the operation of a horn switch 37, and to set a spring constant of the damper spring 26 at a value appropriate for the operation of the dynamic damper. As a result, it is possible to effectively reduce the vibration of the steering wheel 11 in the direction perpendicular to the axis with the dynamic damper without affecting the operability of the horn switch 37.
