  • Steering wheel
    Patent number: 9195257
    Abstract: There is provided a steering wheel that can reduce the load applied to an elastic body included in a dynamic damper to lengthen the life of the dynamic damper, and that allows the frequency of the dynamic damper to be adjusted easily. An insulator 14 includes a first flange portion 14a provided between a stopper 13 and an elastic body 15, and a second flange portion 14b provided between a coil spring 17 and the elastic body 15. The elastic body 15 includes a first diameter-increased portion 15a increased in diameter to be contactable with the first flange portion 14a, and a second diameter-increased portion 15b increased in diameter to be contactable with the second flange portion 14b. A contact surface of the first flange portion 14a with the first diameter-increased portion 15a has a plurality of linear projections 14c arranged in a substantially radial fashion.
