Abstract:
1. A steering wheel including a main body assembled on a steering shaft for converting a rotating action into a steering action, and a pad unit provided at almost the center of the main body, the pad unit being assembled to the main body such as to be movable in an axis direction of the steering shaft, and a horn switch being provided between the main body and the pad unit, wherein the steering wheel comprises a first horn plate fixed to the main body, a second horn plate fixed to the pad unit, a guide pin standing on one of the first horn plate and the second horn plate, a stopper provided at a distal end of the guide pin, an insulator inserted slidably along the guide pin, an elastic body fitted on an outer periphery of the insulator, a protector fitted on an outer periphery of the elastic body and provided engageably with the other of the first horn plate and the second horn plate, and a coil spring fitted on the guide pin to bias the insulator toward the stopper, wherein the insulator includes a first flange portion provided between the stopper and the elastic body, and a second flange portion provided between the coil spring and the elastic body, and the elastic body includes a first diameter-increased portion increased in diameter to be contactable with the first flange portion, and a second diameter-increased portion increased in diameter to be contactable with the second flange portion, and wherein a contact surface of the first flange portion with the first diameter-increased portion has a plurality of linear projections arranged in a substantially radial fashion, and wherein an amplitude or frequency produced by vibration of the pad unit is controlled by adjusting any of radial widths of the first flange portion and the first diameter-increased portion, a thickness of the first diameter-increased portion, a number, a length, a height, and a width of the linear projections.
