摘要
A vibration reducing device of a steering column is provided to change resonant frequency of the steering column by increasing the weight of the steering column by attaching a metal member to the steering column according to vibration degree of the steering column. A vibration reducing device of a steering column(10) is composed of a first metal member(12) positioned on both upper sides of the steering column; a second metal member(14) arranged at both lower sides of the steering column; a first electromagnet(16) installed in the steering column to attach the first metal member to the steering column; a second electromagnet(18) mounted in the steering column to stick the second metal member to the steering column; and an electromagnet driving unit(30) for generating magnetic force by supplying an electric current to the first electromagnet according to the vibration transmitted to a steering wheel(20) or supplying the electric current to the first and second electromagnets at the same time.
