The bush assembly for vibration control herein disclosed includes an inner cylinder, an annular stop member encircling the middle portion of the inner cylinder and an outer cylinder which is smaller in length than the inner cylinder. The outer cylinder coaxially encircles the inner cylinder and is radially spaced apart therefrom to define a cylindrical clearance space encircling the inner cyclinder. A generally cylindrical impact absorbing member of vulcanized rubber is secured in the cylindrical space by injection molding and a pair of washers are secured to the outer ends of the inner cylinder. The impact absorbing member has a thin portion encircling the stop member, thick portions on both sides thereof and a wide portion at the end of one of the thick portions, while the outer cylinder has large portions encircling the thick portions, a small portion encircling the thin portion and defining a certain clearance therebetween and a flange at the end of one of the large portions in the direction the wide portion is provided. Also disclosed is a method of making the bush assembly. |
