PURPOSE: A bush for mounting a steering gear box of a vehicle is provided to prevent vibration, kick-back and shaking of a steering wheel by flowing oil into upper/lower liquid chambers through an orifice. CONSTITUTION: A buffer lever(68) is molded to adhere a bush(60) to upper/lower protrusions(64,66) on the outer circumference of an inner pipe(62). Then, an outer pipe(70) is inserted outside both sides of the buffer lever. An orifice(76) penetrates both sides of the buffer lever, and upper/lower liquid chambers(72,74) are formed on each upper/lower space between the buffer lever and the outer pipe. The bush is combined with a fixed portion(58) on the outer circumference of a steering gear box.
