Abstract
Upper and lower support members, supporting a valve, are lowered toward a valve guide with at least the lower support member vibrated by a vibrating device. When a lower-end chamfered surface of the valve has failed to be brought into contact with the opening edge of the guide through the lowering, not only the upper support member is caused to gradually move away from an umbrella section of the valve but also the position of supporting, by the lower support member, of a shaft section of the valve is displaced downward after the lower end of the shaft section of the valve contacts the upper end surface of the guide, so that vibrating movement of the lower end of the shaft section is reduced to allow the chamfered surface to contact the opening edge. Then, the valve is inserted into the guide by a pressing member.
