Since the clearance between the inner diameters of the valve V and the valve guide G is quite tight, it is quite difficult to insert the valve accurately without damaging the mouth of the valve guide. However, in the past, the relationship between the valve and the valve guide was as described above, so if a valve insertion device or jig was to be used, the device or jig would be extremely complex in structure, which would pose a cost problem. Become. For this reason, the work had to be carried out manually by workers without using any aspiration equipment or jigs. However, the work of inserting the valves was a very delicate work, and the valves had to be inserted one by one, which was not only hard labor but also poor work efficiency.
