Claims (1)
、バルブを閉弁方向に付勢するスプリングの一端
が接するリテーナと、このリテーナとバルブステ
ムとの間に配置されバルブステムに対し軸方向移
動が規制されるコレツトとが装着された内燃機関
のセラミツク製吸排気バルブにおいて、前記バル
ブステム外周の少なくとも前記コレツトが装着さ
れる部位付近に金属層を設けたことを特徴とする
内燃機関の吸排気バルブ。 A retainer has one end of a spring that biases the valve in the closing direction in contact with the stem end of the ceramic intake and exhaust valve, and is placed between the retainer and the valve stem to restrict axial movement relative to the valve stem. What is claimed is: 1. A ceramic intake and exhaust valve for an internal combustion engine to which a collector is attached, characterized in that a metal layer is provided on the outer periphery of the valve stem at least near a portion where the collector is attached.
