とを特徴とする動弁装置。 A valve operating device that transmits the elastic force of the valve spring to the intake and exhaust valves by locking a valve spring retainer to the end of the valve shaft of a ceramic intake/exhaust valve via a retainer, the valve spring retainer being formed at the end of the valve shaft. In the valve operating device, the valve spring retainer is brought into pressure contact with a tapered outer circumferential surface formed on the outer surface of the kotsuta by engaging a protrusion having an arcuate cross section formed on the inner surface of the kotsuta with an annular groove having an arcuate cross section. A valve operating device characterized in that a material layer having a lower hardness than the other material is formed on the contact surface of at least one of the annular groove and the protrusion.
