摘要： A ceramic valve supporting structure comprising in use for internal combustion engine; a ceramic valve (1) having an integral stem (1b), the upper portion of which is provided with a circular groove (2); a cotter (3) the outer surface of which is taperd, and formed by butting a pair of semi-cylindrical pieces, and having a lock projection (3a) placed into the groove when secured concentrically to the outer surface of the stem, a cylindrical retainer (4) concentrically secured to the outer surface of the cotter (3) so as to support the valve (1) through the cotter (3); the retainer (4) being provided with the inner surface tapered in a direction so as to make the cotter (3) tightly engage with the outer surface of the stem (1b) by means of wedge effect against the tapered cotter (3) due to the urging force of a coil spring member (6) axially exerted to the retainer (4); and a stress relief means (50) provided so as to avoid the predetermined portion of the cotter (3) from locally engaging against the outer surface of the stem. As a way of example, the stress relief means (50) is made from heat-resistant elastic layer which positions between the inner surface of the cotter and the outer surface of the stem in order to make the cotter engage with the stem (1b) therethrough.
