ABSTRACT:
In a ceramic tip comprising a slipper block engaged by a cam arranged for rotation for causing opening and closing movement of an inlet valve on an exhaust valve of an engine, and a cast body block cast integrally with a valve rocker arm body, a round slope is formed at the conjoined boundary area between the slipper block and the cast body block to prevent occurrence of cracks, and retaining channels are formed on the cast body block to prevent escapement of the cast body block from the valve rocker arm body.
