Abstract

PURPOSE: To stably maintain the initial performane of an engine throughout a long period, by providing a steel ball in contact faces between a rocker arm and valve cap.
CONSTITUTION: A steel ball 2 is provided in contact faces between a rocker arm 1 and valve cap 8. This causes wear to be distributed fully on surfaces of the steel ball 2 thus capable of suppressing the degree of change in a valve clearance to a less amount for the total amount of wear. Accordingly, an on-off timing of the valve and valve lift are permitted a less time aging capable of stably maintaining the initial performance of an engine throughout a long period.
