Abstract

PURPOSE: To avoid the wrong seating of a valve due to the vibration of a cam base disc and the deflection of a cam shaft, by providing a minute gap between a check ball and a plunger seat and providing double construction in a retainer which supports the check ball.
CONSTITUTION: In a zero lash adjuster 8 for a finger arm type overhead cam 10, a minute gap A is provided between a plunger 2 and a check ball 3 to absorb the vibration of the base disc of the cam 10 and the deflection of a cam shaft. When an engine is started, oil in an oil reservoir E pushes down the first retainer 4 and the check ball 3 by a stroke B against the force of a check ball spring 5 and flows into a high pressure chamber D. This results in eliminating a hitting noise at starting with low temperature, preventing the wrong seating of a valve and reducing the wear of a rocker arm.
