PURPOSE:To keep a clearance between two valves in a zero state, by supporting two rocker arms pivotally on an adjusting arm being rockably installed in an engine, while installing each rush adjuster in this adjusting arm and one side of these rocker arms. CONSTITUTION:An adjusting lever 11 is pivotally supported on an engine by a second rocket shaft 12, while two rocker arms are pivotally supported on a first rocker shaft 10 to be installed in this adjusting lever 11. In one side of these rocker arm 4, there is provided with a plunger 26 to be energized so as to come into contact with a valve V2 by a hydraulic chamber 30 to be interconnected to the outside through a throttle hole 40 and a spring 31, while a rush adjuster 14 on which a plunger 21 hits is installed in a receiving part 13 of the adjusting lever 11. Therefore, zero rush adjustment always takes place to two suction valves or exhaust valves. |
