The utility model relates to a valve rocker mechanism of gasoline engine which is composed of a regulating screw 1, a regulating screw fixed nut 2, a valve rocker 3, a guide block 4, a clearance regulating nut 5, a locking nut 6 and a feather key 7. The lower part pf the valve rocker is groove shape. The valve rocker mechanism of gasoline engine is characterized in that a rectangular guide block 4 is fixedly sleeved on the middle section of the regulating screw 1. The cambered surface of the bottom of the guide block 4 is inosculated with the cambered surface of the inner wall of the concave groove of the valve rocker 3 and the guide block 4 is fallen in the concave groove of the valve rocker 3. A valve clearance regulating nut 5 is equipped above the guide block 4. The valve rocker mechanism of gasoline engine can effectively guarantee that the valve rocker does the directional swinging according to the motion law (make the air inlet valve and the air exhaust valve be opened and closed on time according to the distributing phase requirement) in the situation that the valve push rod support is cancelled and the noise caused by the valve push rod and the support rubbing is eliminated. The valve rocker mechanism of gasoline engine is provided with well running and reliable operation.
