機構。 In a forced opening/closing type valve operating mechanism in which a valve is forcibly opened and closed by rotation of a cam, an opening rocker arm and a closing rocker arm that contact the opening cam and the closing cam, respectively, are integrated so that their positions can be adjusted. Each integrated rocker arm is swingably supported by the engine body through a first spherical bearing, and the end of each rocker arm is connected to the valve shaft through second and third spherical bearings having a common rotation center. A forced opening/closing type valve mechanism characterized in that the second and third spherical bearings and the valve shaft end are slidably provided in a direction orthogonal to the valve shaft, while being supported at each end.
