ーシヤフト支持構造。 The rocker arm, which opens and closes the valve, is swingably supported by one end that contacts the rotating cam and moves up and down, and the other end that goes up and down in the opposite direction. In the rocker shaft, the rocker shaft and the supporting portion are configured to suppress propagation of vibrations generated by collision between one side end of the rocker arm and the cam when the cam raises the side end of the rocker arm to the cylinder head. A rocker shaft support structure characterized in that a vibration propagation suppressing member is interposed between the rocker shaft support structures.
