排気弁の作動停止機構。A swing arm type rocker arm has one end rotatably supported by the rocker shaft and the other end abuts against the valve stem of the intake and exhaust valve, and the rocker arm is brought into contact with the middle part of the rocker arm and is supported by the rocker shaft as a fulcrum. In a valve train for an internal combustion engine that has a cam that swings, the rocker arm has two separate arms, a first arm that is pivotally supported by the camshaft, and a second arm that is abutted against the valve stem. The first and second arms are connected by a common fixed shaft so as to be relatively rotatable about the fixed shaft, so that both arms can be fixed in the operating position where both arms extend integrally. It can be selectively set to an inoperative position bent around the axis.
Further, between the first and second arms, there is provided a locking means for integrally locking both arms in the operating position by preventing relative rotation of the two arms, and a locking means for releasing the locking means at a predetermined time. A mechanism for stopping operation of an intake and exhaust valve in an internal combustion engine, characterized in that a return means is provided for constantly urging the arm toward the operating position and for returning both arms to the operating position when the lock is released.
