Claims

[Scope of utility model registration request]

A swinging arm shaft extending in the direction of the cylinder row is mounted on the top surface of a plurality of bearing bodies provided at cylinder intervals on the top surface of the cylinder head, and the swinging arm shaft is mounted in a direction perpendicular to the swinging arm shaft. While being fastened to each of the bearing bodies with a penetrating fastening bolt, two swings for each of the two intake valves or exhaust valves provided in one cylinder are attached to the portion between the bearing bodies of this swing arm shaft. In a valve train in which arms are rotatably fitted, the two swinging arms for the one cylinder are configured to be slidable in the axial direction of the swinging arm shaft into which the two swinging arms are fitted,
Further, a spring means is provided between the two swing arms for urging the two swing arms to press against a bearing body on the outside thereof, and a spring means is provided between the two swing arms for pressing the bearing body on the outside thereof, and a spring means is provided between the two swing arms, and A valve operating device for an internal combustion engine, characterized in that the length in the axial direction of the swinging arm shaft of the flat surface provided in the portion through which the bolt passes is configured to be wider than the width dimension of the bearing body.
