装置。[Scope of Utility Model Registration Claim] An intake and exhaust valve that opens and closes an intake and exhaust port opening into a combustion chamber, a cam that rotates in synchronization with an internal combustion engine, and a rocker shaft that supports the cam and controls the operation of the cam to the intake and exhaust valve. It has a rocker arm that abuts and transmits the transmission, and a spring that always biases the intake and exhaust valve in the closing direction, and the rocker arm has a point of action on the intake and exhaust valve in the direction of the axis of the rocker shaft from the axis of the intake and exhaust valve. In a valve rotating device that is biased by a predetermined amount, the contact surface of the rocker arm that contacts the intake and exhaust valves is comprised of a cylindrical surface having a cylindrical side surface shape and the outermost part of a ring having the same outer radius or the same cross-sectional radius as the cylindrical surface. When the lift amount of the intake/exhaust valve is less than a certain value, the cylindrical surface comes into line contact with the intake/exhaust valve, and the intake/exhaust valve A valve rotating device characterized in that when a lift amount exceeds a certain value, the annular surface comes into point contact with the intake/exhaust valve.
