Claims

[Claims for Utility Model Registration] 1. A cam that rotates in relation to the rotation of an internal combustion engine, a rocker arm that swings due to the rotation of the cam,
A valve operating system for an internal combustion engine including an intake valve that is opened and closed by swinging of the rocker arm, the rocker arm including a rocker arm body and a rocker arm movably attached to the rocker arm body. It is characterized by comprising a roller against which the cam comes into contact, and a roller actuation mechanism for moving the roller, the roller actuation mechanism including an electromagnetic solenoid actuated in relation to the rotational speed of the internal combustion engine. Valve gear for internal combustion engines. 2. The roller actuation mechanism further includes a roller support member on which the roller is rotatably mounted and to which the output end of the electromagnetic solenoid is connected, and when the electromagnetic solenoid is actuated, the roller A valve train for an internal combustion engine according to claim 1, wherein the roller is moved via a support member. 3. The valve operating system for an internal combustion engine according to claim 1 or 2, wherein the electromagnetic solenoid is activated when the rotational speed of the internal combustion engine is below a predetermined rotational speed.
