弁装置。 A plurality of cam followers for opening and closing the intake valve or the exhaust valve are arranged adjacent to each other so as to be able to operate in different manners depending on the rotation of the camshaft. A switching pin that is slidably fitted to the cam follower of the cam follower and also fitable to the other cam follower, a regulation pin that abuts coaxially with the switching pin and is slidably fitted to the other cam follower, and a regulation pin. In a valve train for an internal combustion engine, a coupling switching mechanism is provided which has a return spring interposed between the other cam follower and a regulating pin in order to urge the other cam follower toward one cam follower. A guide hole with an open bottom is drilled on one cam follower side for movable engagement, and the regulation pin is formed into a cylindrical shape with a bottom that accommodates a return spring inside.The regulation pin is attached to the inner surface of the guide hole. A valve operating device for an internal combustion engine, characterized in that a retaining ring is fitted to prevent the valve from slipping out of the guide hole.
