停止装置。[Scope of Claim for Utility Model Registration] In a valve stop device for an internal combustion engine having two intake valves per cylinder, the locker arm of the intake valve on the valve stop side is supported by a locker shaft on a cam side locker arm and a valve side locker arm, which are swingably supported on a locker shaft. On the opposite side of the cam-side rocker arm, extend the lock piece so that it overlaps the lower side of the valve-side rocker arm, and attach the lock piece of the cam-side rocker arm to both ends located in the middle of the valve-side rocker arm. engagement,
An operating arm formed with a removable engaging claw is swingably supported, a compression coil spring is installed inside an operating section extending above the operating arm, and a wedge-shaped spring is installed above the operating section of the operating arm. An operating rod of a valve stop device having an engagement surface is arranged to be movable up and down, and when the engine is running at low to medium speeds, the actuating rod of the valve stop device is lowered to open the engagement claw of the operating arm, and the cam side rocker arm is opened. A valve stop device for an internal combustion engine, characterized in that the valve stopper arm is configured to be separated from the locker arm on the valve side.
