Claims

[Scope of utility model registration request]

A cam piece that operates the valves of some cylinders is rotatably attached to the camshaft of an internal combustion engine, and an electromagnetic clutch is provided to mutually engage or disconnect the camshaft and the cam piece, and the electromagnetic clutch is connected to the camshaft. a first clutch plate that is axially movable and a second clutch plate coupled to the cam piece;
A rolling element or a sliding element protruding toward the other clutch plate is attached to one of these clutch plates, and a concave portion is provided in the other clutch plate corresponding to the radial position of the rolling element or sliding element, When the electromagnet is energized, the first clutch plate approaches the second clutch plate, and the rolling element or sliding element contacts the mating clutch plate and rolls or slides, and engages with the recessed portion. The clutch plates are configured to be in close contact with each other in phase to transmit force, and the electromagnet is connected to the second clutch plate.
A magnetic stopper is disposed on the opposite side of the clutch plate from the first clutch plate, and a magnetic stopper is disposed in a portion where a part of the electromagnet is cut out so as to be movable in the axial direction, and the stopper is pressed against the second clutch plate. A spring is provided to separate the stopper from the second clutch plate against the spring when energizing the electric magnet, and when the energization is turned off, the stopper abuts against the second clutch plate and the second clutch plate is moved away from the stopper. A valve actuation stop device for an internal combustion engine configured to engage a locking means of a second clutch to stop the second clutch at a predetermined position.
