Abstract: PURPOSE: A valve open-close mechanism by using an electromagnetic actuator is provided to lighten the weight of the valve-open-close mechanism by forming a stem from a lighter material than conventional. CONSTITUTION: A pair of electromagnets(6,7) formed of a stator(5) and a coil(18) is apposed to each other with a gas(10) therebetween. An armature(3) is disposed in the gap to be reciprocal between one electromagnet and the other electromagnet by the electromagnets. A first stem(15) for transmitting the movement of the armature from one electromagnet toward the other electromagnet to a valve(9) of an internal combustion engine is inserted in a guide hole(22) formed in the stator of one electromagnet. The first stem is formed of a lighter material than the armature to lighten the weight of the electromagnetic actuator and the valve-open-close mechanism of the internal combustion engine.
