There is provided a solenoid-type valve actuator for an internal combustion engine, having an inexpensive and single construction which is capable of maintaining stability of operation of a valve and reducing sliding resistance to the valve at the same time, thereby achieving improved response of the valve and reduced power consumption of electromagnets. The solenoid-type valve actuator electromagnetically opens and closes a valve. Two electromagnets are arranged in a manner opposed to each other with a space therebetween. An armature is arranged between the two electromagnets, for reciprocating motion by energization and deenergization of the two electromagnets. Two shafts project from respective opposite sides of the armature and extend through the two electromagnets, respectively, one of the shafts being connected to the valve. Two shaft guides are arranged in at least one of the two electromagnets in a line along the direction of the reciprocating motion of the armature, for guiding a reciprocating motion of at least one of the two shafts performed according to the reciprocating motion of the armature.
