To increase the force to draw the armature of an electromagnetic valve gear for driving a valve for opening or closing a high-pressure liquid passage and to alleviate valve bouncing, the surface of the core with a coil embedded therein is shaped flat and the surface of the armature facing to the surface of the core is shaped convexly spherical, or the surface of the core is shaped convexly spherical and the surface of the armature is concavely spherical such that the curvature radius of the concavely spherical surface is larger than that of the convexly spherical surface, or the armature is composed by piling thin plates of different diameters such that the surface of the armature facing to the surface of the core forms an approximate convexly spherical surface, so that the gap between the surfaces of core and armature is smaller in the central part compared to that in the peripheral part of the surfaces. By this, the interference of the surfaces is prevented with smaller initial gap in the central portion of the faces even when the armature is installed aslant caused by insufficient accuracy of the component parts, and strong electromagnetic attraction can be secured because the smaller the gap is, the stronger the electromagnetic attraction is.
