Zusammenfassung:	The purpose of the invention is to prevent a sticking of lubricant to a ball screw shaft and a scattering to the circumstance in an electromotive toggle mold clamping device. This invention relates to the electric motor driven toggle mold clamping device wherein a ball nut member is screwed together to the ball screw shaft which rotates by an electric motor to advance and retreat freely and a cross head is fixed to the ball nut member, a cylindrical or polygonal cylindrical member which has a cylindrical body shape or square cylindrical body shape with a length and a size of placing the ball screw shaft with a required gap while retreating the cross head, is attached to the front ends of the cross head concentrically with the ball screw shaft. The ball screw shaft protruding from the cross head is placed in the cylindrical or polygonal cylindrical member having a required gap.
