PURPOSE: A parallelism adjusting device of a movable clamping mechanism for an electric injection molding machine is provided to improve the accuracy and quality reliability of molded products because strength in a forward and backward movement direction of a movable clamping mechanism is obtained and a vertical distance and a longitudinal distance thereof can be controlled in a narrow space. CONSTITUTION: A parallelism adjusting device of a movable clamping mechanism for an electric injection molding machine comprises first wedges(28a,28b), spiral rods(36), and position adjusting and joining pieces(38). Each wedge comprises an inclined part(30) and a side part(34). The inclined parts are inserted between a base plate(22) and a support plate(26). The side parts are formed in one side of the inclined parts. The first wedges are arranged in the spiral rods to place the inclined planes of either the base plate or the support plate on the inclined planes of the inclined parts. The spiral rods are coupled to the base plate while penetrating the side parts. The position adjusting and joining pieces are coupled to the spiral rods in both sides of the side parts.
