A bar is formed on a frame mounted on an inner wall of the binoculars, being positioned approximately close to a center of the lens supporting frame. Guide holes are formed in the bar. Each guide hole is respectively positioned at a portion corresponding to an upper and a lower edge portions of the lengthwise-direction driving frame. Guide pins are respectively mounted on a center portion of the upper and the lower edge portions so as to pierce the guide holes, projecting to a side of objective lenses.
