ABSTRACT:
A binocular telescope provided with a pair of left and right lens-barrels respectively containing optical systems, a first guide shaft for supporting these lens-barrels in such a manner that the lens-barrels can slide in a direction perpendicular to the optical axes of the optical systems and can rotate, a second guide shaft for restraining the relative tilt of the lens-barrels around this first guide shaft in such a manner that the optical axes of the left and right optical systems become parallel to each other, a first rib for holding both ends of the first guide shaft by fitting upper and lower covers to each other, and a second rib for restraining the tilt of the optical axes of the entire lens-barrels around the first guide shaft.
