Abstract
A gear is formed on the outer circumference of the disk unit 20a of the zoom operating member 20 and on the outer circumference of the right zoom drive member 18, and an intermediate gear 19 that engages and connects with each of these gears is located between them. In other words, the zoom operating member 20 and the right zoom drive member 18 are connected to each other in a non-integrated fashion. When the zoom operating member 20 is manually rotated around the eye distance adjustment axis 22, the right zoom drive member 18 rotates via the intermediate gear 19 and the left zoom drive member 21 simultaneously rotates via the connecting member 11.
