Abstract
A binocular has the right and left optical systems. A distance between these optical systems is variable for an adjustment of the pupil distance. A protecting member is arranged to protect objective lenses and eyepieces of the optical systems by sheltering them when the binocular is housed. The protecting member is movable to release the sheltering condition to expose the lenses and the eyepieces when the binocular is used. The protecting member is driven in liaison with an operation of the adjustment of the pupil distance.
