徴とする固定焦点型双眼鏡。 In fixed-focus binoculars in which the eyepieces are held at a constant distance from the objective lens, a pair of eyepiece barrels held in the binocular body are fixed to the binocular body side, and a fixed barrel part is attached to the binocular body. The proximal end of the lens holder is made up of a cylindrical body with an eyepiece mounted inside the movable cylindrical part, and the distal end of the lens holder can be slid into the fixed cylindrical part. The distal end of the adjustment lever is engaged with the engagement part formed on the outer peripheral surface of the lens holder through the through hole formed in the fixed cylinder part, and the adjustment lever can be moved relative to the fixed cylinder part by operating the adjustment lever. Fixed-focus binoculars characterized by being configured so that the distance of the tube portion can be changed.
