双眼鏡の焦点調整装置。A long hole in the longitudinal direction is bored in the pivot made of a cylindrical shaft, a control pin is provided protruding from the outer periphery of the central shaft inserted into the pivot, and this control pin is made to protrude outward from the long hole of the pivot, and the A fixed base that is inserted into the pivot and a main body case placed on the fixed base are formed, and the flat base of the fixed base and the bottom wall of the case body have a long hole that overlaps and penetrates the long hole of the pivot. The interior of the case body is divided into a sliding chamber with a long hole sandwiched between two partition walls, and a slider is slidably installed in the sliding chamber. is formed by integrally forming an upper plate part and a lower plate part extending left and right on the upper and lower surfaces respectively, and providing rack parts on the inner wall of the lower plate part on one side and the inner wall of the upper plate part on the other side. Then, spur gears are installed on both sides of the slider and meshed with each rack part, and the tips of each gear shaft protrude from the bulkhead to the outside of the left and right side walls, and the protruding tips of the left and right gear shafts are fitted with respective spur gears. In a focusing device with a handle fixedly installed, a drum having a scale indicating focal length on the outer periphery is rotatably installed on the front end of the case body, a gear is fixedly installed on the gear shaft of one handle, and A focus adjustment device for binoculars constructed by integrally installing a gear on one end of a drum, and meshing these two gears via an intermediate gear, so that the drum can rotate freely in conjunction with handle operation.
