影響しない。The screw rod 44 moves in the front-rear direction according to the left rotation or the right rotation of the operation wheel 43, and the interlocking arms 46a and 46b also move in the same direction accordingly. The rotation of the screw rod 44 during this operation is prevented by the moving body 45 being fitted into the two guide ridges 31c and 31d, and the interlocking arm 46a has the cutout hole 31a.
Since it moves in 1 and 32a 1 , it does not affect the objective lens barrel 32a.

すい双眼鏡となる。[Advantages of the Invention] As described above, the binoculars according to the present invention are configured such that the left and right lens barrels adjust the interpupillary distance by rotating the eyepiece lens barrel with the objective lens barrel as a rotation axis. Therefore, unlike the conventional example, the interpupillary adjustment mechanism and the focus matching mechanism do not have an integrated structure, and these mechanisms can be configured separately and then interlocked with each other. The binoculars have a simple structure and are easy to produce with few parts.

る。In addition, since the inner cylinder supporting the objective lens is internally provided in the objective lens barrel integrated with the cylindrical portion, it is possible to use a mechanical device between the inner barrel and the binocular body or between the lens barrel and the binocular body. The binoculars are capable of easily aligning the optical axes of the objective lens and the erecting optical system without causing any rattling.

As a result, the binoculars are easy to hold, have excellent operability for adjusting the interpupillary distance, and have a good appearance when used.
