法によって曲げモーメントを連続調整することは不可能
である。Threaded pressure elements and bearings are often prevented from twisting by fixing the pressure element with a bolt together with the cylinder and the arm of the hand that adjusts the required moment. However, 1
However, with this known solution it is not possible to continuously adjust and set the bending moment of the bridge, and since each bearing is connected by two cylindrical fits, the slack in this joint is relatively large and both The drawback is that the lens barrel is no longer parallel. In addition, the cutting process required to determine the bending moment of the joint bridge of the twin OR mirror is expensive, and the fixing elements are subject to severe wear, making it impossible to continuously adjust the bending moment using well-known technical solutions. It is possible.

式ブリッジ用軸受円筒を提(j先することである。The object of the present invention is to install three binion heads between the hinge arms.
91t, bending moment can be set and adjusted continuously,
Even if the folding bridge is bent (=J), the bending position can be maintained without requiring an additional fixed east cable, the fitting can be minimized, the parallelism r1 of the binocular halves can be increased, and the cost can be reduced. The purpose of the present invention is to provide a bearing cylinder for a folding bridge of binoculars that does not require such cutting and removal process.
