Claims

[Scope of utility model registration request]

A pair of left and right mirror bodies containing a built-in optical system are placed on both sides of the joint.
Each of the optical systems is supported so as to be rotatable within a certain range about an axis parallel to each optical axis of the optical system, and a drive shaft that is threadedly engaged with a rolling wheel is supported at the coupling portion, and a coupling portion of the drive shaft is provided. A blade is fixed to the protruding end, and a pair of objective lens frames or a pair of eyepiece frames is connected to each end of the blade so as to be slidable in each of the mirror bodies, and the rotating wheel is connected to the blade. In two-axis binoculars, the blades are moved in a direction toward and away from the joint by rotating the blades, and the focus is adjusted by moving a pair of lens frames connected to the blades in the same direction. Guide recesses are formed at both ends, and protrusions are integrally provided on the outer peripheral surfaces of the pair of lens frames to be connected to the blades, and these pair of lens frames are connected to each mirror body to which they fit. A focus adjustment mechanism for two-axis binoculars, characterized in that each projecting piece is brought into engagement with each guide recess so that it can rotate together with each fitted mirror body within a certain range about the rotation axis of the two-axis binoculars. . ,
