Claims

[Scope of utility model registration request]

A hollow central shaft located in the center of the left and right mirrors of the binoculars, an elevating shaft mounted within the central shaft so as to be slidable in the axial direction, and an elevating shaft mounted at one end of the elevating shaft that moves the eyepiece mechanism in the vertical direction. a blade shaft that drives the blades to be moved; a center wheel rotatably attached to the outer periphery of the center shaft; and a vertical movement mechanism that moves the lifting shaft up and down by rotation of the center wheel. In the diopter adjustment mechanism for binoculars, the diopter adjustment mechanism includes an insertion hole bored in the middle of the vertical axis, a coil spring and a ball inserted into the insertion hole, and a coil spring and a ball provided on the inner surface of the central axis at the zero diopter position. A diopter adjustment mechanism for binoculars, comprising a concave groove into which a part of a ball pushed by a coil spring in an insertion hole fits.
