When the two convex hemispherical shells connected to each other are folded in half and their respective opening edges are aligned so as to correspond to the objective convex lens and the eyepiece concave lens, they project outward from the respective opening edges. When the provided storage locking claws are fitted into and locked in the storage locking grooves inside the opening edges of the corresponding hemispherical shells and stored in the sphere, and the storage locking claws in each hemispherical shell are pushed in from the outside. And spherical binoculars in which the storage locking claw is disengaged from the storage locking groove and can be used.

[0004] The hemispherical shell has a rectangular groove which is cut out in a required rectangular shape on the inner side and the outer peripheral side from the opening edge of the front surface, a support shaft crossing the rectangular groove is arranged, and one side of the hinge is inserted in the rectangular groove. The two hemispherical shells are foldably connected to the sphere and housed and pivotally connected to the support shaft, and an eyepiece opening penetrating the center of each hemispherical shell in and out is opened. Place the eyepiece concave lens in the hole,
Also, a front plate is inserted and arranged at the opening edge of each hemispherical shell, an opening for objective is formed at the center of each front plate, and a convex lens for objective is arranged in the opening for objective, and When the two hemispherical shells that are pivotally connected to each other correspond to the convex lens and the eyepiece concave lens, and are folded in two to match the respective opening edges, the storage locking claws projecting outward from the respective opening edges. Is inserted into the storage locking groove inside the opening edge of each corresponding hemispherical shell and stored in the sphere, and the storage locking claw portion of each hemispherical shell is pushed in from the outside. Spherical binoculars that can be put out of use from the storage locking groove and used can be used.

The notched groove may be formed in a part of the side circumference from the opening edge of the hemispherical shell at the time of molding, and a ridge having a moderating projection at the tip may be provided in the middle thereof.

When the hemispherical shell is folded into a sphere, the storage locking claws projecting outward from the outer diameter edge of the front plate are formed at positions inconsistent with each other. A storage locking groove corresponding to the locking claw may be formed and engaged with each other to maintain the two connected hemispherical shells in a folded sphere.
