像を接眼レンズによつて拡大するようにされてい
る。(Prior art) In sighting scopes such as rifle scopes, an objective lens, a condensing lens, an orthogonal lens, and an eyepiece are built into the scope body. Once an erect image is formed within the scope body, this image is further magnified by an eyepiece.
上記正立像を射手が明確に視認するためには、
正立像と接眼レンズとの距離が極めて重要となる
が、この距離は射手の視力によつて微妙な個人差
がある。 In order for the shooter to clearly see the erect statue above,
The distance between the erect image and the eyepiece is extremely important, but this distance varies slightly depending on the shooter's visual acuity.
そこで、一般にスコープ本体の接眼側に接眼外
筒と接眼内筒とを設け、正立レンズが内蔵された
上記接眼内筒を接眼外筒に螺合させておき、接眼
内筒を回動することによつて接眼内筒がねじの作
用により接眼外筒を進退動し、正立像と接眼レン
ズとの距離の微妙な調節、いわゆる視度調節がで
きるようにされている。 Therefore, generally an eyepiece outer cylinder and an eyepiece inner cylinder are provided on the eyepiece side of the scope body, and the eyepiece inner cylinder with the built-in erecting lens is screwed into the eyepiece outer cylinder, and the eyepiece inner cylinder is rotated. The inner tube of the eyepiece moves forward and backward with the outer tube of the eyepiece by the action of a screw, making it possible to finely adjust the distance between the erect image and the eyepiece, or so-called diopter adjustment.
（考案が解決しようとする問題点）
しかしながら、上記従来の照準スコープにおい
ては、射撃した際の衝撃で接眼内筒が振動し、こ
の振動によつて接眼内筒が僅かづつ回動してしま
うため、正立像と接眼レンズとの距離が狂い、そ
の結果、頻繁に視度調節を行わなければならない
という欠点があつた。(Problem to be solved by the invention) However, in the above-mentioned conventional sighting scope, the eyepiece inner tube vibrates due to the impact when shooting, and this vibration causes the eyepiece inner tube to rotate slightly. However, the distance between the erect image and the eyepiece lens is incorrect, and as a result, the diopter must be adjusted frequently.
特に、視度調節時の接眼内筒の回動角度に対し

眼外筒のねじのリードを大きくした場合には、ね
じのリード角が大きくなり、したがつて比較的に
小さな力で接眼内筒が回動するようになるので、
上記欠点は顕著となる。 In particular, if the lead of the screw between the eyepiece inner cylinder and the eyepiece outer cylinder is increased so that the forward and backward movement dimensions become larger relative to the rotation angle of the eyepiece inner cylinder when adjusting the diopter, the lead angle of the screw becomes large. Therefore, the eyepiece inner tube can be rotated with a relatively small force.
The above drawbacks become noticeable.

側へ付勢されているので、接眼外筒の雌ねじ部と
接眼内筒の雄ねじ部との摩擦抵抗が増加し、接眼
内筒が回動し難くなる。(Effect of the invention) As explained above, according to this invention, since the eyepiece inner cylinder screwed into the eyepiece outer cylinder is urged toward the eyepiece side by the elastic body, the female thread of the eyepiece outer cylinder This increases the frictional resistance between the eyepiece inner cylinder and the male threaded portion of the eyepiece inner cylinder, making it difficult for the eyepiece inner cylinder to rotate.
その結果、正立像の結像位置と接眼レンズ間の
距離を常に一定に維持させることができ、射手は
標的を明確に視認することができる。 As a result, the distance between the imaging position of the erect image and the eyepiece can always be maintained constant, and the shooter can clearly see the target.
又、接眼内筒の雄ねじ部のねじ山と接眼外筒の
雌ねじ部のねじ山との間にスコープ本体の軸芯方
向の隙間があるので、射撃した際の反動で照準ス
コープに接眼方向への力が作用した場合に、接眼
外筒がこの隙間寸法だけ接眼側へスライドし、弾
性体が緩衝体として機能し、射手を衝撃から保護
する。 Additionally, since there is a gap in the axial direction of the scope body between the threads of the male thread of the inner eyepiece cylinder and the threads of the female thread of the outer eyepiece cylinder, the recoil when shooting can cause the aiming scope to move in the eyepiece direction. When a force is applied, the eyepiece outer tube slides toward the eyepiece by this gap, and the elastic body functions as a buffer to protect the shooter from impact.
