摘要： An optical device includes an impact position adjusting part which is an operation adjusting part. The impact position adjusting part includes a rotating operation part, a shaft part, a fixed tubular part which is a first tubular part formed with outer peripheral recesses-projections, and a rotating tubular part which is a second tubular part formed with inner peripheral recesses-projections. According to an operation of a user, the rotating operation part moves together with the rotating tubular part to a rotatable position at which the outer peripheral recesses-projections and the inner peripheral recesses-projections are separated, and a rotation prohibited position at which the outer peripheral recesses-projections and the inner peripheral recesses-projections are engaged. In a vicinity of an end part on a side close to the rotating tubular part, a width of a projection of the outer peripheral recesses-projections of the fixed tubular part gradually decreases toward the end part.

摘要： Provided is an optical sight having a lens frame and multiple fixing members for fixing an objective lens to an inside of a barrel body. The objective lens is held on an inner peripheral surface of a lens frame. A male screw, which can be screwed into a female screw arranged on the inner peripheral surface of a barrel body, is arranged on an outer peripheral surface of the lens frame. Multiple through-holes are formed at a wall section of the lens frame corresponding to the outer peripheral surface of the objective lens along a circumferential direction of the wall section. The fixing member is made of metal or synthetic resin having a hardness lower than that of the barrel body. An assembly including the objective lens, the lens frame, and the fixing members is screwed into the female screw arranged on the inner peripheral surface of the barrel body.
