In a sight scope, an erect sleeve is received in a scope body. An erect lens system is disposed within the erect sleeve. An erect lens system is pivotably supported at its end portion on the side of an eye piece by the scope body. The other end portion of the erect sleeve on the side of an objective is biased by a spring so as to contact an inner end face of an adjusting member of an inclination adjusting mechanism. The end portion of the erect sleeve on the side of the objective is moved by the adjusting member in a direction perpendicular to an axis of the scope body. By this, the erect sleeve is adjusted in its angle of inclination with respect to the axis of the scope body. A projection is formed on that end portion of the erect sleeve on the side of the objective. The projection is tapered when viewed in a direction perpendicular to the axis of the scope body. A top portion of this project is in contact with the inner end face of the adjusting member.
