PURPOSE:To make an observation in the best state by providing an optical reflecting member whose angle is adjustable in front of the objective part of a hard endoscope. CONSTITUTION:An angle adjusting ring 2 is rotted to tense and loosen an interlocking wire 7, and thus the tilt angle of an optical reflecting member fixing part 3 is adjusted. The fixing plate 3 is expected to return to a specific position through the operation of a leaf plate 12 during the adjustment, but a steel ball 5 pressed with a spring 6 provided to a main body 1 engages a radial groove formed in the abutting surface of the angle adjusting ring 2 to make a click stop and the inclination of the fixing plate 3, i.e. optical reflecting member 15 is maintained. The tilt angle is about 0-45 deg. to the optical axis.
