る対物レンズの固定構造。 An endoscopy system in which an objective lens for direct viewing or a side viewing objective lens is fixed on the rigid tip at the tip of the guiding tube by screwing the mounting nut onto the screw on the rigid tip. In the fixing structure of an objective lens in a mirror, a coil spring is arranged around the outer periphery of the rigid tip and the mounting nut, so that one side of the coil spring wraps around the rigid tip and the other side wraps around the mounting nut. A fixing structure for an objective lens in an endoscope, characterized in that a coil is wound in a direction in which the mounting nut is tightened in the diametrical direction when set and the mounting nut is tightened when the mounting nut tries to loosen from the screw.
