Abstract
An endoscope includes a cap screw body rotatably mounted on a distal end member thereof and having a male threading means for mounting a cap, the cap detachably fitted on the distal end member and having a female threading means for threadably engaging with the cap screw body and a pin projectingly provided therein, and a fitting groove including an axial groove and a peripheral groove provided on the outer peripheral surface of the distal end member for fitting the pin, such that the cap is securely mounted by smoothly moving the pin along the fitting groove without binding between the male and female threading means while the pin moves within the peripheral groove.
