PURPOSE:To execute installation easily and quickly, by providing a release means for always energizing like turning so that a pin is shifted to the inside of a spiral groove part by an elastic member which is provided with a cam body in the circumferential direction of an inserting port part, and for shifting the pin to the groove part in the diameter direction by turning the cam body against said energizing. CONSTITUTION:As for a release ring 20 which has been connected and fixed to a cam body 17 by this cam body and a connecting plate 23 by a spring 26, energizing force is always provided clockwise, and in a state that an endoscope eyepiece part 3 has been installed, a pin 14 of each fitting piece 11 is in the end part of the inside in the diameter direction of an inclined groove 18C or at a position being near said part, a fitting part 16 of the tip of the fitting piece 11 presses and detains a tapered reverse side 4 of the eyepiece part 3 by leastic force by a spring 12, and also the spring 26 and the outside circumferential wall surface of the inclined groove part 18C are made to press- contact and are detained, by which this device is constituted so that an endoscope 1 is detained firmly enough by the fitting piece 11 projected to the inside of an inserting port part 6. |
