PROBLEM TO BE SOLVED: To simplify the structure of a freely restrainable and detachable restraining lock mechanism of a continuously driven structural member especially for adjusting a prescribed magnification of the continuous operational zoom system of a microscope, and to give an operability suitable to human engineering. SOLUTION: The restraining lock mechanism 1 is provided with a driving unit for zoom adjustment, a restraining disk 3 provided at a driving shaft 2 in the axial direction, and a restraining spring 4, and a ball 6 is provided between the spring 4 and the disk 3. The restraining spring 4 is constituted as a disk, and fixed to an equipment. The restraining disk 3 has prescribed lined-up grooves 8, and it is connected and fixed to the driving shaft 2. A restraining slider 5 equipped with an opening 7 is provided between the restraining spring 4 and the restraining disk 3. The ball 6 is provided at the opening 7 of the restraining slider 5 between the restraining spring 4 and the restraining disk 3, and the ball 6 can be guided through the restraining slider 5 to the grooves 8 of the restraining disk 3. |
