PROBLEM TO BE SOLVED: To obtain an electrode position adjusting mechanism which can easily, speedily, and accurately adjust the interval between discharge electrodes irrelevantly to whether the optical fiber fused splicing machine is in discharge fused splicing operation. SOLUTION: One of an anode and a cathode which face each other is assigned as a fixed electrode rod 1 and the other is assigned as a movable electrode rod 2; and a piezoelectric element 5 is interposed between one end of a lever 6 supported on a fulcrum 7 and a support surface, the other end of the lever 6 tables action on the movable electrode rod 2, which is pressed by a return spring 8 in the separating direction from the fixed electrode rod 1 to move the movable electrode rod 2 by the lever 7 against the return spring 8. Then a voltage is applied to the piezoelectric element 5, which is expanded to drive the lever 6, thereby reducing the discharge interval. |
