A driving gear 2g, an intermediate gear 4g and a driven gear 3g are internally packaged in the gear box 1. The driving gear 2g includes a driving shaft 21 in the center, and the driven gear 3g includes a driven shaft 31 in the center. Rotation of the driving gear 2g can be transferred to the driven gear 3g via the intermediate gear 4g. The connection metal fitting 2 is fixed in a distal end of the driving shaft 21 protruding from one surface of the gear box 1 and can be connected with a tip of an insulation operation rod 7. The cylindrical holder 3 is fixed in a tip of the driven shaft 31 protruding from the other surface of the gear box 1 and an end face is opened so as to accommodate a nut 9n and a nut falling prevention cap 9c therein.</p> |
