Zusammenfassung: | PURPOSE:To enlarge a speed reducing ratio of a power transmission path by arranging the outer periphery of a backward input gear in the axial direction to the outer periphery of an input gear to increase the outside diameter of the backward input gear. CONSTITUTION:Each forward input gear 17 is integral with a portion 23 projected forward, and the portion 23 is engaged with a backward input gear 13. The lower end portion 24 of the outer periphery of the backward input gear 13 is positioned below the uppermost portion of the outer peripheral edge 25 of an input gear 8, and the lower end portion 24 of the outer periphery of the backward input gear 13 is arranged in the axial direction to the upper portion of the outer periphery of the input gear 8. Accordingly, it is not necessary to consider interference of the backward input gear 13 with the input gear 8, so that the diameter of the backward input gear 13 can be increased to set a backward speed reducing ratio large. |
