PURPOSE:To select speed reduction ratio to a wide range, by forming a long distance between an intermediate shaft, performing speed reduction, and an output shaft, that is, by arranging the intermediate shaft to the side of an input shaft and the output shaft similarly to the side of the input shaft oppositely to the intermediate shaft. CONSTITUTION:An intermediate shaft 19 is located diagonally to the upper side of an input shaft 13, and an output shaft 25 is positioned to the lower part of the input shaft 13. Transmitted power to the input shaft 13 is transmitted to an input gear 14, intermediate gear 22 and minor gear 20, then transmitted from said minor gear 20 to a major gear 26 on the output shaft 25. In this case, the intermediate shaft 19, mounted with the minor gear 20, and the output shaft 25, mounted with the major gear 26, are located at an opposite side by interposing the input shaft 13, accordingly a long distance between the intermediate shaft and the output shaft is obtained, in this way, speed reduction ratio can be selected throughout a wide range. |
