Abstract
Five receiving holesextending along the axis of a circular cylindrical portionof a housing are formed in the circular cylindrical portion. Those five receiving holesare arranged at equal intervals in the peripheral direction of the circular cylindrical portion. Each receiving holerotatably receives therein a planetary gear. The respective planetary gearsare in engagement with an inner gearand a sun gear. The teeth of the inner gear, the sun gearand the planetary gearsare helical teeth. The numbers of teeth of the inner gear, the sun gearand the planetary gearsare set to 36, 24 and 6, respectively. As a result, the numbers of teeth of the inner gearand the sun gearlocated between adjacent two planetary gearsin the peripheral direction become 7.2 and 4.8, respectively, which are values each having a fraction below the decimal point.
