Abstract: Five receiving holes 2e extending along the axis of a circular cylindrical portion 2b of a housing are formed in the circular cylindrical portion 2b. Those five receiving holes 2e are arranged at equal intervals in the peripheral direction of the circular cylindrical portion 2b. Each receiving hole 2e rotatably receives therein a planetary gear 5. The respective planetary gears 5 are in engagement with an inner gear 3 and a sun gear 4. The teeth of the inner gear 3, the sun gear 4 and the planetary gears 5 are helical teeth. The numbers of teeth of the inner gear 3, the sun gear 4 and the planetary gears 5 are set to 36, 24 and 6, respectively. As a result, the numbers of teeth of the inner gear 3 and the sun gear 4 located between adjacent two planetary gears 5 in the peripheral direction become 7.2 and 4.8, respectively, which are values each having a fraction below the decimal point.

A plurality of receiving holes 2d, which extend in parallel with a rotation axis L, are formed in the carrier 2 at the same interval in a peripheral direction. A planetary gear 4 is received in each receiving hole 2d such that the planetary gear 4 can rotate on its own axis. An inner gear 5 and a sun gear 9, which are arranged with their axes aligned with the rotation axis L of the apparatus main body 1, are disposed within the apparatus main body 1. The inner gear 5 is engaged with the planetary gears 4 at the outside thereof. The sun gear 9 is engaged with the planetary gears 4 at the inner side thereof. An engagement part between the inner gear 5 and the planetary gear 4 and an engagement part between the sun gear 9 and the planetary gear 4 are displaced from each other in a direction of the rotation axis L so that they are not overlapped with each other in a direction of the rotation axis L.

Abstract: A planetary gear 5 is contacted at its at least one tooth of all its teeth 51n with an end edge 23d facing an inner releasing part 23c of an inner peripheral surface of a receiving hole 23a irrespective of a rotational position of the planetary gear 5. By doing so, the planetary gear 5 is prevented from moving in the radial direction. As a result, the planetary gear 5 can be prevented from vibrating in the radial direction. Thus, vibrations of a planetary gear apparatus can be reduced, and the planetary gear and a carrier can be reduced in damage.

Abstract: A receiving portion 2e for rotatably receiving therein a planetary gear 3, is formed between a plurality of retaining protrusions 2d of a carrier. A connection portion 2f extending annularly about a rotation axis L is formed on an outer peripheral of a distal end portion of each retaining protrusion 2d. Through this connection portion 2f, the distal end portions of the respective retaining protrusions 2d are connected to each other. Owing to this arrangement, each retaining protrusion 2d is reinforced to minimize its deformation. As a result, deformation of the receiving portion 2e is greatly reduced and the planetary gear 3 receiving in the receiving portion 2e can rotate smoothly.
