ABSTRACT:
A carrier2is fixed to one end opening part of a circular cylindrical apparatus main body1. A plurality of receiving holes2d, which extend in parallel with a rotation axis L, are formed in the carrier2at the same interval in a peripheral direction. A planetary gear4is received in each receiving hole2dsuch that the planetary gear4can rotate on its own axis. An inner gear5and a sun gear9, which are arranged with their axes aligned with the rotation axis L of the apparatus main body1, are disposed within the apparatus main body1. The inner gear5is engaged with the planetary gears4at the outside thereof. The sun gear9is engaged with the planetary gears4at the inner side thereof. An engagement part between the inner gear5and the planetary gear4and an engagement part between the sun gear9and the planetary gear4are 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.
