Abstract
A carrieris fixed to one end opening part of a circular cylindrical apparatus main body. A plurality of receiving holes, which extend in parallel with a rotation axis L, are formed in the carrierat the same interval in a peripheral direction. A planetary gearis received in each receiving holesuch that the planetary gearcan rotate on its own axis. An inner gearand a sun gear, which are arranged with their axes aligned with the rotation axis L of the apparatus main body, are disposed within the apparatus main body. The inner gearis engaged with the planetary gearsat the outside thereof. The sun gearis engaged with the planetary gearsat the inner side thereof. An engagement part between the inner gearand the planetary gearand an engagement part between the sun gearand the planetary gearare 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.
