1. An apparatus for suppressing noise produced in a planetary gear device, comprising:
an inner gear having a first movement limiting feature formed on an outer peripheral surface of the inner gear, the first movement limiting feature extending in an axial direction from one side of the inner gear to another side of the inner gear, wherein the first movement limiting feature is formed in a first direction that is inclined with respect to the axial direction; and
a housing having a second movement limiting feature formed on an inner surface of the housing that extends in the first direction that is inclined with respect to the axial direction, wherein the housing is configured to contain the inner gear in an interior of the housing such that the inner gear is a floating inner gear with a gap that is created between the inner peripheral surface of the housing and the outer peripheral surface of the inner gear, and
wherein movement of the inner gear within the interior of the housing is limited through two separate linear contacts between the first movement limiting feature and the second movement limiting feature.
