Claims

[Scope of Claim for Utility Model Registration] An actuator having a planetary gear reduction mechanism driven by a driving motor, comprising: a housing that holds the driving motor, a planetary gear reduction mechanism that is fixed to the housing, an internally toothed sun gear; A planetary gear that fits into and meshes with the sun gear, has a slightly smaller diameter and fewer teeth than the sun gear, and a core that is concentrically connected to the output shaft of the driving motor and is fitted into the center of the sun gear for pivotal support. and a support shaft integrally having an eccentric shaft part that pivots the planetary gear so that it revolves inside the sun gear, and the planetary gear of the planetary gear reduction mechanism has a rotation radius of the planetary gear. An actuator comprising an output member that extracts the rotation of the planetary gear by engaging with the play.
