の遊星クラツチ機構。[Claims for Utility Model Registration] 1. A sun gear rotationally driven by a drive source, a driven gear connected to a load driven by the drive source, and meshing with the driven gear when the sun gear rotates forward. In a planetary clutch mechanism comprising a planetary gear that is driven to revolve in a meshing section and in a retraction section that releases the meshing when the rotation is reversed, the planetary gear is in the retraction section within the orbit of the planetary gear. A planetary clutch mechanism characterized in that it is provided with a blocking member that meshes with the teeth of the planetary gear and prevents the planetary gear from rotating. 2. The planetary clutch mechanism according to claim 1, wherein the planetary gear is stopped in a state in which it passes over the blocking member within the retraction section. 3. The planetary clutch mechanism according to claim 1, wherein the blocking member is a gear having a load in the direction of rotation.
