Claims

[Claims for Utility Model Registration] A carrier that rotatably supports a plurality of planetary gears on a rotating circumference, a sun gear that externally meshes with the planetary gear, a ring gear that internally meshes with the planetary gear, and either the sun gear or the ring gear. an input member connected to one of the two, a fixable fixing means capable of fixing the other, an output member connected to the carrier, and the carrier;
direct coupling means capable of directly coupling any two of a sun gear and a ring gear, and when the fixing means is fixedly operated, the output member is rotated at a slower speed than the input member, and the direct coupling means is directly coupled. In a planetary gear mechanism that, when activated, releases the fixing operation of the fixing means and rotates the output member at the same speed as the input member, the number of revolutions of the input member is detected and a signal is sent to the direct coupling means. A rotation speed detecting means for outputting an output is provided, and when the rotation speed of the input member is below a first predetermined value and when it is above a second predetermined value larger than the first predetermined value, the direct coupling means is actuated to directly connect the output member. is rotated at the same speed as the input member, and when the rotation speed of the output member is between a first predetermined value and a second predetermined value, the fixing means is actuated to rotate the output member from the input member. A planetary gear mechanism characterized by a planetary gear mechanism that rotates at a reduced speed.
