<p><P>PROBLEM TO BE SOLVED: To provide a rotary support structure of a carrier capable of regulating a position of a carrier not to allow displacement thereof in a thrust direction and supporting the same without suppressing rotation power, and capable of providing excellent rotation accuracy and efficient power transmission in a planetary gear reduction gear. <P>SOLUTION: An end part positioned in a rotary shaft 2 side of a first carrier 7 rotatably abuts on the casing 24 via an annular thrust bearing 19 arranged concentrically with the first carrier 7. A second sun gear 8 is provided with a projection part 8a projecting in an opposite side of the rotary shaft 2 along an axial center and having an end surface thereof formed in a spherical shape. A top part of the projection part 8a rotatably abuts on a second carrier 11. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
