<P>PROBLEM TO BE SOLVED: To provide a final reduction gear simplifying a support structure for the output gear of a final reduction gear device and a planetary gear. <P>SOLUTION: An angular ball bearing 18 as a radial bearing is used as a bearing member supporting a bevel ring bear 142 (a final gear device 14) and the planetary gear 16 (a bearing housing 15). The angular ball bearing has load capability with respect to a radial load and an axial load, and is formed with a flange portion 181a which is provided to an outer race 181 and is provided as a projecting portion extending toward the inner peripheral surface of the bevel ring gear 142 in order to be joined to the inner peripheral surface of the bevel ring gear 142. Further, the inner peripheral surface of the bevel ring gear 142 is formed with an engagement projecting portion 142c joined to one end surface of the flange portion 181a, and the bevel ring gear 142 and bearing housing 15 are connected and fixed to each other with both end surfaces of the flange portion 181a sandwiched between the engagement projecting portion 142c and the baring housing 15. <P>COPYRIGHT: (C)2009,JPO&INPIT |
