<P>PROBLEM TO BE SOLVED: To guide lubricating oil supplied from an interior of a shaft to a part to be lubricated disposed on an outer periphery of the shaft without requiring a special lubricating oil guide member. <P>SOLUTION: A cotter member 96 is fitted in an annular groove 16a formed on an outer peripheral surface of a main shaft 16, and by covering an outer periphery of the cotter member 96 by a retainer 97 and retaining it in the annular groove 16a, a sun gear 72 fitted on the outer peripheral surface of the main shaft 16 can be fixed by the cotter member 96 so as not to move in an axis L direction. Since the lubricating oil supplied through a lubricating oil supply hole 16c opened on the outer peripheral surface of the main shaft 16 from a lubricating oil supply passage 16b formed in the interior of the main shaft 16 is guided to a forward clutch 78 disposed on an outer periphery of the main shaft 16 by a lubricating oil guide part 97c of the retainer 97, the lubricating oil can be supplied to the forward clutch 78 without providing a special lubricating oil guide member, and the number of parts is reduced. <P>COPYRIGHT: (C)2011,JPO&INPIT |
