<P>PROBLEM TO BE SOLVED: To realize a structure capable of sufficiently securing the durability of a planetary gear type transmission by efficiently feeding lubricating oil to radial needle bearings 31a and 31b assembled in the planetary gear type transmission and removing foreign matters mixed in the lubricating oil. <P>SOLUTION: The lubricating oil is fed from a reference lubricating oil passage 50 formed in an input shaft 5 to the radial needle bearings 31a and 31b through lubricating oil holes 56 and 57, a space 58a, a recessed part 61, and lubricating oil passages 53a and 53b. A filter 64 is installed at the upstream side end part of an oil supply passage 53a to collect foreign matters mixed in the lubricating oil. Thus, the clean lubricating oil can be fed to the radial needle bearings 31a and 31b. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
